PROBABLE SOLUTIONS;
1) Verify that
ALL
motor protection devices (manual starters) have their START buttons pushed in.
If any device has tripped, reset it and restart the dryer. If the same devices continue to trip:
Verify current setting
Check circuit
Check motor
Retest
2) Verify that the associated output L.E.D. (light emitting diode) on the PLC (Programmable Logic
Controller) is active. Verify that the associated output signal protection fuse is good. Check associated
PLC output circuit wiring to associated motor starter coil (A terminals).
3) Retest
4) Check associated motor starter circuit wiring to and from motor starters, and to the associated
motors themselves. Refer to the ADS-464 Main Panel Wiring Diagram; retest.
