6.Lint Screen Mechanism Problem “SCREEN FAULT”

A “SCREEN FAULT” message is generated by the incorrect state of the lint screen mechanism sensor switch. The following information will address the correct signal, since it is associated with the Base Electrical Junction Box.

a)PROBABLE CAUSES;

1a) The Lint Screen must be cleaned every five (5) drying cycles.

2a) Wiring back to the PLC (Programmable Logic Controller) 0, 8.

b)PROBABLE SOLUTIONS;

1b) The software has incorporated in it a clean lint screen verification, if the lint screen is not cleaned at the end of five (5) drying cycles. The AD-464 will not allow another drying cycle until the lint screen is cleaned.

2b) A defective lint drawer proximity switch.

Have someone verify that PLC (Programmable Logic Controller) input L.E.D. (light emitting diode) #8 lights, when the lint drawer is in and off when the drawer is out.

Does L.E.D. (light emitting diode) #8 come “ON” when the lint drawer is out?

If yes, wiring is OK

If no, check associated:

Proximity Switches and Wiring

Check wiring back to the Base Junction Box.

Check PLC (Programmable Logic Controller).

Refer to Wiring Diagrams:

Main Electrical Panel Diagram

Base Electrical Junction Box Wiring Diagram.

Retest; verify that the signal is operational.
