Comms alarm on Scroll MK II Pack

Hi Guys,

I have a problem with an alarm on compressor LT2 on a Scroll MK II Refrigeration Pack. The front end panel is telling me that I have a comms alarm on the compressor, I have checked all electrical connections, i quickly pressed the contactor to make sure the compressor works and there are no problems with it. Could the problem be with one of the thermisters on the discharge? All oil levels are correct and there is no alarm indication on the Elm moniter and nothing happens when I try to reset the alarm.

Any help on this is appriciated! As Ive said im my previous posts Im new to the supermaket/retail side and its pretty daugnting!! I bought a book on it and hopefully I can be with you guys helping others in the future!!

Thanks!!!

If you have a comms alarm it generally indicates a communication fault - if you have identical controllers try to swap them and check connections/cables
