2) Wiring back to main electrical enclosure

b. PROBABLE SOLUTIONS;

1) Open the Main Electrical Enclosure locate input #0, 10 on the PLC (Programmable Logic Controller).

With control voltage “ON” (“green” Push-Button), use the pendant to rotate the tumbler (basket).

Notice a L.E.D. (light emitting diode) on as the tumbler (basket) is rotating.

• If the L.E.D. (light emitting diode) is off, refer to section #1a

1a) If the LED (light emitting diode) is off:

• Rotate the tumbler (basket) using the pendant control, and adjust the stop

• Does the module’s L.E.D. respond?

• If yes, adjust the “Time Adjust” until the L.E.D. (light emitting diode) is on during rotation 15 to

20 seconds after the tumbler (basket) stops

• If “NO,” check:

• Inductive proximity sensor is located in the same area as the tumbler (basket) junction box
