SYNC BUS Short
Check for a wiring short. Check for improperly wired NAC
circuit. (If an appliance is wired + to – and – to + a short trouble
will be indicated.

SYNC BUS Open
Check SYNC BUS terminals for good connections. Check NAC
circuit wiring for continuity. Check NAC circuit for 10K Ohm
EOLR.

Note 1: When LED indicator D3 is lighted, it indicates a general ground fault condition. Momentarily depress switch
SW5 (Ground Fault Detect Enable Pushbutton). The Coded Trouble LEDs will indicate the circuit location of the
ground fault.
FUSE REPLACEMENT PROCEDURE (All Models):
