Motor Protection Device Descriptions

The motor protection devices in the AD-464 incorporate a manual disconnect switch, thermal overload relay, and instantaneous trip mechanism in one compact device. A two (2) position, normally open, auxiliary contact block has been attached toALL motor protection devices to provide the “MOTOR FAULT” display message, and shut down “ALL” motors in the event a motor should trip.

1.Motor Actuation Problems

a) PROBABLE CAUSES;

1a) Motor Protection Device “OFF” or “TRIPPED.”

2a) PLC (Programmable Logic Controller) Output Signal Defective

3a) Motor Circuit Wiring

b)PROBABLE SOLUTIONS;

1b) 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

2b) 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).

3b) Retest

4b) Check associated motor starter circuit wiring to and from motor starters, and to the associated motors themselves. Refer to the AD-464 Main Panel Wiring Diagram; retest.
