NPN three wire proximity sensor. We don’t guarantee that MRC-Pro will work with all types of NPN sensors. To ensure quality, please contact us for your sensor needs.
Check power source and harness connections.
Check the harness and connections to the sensor/switch (see mounting directions in the operator’s manual.)
Ensure the fork-plate is mounted in the right direction (the narrow fork on the plate should pass the sensor first). Slow the drum speed and check if the decimal point on the counter display blinks twice after the fork passes the sensor. Check mounting dimensions of the sensor.
Check the mounting of the fork plate (see user manual). Counter may be configured for incorrect application (see user manual).
Ensure that the face of the sensor is at least 2 ¾ inches away from the sensor bracket. If it is, make sure there are no other metal objects in the vicinity of the sensor.
The fork plate is most likely mounted backwards. See “Mounting the Sensor” in the User Manual for proper plate arrangement.
