A. If the test confirms the fault:
- do a check of the status of the circuit breaker (2XX)
(1) If the circuit breaker is closed:
- do a check for 115VAC on the pins 1, 2, 3 of the module 20XX (Ref. ASM 24-42/01).
(a) If there is no 115VAC:
- do a check of the wiring between the circuit breaker (2XX) and the module 20XX (Ref. ASM 24-42/01).
(b) If there is 115VAC:
1_ If there is no continuity:
- repair the wiring.
2_ If there is continuity:
- replace the C/B-SVCE/BUS2/212XP SPLY (2XX).
- replace the CNTOR-AC GND SVCE SPLY (12XX) (Ref. AMM TASK 24-42-55-000-001) and (Ref. AMM TASK 24-42-55-400-001).
1 If the fault continues:
_
- replace the CNTOR-AC SVCE BUS NORM SPLY (12XN) (Ref. AMM TASK 24-51-55-000-001) and (Ref. AMM TASK 24-51-55-400-001).
2 If the fault continues:
_
- do a check and repair the wiring: . between the pin B/3 of the contactor (12XX) and the pin B/10 of the contactor (12XN) . between the pin B/5 of the contactor (12XX) and the first terminal block . between the pin B/12 of the contactor (12XN) and the first terminal block (Ref. ASM 24-42/01).
(2) If the circuit breaker is open:
- close it.
(a) If the circuit breaker trips:
- do a check of the wiring between the circuit breaker (2XX) and the busbars (212XP) and (216XP) (Ref. ASM 24-42/01).
1 If there is a short to ground:
_ - repair the wiring.
2 If there is no short to ground:
_ - replace the C/B-SVCE/BUS2/212XP SPLY (2XX).
