-Open the UNLOAD doors and locate the UNLOAD doors switch actuator.

-Cycle the switch by hand and have someone watch PLC (Programmable Logic Controller) input indicator #7. It should go “ON” when the switch is down. Do the associated L.E.D.’s (light emitting diode) come “ON” when switch is down?

-If “YES,” wiring is OK

-Check switch placement and door actuation

-If “NO,” check associated:

-Switch and wiring

-Check wiring back to the tumbler junction box

-Check wiring back to the rear controls

-Check PLC (Programmable Logic Controller)

-Refer to blueprints: Main Electrical Panel Diagram

-Tumbler junction box diagram

-Rare panel controls wiring diagram

-Re-test; verify that the signal is operational

4.0“DRUM FAULT MESSAGE” Malfuntion a) PROBABLE CAUSES;

1.Stop Motion Detector module or sensor

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

- If the L.E.D. if off, refer to section 1a

1a) If the LED is off:

-Check Fuse 2; replace if necessary

-Rotate the tumbler using the pendant control, and adjust the stop

-Does the module’s L.E.D. respond?
