Initial Actions
Check Circuit Breaker.
Procedure
110/220/240 VAC is measured between the Noise Filter PWB FS75 (+) and FS74 (-).
YN
110/220/240 VAC is measured between the Circuit Breaker j72-1 (+) and j72-1 (-).
YN
Disconnect power cord from power outlet. The voltage of the power outlet is 110/
220/240 VAC.
YN
Inform customer power is not available.
Check the Power Cord for an open circuit. If no problems are found, replace the Cir-
cuit Breaker (PL 9.2).
Check wire between Circuit Breaker j72 and Noise Filter PWB for an open circuit and poor
contact.
110/220/240 VAC is measured between the Noise Filter PWB fs77 (+) and fs76 (-).
YN
If the Circuit Protector on the Noise Filter PWB is tripped, reset it. If it is not tripped,
replace the Noise Filter PWB (PL 9.2).
110/220/240 VAC is measured between the Main Power Switch FS57 (+) and Noise Filter
PWB fs76 (-).
YN
Check the wire between the MAIN POWER Switch and the NOISE FILTER PWB for an
open circuit and poor contact.
110/220/240 VAC is measured between the Main Power Switch FS69 (+) and Noise Filter
PWB fs76 (-).
YN
Replace the Main Power Switch (PL 9.2).
100 (FX), 110 (TFX) or 220-240 (AP) VAC is measured between the AC Drive PWB fs40 (+)
and the fs39 (-)?
YN
Check the wire between the AC DRIVE PWB and the Main Power Switch for an open cir-
cuit and poor contact.
100 (FX), 110 (TFX) or 220-240 (AP) VAC is measured between the AC drive PWB j43-9 (+)
and the j43-1 (-).
YN
Replace the AC Drive PWB (PL 9.2).
Check the AC circuit distribution by referring to Chapter 7 Wiring Data.
