Need to change QPC82 Powr convr crds.

Need to change QPC82 Powr convr crds.

Need to change QPC82 Powr convr crds.

(OP)
My meridian XT QPC84 Power monitor card shows a 30v warning light. After measuring the voltage on all the QPC82 Powr Converter Cards (all in the same shelf as the QPC84), both card show +13v @ the 15v pin and -17v @ the -15v pin . Does anyone know the steps involved in changing out this cards: (QPC 82).  Thanks in Advance.

RE: Need to change QPC82 Powr convr crds.

I DON'T HAVE ANY MANUALS ANY LONGER BUT SEEMS TO ME THERE IS A SWITCH
ON THE POWER DISTRIBUTION PANEL.  IT HAS BREAKER AND FUSES YOU NEED TO
FIND THE BREAKER ASSOCIATED WITH THE CARD YOU ARE CHANGING TURN IT OFF
AND CHANGE THE CARD AND RESET THE BREAKER.  THIS WILL PROBABALY TAKE DOWN SHELVES OR CARD THESE 30 CONVERTERS POWER SO IT SHOULD BE DONE DURING OFF TRAFFIC TIMES.  IT IS ALSO A POSSIBILITY IT IS YOUR QPC84 CARD THAT MONITORS THESE VOLTAGES NOT THE 30 VOLT CONVERTER.  I WOULD TRY IT FIRST.  IT HAS DIP SWITCHES ON IT MAKE SURE THE CARD IS THE SAME VINTAGE AND THE DIP SWITCHES ARE SET THE SAME.  IT HAS A DISABLE SWITCH ON THE FRONT. DISABLE IT BEFORE YOU REMOVE IT.  ALSO MAKE SURE IT IS DISABLED BEFORE YOU PLUG IT IN THEN ENABLE IT.  HOPE THIS HELPS AND MY MEMORY IS CORRECT.
