American Dryer Corp ADS-464 II manual Probable Causes

Page 70

a. PROBABLE CAUSES

1)The lint screen must be cleaned every five (5) drying cycles

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

3)Clogged lint screen or lint bag

4)Air pressure setting

5)Air pressure switch - PS3 or wiring back to the PLC (Programmable Logic Controller) b. PROBABLE SOLUTIONS;

1)Perform preventive maintenance and screen cleaning procedures.

2)Set correct pressure settings.

3)For a quick check of the AIR PRESSURE SWITCH WIRING, perform the following:

Run a drying cycle

Does the pressure switch’s indicator come “ON”?

If “YES,” switch and its adjustment are okay

If “NO,” check switch and its adjustment

Verify that PLC (Programmable Logic Controller) input L.E.D. (light emitting diode) #5 comes “ON”

Does L.E.D. #5 come “ON” when the switch is active?

If “YES,” wiring is okay

If “NO,” check:

Switch, its setting and wiring

Check wiring back to the base electrical junction box

Check PLC (Programmable Logic Controller)

Refer to the blueprints: Main Electrical Panel Diagram, Base Junction Box Wiring Diagram

Retest; verify that the signal is operational
