R 4. Fault Isolation
_______________
R A. If the fault symptom is identified by the upper ECAM-DU warning AC BUS 1 R FAULT and one of the two CFDS messages: R GEN 1 DELTA CURRENT OTHER CHANNEL or R GEN 1 OVERCURRENT OTHER CHANNEL
R NOTE : These CFDS messages can come into view with other CFDS messages
____ R related to a delta current or an overcurrent condition of one of R the generator channels 1 or 2.
R - in the AC/DC main power center 120VU, do a check of the bus tie feeders
R for short circuits.
R (1) If there are short circuits:
R - repair them.
R (2) If there is no short circuit:
R - do a check of the feeders for a short to ground, a short circuit or
R an open circuit condition between terminals R, P, N of the BTC 1
R and the AC transfer bus (Ref. ASM 24-22/02).
R (a) If the feeders are not correct:
R - repair or replace the AC transfer busbars as necessary.
R (b) If the feeders are correct:
R - continues the trouble shooting.
