Hi all its been a while, hope everyone is well ?

I have a cosmotec CVE08 Panel cooling unit faulting on P1 Fault. I presume its a probe error most likely thermostat probe ?. Customer has reported that the unit is blowing the main breaker. Faulty compressor most likely as when I've split the unit condenser clogged up with paper dust (Paper Mill). Things been running hot for sometime. I've had my meter on the compressor terminals, not down to earth and the resistances on the windings are ok. I guess I'm after anymore info on this P1 fault that's holding everything off. I'd much prefer to witness the compressor tripping out with my own eyes just can't get passed this P1 Fault. Anyone with any info on cosmotec, stulz controllers. looks like a Dixell made thermostat.


Cheers

Check that there isn't a door switch keeping unit off, P1 is normally the probe alright, i suppose you could jumper out the stat to test the compressor.
