R 4. Fault Isolation_______________
R A. If the test confirms the fault:
On the lower ECAM DU:
- the line connection between the TR1 and the DC 1 busbar does not come on.
- the DC 2 busbar energizes the DC 1 busbar through the DC BAT busbar
- the TR1 indication is shown in amber and the value of the current is 0A.
On the upper ECAM DU:
- the TR1 FAULT message does not come into view.
On the MCDU:
- the TR page comes into view.
On the MCDU:
- the TR1 page comes into view.
On the MCDU, on the TR1 RESET page:
- if the NO FAULT indication comes into view, and that
- on the lower ECAM DU , ELEC page, the normal configuration comes into view: do the trouble shooting given in Para. 4.A.
- if the TR1 (1PU1) indication comes into view, refer to (Ref. TASK 24-32-00-810-801) for trouble shooting. Then, do the trouble shooting given in Para. 4.A.
R - do a check of the wiring between:
R . the pin B/E of the TR1 and the pin A/X2 of the relay 8PC1,
R . the pin A/X1 of the relay 8PC1 and the first branch point (Ref. ASM R 24-35/02).
R (1) If there is no continuity:
R - repair the wiring.
R (2) If there is continuity:
R - replace the RELAY-SWTG SPLY/TR 1 FAULT (8PC1).

R (3) If the fault continues:
R - replace the TR-1 (1PU1), (Ref. AMM TASK 24-32-51-000-001) and (Ref.
R AMM TASK 24-32-51-400-001).
