- replace the defective unit.

 B. Electric Test
 (1) Do the operational test of the Emergency generation system (Ref. AMM TASK 24-24-00-710-001).
 (a) Do the trouble shooting given in Para. 4.B. when, during the operational test:
 1  on the lower ECAM display unit:
_
 - the line between AC 1 bus and AC ESS bus comes on,

 - the line between DC 1 bus and DC ESS bus comes on,

 - the line between EMER GEN and AC ESS bus goes off,

 - the line between EMER GEN and ESS TR goes off,

 - the EMER GEN voltage and frequency come on green.

 (b) Do the trouble shooting given in Para. 4.C. when, during the operational test:
 1 on the lower ECAM display unit:
_
 - the line between AC 1 bus and AC ESS bus comes on,

 - the line between DC 1 bus and DC ESS bus comes on,

 - the EMER GEN voltage and frequency are shown in amber.

 (c) Do the trouble shooting given in Para. 4.D. when, during the operational test:
 1 on the lower ECAM display unit:
_
 - the line between DC 1 bus and DC ESS bus comes on,

 - the line between ESS TR and DC ESS bus goes off.

 (d) Do the trouble shooting given in Para. 4.E. when, at the end of the operational test:
 1 on the EMER ELEC PWR section of the panel 21VU:
_
 - when the EMER GEN TEST pushbutton switch is released, the CSM/G and the Blue electric pump do not stop automatically.
R (e) Do the trouble shooting given in Para. 4.F. when, during the
R operational test:

R 1_ On the EMER ELEC PWR section of the panel 21VU:
R - when you push the EMER GEN TEST pushbutton switch (23XE) and
R also when you keep it pushed, the CSM/G (8XE) and the blue
R electrical pump (2075GJ) start and stop after 10 seconds.

 4. Fault Isolation
_______________
 A. Table of the circuit breakers used in this procedure:
 -------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------105VU ELEC/CSM/G /EV AUTO/SPLY 7XE C01 106VU CSM/G /EV/MAN/SPLY 6XE B04 106VU ESS TR/CNTOR/CTL 5PE C02
 B. If the test confirms the fault:
 - replace the RELAY-EMER CONDITION (12XE).
 (1) If the fault continues:
 - do a check and repair the wiring between respectively: . the pin X of the CSM/G control unit (1XE) and the pin A/X of the EMER CONDITION relay (12XE) . the pin A/Z of this relay (12XE) and the ground (Ref. ASM 24-24/02).

 May 01/03 CES C. If the test confirms the fault:

 - on the EMER ELEC PWR panel 21VU, open the guard, push and hold the EMER GEN TEST pushbutton switch and at the same time do a check for 28VDC on the pin A/b of the CSM/G control unit (1XE) (Ref. ASM 24-24/02)
 NOTE : There is 28VDC during 6 s only.
____
 (1) If there is 28VDC:

 - replace the CONTROL UNIT-CSM/G (1XE) (Ref. AMM TASK 24-24-34-000-001) and (Ref. AMM TASK 24-24-34-400-001).
 (a) If the fault continues:

 - replace the CSM/G (8XE) (Ref. AMM TASK 24-24-51-000-001) and (Ref. AMM TASK 24-24-51-400-001).

 (b) If the fault continues with the Blue electric pump in operation:

 - replace the ELEC PUMP-B (2075GJ) (Ref. AMM TASK 29-12-51-000-001) and (Ref. AMM TASK 29-12-51-400-001).

 (2) If there is not 28VDC:

 - replace the RELAY-EMER GEN TEST CONDITION (16XE), RELAY-EMER AUTO LOG CONDITION (17XE), RELAY-EMER AUTO LOG CONDITION (18XE), RELAY-RAT EXTN INHIB CONDITION (20XE), RELAY-CSM/G EV SPLY MONG (22XE), RELAY (3PH), RELAY-BUS 1XP CTL (15XC), RELAY-BUS 2XP CTL (16XC) and P/BSW-EMER ELEC PWR/EMER GEN TEST (23XE).

 (3) If the fault continues:

 - do a check of the status of the circuit breakers (6XE) and (7XE).
 (a) If they are closed:
 - do a check and repair the wiring between respectively: . the circuit breaker (6XE) and the pin 7 of the pushbutton (23XE) . the pin 8 of the pushbutton (23XE) and the pin A/X of the relay (16XE) through the relays (15XC) and (16XC) . the circuit breaker (7XE) and the pins A/X1 and A/B2 of the relay (20XE), through the relays (17XE) and (18XE) . the pin A/X2 of the relay (20XE) and the ground, through the relay (16XE) . the pin A/B1 of the relay (20XE) and the pin A/X1 of the relay (22XE) . the pin A/X2 of the relay (22XE) and the ground . the pin A/B1 of the relay (20XE) and the pin A/b of the CSM/G control unit (1XE), through the relays (22XE) and (3PH) (Ref. ASM 24-24/02).
