(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(c) On the MCDU, get the ELEC menu on the SYSTEM REPORT/TEST page (Ref. AMM TASK 31-32-00-860-004).
B. Test
NOTE : Before you do the test of the TR2, make sure that the AC BUS 2
____
supplies its primary winding, in any RESET mode.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: - push the ELEC key. On the upper ECAM DU:- the TR2 FAULT message comes into view.
On the lower ECAM DU, on the ELEC page: - the line connection between the TR2
and the DC2 busbar is not shown, - the DC BAT busbar energizes the DC2 busbar, - the TR2 indication is shown in amber, the value is 0 A and is shown in
amber.
2. On the MCDU: - push the line key adjacent to the TR2 indication, The TR2 page comes into view.
- push the line key adjacent to the RESET indication. If on the TR2 page:- the NO FAULT indication comes into
NOTE : If the CFDS is not____ available, you can reset with the TR RESET pushbutton switch (15PU) which is on the relay box 103VU. view, andOn the lower ECAM DU, on the ELECpage:- the TR2 supplies the DC2 busbar.Stop the trouble shooting.
If on the TR2 page: - the TR2 indication comes into view.
On the ELEC page: - the line connection between the TR2
and the DC2 busbar is not shown, - the DC2 busbar is not shown.
Continue the trouble shooting (Refer to the fault isolation which follows).

A. If the test confirms the fault:
- do a check of the status of the circuit breakers 4PU2 and 2PU2.
(1) If the circuit breakers are closed:
- do a check of the TR2 voltage on the lower ECAM DU, on the ELEC page.
(a) If the TR2 voltage value is approximately 28VDC:
- replace the CNTOR-TR 2 (5PU2) (Ref. AMM TASK 24-32-55-000-001) and (Ref. AMM TASK 24-32-55-400-001).
1 If the fault continues:
_
- do a check and repair the wiring between the TR2 28VDC outlet and the TR2 pin B/F (Ref. ASM 24-32/01).
2 If the fault continues:
_
- replace the CNTOR-TR 2/AC SVCE BUS NORM SPLY (14PU) (Ref. AMM TASK 24-32-55-000-001) and (Ref. AMM TASK 24-32-55-400-001).
(b) If the TR2 voltage value is 0VDC and shown in amber:
- do a check for 115VAC on the pins M, L,K of the contactor (14PU).
1 If there is 115VAC:
_
- replace the TR-2 (1PU2) (Ref. AMM TASK 24-32-51-000-001) and (Ref. AMM TASK 24-32-51-400-001).
2 If there is no 115VAC:
_
- do a check for 115VAC on the pins D, E, F of the contactor (14PU).
a If there is 115VAC:
_
- replace the RELAY GND/FLT SELECT CTL(7XX).
. If the fault continues:
- replace the CNTOR-TR 2/AC SVCE BUS NORM SPLY (14PU) (Ref. AMM TASK 24-32-55-000-001) and (Ref. AMM TASK 24-32-55-400-001).
. If the fault continues:
- replace the CNTOR-AC & DC GND SVCE SPLY (14XX) (Ref. AMM TASK 24-42-55-000-001) and (Ref. AMM TASK 24-42-55-400-001).
- do a check and repair the wiring between:
