R 4. Fault Isolation_______________
R A. If the test confirms the fault:
On the lower ECAM DU, ELEC page:
- the line connection between TR2 and DC 2 does not come on.
- the DC BAT busbar energizes the DC 2 busbar
- the TR2 indication is shown in amber and the value of the current is 0A.
On the upper ECAM DU:
- the TR2 FAULT message does not come into view.
On the MCDU:
- the TR page comes into view.
On the MCDU:
- the TR2 page comes into view.
On the MCDU, on the TR2 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 TR2 (1PU2) indication comes into view, refer to (Ref. TASK 24-32-00-810-802) for the 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 TR2 and the pin A/X2 of the relay 8PC2,
R . the pin A/X1 of the relay 8PC2 and the first branch point (Ref. ASM R 24-35/02). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 电源 3(44)
