Precautions

CONNECTION
To avoid malfunction or damage, do not wire the input/output lines
within the same conduit with power lines or high voltage lines.
The cord connected to the Sensor can be extended upto 100 m pro-
vided that the diameter of each wire of thecordis 0.3mm
2
minimum.
 POWER SUPPLY
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, otherwise the Sensor may malfunction due to the switch-
ing noise of the power supply.

STARTUP OPERATION
A maximum of 100 ms is required from the time power is turned on
until the E3S-CL is able to detect objects. If power is supplied to the
loads and the E3S-CL from different sources, turn on power to the
E3S-CL first.
 WATER RESISTANCE
To ensure the water resistance of the E3S-CL, tighten the screws of
the operation panel cover to a torque of 2.5 to 5.0 kgf


Note: 1. The E3S-CL2 maintained a minimum insulation resistance of 100 M
Ω
after the E3S-CL2 was dipped in all the above oils at a
temperature of 50
°
C for 240 hours.
2. When using the E3S-CL2 in a place where an oil other than the ones listed above is sprayed on the E3S-CL2, refer to the
above kinematic viscosity and ph values. The location may be suitable for the E3S-CL2 if the kinematic viscosity and pH values
of the oil are close to the above kinematic viscosity and pH values, but make sure that the oil does not contain any additive that
may have a negative influence on the E3S-CL2.
 CABLE
The E3S-CL2 uses an oil-resistant cord to ensure oil resistivity.
Do not allow the cable to be repeatedly bent during application.
Do not allow the cable to be bent to a radius of less than 25 mm.
 MALFUNCTIONING
If an inverter motor or servomotor is used with the E3S-CL, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, otherwise the Sensor may malfunction.
 MOUNTING
Mounting Direction
Mount the Sensor so that the detection face runs parallel to the sur-
face of the object being detected and not at an angle (see below).
Detection face
Surface of object de-
tected
If detecting a shiny object, mount the Sensor so that the detection
face is at an angle of between 5

and 10

of the surface of the object
being detected. Check to be sure that there is no interference from
the background (see below).
