  • wiring from the proximity switch (13WV2) to the indicator light (1WN2)
  • wiring from the proximity switch (13WV2) pin C to the ground
  • RELAY-PWR SPLY SWITCHOVER [12WN]
  • wiring from the relay (12WN) to the indicator light (1WN2)
  • C/B-EIS/SLIDES/ARM AND WARN/FLT [15WN]
  • wiring from the circuit breaker (15WN) to the relay (12WN)

4. Fault Isolation
Subtask 52-11-00-810-052-A
A. If the test confirms the fault:
  • Do a check of the circuit breaker (15WN) status ASM 527301.
   (1) If the circuit breaker is closed:
  • Do a check for 28VDC at pin A of the indicator light (1WN2) ASM 527301.
     (a) If there is 28VDC:
       1 If the fault continues:
  • Do a check for a ground signal at pin C of the proximity switch (13WV2) ASM 315405.
         a If there is a ground signal:
  • Do a check and repair the wiring from the proximity switch (13WV2) to the indicator light (1WN2) pin B to pin F ASM 315405 and ASM 527301.
         b If there is no ground signal:
  • Repair the wiring from the proximity switch (13WV2) pin C to the ground, ASM 315405.
     (b) If there is no 28VDC:
  • Do a check for 28VDC at pin A/A1 of the relay (12WN) ASM 527301.
       1 If there is 28VDC:
         a If the fault continues:
  • Do a check and repair the wiring from the relay (12WN) to the indicator light (1WN2) pin A/A2 to pin A ASM 527301.
       2 If there is no 28VDC:
  • Do a check of the wiring from the circuit breaker (15WN) to the relay (12WN), pin 2 to pin A/A1.
         a If there is continuity:
         b If there is no continuity:
  • Repair the wiring from the circuit breaker (15WN) to the relay (12WN) pin 2 to pin A/A1 ASM 527301.
   (2) If the circuit breaker is open:
     (a) If the fault continues:
