B. Test
(1) Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the ECAM control panel: On the upper ECAM display unit:
- push the ELEC key to get the ELEC - the ELEC DC ESS BUS SHED warning
page. comes into view.
(2) Do the operational test of the CVR channel recording (test of the CVR only) (Ref. AMM TASK 23-71-00-710-001).
4. Fault Isolation
_______________
A. Table of the circuit breakers used in this procedure:
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------
106VU EMER/SHED/CNTOR/SPLY 1PH C07
B. If the test confirms the fault:
- do a check of the status of the circuit breaker (1PH).
(1) If the circuit breaker (1PH) is closed:
- do a check for 28VDC between pins B/5 and B/3 of the DC SHED ESS BUS contactor (8PH) (Ref. ASM 24-62/01).
(a) If there is 28VDC on the contactor (8PH):
- replace the CNTOR-DC SHED ESS BUS (8PH) (Ref. AMM TASK 24-62-55-000-001) and (Ref. AMM TASK 24-62-55-400-001).
(b) If there is no 28VDC on the contactor (8PH):
- do a check for 28VDC at pin A/B2 of the B hydraulic pump control relay (21XE).
1 If there is 28VDC on the relay (21XE):
_ - replace the RELAY-B HYD PUMP CTL (21XE).
a If the fault continues:
_
- do a check and repair the wiring between: . pin A/B3 of the B hydraulic pump control relay (21XE) and pin B/3 of the DC SHED ESS BUS contactor (8PH), . pin B/5 of the DC SHED ESS BUS contactor (8PH) and the ground point or terminal block (Ref. ASM 24-62/01) and (Ref. AWM 24-62-02).

2 If there is no 28VDC on the relay (21XE):
_
- do a check for 28VDC at pin A/B2 of the static inverter control relay (6XB).
a If there is 28VDC on the relay (6XB):
_
- replace the RELAY - STAT INV CTL (6XB). . If the fault continues: do a check and repair the wiring between pin A/B3 of the static inverter control relay (6XB) and pin A/B2 of the B hydraulic pump control relay (21XE) (Ref. ASM 24-62/01).
b If there is no 28VDC on the relay (6XB):
_
- do a check and repair the wiring between the: . pin A/F of the DC ESS BUS supply contactor (4PC) and pin 1 of the EMER/SHED/ CNTOR/SPLY circuit breaker (1PH), . pin A/2 of the EMER/SHED/CNTOR/SPLY circuit breaker (1PH) and pin A/B2 of the static inverter control relay (6XB) (Ref. ASM 24-62/01) and (Ref. AWM 24-62-02).
(2) If the circuit breaker trips:
- do a check for a short to ground between the circuit breaker (1PH) and pin B/5 of the contactor (8PH) (Ref. ASM 24-62/01).
(a) If there is a short to ground:
- replace the CNTOR-DC SHED ESS BUS (8PH) (Ref. AMM TASK 24-62-55-000-001) and (Ref. AMM TASK 24-62-55-400-001).
(b) If there is no short to ground:
- replace the C/B EMER/SHED/CNTOR/SPLY (1PH).
C. Do this test to make sure that the system operates correctly:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: On the upper ECAM display unit:
- push the ELEC key to get the - no warning comes into view. ELEC page.
On the lower ECAM display unit:
- the normal configuration comes into view.
2. On the overhead control and - on the pushbutton switch, the ON
indicating panel 21VU: legend comes on
- push the RCDR/GND CTL - make sure that you can hear the
pushbutton switch. conversations from the CVR microphone in the headset.
