4B Binswitch BS1V3FC, Operation Manual

WARNING

If the system does not immediately shutdown as expected or alarm as required, then remove the 

machine from service until the problem has been diagnosed and corrected.

TESTING AND COMMISSIONING

1.  Check that the unit is correctly installed (see standard wiring diagram).

2. 

After going through the sensor calibration steps, the red LED should be “ON”.

3.  Introduce material to the Binswitch.  If calibrated correctly, the Binswitch will activate when material 

has been detected.  Machinery shut down will depend on your specific monitoring setup.  4B 

recommends an instant shutdown when maximum fill level or a plug condition has been detected.
