SIMOCODE 3UF Motor Management and Control Devices

SIMOCODE pro 3UF7

motor management and control devices

■

Overview

■

Design

SIMOCODE pro is a flexible, modular motor management sys-

tem for motors with constant speeds in the low-voltage perfor-

mance range. It optimizes the connection between I&C and

motor feeder, increases plant availability and allows significant

savings to be made for startup, operation and maintenance of a

system.

General

SIMOCODE pro is a modularly constructed motor management

system which is subdivided into two device series with different

functional scopes:

• SIMOCODE pro C

• SIMOCODE pro V

When SIMOCODE pro is installed in the low-voltage switchgear

cabinet, it is the intelligent interface between the higher-level

automation system and the motor feeder and includes the

following:

Both series (systems) are made up of different hardware

components (modules):

System

SIMOCODE pro C

SIMOCODE pro V

• Multifunctional, solid-state full motor protection which is

independent of the automation system

Modules

• Basic unit 1

• Basic unit 2

• Flexible software instead of hardware for the motor control

• Detailed operational, service and diagnostics data

• Open communication through PROFIBUS DP, the standard for

fieldbus systems

• Current measuring module • Current measuring module or

current/voltage measuring

voltage

• Operator panel (optional)

• Expansion modules

(optional)

Per feeder each system always comprises one basic unit and

one separate current measuring module. The two modules are

connected together electrically through the system interface

with a connection cable and can be mounted mechanically

connected as a unit (one behind the other) or separately (side

by side). The motor current to be monitored is decisive only for

the choice of current measuring module.

An operator panel for mounting in the control cabinet door is

optionally connectable through a second system interface on

the basic unit. Both the current measurement module and the

operator panel are electrically supplied by the basic unit through

the connection cable. More inputs, outputs and functions can be

added to basic unit 2 (SIMOCODE pro V) by means of optional

expansion modules, thus supplementing the inputs and outputs

already existing on the basic unit.

All modules are connected together by connection cables.

The connection cables are available in various lengths. The

maximum distance between the modules (e.g. between the

basic unit and the current measurement module) must not

exceed 2 m. The total length of all the connection cables in a

single system must not be more than 3 m.

SIMOCODE pro designed for mixed operation

Depending on functional requirements, the two systems can be

used simultaneously without any problems and without any addi-

tional outlay in a low-voltage system. SIMOCODE pro C is fully

upward-compatible to SIMOCODE pro V. The same compo-

nents are used. The parameterization of SIMOCODE pro C can

be transferred without any problems. Both systems have the

same removable terminals and the same terminal designations.

2 system interfaces for connection of

• a current measuring module or current/voltage measuring

module

Current measuring modules for the following current ranges are

offered:

• 0.3 ... 3 A with straight-through current transformer

• 2.4 ... 25 A with straight-through current transformer

• 10 ... 100 A with straight-through current transformer

• 20 ... 200 A with straight-through current transformer or

busbar connection

• expansion modules and

• an operator panel

Basic unit 2 is suitable for standard rail mounting or, with

additional push-in lugs, for fixing to a mounting plate.

• 63 ... 630 A with busbar connection

Current measuring modules (current ranges)

For motor currents up to 820 A, a current measuring module for

0.3 ... 3 A, for example, can be used in combination with a

3UF1 8 interposing/current transformer.

The current measurement module is selected for each feeder

according to the rated motor current to be monitored. Various

current measurement modules for current ranges from 0.3 to

630 A are available for this purpose. The current measurement

module is connected to the basic unit by a connection cable and

is supplied with electricity by the basic unit through this connec-

tion cable. Current measurement modules up to 100 A are suit-

able for standard rail mounting or can be fixed directly to the

mounting plate by means of additional push-in lugs. Similarly,

current measurement modules up to 200 A can also be mounted

on standard mounting rails or be fixed directly to mounting

plates by means of fixtures integrated in the housing. Finally, cur-

rent measuring modules up to 630 A can only be mounted with

the integrated screw fixtures.

Current/voltage measuring modules (voltage range)

Current/voltage measuring modules have the same functions as

the current measuring modules. However, they can only be used

in combination with basic unit 2. They offer the same current

ranges for the rated motor current. Mounting on standard mount-

ing rails, on mounting plates or directly on the contactor is also

the same as with the current measuring modules. They can also

measure voltages up to 690 V in the main circuit, which is nec-

essary for calculating or monitoring power-related measured

variables. Current/voltage measuring modules have additional

removable terminals, to which the voltages of all three phases of

the main circuit are connected (3-pole). An additional 3-core

cable can be used, for example, to directly connect the main cir-

cuit from the busbar terminals of the current/voltage measuring

modules to the voltage measuring terminals.

Note:

Current measuring modules for up to 100 A set current can be

mechanically connected to the corresponding basic unit and

mounted with it as a unit (one behind the other). For larger

current measuring modules, only separate mounting is possible.

Note:

Current/voltage measuring modules can only be mounted

separately from the associated basic unit 2. A current/voltage

measuring module can only be used with a basic unit 2, product

version E02 and later (from April 2005).

motor management and control devices

Operator panel

Expansion with additional binary I/Os through digital

modules

The operator panel is used to control the motor feeder and can

replace all conventional pushbuttons and indicator lights to save

space. This means that SIMOCODE pro or the feeder can be

operated directly at the control cabinet and that the system

interface is connected externally for easier parameterization or

diagnostics using a PC/PG, for example.

Up to two digital modules can be used to add additional binary

inputs and relay outputs to basic unit 2. The input circuits of the

digital modules are supplied from an external power supply. The

following variants are available:

• 4 inputs, supplied externally with 24 V DC and 2 monostable

relay outputs

The operator panel is connected to the basic unit over a

connection cable from its rear system interface and is supplied

electrically from the basic unit.

• 4 inputs, supplied externally with 110 ... 240 V AC/DC and 2

monostable relay outputs

• 4 inputs, supplied externally with 24 V DC and 2 bistable

relay outputs

The operator panel has 5 freely assignable buttons and a total of

10 LEDs, of which 7 LEDs can be used as required and

assigned to any status signal.

• 4 inputs, supplied externally with 110 ... 240 V AC/DC and 2

bistable relay outputs

A PC/PG can be connected to the front system interface over the

PC cable.

Up to two digital modules can be connected to one basic unit 2.

All variants can be combined with each other.

The operator panel is mounted in the control cabinet door or the

front plate of, for example, a withdrawable unit and satisfies IP54

degree of protection with the system interface covered.

With basic unit 2 (SIMOCODE pro V), it is possible to expand the

number and type of inputs and outputs in order to implement

additional functions, for example. Each expansion module has

two system interfaces on the front. Through the one system

interface the expansion module is connected to the system

interface of basic unit 2 using a connection cable, for example;

through the second system interface, further expansion modules

or the operator panel can be connected. The power supply for

the expansion modules is provided by the connection cable

through basic unit 2.

For the implementation of some motor control functions, in

addition to the relay outputs on basic unit 2, at least one further

digital module is required.

Expansion with a ground fault measuring module with an

external summation current transformer

Expansion of analog temperature monitoring with a

temperature module

Instead of ground fault monitoring using the current measuring

modules or current/voltage measuring modules, it may be

necessary, especially in high-impedance grounded networks, to

implement ground fault monitoring for smaller ground fault

currents using a summation current transformer. A ground fault

module can be used to add an additional input to basic unit 2 for

connection of a summation current transformer (3UL2 20.-.A).

Independently of the thermistor motor protection of the basic

units, up to 3 analog temperature sensors can be evaluated

using a temperature module.

The temperatures measured here can be completely integrated

in the process, monitored and supplied to a higher-level

automation system. The temperature module can be used, for

example, for analog monitoring of the temperature of the motor

windings or bearings or for monitoring the coolant or gear oil

temperature. Various sensor types are supported (resistance

sensors) for use in solid, liquid or gaseous media:

• PT100/PT1000

Maximum one ground fault module can be connected to one

basic unit 2.

• KTY83/KTY84

• NTC

Maximum one temperature module can be connected to one

basic unit 2. The same sensor type must be used in all sensor

measuring circuits.

Expansion with additional inputs/outputs by means of an

analog module

Safe isolation

All circuits in SIMOCODE pro are safely isolated from each other

in according to IEC 60947-1. That is, they are designed with

double creepage and air distances. In the event of a fault,

therefore, no parasitic voltages can be formed in neighboring

circuits. The instructions of test report No. 2668 must be

complied with.

Basic unit 2 can be optionally expanded with analog inputs and

outputs (0/4 ... 20 mA) by means of the analog module. It is then

possible to measure and monitor any process variable that can

be mapped on a 0/4 ... 20 mA signal. Typical applications are,

for example, level monitoring for the implementation of dry run-

ning protection for pumps or monitoring the degree of pollution

of a filter using a differential pressure transducer. In this case the

automation system has free access to the measured process

variables. The analog output can be used, for example, to visu-

alize process variables on a pointer instrument. The automation

system also has free access to the output.

EEx e and EEx d types of protection

The overload protection and the thermistor motor protection of

the SIMOCODE pro system comply with the requirements for

overload protection of explosion-protected motors to the degree

of protection:

• EEx d "flameproof enclosure" e.g. according to EN 50018 or

EN 60079-1

• EEx e "increased safety" e.g. according to EN 50019 or

EN 60079-7

SIMOCODE 3UF Motor Management and Control Devices

SIMOCODE pro 3UF7

motor management and control devices

■

Function

Multifunctional, solid-state full motor protection

Monitoring of adjustable limit values for the motor current

• Current limit value monitoring is used for process monitoring

independent of overload protection. Violation of a current limit

value below the overload threshold can be an indication for a

dirty filter in a pump or for an increasingly sluggish motor

bearing, for example. Violation of the lower current limit value

can be a first indication of a worn drive belt. SIMOCODE pro

supports two-step monitoring of the motor current for freely

selectable upper and lower current limit values. The response

of SIMOCODE pro can be freely configured and delayed if it

reaches an alarm or tripping threshold.

Current-dependent electronic overload protection with

adjustable tripping characteristics (Classes 5, 10, 15, 20, 25, 30,

35 and 40)

• SIMOCODE pro protects three-phase or AC motors according

to IEC 60947-4-1 requirements. The trip class can be adjusted

in eight steps from Class 5 to Class 40. In this way, the break

time can be adapted very accurately to the load torque which

allows the motor to be utilized more effectively. In addition, the

time until the overload tripping operation is performed is

calculated and can be made available to the I&C system. After

an overload tripping operation, the remaining cooling time can

be displayed (characteristic curves for 2-pole and 3-pole

loading in SIMOCODE pro System Manual).

3)

Voltage monitoring

• By measuring the voltage directly at the circuit-breaker or at

the fuses in the main circuit, even when the motor is

deactivated, SIMOCODE pro can also obtain information

about the reclosing capability of the feeder and signal it if

required.

Phase failure/unbalance protection

• The level of the phase unbalance can be monitored and trans-

mitted to the I&C system. If a specified limit value is violated,

a defined and delayable response can be initiated. If the

phase unbalance is larger than 50 %, the tripping time is also

automatically reduced according to the overload characteris-

tic since the heat generation of the motors increases in unbal-

anced conditions.

• SIMOCODE pro supports two-stage undervoltage monitoring

for freely selectable limit values. The response of

SIMOCODE pro can be freely configured and delayed if it

reaches an alarm or tripping threshold.

3)

Monitoring the active power

• The active power characteristic of a motor provides an

accurate statement of the actual loading over the complete

range. Excessive loading will cause increased wear in the

motor and can result in early failure. Insufficient active power

can be an indication of, for example, motor idling.

• SIMOCODE pro supports two-step monitoring of the active

power for freely selectable upper and lower current limit

values. The response of SIMOCODE pro can be freely

configured and delayed if it reaches an alarm or tripping

threshold.

Stall protection

• If the motor current rises above an adjustable blocking

threshold (current threshold), a defined and delayable

response can be configured for SIMOCODE pro. In this case,

for example, the motor can be shut down independent of the

overload protection. The blocking protection is only enabled

after the configured class time has elapsed and avoids

unnecessarily high thermal and mechanical loads as well as

wear of the motor.

Thermistor motor protection

3)

Monitoring the power factor

• This protection function is based on direct temperature

measurements by means of temperature sensors in the stator

windings or in the enclosure of the motor. These protective

functions should be used, in particular, in motors with high

operating frequencies, heavy-duty starting, intermittent and/or

braking operation, but also in the case of speeds lower than

the rated speed. SIMOCODE pro supports connection and

evaluation of several PTC sensors connected in series on the

basic unit. In addition, the sensor measuring circuit can be

monitored for short-circuits and wire breakages. If the

temperature of the motor increases beyond a defined limit or

if there is a fault in the sensor measuring circuit, a defined

response can be configured.

• Especially in the low-end performance range of a motor, the

power factor varies more than the motor current or active

power. Monitoring of the power factor is therefore particularly

useful for distinguishing between motor idling and fault events

such as a tear in a drive belt or a crack in a drive shaft.

• SIMOCODE pro supports two-stage monitoring of power

factor undershoot for freely selectable limit values. The

response of SIMOCODE pro can be freely configured and

delayed if it reaches an alarm or tripping threshold.

1)4)

Temperature monitoring

• The temperature can be monitored, for example, in the motor

windings or at the bearings through up to three resistance

sensors connected to the temperature module.

Ground-fault monitoring (internally) with a current measuring

module or current/voltage measuring module

• SIMOCODE pro supports two-stage monitoring of overheating

for freely selectable limit values. The response of

SIMOCODE pro can be freely configured and delayed if it

reaches an alarm or tripping threshold. Temperature

monitoring is always performed with reference to the highest

temperature of all sensor measuring circuits used.

• SIMOCODE pro acquires and monitors all three phase

currents. With vector addition of the phase currents, the motor

feeder can be monitored for possible fault currents or ground

faults with the help of internal calculations. Internal earth fault

monitoring is only available for motors with three-phase

connections in directly grounded networks or in networks

grounded with low impedance. The response of

SIMOCODE pro when a ground fault is detected can be

parameterized and delayed as required.

Ground-fault monitoring (external) with summation current

1)2)

transformer

• External ground-fault monitoring is normally implemented for

networks that are grounded with high impedance. Using an

additional summation current transformer (3UL2 20.-.A), even

extremely low ground-fault currents can be measured. The

response of SIMOCODE pro when a ground fault is detected

can be parameterized and delayed as required. Fault current

measurement is performed for each summation current

transformer for the following fault currents: 0.3/0.5/1 A

1) Using basic unit 2.

2) An additional ground-fault module with a 3UL22 summation current

transformer is required.

3) Using basic unit 2 with current/voltage measuring module.

4) An additional temperature module is required.

SIMOCODE 3UF Motor Management and Control Devices

SIMOCODE pro 3UF7

motor management and control devices

Monitoring additional process variables over analog inputs

Regardless of whether a control command is sent to SIMOCODE

pro via PROFIBUS DP using the operator module or via the

buttons connected to the binary SIMOCODE pro inputs,

SIMOCODE pro can execute these control commands

simultaneously or in accordance with the enabled commands

defined during configuration.

1)2)

(0/4 ... 20 mA)

• The analog module enables SIMOCODE pro to measure

additional process variables and monitor them. A pump can,

for example, be protected against dry running in this manner

with level monitoring or the degree of pollution of a filter can

be measured using a differential pressure transducer. When a

specified level is undershot, the pump can be deactivated

and when a specified differential pressure is overshot, the filter

can be cleaned.

• SIMOCODE pro supports two-step monitoring of the corre-

sponding process variable for freely selectable upper and

lower current limit values. The response of SIMOCODE pro

can be freely configured and delayed if it reaches an alarm or

tripping threshold.

These predefined control functions can also be flexibly adapted

to each customized configuration of a motor feeder by means of

freely configurable logic modules (truth tables, counters, timers,

edge evaluation etc.).

In addition, special standard functions are stored in

SIMOCODE pro which can also be used to extend the protection

and control functions, e.g.:

1)

• Power failure monitoring for automatic, time-staggered

restart of motors following a network failure e.g. with the help

of a separate voltage relay (voltage controller).

3)

Phase sequence detection

• By detecting the phase sequence, SIMOCODE pro is able to

make a statement about the direction of rotation of a motor. If

the direction is incorrect, this can be reported or it can result

in immediate shutdown of the affected motor.

• Fault signaling modules for external faults with or without

manual or automatic acknowledgement for generating internal

messages or for tripping SIMOCODE pro in response to freely

definable events (e.g. overspeed monitor has been

activated). Designations/names can also be assigned to the

external faults which are stored in the device and which are

therefore also available to the I&C system.

Monitoring of operating hours, downtime and number of starts

• In order to prevent plant downtime caused by motor failure

due to excessive motor operating times (wear) or excessive

motor downtimes, SIMOCODE pro can monitor the operating

hours and downtime of a motor. When an adjustable limit value

is violated, a message or alarm can be generated which can

indicate that the corresponding motor must be serviced or

replaced. After the motor has been replaced, the operating

hours and downtimes can be reset, for example.

• To avoid excessive thermal loads and early wear of the motor,

it is possible to limit the number of motor startups for a

specifiable period. Alarms can indicate that only a small

number of possible starts remain.

• Emergency start function and reset of the thermal memory of

SIMOCODE pro after tripping, i.e. immediate restart is

possible (important, for example, for pumps used to

extinguish fires).

• Test function for the load feeder circuit when the main control

switch is open to test the control circuit while the main circuit

is de-energized.

Detailed operational, service and diagnostics data

SIMOCODE pro provides a variety of operating, service and

diagnostic data, such as:

Flexible motor control implemented with software

Operating data

Many typical motor control functions have been predefined in

SIMOCODE pro and are available for use:

• The switching state of the motor (On, Off, clockwise, counter-

clockwise, fast, slow) is derived from the current flow in the

main circuit, so checkbacks are not required through auxiliary

contacts from circuit-breakers and contactors

• Current in phase 1, 2, 3 and maximum current in % of the set

current

• Direct-on-line and reversing starters

1)

• Wye-delta starters (also with direction reversal)

• Two speeds, motors with separate windings (pole-changing

1)2)

• Current values of the analog signals

• Time until tripping in sec.

It is also monitored whether the current checkback of the motor

feeder corresponds with the control command. If not,

SIMOCODE pro opens the motor contactor and generates an

alarm indication.

• Temperature rise for motor model in %

• Remaining cooling time of the motor in sec. etc.

Service data

• Motor operating hours (can be reset)

• Motor stop times (can be reset)

• Number of motor starts (can be reset)

• Number of remaining permissible motor starts

• Number of overload trips (can be reset)

• Internal comments, stored in the device for each feeder,

e.g. notes for maintenance events etc.

Depending on the application, motor control can be switched

over or carried out simultaneously from several control stations,

e.g.:

• From the I&C system through PROFIBUS DP

• From a PC/PG through PROFIBUS DP

• From the control cabinet door through the operator panel

• From a PC/PG on the system interface through

SIMOCODE pro

• From a local control station on the motor. In this case, the

buttons, switches and indicator lights are connected to the

inputs and outputs of SIMOCODE pro.

1) Using basic unit 2.

2) An additional analog module is required.

3) Using basic unit 2 with current/voltage measuring module.

4) An additional temperature module is required.

Diagnostic data

Autonomous operation

• Numerous detailed early warning and fault messages (can

also be used for further processing in the device or I&C

system)

• Internal device fault logging with time stamp

• Value of the previous tripping current

• Checkback error (e.g. no current flow in the main circuit

following ON control command) etc.

An essential feature of SIMOCODE pro is independent

execution of all protection and control functions even if

communication with the I&C system breaks down. If the bus or

automation system fails, the full functionality of the feeder is

ensured or a pre-defined response can be initiated, e.g. the

feeder can be shut down in a controlled manner or certain

configured control mechanisms can be performed (e.g. the

direction of rotation can be reversed).

Integration

General

OM SIMOCODE pro object manager

(as part of SIMOCODE ES Professional)

In addition to device function and hardware design, a great deal

of emphasis is placed on the case of communication-capable

controlgear on the user-friendliness of the configuration software

and the ability of the system to be integrated easily into various

different system configurations and process automation sys-

tems. For this reason, the SIMOCODE pro system provides suit-

able software tools for consistent, time-saving parameterization,

configuration and diagnostics:

• SIMOCODE ES for totally integrated startup and service

• OM SIMOCODE pro object manager for total integration into

SIMATIC S7

• PCS 7 function block library SIMOCODE pro for total

integration into PCS 7

The OM SIMOCODE pro object manager is a standard

component of SIMOCODE ES Professional. In contrast to a

conventional GSD file, it enables SIMOCODE ES to be

integrated into STEP 7 for convenient device parameterization.

By installing SIMOCODE ES Professional and

OM SIMOCODE pro on a PC/PG, which is used to configure the

hardware of the SIMATIC S7, SIMOCODE ES Professional can

be called directly from the hardware configuration. This allows

easy and consistent S7 configuration.

PCS 7 function block library for SIMOCODE pro

The SIMOCODE pro PCS 7 library can be used for simple and

easy integration of SIMOCODE pro into the SIMATIC PCS 7 V6

process control system. The SIMOCODE pro PCS 7 function

block library contains the diagnostic and driver blocks

corresponding with the diagnostic and driver concept of

SIMATIC PCS 7 as well as the elements (symbols and faceplate)

required for operator control and process monitoring. The

application is integrated by graphic interconnection using the

CFC Editor.

SIMOCODE ES

The parameterization software for SIMOCODE pro can be run on

a PC/PG under Windows 2000 or Windows XP. It is available in

two functionally graded versions:

• SIMOCODE ES Smart, for direct connection to

SIMOCODE pro via the system interface on the device

(point-to-point)

The technological and signal processing functions of the

SIMOCODE pro PCS 7 function block library are based on the

SIMATIC PCS 7 standard libraries (driver blocks, technological

blocks) and are optimally tailored to SIMOCODE pro. Users who

previously configured motor feeder circuits using conventional

technology by means of signal blocks and motor or valve blocks,

can now easily switch to the SIMOCODE pro PCS 7 function

block library.

• SIMOCODE ES Professional, for connection to one or

several devices over PROFIBUS DP or point-to-point through

the system interface

With SIMOCODE ES, the SIMOCODE motor management sys-

tem provides a user-friendly and clear-cut user interface with

which to configure, operate, monitor and test SIMOCODE pro in

the field or from a central location. By displaying all operating,

service and diagnostics data, SIMOCODE ES supplies impor-

tant information on whether maintenance work is required or, in

the event of a fault, helps to prevent faults or to localize and rec-

tify them once they have occurred.

The SIMOCODE pro PCS 7 function block library supplied on

CD-ROM allows the user to run the required engineering

software on the engineering station (single license) including the

runtime software for executing the AS blocks in an automation

system (single license). If the AS blocks are to be used in

additional automation systems, the corresponding number of

runtime licenses are required which are supplied without a data

carrier.

Unnecessary plant downtimes can be prevented by changing

parameters online (even during operation). The flexible printing

function integrated into SIMOCODE ES allows comprehensive

documentation of all parameters or partial documentation of

selected or changed parameters.

System manual for SIMOCODE pro

• SIMOCODE ES Graphic is an optional software package for

SIMOCODE ES Smart or SIMOCODE ES Professional. It

expands the user interface with a graphical editor and

supports extremely user-friendly parameterization with Drag &

Drop. Inputs and outputs of function blocks can be graphically

linked and parameters can be set. The configured functions

can be described in greater detail using comments and the

device parameterization can be documented graphically –

this speeds up start-up and simplifies the plant

The SIMOCODE pro system manual describes the motor

management system and its functions in detail. It contains

information about configuration and commissioning as well as

servicing and maintenance. A typical example of a reversing

starter application is used to teach the user quickly and

practically how to use the system. In addition to help on how to

identify and rectify faults in the event of a malfunction, the

manual also contains special information for servicing and

maintenance.

documentation.

Furthermore, the manual contains schematics, dimensional

drawings and technical specifications of the system

components as configuring aids.

Note:

Installation of SIMOCODE ES Graphic requires at least one

installed version of SIMOCODE ES Smart 2004+SP1 or

SIMOCODE ES Professional+SP1 (from April 2005) on the

PC/PG.

motor protection and control devices

Function

Protective and monitoring functions

Ground-fault monitoring

For the protection of loads against impermissible high

temperature rises

Two qualitatively different ground-fault monitoring functions are

offered:

• "Internal" ground-fault monitoring by means of calculation

The internal ground-fault monitoring is only suitable for motors

with 3-wire connection and for networks that are grounded

directly or with a low impedance. In this case, the ground-fault

current is calculated by vector addition of the phase currents

of the SIMOCODE-DP current transformer. An additional

summation current transformer is not necessary. In fault-free

systems, the vectorial summation current of the three phases

is zero; if this is not the case, a ground-fault is signaled.

Ground-fault currents that are more than 30 % of the operating

Types of overload protection:

• Current-sensitive, electronic overload protection with

adjustable tripping characteristics (class times)

SIMOCODE-DP protects three-phase or AC motors from

overloading according to the requirements of IEC 60947-4-1.

The class (trip class) indicates the maximum tripping time

during which SIMOCODE-DP must trip at 7.2 times the

operational current from cold. The trip class can be set in six

stages from Class 5 to Class 30. The break time can therefore

be extremely finely adjusted to the load torque of the motor –

to optimize utilization of the motor (see also the section

Characteristic Curves).

current I are detected.

e

• "Internal" ground-fault monitoring by means of measurement

The external ground-fault detection is normally used in supply

systems that have a high impedance ground. An additional

summation current transformer (3UL2 20.-.A) is required for

this method that is also suitable for extremely low ground-fault

currents. Detected fault current, depending on the summation

current transformer: 0.3/0.5/1 A.

• Phase failure/unbalance monitoring

A signal is output for a phase unbalance greater than 40 %.

The tripping times of the overload characteristic are reduced,

because the heat generated in the motor rises under

unbalanced conditions (additional eddy-current losses).

• Thermistor motor protection

Temperature-dependent motor protection is based on direct

temperature measurements in the motor. These protective

functions should be used, in particular, in motors with high

operating frequencies, heavy-duty starting, intermittent and/or

braking operation, but also in the case of a blocked air supply

or speeds lower than the rated speed. For this reason, a wide

range of different temperature sensors are available that are

installed in the stator winding or in the motor enclosure.

SIMOCODE-DP can evaluate the following sensor types:

- Binary PTC sensors whose resistance rises sharply when the

temperature limit is reached

Current limit monitoring I>, I<

Current limit monitoring is not used for motor protection, but for

process monitoring.

It is used to detect developing irregularities in the plant early,

e.g. motor bearings becoming tight (consequence: upper limit

responds) or the belt coupling to the drive machine tears

(consequence: lower limit responds).

Comprehensive motor and plant diagnostics

- Analog temperature sensors, such as NTC, KTY83/84, which

have an almost linear characteristic curve and can therefore

be set to any warning or switch-off temperatures

SIMOCODE-DP provides a variety of measuring, operating and

diagnostics data concerning the load feeder:

• Up-to-date information during operation, e.g.:

- The currently flowing phase current in %

- The switching state of the motor (On, Off, clockwise,

counterclockwise, fast, slow) derived from the current flow

- Manual/automatic mode

EEx e type of protection

The SIMOCODE-DP system is in compliance with the regulations

for overload protection of explosion-protected motors of the

EEx e "Increased safety" type of protection according to

- Test mode

- Cooling time activated after an overload tripping operation

• EN 50019

• Detection of incipient faults, e.g.:

- Overload warning

• EN 60079-7, IEC 60079-7

• EN 60079-14 (potentially explosive areas)

• EN 50281 (areas with combustible dust)

• ATEX/PTB test regulations

- Current limit overshoot

- Phase unbalance

- Thermistor warning

• Rapid diagnostics in the event of an alarm, e.g.:

- Overload

In the case of SIMOCODE-DP units with 24 V DC control infeed,

isolation by battery or safety transformer according to

EN 61558-2-6 must be assured.

- Thermistor motor protection

- Rotor locking

EC type test certificate: PTB01 ATEX 3219

Test report: PTB EX 01-30013

- Current limit overshoot

- Checkback error (e.g. no current following On command)

• Preventive maintenance by means of statistical data, e.g.:

- Number of starts

- Number of overload trips

- Tripping currents

- Operating hours

Rotor locking protection

When the motor current rises above a rotor locking threshold that

can be set, SIMOCODE-DP does not trip according to the

overload characteristic, but switches off immediately instead.

The prevention of unnecessary thermal loads prevents

premature aging of the motor. The rotor locking protection is not

active for start-up monitoring until the class time has elapsed,

e.g. for Class 10 after 10 seconds.

Integrated standard programs for motor control

In SIMOCODE-DP, a number of different opportunities for

controlling the motor has been predefined and can be called up

in the form of control functions:

• Overload relay

• Direct-on-line starter

• Reversing starter

• Wye-delta starter

SIMOCODE-DP 3UF5

motor protection and control devices

• Two speeds, Dahlander winding

• Two speeds, separate winding

• Valve

• Actuator

• Soft starter (3RW)

Furthermore, special standard function blocks are stored in

SIMOCODE-DP:

• Automatic, time-discrete reactivation of motors following

mains failure

The prerequisites are as follows:

- Failure of the three-phase supply must take place through a

separate voltage relay

These control programs already include all the software

interlocks and logic operations required for operation of the

required motor functions.

- The supply voltage of SIMOCODE-DP must not be

interrupted

• Different error signaling modules with and without

acknowledgement

These allow SIMOCODE-DP to trip as a result of external

events (e.g. overspeed monitor has tripped)

It is also monitored whether the current checkback of the motor

feeder corresponds with the control command. If not,

SIMOCODE-DP opens the motor contactor and generates an

alarm indication.

• The emergency start function

The motor can be controlled by any equipment depending on

the application:

• From the process control system or the PC through

PROFIBUS DP

• From the control cabinet door through the operator panel

• From a local control point on the motor, whereby the

pushbuttons/switches are wired to the SIMOCODE-DP inputs

This resets the thermal memory of SIMOCODE-DP

immediately after overload tripping, i.e. immediate restarting

is possible (important, for example, for a fire-extinguisher

pump)

• The test function for the load feeder

This can be activated by switching off the main switch Q1 (see

the section Schematics) and allows the control circuit to be

checked with the motor branch at zero current.

The standard control functions can also be adapted to each

customized variant of a motor feeder by means of freely-

parameterizable elements, such as timers, counters, logic

operations (AND, OR, NOR, etc.).

■

Integration

The SIMOCODE-DP modular system offers a wide range of

software packages for system-wide and time-saving

configuration and diagnostics:

• PC software Win-SIMOCODE-DP for start-up and service

• Object manager OM-SIMOCODE for "totally integrated" in

SIMATIC S7

• Using the OM-SIMOCODE-DP object manager

i.e. SIMOCODE-DP becomes an integral component of

STEP 7; the OM-SIMOCODE-DP object manager should, in

this case, always be combined with the start-up and service

software Win-SIMOCODE-DP/Professional

Both software packages must be installed on the PG/PC on

which the hardware configuration of SIMATIC S7 is performed.

This ensures that Win-SIMOCODE-DP/Professional can be

called up directly from HW-Config.

• Function block FB-SIMOCODE for "totally integrated" in PCS7

PC software Win-SIMOCODE-DP for start-up and service

Parameter sets created with Win-SIMOCODE-DP/Professional

are loaded into the STEP 7 data storage by means of OM and

automatically transferred to SIMOCODE-DP during start-up.

Standard PC software Win-SIMOCODE-DP for start-up and

service. It offers a user-friendly and convenient user-interface

for:

• Parameterization

• Display and diagnostics

• Test functions

Functions specific to SIMATIC S7, such as diagnostic and

hardware interrupts are supported, which means easier S7-wide

configuration as well as optimal performance in the transfer of

diagnostic data.

• Motor control

Win-SIMOCODE-DP is available in two versions:

• Win-SIMOCODE-DP/Smart

for direct connection to SIMOCODE-DP through the system

interface on the device

• Win-SIMOCODE-DP/Professional

for direct connection to SIMOCODE-DP over PROFIBUS or

directly through the system interface on the device

Function block FB-SIMOCODE for "totally integrated" in

PCS7

With PCS7-FB SIMOCODE-DP it is easy and convenient to

integrate SIMOCODE-DP into the SIMATIC PCS 7 process

control system. PCS7-FB SIMOCODE-DP contains the

diagnostic and driver blocks corresponding with the diagnostic

and driver concept of SIMATIC PCS 7 as well as the elements

(symbols and faceplate) required for operator control and

process monitoring. The application is integrated by graphic

interconnection using the CFC Editor. The technological and

signal processing functions of the PCS7-FB SIMOCODE-DP are

based on the SIMATIC PCS 7 standard libraries (driver blocks,

technological blocks) and are optimally tailored to SIMOCODE-

DP. Users who previously configured motor feeder circuits using

conventional technology by means of signal blocks and motor or

valve blocks, can now easily switch to PCS7-FB SIMOCODE-DP.

The PCS7-FB SIMOCODE-DP supplied on CD-ROM allows the

user to run the required engineering software on one

OM-SIMOCODE object manager for "totally integrated" in

SIMOCODE-DP can be integrated into SIMATIC S7 in two

different ways:

i.e. integration in SIMATIC S7 is identical to integration in any

other DP standard master system

software for executing the AS blocks in an automation system

(single license).

3UF18 current transformers

for overload protection

■

Overview

The 3UF1 8 current transformers are protection transformers and

are used for actuating overload relays. Protection transformers

are designed to ensure proportional current transfer up to a

multiple of the primary rated current. The 3UF18 current

transformers convert the maximum current of the corresponding

operating range into the standard signal 1 A secondary.

LOGO! Logic Modules

General data

■

Overview

■

Design

The LOGO! modular design is available in different variants for

different supply voltages (12 V DC, 24 V DC, 24 V AC,

115/230 V DC, 115/230 V AC):

• Basic variants

• Low-cost pure variants without operator control and display

panels

The LOGO! variants have the following distinguishing

characteristics:

• R: Relay output

• C: Clock/time switch

• o: Without display

LOGO! is simple:

• Warning and switching off in one unit; no other tools are

required

• Non-volatile storage of control program and setpoints

(e.g. times) in integrated EEPROM

• The compact, user-friendly, and low-cost solution for simple

control tasks

LOGO! is space-saving:

• e.g. LOGO! 230RC: 72 x 90 x 55 mm (W x H x D)

• Compact, user-friendly, can be used universally without

accessories

• "All in one": the display and operator panel are integrated

• 36 different functions can be linked at a press of a button or

with PC software; up to 130 times in total

• Functions can be changed simply using buttons;

no complicated rewiring

• Fitted mounting in the distribution box (same mounting

dimensions as the ground-fault circuit interrupter)

LOGO! offers maximum flexibility and is universal:

• Expandability:

Depending on the application, additional expansion modules

can be connected

LOGO! is communication-capable:

Catalog ST 70

• Optional communication modules support interfacing to

AS-Interface and instabus EIB networks

Information on LOGO! can also be found in the catalog ST 70:

http://www.siemens.com/automation/

simatic/ftp/st70/html_00/st70k1ad.pdf

■

Function

LOGO! is simple:

• 36 functions:

Integrated basic functions (e.g. AND, OR) and special

functions (e.g. timers, counters, latching relays, PI controllers)

of the electronics

• Program generation simply by combining stored functions at

the press of a key or PC software

• Easy-to-use and simple duplication of the control program

with an optional program module

LOGO! offers maximum flexibility and is universal:

• Easy modification by reconnecting the functions at a press of

a key; no need for time-consuming rewiring

• Optional operation from the PC:

For creating, simulating, online testing and archiving the

control program on the PC, including documentation facility

Operation 1

Operation 1:

Start contact B./A2 is opened when supply voltage A./A2 is applied.

A./A2

The supply voltage is applied to A./A2 and there is no control signal on

B./A2. This starts the *D timing. The idling time (overtravel time) is

B./A2

started by applying a control signal to B./A2. When the set time I

Idling

(30 to 600 s) has elapsed, the output relays (17/16 and 17/28) are reset.

If the control signal on B./A2 is switched off (minimum OFF period

270 ms), a new timing is started.

Comments:

Observe response time (dead time) of 400 ms on energizing supply

If the control signal B./A2 is already present when the supply voltage

control signal B./A2 is switched off.

Operation 2

Operation 3:

Start contact B./A2 closes while star time is running.

Operation 4:

17/16

Start contact B./A2 opens while delta time is running and is applied

again.

If the control signal on B./A2 is applied and switched off again during

the delta time, although the idling time has not yet elapsed, the idling

time (overtravel time) is reset to zero. If the control signal is re-applied to

B./A2, the idling time is restarted.

Operation 3

Application example based on standard operation (operation 1)

For example, use of 3RP15 60 for compressor control

A./A2

Frequent starting of compressors strains the network, the machine, and

the increased costs for the operator. The new timing relay prevents

frequent starting at times when there is high demand for compressed

air. A special control circuit prevents the compressor from being

switched off immediately when the required air pressure in the tank has

been reached. Instead, the valve in the intake tube is closed and the

compressor runs in "Idling" mode for a specific time which can be set

from 30 to 600 s.

B./A2

17/18

Y

17/28

17/16

If the pressure falls within this time, the motor does not have to be

restarted again, but can return to nominal load operation from no-load

operation.

NSB00893

t

50 ms

Y

If the pressure does not fall within this idling time, the motor is switched

off.

t _Idling

the pressure switch controls the timing via B./A2.

Operation 4

The supply voltage is applied to A./A2 and the start contact B./A2 is

open, i.e. there is no control signal on B./A2 when the supply voltage is

applied. The pressure switch signals "too little pressure in system" and

starts the timing by way of terminal B./A2. The compressor is started,

enters *D operation, and fills the pressure tank.

A./A2

B./A2

When the pressure switch signals "sufficient pressure", the control signal

B./A2 is applied, the idling time (overtravel time) is started, and the

compressor enters no-load operation for the set period of time between

30 to 600 s. The compressor is then switched off. The compressor is

only restarted if the pressure switch responds again (low pressure).

Overview

■

Function

• Changes to the time setting ranges and the functions must be

carried out in the de-energized state

• Start input B1 or B3 must only be triggered when the supply

voltage is applied

Standards

The timing relays comply with:

• EN 60721-3-3 "Environmental conditions"

• EN 61812-1/DIN VDE 0435 Part 2021 "Solid-state relays,

timing relays"

• EN 61000-6-2 and EN 61000-6-4 "Electromagnetic

compatibility"

• EN 60947-5-1; (VDE 0660 Part 200) "Low-voltage controlgear,

switchgear and systems – Electromechanical controlgear"

• The same potential must be applied to A1 and B1 or A3 and

B3. With two-voltage version, only one voltage range must be

connected

• The activation of loads parallel to the start input is not

permissible when using AC (see diagrams)

• Surge suppression is integrated in the timing relay. This

prevents the generation of voltage peaks on the supply

voltage when the relay is switched on and off. No additional

damping measures are necessary

3RP15 timing relays, width 22.5 mm

• 3RP15 05-.R must not be operated next to heat sources

■

Overview

■

Function

• Changes to the time setting ranges and the functions must be

carried out in the de-energized state

• Start input B1 or B3 must only be triggered when the supply

voltage is applied

Standards

The timing relays comply with:

• EN 60721-3-3 "Environmental conditions"

• EN 61812-1/DIN VDE 0435 Part 2021 "Solid-state relays,

timing relays"

• EN 61000-6-2 and EN 61000-6-4 "Electromagnetic

compatibility"

• EN 60947-5-1; (VDE 0660 Part 200) "Low-voltage controlgear,

switchgear and systems – Electromechanical controlgear"

• EN 61140 "Safe electrical isolation"

• The same potential must be applied to A1 and B1 or A3 and

B3. With two-voltage version, only one voltage range must be

connected

• The activation of loads parallel to the start input is not

permissible when using AC (see diagrams)

• Surge suppression is integrated in the timing relay. This

prevents the generation of voltage peaks on the supply

voltage when the relay is switched on and off. No additional

damping measures are necessary

Overview

Solid-state line monitoring relays provide maximum protection

for mobile machines and plants or for unstable networks.

Network and voltage faults can be detected early and rectified

before far greater damage ensues.

Depending on the version, the relays monitor phase sequence,

phase failure with and without N conductor monitoring, phase

unbalance, undervoltage or overvoltage. With the 3UG46 17

or 3UG46 18 relay, a wrong direction of rotation can also be

corrected automatically.

■

Function

3UG45 11 monitoring relays

3UG45 12 monitoring relays

The 3UG45 11 phase sequenced relay monitors the phase

sequence in a three-phase network. No adjustments are

required for operation. The device has an internal power supply

and works using the closed-circuit principle. If the phase

sequence at the terminals L1-L2-L3 is correct, the output relay

picks up after the delay time has elapsed and the LED is lit. If the

phase sequence is wrong, the output relays remain in their rest

position.

The 3UG45 12 line monitoring relay monitors three-phase

networks with regard to phase sequence, phase failure and

phase unbalance of 10 %. Thanks to a special measuring

method, a phase failure is reliably detected in spite of the wide

voltage range from 160 to 690 V AC and feedback through the

load of up to 90 %. The device has an internal power supply and

works using the closed-circuit principle. No adjustments are

required. When the mains supply is switched on, the green LED

is lit. If the phase sequence at the terminals L1-L2-L3 is correct,

the output relay picks up. If the phase sequence is wrong, the

red LED flashes and the output relay remains in its rest position.

If a phase fails, the red LED is permanently lit and the output

relay drops.

Note:

When one phase fails, connected loads (motor windings, lamps,

transformers, coils, etc.) create a feedback voltage at the

terminal of the failed phase due to the network coupling.

Because the 3UG45 11 relays are not resistant to voltage

feedback, such a phase failure is not detected. Should this be

required, then the 3UG45 12 monitoring relay must be used.

Note:

The red LED is a fault diagnostic indicator and does not show the

current relay status. The 3UG45 12 monitoring relay is suitable

for line frequencies of 50/60 Hz.

3UG46 17/3UG46 18 monitoring relays

The 3UG46 15/3UG46 16 line monitoring relay has a wide

voltage range and an internal power supply. The device is

equipped with a display and is parameterized using three

buttons. The 3UG46 15 device monitors three-phase networks

with regard to phase failure, undervoltage, overvoltage and

phase sequence. The 3UG46 16 monitoring relay monitors the

neutral conductor as well. The hysteresis is adjustable from 1 to

20 V. In addition the device has two separately adjustable delay

times for overvoltage and undervoltage from 0 to 20 s in each

case. If the direction is incorrect, the device switches off

immediately. Thanks to a special measuring method, a phase

failure is reliably detected in spite of the wide voltage range from

160 to 690 V AC and feedback through the load of up to 80 %.

The 3UG46 17/ 3UG46 18 line monitoring relay has an internal

power supply and can automatically correct a wrong direction of

rotation. Thanks to a special measuring method, a phase failure

is reliably detected in spite of the wide voltage range from 160

to 690 V AC and feedback through the load of up to 80 %. The

device is equipped with a display and is parameterized using

three buttons. The 3UG46 17 line monitoring relay monitors

three-phase networks with regard to phase sequence, phase

failure, phase unbalance, undervoltage and overvoltage. The

3UG46 18 monitoring relay monitors the neutral conductor as

well. The hysteresis is adjustable from 1 to 20 V. In addition the

device has delay times from 0 to 20 s in each case. The times

respond to overvoltage, undervoltage, phase failure and phase

unbalance. The 3UG46 17/3UG46 18 monitoring relay can be

operated on the basis of either the open-circuit or closed-circuit

principle and with manual or auto RESET.

The 3UG46 15/3UG46 16 monitoring relay can be operated on

the basis of either the open-circuit or closed-circuit principle and

with manual or auto RESET.

The one changeover contact is used for warning or switching off

in the event of line faults (voltage, unbalance), the other

responds only to a wrong phase sequence. In conjunction with

a contactor reversing assembly it is thus possible to change the

direction automatically.

Monitoring Relays

3UG Monitoring Relays for Electrical and Additional Measurements

Power factor monitoring

■

Overview

The 3UG30 14 power factor monitoring device enables the load

monitoring of motors.

Function

The 3UG30 14 monitoring relay is used for monitoring the load of

motors by measuring the phase angle between voltage and

current, i.e. the power factor. The output relays respond as long

as the power factor lies between the upper and lower thresholds.

These are set separately on the front using two potentiometers.

Note:

Power factor monitoring relays are connected in series after the

motor contactor to ensure that the delay time for bridging start-

up elapses after switch-on. For this reason, the output relay must

not be connected in series with the supply voltage of the motor

contactor, otherwise it would not be possible to switch on the

load feeder. The minimum current must be at least 0.2 A.

When the value of the power factor lies outside this range, the

corresponding output relay will drop after a delay time T1, that

can be set on the front, has elapsed. A fixed hysteresis prevents

the output relay from continuously switching on and off when the

measured value is close to the threshold.

Monitoring Relays

3UG Monitoring Relays for Electrical and Additional Measurements

Insulation monitoring

for ungrounded AC networks

■

Overview

Relay for monitoring the insulation resistance between the

ungrounded single or three-phase AC supply and a protective

ground conductor:

• Measuring principle with superimposed DC voltage

• Two selectable measuring ranges of 1 ... 110 kW

• Stepless setting within the measuring range

• Selectable:

- Auto reset function with fixed hysteresis or

- Storage of the tripping operation

• Test function with test button and terminal connections on the

front

• Switching output: 1 CO contact

• Insulation fault indication with a red LED

• Supply voltage indication with a green LED

• Electro-magnetically compatible according to EN 50081 and

EN 61000-6-2.

Function

The monitoring relay measures the insulation resistance

between the ungrounded AC supply and an associated

protective ground conductor.

Note:

The monitoring relay is designed for AC supply systems.

Series-connected rectifiers must be galvanically isolated from

the measuring relay that is to be monitored.

A superposed DC measuring voltage is used to perform the

measurement.

The monitoring relay is divided into two ranges for an insulation

resistance range from 1 to 100 kW. A range switch on the front

can be used to switch over between a 1 to 11 kW range and a

10 to 110 kW range. Within the selected range, the monitoring

relay can be steplessly adapted to the respective insulation

conditions.

If the insulation resistance exceeds 1.6 times (corresponding to

60 % hysteresis) the set threshold, the output relay will return to

the rest position.

Test

_Test= > approx. 300 ms

Test functions

The "Test" button on the front can be used to simulate a ground

fault. If the "Test" button is pressed for at least 300 ms, the output

relay is energized and the fault LED lights up. An external test

button can be connected to terminal Y1. The function is

activated by closing (> 300 ms).

Fault storage and RESET

If terminals Y1 and Y2 are jumpered, the monitoring relay is set

to fault storage mode. If the set insulation resistance is under-

shot, the output relay is excited and remains tripped even after

the insulation resistance rises above 1.6 times the set value

again. Fault storage can be reset by briefly pressing the RESET

button, briefly jumpering (< 300 ms) the Y1 and PE/ground

terminals or by switching off and on the supply voltage.

Insulation monitoring

for ungrounded DC networks

■

Overview

Relay for monitoring the insulation resistance between

ungrounded pure DC networks and a protective-ground

conductor:

• Front selector switch for open-circuit and closed-circuit

principle for the output relay

• Test function with test buttons on the front for L+ and L-

and over terminal connections

• Measuring principle for differential current measurement

• Response threshold can be set continuously from

• Switching output: 1 CO contact

• Insulation fault indicator for L+ and L- through two red LEDs

• Supply voltage indication with a green LED

• Electro-magnetically compatible according to EN 50081 and

EN 61000-6-2

10 to 110 kW

• Selectable

- Auto reset function with hysteresis or

- Storage of the tripping operation

■

Function

The monitoring relay measures the insulation voltage between

the positive and negative supply voltage in an ungrounded DC

network and a corresponding protective conductor.

Open/closed-circuit principle selector switch

The function principle of the output relay can be adjusted by

means of a selector switch on the front panel.

The measurement is based on the DC residual current

measurement principle. The response value can be adjusted

steplessly in the range from 10 to 110 kW and thus can be

adapted to the corresponding conditions. If the insulation

resistance falls below the set response value, the output relay

triggers (depending on the setting of the open/closed-circuit

principle selector switch) and a fault LED lights up.

If the relay is to respond in the event of a fault (contact symbol

open), the open-circuit principle must be selected. If the relay

however is to trigger in the event of a fault (contact symbol

closed), the closed-circuit principle must be selected.

Note:

A ground fault is evaluated separately for L+ and L- and

indicated by means of a corresponding LED.

The position of the selector switch has no effect upon the fault

LEDs. The LEDs always light up if the insulation resistance on L+

or L– falls below the set value.

Note:

Due to the measurement principle, a symmetrical ground fault on

terminals L+ and L- cannot be evaluated.

Fault storage and RESET

If terminals Y2 and Y3 are linked, the monitoring relay is set to

fault storage mode.

If the insulation resistance falls below the set value, the output

relay triggers (depending on the setting of the open/closed

circuit selector switch), and stays in this state even if the

insulation resistance rises again above the hysteresis value

(typical: 2 times the set value). This fault storage can be deleted

by pressing and releasing the L+ RESET button, opening the

Y2-Y3 connection or by switching off the supply voltage.

Monitoring Relays

3UG Monitoring Relays for Electrical and Additional Measurements

Level monitoring

■

Overview

The 3UG35 01 level monitoring relay is used together with the

2- or 3-pole sensors to monitor the levels of conductive liquids.

Function

The principle of operation is based on measuring the electrical

resistance of the liquid between two immersion sensors and a

reference terminal. If the measured value is lower than the

sensitivity set at the front, the output relay changes its switching

state. In order to exclude electrolytic phenomena in the liquid,

the sensors are supplied with alternating current.

Note:

It is also possible to connect other resistance sensors to the Min

and Max terminals in the range 5 to 100 kW, e.g. photoresistors,

temperature sensors, encoders based on resistance etc.

The monitoring relay can therefore also be used for other

applications apart from monitoring the levels of liquids.

Two-level control: the output relay changes its switching state as

soon as the liquid level reaches the maximum sensor, while the

minimum sensor is submerged. The relay returns to its original

switching state as soon as the minimum sensor no longer has

contact with the liquid.

Monitoring Relays

3UG Monitoring Relays for Electrical and Additional Measurements

Speed monitoring

■

Overview

The 3UG30 51 monitoring relay is used together with a sensor to

monitor drives for underspeeding.

Function

The underspeed monitoring relay operates according to the

principle of retriggerable OFF-delay. During the time (value) set

on the front panel, another pulse must arrive at input IN1 or IN2

to ensure that the output relay remains picked up. The

monitoring relay evaluates the rising edge of the signal, i.e.

a continuous signal is also recognized as a missing pulse. If the

retrigger pulse does not arrive, indicating a reduction in speed,

the output relay drops. In order to be able to start a drive, the

output relay remains picked up during the ON-delay time T, even

if the speed is still below the set value (motor starting override

time). The first pulse must come within this time.

Speed monitoring with memory (MEMORY)

When the output relay drops, this state remains stored even

when the speed reaches a permissible value again. The stored

state can be ended by a control signal at the reset terminal or by

interrupting the supply voltage for at least 200 ms.

Connection of resistance-type thermometers

2-wire measurement

When 2-wire temperature sensors are used, the resistances of

the sensor and wiring are added. The resulting systematic error

must be taken into account when the signal evaluator is

calibrated. A jumper must be clamped between terminals T2

and T3 for this purpose.

3-wire measurement

To minimize the effects of the line resistances, a three-wire circuit

is often used. Using the additional wire, two measuring circuits

can be formed of which one is used as a reference. The signal

evaluator can then automatically calculate the line resistance

and take it into account.

and the signal evaluator.

Once the temperature has reached the set threshold J1, the

output relay K1 changes its output state as soon as the set time

t has elapsed (K2 responds in the same manner to J2). The time

delay can only be adjusted with digital units (on analog units,

t = 0).

This principle assumes that the signal evaluator knows the

temperature at the clamping point (T2). For this reason, the

3RS11 temperature monitoring relay has an integral compen-

sator that determines this comparison temperature and builds it

into the result of the measurement. Therefore, the thermal

sensors and cables must be insulated.

The relays return to their original state as soon as the

temperature reaches the set hysteresis value.

The absolute temperature is calculated from the ambient

temperature of the signal evaluator and the temperature

difference measured by the thermocouple.

Temperature overshoot

Closed-circuit principle

Temperature detection is therefore possible (T1) without needing

to know the precise ambient temperature of the clamping point

at the signal evaluator (T2).

The connecting cable is only permitted to be extended using

connecting leads that are made from the same material as the

thermocouple. If a different type of conductor is used, an error

will result in the measurement.

Overview

The 3RS10/3RS11 analog temperature monitoring relays can be

used for measuring temperatures in solid, liquid and gas media.

The temperature is sensed by the sensors in the medium,

evaluated by the device and monitored for overshoot or

undershoot. When the threshold values are reached, the output

relay switches on or off depending on the setting.

Overview

The 3RS10/3RS11 temperature monitoring relays can be used

for measuring temperatures in solid, liquid and gas media. The

temperature is sensed by the sensor in the medium, evaluated

by the device and monitored for overshoot or undershoot or for

staying within an operating range (window function).

The 3RS10 40, 3RS20 40, 3RS11 40 and 3RS21 40 relays

comply with the requirements of DIN 3440 as temperature

monitors; the 3RS10 42 and 3RS11 42 relays comply with the

requirements of DIN 3440 as temperature limiters. The relays are

also an excellent alternative to temperature controls in the low-

end performance range (2 or 3-point closed-loop control).

3RN1 Thermistor Motor Protection

For PTC sensors

■

Overview

Thermistor motor protection devices are used for direct

monitoring of the motor winding temperature. For this purpose,

the motors are equipped with temperature-dependent resistors

(PTC) that are directly installed in the motor winding and abruptly

change their resistance at their limit temperature.

Design

The 3RN1 tripping units are suitable for use in any climate and

finger-safe according to EN 0106 Part 50274. They comply with:

• EN 61000-6-2 and EN 61000-6-4, "Electromagnetic

compatibility of I&C equipment in industrial process

engineering"

Use in areas subject to explosion hazard for gases

All devices are approved for Equipment Group II, Category (2)

in Area "G" (areas that contain explosive gases, vapor, spray and

air mixtures).

With PTB 01 ATEX 3218 ex II (2) G, compliance with

guideline 94/9 EG Appendix II is confirmed. The safety devices

must be selected with suitable settings for the safe operation of

motors of the "Increased safety" (EEx e) and "Flameproof

enclosure" (EEx d) degrees of protection and are accessed

outside the area subject to explosion hazard.

• EN 60947-8

The terminals of the auxiliary contacts are designated in

accordance with EN 50005.

The 3RN1 tripping units are suitable for snap-on mounting onto

35 mm standard mounting rails according to EN 50022 or for

screw-mounting using an adapter (Accessories).

PTB 01 ATEX 3218 ex II (2) G

The increased danger in areas subject to explosion hazard

demands careful analysis of the operator's guide, the safety and

commissioning instructions and the standard (EN 60079-14/

VDE 0165) for electronic equipment in areas subject to gas

explosion hazards.

Any mounting position is possible.

For devices with the "Manual RESET" function, the test function

can be activated and a trip simulated by pressing the blue

Test/RESET button for longer than 2 seconds.

If a Type A temperature sensor is connected to a Type A tripping

unit, compliance with the operating temperatures is assured (on

pick-up and reset) according to IEC 60034-11-2 (EN 60947-8).

A risk analysis must be performed for the complete plant or

machine. If this risk analysis results in a minimal potential for

danger (Safety Category 1), all 3RN1 TMS tripping units can be

implemented taking into account the safety notes. In the case of

plants or machines with a high potential risk, variants with

integrated short-circuit detection in the sensor circuit are

necessary.

The measuring circuit leads must be routed as separate control

leads. It is not permitted to use cores from the supply line of the

motor or any other main supply cables. If extreme inductive or

capacitive interference is expected as a result of power lines

routed in parallel, shielded control leads must be used.

Function

Maximum cable length for sensor circuit cables

The 3RN1 tripping units operate in accordance with the closed-

circuit principle and therefore monitor themselves for open-

circuit (except: warning output in the case of 3RN10 22).

A momentary power failure of less than 50 ms does not change

the status of the auxiliary contacts. The 3RN10 11, 3RN10 12

and 3RN10 13 units with 2 changeover contacts are also

equipped with short-circuit detection in the sensor circuit. The

unit will trip in the event of a short-circuit in the sensor circuit

(resistance in sensor circuit < 20 W).

All tripping units (except for 24 V AC/DC ) feature electrical

isolation between the control circuit and the sensor circuit.

1) A short-circuit in the sensor circuit will be detected up to this maximum

cable length.

3RN10 00 compact tripping units

The compact tripping unit is equipped with a red LED (TRIPPED)

for the tripped display and a changeover contact.

Notes:

After the unit has tripped, it is automatically reset once the

thermistors have cooled down. The root of the changeover

contact is connected to the control voltage (95 is connected to

terminal A1).

Tripping of the thermistor protection relay even in combination

with a converter must directly result in disconnection. This must

be implemented with circuitry.

Mounting and installation must only be performed by qualified

personnel who observe the applicable regulations! For

mounting, use installation manual No.: 3ZX1012-0RN10-1AA1.

This unit is particularly suitable in circuits in which the control

circuit and signaling circuit have the same potential, e.g. in local

control boxes.

The 3RN10 is not intended for installation in hazardous areas.

For installation in areas subject to explosion hazards, the 3RN10

must be enclosed in a flameproof casing.

3RN10 10, 3RN10 11, 3RN10 12, 3RN10 13 standard tripping

units

For tripping units with a 24 V AC/DC control voltage, electrical

isolation must be secured with a battery network or a safety

transformer according to DIN VDE 0551.

The standard units are equipped with two LEDs (READY and

TRIPPED) for an operating and tripped display and are available

with either 1 NO + 1 NC or with 2 CO contacts. They are available

depending on the version with automatic RESET (3RN10 10),

manual/remote RESET (3RN10 11) or manual/automatic and

remote RESET (3RN10 12 and 3RN10 13). Remote RESET can

be achieved by connecting an external pushbutton with a

normally-open function to terminals Y1 and Y2. If terminals Y1

and Y2 are bridged, tripping will be followed by an automatic

RESET.

When tripping units with Auto-RESET function are used, a reset

is performed automatically after the cooling time has expired. It

must be ensured by means of an external interlock (latching with

a separate On and Off button) that the machine to be monitored

does not start up again spontaneously.

Units with the Auto-RESET function must not be used in

applications in which the unexpected restart can lead to

personal injury or property damage.

The 3RN10 11, 3RN10 12 and 3RN10 13 units with 2 COs also

have short-circuit monitoring in the sensor circuit.

In the case of tripping units without short-circuit detection,

during commissioning or after modifications or maintenance

work (assembly, disassembly) on the equipment, the sensor

resistance must be measured using a suitable measuring

instrument. For resistances < 50 Ohm, the sensor circuit must

be checked for a short-circuit.

The 3RN10 12 and the 3RN10 13 are non-volatile. This means

that even if the control voltage fails, a preceding trip will be

latched.

In the case of the 3RN10 13 tripping unit, tripping due to a short-

circuit in the sensor circuit will be indicated by a flashing red

LED. The monostable version also indicates open-circuit in the

sensor circuit by flashing of the red LED.

If 3RN10 00 units are used to protect EEx e motors, separate

monitoring of the control voltage is recommended because there

is no Ready LED to indicate connection to the supply voltage.

If 3RN10 13-.BW01 units are used to protect EEx e motors,

separate monitoring of the control voltage is recommended

because the switching status of the auxiliary contacts does not

change if the control voltage fails (use of a bistable relay is

recommended).

3RN10 22 "Warning and disconnection" tripping units

Two sensor circuits can be connected to one 3RN10 22 tripping

unit that acts on one output relay with 1 NO contact for warning

and 1 CO for disconnection. Temperature sensors with different

rated response temperatures TNF are used to implement the

"Warning" and "Disconnection" functions. When the "Warning"

sensor circuit responds, a yellow LED is lit and when the

"Disconnection" circuit responds, a red LED is lit.

Before commissioning, the effectiveness of the protection

function must be checked.

The sensor circuits have a different reset response and

operating behavior:

• "Warning" (terminals 2T1, T2) only features automatic RESET

and uses the open-circuit principle.

• "Disconnection" (terminals 1T1, T2) can be changed from

manual RESET to automatic RESET by linking terminals Y1

and Y2. Remote RESET is implemented by connecting an

external pushbutton with a normally-open function.

Up to 6 sensor circuits can be connected to the 3RN10 62

simultaneous protection of several motors (up to 6) is an

advantage for multi-motor drives (e.g. if one motor is

overloaded, all the other motors of the drive will be shut down).

Apart from the red LED TRIPPED, which signals the switching

status of the tripping unit, an LED is assigned to each sensor

circuit which indicates the sensor circuit that has responded.

Unused sensor circuits must be short-circuited.

Design

The solid-state safety relays can be used in EMERGENCY-STOP

devices to EN 418 and in safety circuits to EN 60204-1 (11.98),

for example, for moving covers and protective doors.

Depending on the device type and the external circuit, the

maximum category that can be achieved is Category 4 of

EN 954-1 or SIL 3 according to IEC 61508.

Installation

For snap-on mounting on 35 mm standard mounting rail

according to EN 50022. Screw fixing is also possible for the

devices by means of 2 additional 3RP19 03 push-in lugs.
