Hello everyone,

 

Hope you're getting along ok in these difficult times.

 

I've been getting what seems to me to be an odd PSU fault for the last week (G244 with 2 x powered RIOs).  In the unset state the keypad will randomly go into the alert state with the dreaded beep. On inputing the master code the screen shows the following fault:

 

AC Fail PSU 103

 

which I assumed to be the PSU on the second RIO unit (103=3rd PSU after main panel?) but now not so sure.  On opening all 3 panels all would appear to be fine inside with the red LED in the RIO units flashing at the correct rate.  

 

I installed the main panel back in 2011 which has been flawless and the 2 RIOs early this year and they've both been fine too.

 

Any ideas from the Galaxy experts here?

 

Many thanks,

Richard

Have you got a dog?

If its reporting ac fail on 103 I'd start there. Measure ac side and dc side. Asuming that's all OK id assume a smart PSU failure 

Could be the smart RIO PSU card (one on the right) if its the newer switch mode PSU, seen a few with a dodgy capacitor.

no.

Thanks for the suggestions (and Mr Happy's inimitable input ;-)). I'll be able to get a tester on it tomorrow and see what it says. Cheers Nova for the heads up on the cards. 

We have had a few of the new switch mode power supplies fail over the last couple of years.

causing no end of problems.
