3.0“DOOR Open” Problem

A “DOOR OPEN” message is generated by either the heater, the LOAD doors, or UNLOAD doors. The following information will address the LOAD doors and the UNLOAD doors signals, since they are associated with the tumbler (basket) junction box.

a.PROBABLE CAUSES;

1)WIRING BACK THE PLC (Programmable Logic Controller)

DS1-B=LOAD DOOR SWITCH DS2-B=UNLOAD DOOR SWITCH

b.POSSIBLE SOLUTIONS;

1)For quick check of LOAD and UNLOAD signals of the PLC perform the following:

Remove factory air from the dryer

With the Control Voltage “ON,” open the LOAD doors and locate the LOAD door switch actuator

Cycle the switch by hand and have someone watch PLC input indicator #6. It should go “ON” when the switch is down.

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 okay

Check switch placement and door actuation

If “NO,” check associated:

Switch and wiring

Check wiring back to the tumbler (basket) junction box

Check wiring back to the rear controls

Check PLC (Programmable Logic Controller)

Refer to the blueprints: Main Electrical Panel Diagram

Tumbler (basket) junction box diagram
