102 POWER FAILURE DETECTED BY DSU

[michelepin]

Hi all,

i've got this error on my MD110 BC11 REL 13:

CLASS: 4
102 POWER FAILURE DETECTED BY DSU
DATE TIME ALP NOIF EQU INF1 INF2
25AUG17 08:31:45 1 1 005-0-**-** 0 4

Looking on further posts, i've tried removing all TLU29 boards *but* alarm still there. At the moment, on the LIM there are PU4DC, LPU5, LSU, DSU and GJUL4.

Any help really appreciated.

Michele

102
Power failure detected by DSU

ADD INFO 1:
0 - 3 = States DSU


ADD INFO 2:
0 = DSU board is missing -5V
1 = DSU board is missing +12V
2 = DSU board is missing -12V
3 = DSU board is missing -48V
4 = DSU board is missing RGA (ringing voltage)

so your REU card or RG5DC card in mag 0 is kaput

Thanks for your kindly help. But i've not REU nor RG5DC in this lim. Maybe the PU4DC ? And can i replace the PUA4DC with a RG5DC ?
