Operation
Sensitivity adjustment
Remove the rear rubber cap of the E2K-C and turn the poten-
tiometer in the hole to adjust the sensitivity of the E2K-C.
Remove this rubber
cap and adjust the
potentiometer.
The sensing distance increases by turning the potentiometer
clockwise and decreases by turning the potentiometer coun-
terclockwise. The potentiometer can make 15±3 valid turns
and then make slip turns because the potentiometer does not
have a stopper. The slip turns will not, however, damage the
potentiometer.
1. Slowly turn the potentiometer clockwise until the E2K-C
turns on with no sensing object.
Potentiometer
Stop turning the potentiometer
at the moment the E2K-C turns off.
2. Turn the potentiometer counterclockwise until the E2K-C
turns off with the sensing object located within the sensing
distance.
Potentiometer
Stop turning the potentiometer
at the moment the E2K-C turns off.
3. The E2K-C will be in stable operation if there is a difference
of 1.5 turns or more between the points the E2K-C is turned
on and off, otherwise the E2K-C will not be in stable oper-
ation.
The point the
E2K-C turns on.
Stable detection if the
difference is 1.5 turns or more.
The point the
E2K-C turns off.
4. Set the potentiometer midway between the two points.
The point the
E2K-C turns on.
Midway
The point the
E2K-C turns off.
5. If the distance of each sensing object varies, take step 2
with the sensing object located at the farthest sensing dis-
tance to be applied.
