Betapack 2 - CH1+2 Full On

[nickb512]

Hi All

 

I have a Betapack 2 with a strange issue which seems to have confused quite a few people. Channels 1 + 2 are stuck on full.

 

The background to the problem is the dimmer had been installed a bit too close to a DB, which was blocking the screw holes at the back (for the top cover). At some point somebody has removed the top cover (either as part of the installation or afterwards) and not put these screws back, leaving the top cover only attached at the front. Anyway about a year ago something was put ontop of the dimmer which caused the top panel to fall down at the back and the metal of the casing shorted on the live input at the top of the pack.

 

Since then channels 1 + 2 have been stuck on!

 

So far have tried the following:

- replaced triacs and swapped the triacs with other channels.

- checked preheat settings etc

- swapped entire control pcb with another working betapack

- replaced transformer on left side of pcb (as suggested by support)

 

Im sure i tried some other bits but cant think of them right now.

 

Either way, not a huge problem if it cant be fixed, but if anybody has any ideas i would love to hear them!

 

Thanks
