Description
The configurable and programmable MACX
Features such as sensor type, connection method, measur-
ing range, measuring unit, filter, alarm signal and output
range can be configured using the IFS-CONF software and
a device-specific DTM (Device Type Manager).
MCR-EX-T-UI-UP... temperature transducer is used for the
intrinsically safe (Ex i) operation of all standard temperature
sensors (RTDs and thermocouples), voltage signals, re-
mote resistance-type sensors and potentiometers. The tem-
perature input signals are output in a linearized format at the
output. In addition to an analog current and voltage output,
the module also has a switching output. The power supply
has been designed as a wide range power supply.

8.13.2 Service mode
8.12 Monitoring function
Service mode can be selected at any time via the
IFS-OP-UNIT operator interface and the configuration soft-
ware, e.g., IFS-CONF or via DIP switch S1.
The temperature transducer is equipped with monitoring
functions for the input and output range.
Input monitoring function
If settings are changed during service mode and service
mode is then exited, the temperature transducer performs a
warm start in order to apply the newly set values. If no
changes are made, the transducer starts up in normal mea-
suring mode without a warm start. The switching output
switches according to its configuration.
The input monitoring function for line break and short circuit
refers to the sensor connected to the input. When an error is
detected, the output signal is set to the configured error
value. In the case of RTD sensors and resistance-type sen-
sors, short-circuit failures are detected resistance values <
1 Ω.
In service mode, it is also possible to simulate the output sig-
nal independently of the input signal (force). In this case, in
safety-related applications the safety function of the device
is deactivated and the initial value for the analog output sig-
nal is 2 mA, which allows subsequent devices to detect the
deviation from normal operation as a result of the measured
value being underrange.
Short circuits of thermocouples and mV sources cannot be
detected, since 0 V can be a valid signal.
On RTD sensors, resistance-type sensors and potentiome-
ters, a line break is detected when the current flow through
the sensor is faulty.
As soon as the fault has been eliminated, the temperature
transducer continues to perform its normal functions. (see
“LED status indicators” on page 22, Line faults)
During service mode, the switching output is deactivated
and remains in its idle position.
Output monitoring function
The current output can be monitored for line breaks and
maximum load. This is activated via the configuration. In
safety-related applications (SIL = ON), the output monitor-
ing is always active. The voltage output is not monitored. As
soon as the fault has been eliminated, the temperature
transducer continues to perform its normal functions. (see
“LED status indicators” on page 22, Line faults)

When a DIP switch from S1-2 ... S1-8 (ON) is
switched on, the device is switched to service
mode. The red ERR LED flashes (1.2 Hz) and a
diagnostic I/O fault is displayed in the start
screen.
The temperature transducer can either be operated in SIL
ON or SIL OFF. The standard configuration is SIL ON with
DIP switch S1 set to the OFF position. With the order config-
uration, customer-specific configurations can be selected in

10 Password
The device is protected by means of a four-digit password
set in the factory in order to prevent impermissible changes
to the configuration.
When active, the SIL functionality is displayed in
the start screen.
Default setting: 1111
Example: Display of SIL ON
For safety-related applications, the password set
in the factory must always be changed.
INPUT 1
If the password is lost, it is not possible to reset it.
In this case, please contact Phoenix Contact.
SIL
OK
If, however, only data from the device is to be displayed or
the device is to be used in non-safety-related applications,
the password can be deactivated.
Example: Display of SIL OFF
Setting: 0000
The device can be accessed either via the IFS-OP-UNIT
(Order No.: 2811899) or via a service PC with connected
programming adapter IFS-USB-PROG-ADAPTER (Order
No.: 2811271) and the IFS-CONF configuration software.
INPUT 1
OK
Further information on configuration with the
IFS-OP-UNIT or the IFS-CONF configuration
software can be found in the relevant user manu-
al.
For safety reasons, the SIL function cannot be
switched on again via the IFS-OP-UNIT operator
interface.
WARNING: If Functional Safety is activated by a
reconfiguration or changes are made to the active
Functional Safety configuration, the rules under
Installation and startup must be observed.
SIL can be switched off/deactivated via the SIL
OFF menu item.
To reactivate/switch on the SIL function, PC-
based configuration software, e.g., IFS-CONF is
required.
WARNING: Limitations on safety-related ap-
plications
Only 4 ... 20 mA, limited programming of output
current in the event of line faults
(2 mA ≤ IOut ≤ 3.6 mA or IOut ≥ 21 mA)
If no input is entered for five minutes during con-
figuration, the configuration is ended and any un-
saved data will be lost.
WARNING: Once new configuration data has
been written, the device performs a warm start
that changes the properties of the device. The fol-
lowing control device must be adapted to these
modifications.
NOTE: Transfer and activate the configuration af-
ter the password has been changed.

Appendix - Safety-related applications (SIL 2)
Appendix
A1 Safety-related applications (SIL 2)
Valid hardware and firmware versions
NOTE: Only those devices with SIL designa-
tion and device firmware with revision 0.92 or
higher are certified for SIL 2.
NOTE: The evaluation unit following the measur-
ing transducer (e.g., safety-related PLC) must
recognize these states and correspondingly con-
trol the actuator as the final link in the safety chain.
SIL regulations apply to the following modules:
With the REL versions, an additional signal is generated,
which is compared with up to two specified switching thresh-
olds. When the first threshold is reached, the safety relay is
switched on without confirmation contact and when the sec-
ond threshold is reached, it is switched off. Depending on
the application, the safety for the switching output is imple-
mented by either the series or parallel connection of relays
2 and 3, a fuse connected in series, and by monitoring the
calculated switching value. In the event of deviations of
more than 5%, the device switches to the safe state. The
safe state in this case is an uncontrolled relay.
The hardware is also continuously monitored. If an internal
failure is detected, the measuring transducer also switches
to the safe state (current output < 3.6 mA or > 21 mA or un-
controlled relay).
The transition to the safe state always takes place within the
internal failure detection time of 50 s.
The measuring transducer is released (restarted) by switch-
ing off the supply voltage and switching it back on again, by
resetting the transducer via the serial interface, or by activat-
ing the “Restart” option during configuration. The integrated
startup tests are then performed. If the error is still present,
it will be detected during these tests. If it is still present, the
measuring transducer switches back to the safe state.

The safety-related temperature transducers listed above
from the MACX MCR(-EX)-T-... series have been evaluated
by exida Certification S.A. via a Full Assessment in accor-
dance with IEC 61508 Ed.1.0 to SIL 2.
Certificate number: Phoenix Contact 100134C P0019
C001.
In addition to the safety functions, there are also monitoring
functions for the input and the current output.
Evaluation
Failures which are detected in the measuring transducer
and to which the transducer responds by switching to the
safe state are safe failures (λs).
A1.1 Safety function and safety requirements
The safety-related measuring transducers are used for the
acquisition of a sensor signal (RTD, TC sensors, resistance-
type sensors, mV sources), that is converted into a scaled
signal and from which a standardized “life zero” current sig-
nal is generated. The entire conversion is continuously mon-
itored to a maximum transmission error of 5%. In the event
of greater deviations, the device switches to the safe state.
The safe state is an output signal of either < 3.6 mA or > 21
mA.
Failures where the measuring transducer does not follow a
change of input signal or generates an output signal that de-
viates from the intended value by more than ±5%, are eval-
uated as dangerous failures (λd).
Both safe (λs) and dangerous (λd) failures can be detected
by diagnostic measures. Detected dangerous failures (λdd)
are handled in the same way as safe failures.
The monitoring functions refer to events whose cause is
detected and reported outside of the device.

The total failure rate is: 1.34 * 10-6
Together with the actual signal transmission, continuous
checks and diagnostic functions are performed in the mea-
suring transducers in order to detect faulty behavior.
The MTBF (Mean Time Between Failures) is therefore
85 years.
The probability of a dangerous failure per hour for “continu-
ous demand” mode and the average probability of failure of
the specified function for “low demand” mode are deter-
mined from the error rate:
The internal failure monitoring time (diagnostics test in-
terval) is the time taken to carry out and repeat these tests in
full. Random hardware faults are detected during this time.

The internal failure monitoring time is 50 seconds.

PFH* = 4.3 * 10-8/h
The calculation is performed assuming a checking interval
(TPROOF) of 1 year and a repair time (MTTR) of 24 hours, a
test coverage (CPT) of 95% and a life time (LT) of 10 years.
On the basis of the value determined for the average proba-
bility of failure PFDavg, the checking interval can be in-
creased to up to 5 years.
As a result of the multiple connection options,
only two device types are considered in the con-
figurations for “RTD 3-wire” or “mV” in the follow-
ing. They represent all configurations with a
variable resistance at the input terminals or volt-
age or thermocouple inputs and always indicate
the most conservative case. The two device types
are:
1. MACX MCR(-EX)-T-UI-UP(-SP)(-C)
The values are valid under the following conditions:
2. MACX MCR(-EX)-T-UIREL-UP(-SP)(-C)
–
The failure rates of the components used remain con-
stant throughout the period of use.
FIT (Failure In Time)
1 FIT is 1 failure in 109 hours
–
The propagation of failures by the device in the system
is not taken into consideration.
–
–
The repair time (replacement) is 24 hours.
The failure rates of the external power supply unit are
not taken into consideration.
–
–
The average temperature at which the device is to be
used is 40°C. In this case, normal industrial conditions
are assumed.
The specified failure rates are based on an average am-
bient temperature of 40°C. For an average ambient

A1.3 Configuring an SIL device
The measuring transducer can be ordered with a standard
configuration (see 1.) or configured for safety-related appli-
cations (see 2.), or can be configured by users themselves
for safety-related applications (see 3.).
1. The measuring transducers are delivered with a stan-
dard configuration for safety-related applications with a
4 - 20 mA output (see order key).
2. Customer-specific pre-configured devices (-C) can be
delivered for both safety-related applications and “nor-
mal” usage. Configuration data is shown on a label.
3. The measuring transducers can also be configured by
users for both safety-related applications and “normal”
usage.

•
Load the IFS-CONF configuration software (free down-
load at:
www.phoenixcontact.net/catalog).
Further information on the FDT frame application (IFS-
CONF) and the device drivers (DTM) can be found in
the IFS-CONF user manual.
The package slip is supplied with the device. It can also be
downloaded at: www.phoenixcontact.net/catalog.
Lockable housing with IP54 protection is recommended for
the installation of the measuring transducer.
•
•
Read out the active configuration.
Enter the password in the IFS-CONF in the “PIN” hard-
ware configuration (set to 1111 in the factory).
•
•
•
•
Check that the configuration of the measuring transduc-
er is correct for the intended application.
Connect the measuring transducer according to the in-
stallation instructions.
Make sure that the connected sensor corresponds to
the configuration.
Check the functionality of the measuring transducer
with connected sensor for correct function.
A calibrated sensor simulator (RTD/TC) and a calibrat-
ed digital multimeter are necessary for checking the
measuring transducer.
•
Activate/deactivate SIL.
In the case of “SIL ON”, it is also possible to deactivate the
“Restart after failsafe” item here.
This means that in the event of a failure, the measuring
transducer enters the failsafe state according to the safety
functions, but is not restarted.
•
Write the modified configuration data to the measuring
transducer.
•
Check that the new configuration data in the control
window is correct and confirm with “OK” or “Cancel” if
not correct.
•
Start up the loop and check that it operates correctly.
A1.5 Notes on operation
NOTE: Installation, operation, and maintenance
may only be carried out by qualified specialist per-
sonnel.
Only the green LED (PWR) is on during normal operation.
If a malfunction occurs during operation and the red LED
(ERR) flashes, there is a line fault. The output current of the
measuring transducer is between 2 … 3.6 mA or is higher
than 21.0 mA (in the case of faults in the sensor circuit) or is
0 mA (in the case of a line break in the output circuit).
Check all signal lines. The device will automatically switch
back to normal operation after the fault has been eliminated.
If a fault occurs during operation and the red LED (ERR) is
permanently on, the device has switched to the “safe state”
(output current is less than 2 mA).
WARNING: If Functional Safety is activated by a
reconfiguration or changes are made to the active
Functional Safety configuration, the rules under
“Installation and startup” must be observed.
WARNING: Limitations on safety-related ap-
plications
Only 4 ... 20 mA, limited programming of output
current in the event of line faults
(2 mA ≤ IOut ≤ 3.6 mA or IOut ≥ 21 mA)
Restart the device in order to return it to normal operation.
•
If no PC/laptop has been connected, you can also inter-
rupt the power supply.
WARNING: Once new configuration data has
been written, the device performs a warm start
that changes the properties of the device. The fol-
lowing control device must be adapted to these
modifications.
•
Or you can carry out a warm start with the help of the
configuration software (Service > Reset).
The measuring transducer should then return to normal op-
eration. If it does not, the measuring transducer must be re-
placed.
WARNING: The device must be write-protected
to prevent improper use. Write protection is cre-
ated by assigning a password.

A1.6 Recurring checks (SIL 2)
Phoenix Contact GmbH & Co KG
Abteilung Service und Reparatur
Flachsmarktstr. 8
The function of the entire safety loop must be checked reg-
ularly according to EN 61508 and EN 61511. The intervals
for checking are specified by the intervals of each individual
device within the safety loop.
D-32825 Blomberg
GERMANY
It is the operator's responsibility to select the type of checks
and the checking intervals in the specified time period.
The measuring transducers must be checked at least every
7 years (maximum proof test interval).
Checking must be carried out in such a way that the correct
function of the safety equipment in conjunction with all com-
ponents can be verified.
A1.8 Standards (SIL 2)
The measuring transducers are developed and tested ac-
cording to the following standards:
EN 61508:
2001
Functional safety of electrical/electronic/
programmable electronic safety-related
systems
EN 61326-1:
2006
Electrical equipment for measurement,
control and laboratory use – EMC re-
quirements
Possible procedure for recurring checks for discover-
ing dangerous and undetected device failures.
IEC 61326-3-2: Electrical equipment for measurement,
A calibrated sensor simulator (RTD/TC) and a calibrated
digital multimeter are necessary for checking the measuring
transducer.

•
Connect the sensor simulator to the input of the mea-
suring transducer using the appropriate connection
method.
•
Connect the digital multimeter to the output in current
measuring mode (20 mA range).
The measuring range limits and intermediate values are
specified with the sensor simulator.
The corresponding output values of the measuring trans-
ducer must be checked on the digital multimeter.
Line faults (break and short circuit) are to be simulated on
the input terminals; the configured residual currents are to
be determined on the output.
If the function test result is negative, the measuring trans-
ducer must be taken out of operation and the process put
into a safe state by other measures.
A1.7 Repair
The devices have a long service life, are protected against
malfunctions, and are maintenance-free. However, if a de-
vice should fail, send it back to Phoenix Contact immedi-
ately. The type of malfunction and possible cause must also
be stated.
Please use the original packaging or other suitable safe
packaging when sending devices back for repairs or recali-
bration.
