If more than one Sensor is used in one place, the Sensors
need to be in synchronous operation for the prevention of
mutual interference. A maximum of four Sensors can be in
synchronous operation.

Connect the DC power supply and Sensor to each Amplifier
as usual.
Use the E99-C (order separately) connector to connect the
Sensor to the Amplifier.
If the case of the connections shown in the following illustra-
tion, set the selector of only one Amplifier (No. 1 in the follow-
ing case) to MON. Set the selector of any other Amplifier to
SYN. In “MON” mode, the amplifier generates a pulse. In
“SYN” mode, the pulse is inhibited.

Note: The load in operation is connected to the output circuit of
the E4C.
Note: The E99-C Connector will be most effective if the E4C is a
reflective model although the E99-C Connector is required
by both the reflective and through-beam models. When
using through-beam models, however, be sure to maintain
enough space between adjacent Sensors to suppress
mutual interference. Refer to Sensitivity Adjuster Position

Pass the target object through the sensing range and adjust the
sensitivity so that the SENSING indicator turns ON and OFF
according the presence or absence of the object while the
STABILITY indicator is lit continuously.
J SENSITIVITY/ZONE ADJUSTMENTS
E4C-TS50 and E4C-WH4T Through-beam Models
Set the SENSITIVITY adjuster of the Receiver to maximum.
If the STABILITY indicator is not lit while the Sensor is in
operation, this may indicate a possible operational error. Check
or readjust the sensitivity.
Move the Emitter and Receiver vertically and horizontally until the
SENSING indicator of the Receiver is lit and secure the Emitter
and Receiver at the midpoint of the range within which the
STABILITY indicator is lit.
If the Emitter and Receiver are set at a distance shorter than the
rated sensing distance, reduce the sensitivity to within the range
in which the STABILITY indicator is lit. This will increase the
immunity of the Sensor against noise.

Precautions
J SENSOR MOUNTING ANGLE
If the E4C is in level control or distance control of sensing
objects, the stability of signal detection will depend on the
sensing surface condition of the objects. Considering the repose
angle of the objects, mount the E4C so that the ultrasonic beam
and the sensing surface of each object meet at right angles to
each other.
The jetting sound of air nozzles includes noise of a wide
frequency range, which will affect the operation of the E4C. Do
not use an air nozzle near the E4C.
The sensing distance of the E4C will decrease if there is any
water drops on the surface of the emitter or receiver.
The reflective model may not detect any objects if there is any
object absorbing sound, such as powder and cotton, on the
surface of the emitter or receiver.
J SURROUNDING OBJECTS
J MUTUAL INTERFERENCE
Make sure that the Sensor is free from surrounding objects that
reflect the ultrasonic beam diffusion, or the Sensor may
malfunction. In particular, pay the utmost attention so that no side
lobe of the ultrasonic beam will be reflected by such objects.
If more than one Unit is closely mounted together or used in a
narrow space, the mutual interference of the Sensors will result.
To prevent this, set the MON/SYN selector to SYN and check
that no mutual interference results.
J MOUNTING
J CONNECTIONS
Securely mount the E4C by using the nuts provided with the E4C
or the mounting holes of the E4C. Refer to Dimensions for
details.
The cord length between the Sensor and Amplifier can be a
maximum of 20 m provided that the cord is a three-conductor,
shielded cord (6 dia., UL2791) with 7/0.25 dia. If the Emitter is the
E4C-TS50S, however, use a two-conductor, non-shielded cord
(6 dia. UL20276) with 7/0.25 dia.
Do not strike the Sensor with any hammer or other object,
otherwise the E4C will no longer be water-resistant.
Do not wire the lines of the E4C along with high-tension or power
lines in the same conduit or close together, otherwise the E4C
may malfunction due to inductive noise.
If the E4C is not mounted securely, the E4C may be damaged by
vibration or may not detect sensing objects accurately due to a
possible change in the mounting position.
The power supply lines of the Amplifier can be extended up to
100 m provided that the size of the cord is 0.3 dia. or more.
J ENVIRONMENTAL CONDITIONS
Do not use the E4C at a temperature exceeding the rated range
or outdoors, otherwise the reliability and life of the E4C will
decrease.
J ADDITIONAL PRECAUTIONS
Be sure not to turn the sensitivity adjuster excessively. If the
sensitivity adjuster is turned exceeding the permissible range, no
sensitivity adjustment will be possible again.
The Ultrasonic Reflective Sensor utilizes the air as a beam
transmission media. Do not use the E4C in places with radical
convection or extreme local temperature changes. For example,
if there is a hot air curtain that causes turbulence within the
sensing area, the E4C may malfunction.
Take the measures shown in the following illustrations if multiple
reflection results.
Air curtain
Turbulence
5-dia. slit
Emitter
Wall
Wall
Urethane rubber or sponge
The sensing distance will be, however, reduced to half (i.e., 10 to
17 cm) if the slit is used.
Receiver
If the sensing zone is set to a small value (i.e., a few centimeters)
on the E4C reflective model, the E4C may require a warming-up
time of 3 minutes or more after the E4C is turned ON.
