B. Job Set-up
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(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 SYSTEM REPORT/TEST/ELEC page (Ref. AMM TASK 31-32-00-860-004).

C. Test
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel:
- push the STS key.
2. In the AC power center 123VU: - open the circuit breaker 2PU1.
3. On the MCDU:
- push the line key adjacent to the TR3 indication.
Or (if the CFDS is not
available):
In the relay box 103VU:
- push TR RESET pushbutton switch (15PU).
4. In the AC power center 123VU:
- close the circuit breaker
(2PU1)
4. Fault Isolation
_______________
A. If the test confirms the fault:On the upper ECAM DU:
- these warnings come into view: . ELEC TR1 FAULT, . ELEC TR2 FAULT, . ELEC ESS TR FAULT, . ELEC ESS BUS FAULT.
On the lower ECAM DU, on the STATUS page:
- the DC BUS TIE indication comes into view.
- replace the TR-ESS (1PE) (Ref. AMM TASK 24-34-51-000-001) and (Ref. AMM TASK 24-34-51-400-001).
(1) If the fault continues:
- do a check and repair the wiring between respectively: . the pin B/J of the ESS TR and the pin AB/7A of the CFDIU (1TW) . the pin 6 of the pushbutton switch (15PU) and the first branch point . the pin 5 of the TR RESET pushbutton switch (15PU) and the ground . the pin B/E of the ESS TR and the pin AA/7K of the CFDIU (Ref. ASM 24-34/01).

5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) On the MCDU, push the line key adjacent to the RETURN indication until the CFDS menu page comes into view.
(2) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
