Installation
J
BEAM AXIS AND SENSITIVITY ADJUSTMENTS
Set the sensitivity adjuster of the Receiver to maximum.
Move the Emitter and Receiver vertically and horizontally and
secure the Emitter and Receiver in the center of the range
within which the OPERATION indicator is ON.
Let the sensing object pass through the sensing range and
adjust the sensitivity so that the OPERATION indicator is ON
and OFF.

Adjustment
procedure
Set the sensitivity adjuster of the
receiver to max.
Move the Emitter and Receiver
vertically and horizontally and
secure the Emitter and Receiver in
the center of the range within which
the OPERATION indicator is OFF.
Let the sensing object pass through
the sensing range and adjust the
sensitivity so that the OPERATION
indicator is ON and OFF.

Precautions
J
MUTUAL INTERFERENCE
If more than one Sensor is closely mounted together or used in a
narrow space, the mutual interference of the Sensors will result.
J
WIRING
Do not wire the lines of the E4E along with high-tension or power
lines in the same conduit or close together, otherwise the E4E
may malfunction due to inductive noise.
J
SENSITIVITY ADJUSTMENT
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.
J
POWER SUPPLY
If a standard switching regulator is used, ground the FG and G
terminals.
J
POWER ON
The E4E needs a maximum of 100 ms to be ready to operate
after the E4E is turned ON. If power is supplied to the E4E and
the load independently, be sure to turn ON the E4E first.
J
OUTPUT SHORT-CIRCUIT
The E4E has a built-in circuit protecting the output from
short-circuit damage. If the circuit is triggered, the output will not
operate. Turn OFF the E4E, check the condition of the load, and
then turn ON the E4E again.
