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
