“A” provides rear door position signal to the PLC (Programmable Logic Controller). “B” is a rear interlock to the burner controller circuit.
c)Drum Rotation Sensor – PRS1
The drum rotation sensor is an inductive pick up device located on the left wrapper of the tumbler (basket) section. Its function is to sense a metal “target” attached to the “basket” as it rotates. The mechanical adjustment of this device, (distance from the target) is crucial (3/16” [4.7 mm] maximum from target).
CAUTION: DO NOT MECHANICALLY ADJUST THE ROTATIONAL SENSOR SO FAR IN TO BE HIT BY THE ROTATING TARGET, PERMANENT DAMAGE OF THE SENSOR WILL OCCUR.
