Carrier Air Cooled Chiller

[Footicus]

Hi all, I am an Aussie currently living in the UK and over working in facilities maint! :rolleyes:

I am keen as to get back in to my Trade a/c ref. Not sure if im even typing on the right forum cause im brand new to this site.

One of the sites i am currently looking after has two Carrier chillers I am after some info on them.
Model# 30RA-160-A0225-PEE

There is currently an alarm on circuit A alarm is 34 'high pressure switch not reset or cp reverse rotation?' what is cp refering to? I have reset the chiller but the fault returns so am currently running circut B only. If any one could help out that would be great

cheers

Hey
"CP" refers to compressor. The fault indicates that thers has been no change between the suction and discharge pressures once that compressor has been called for. Possibe causes is a faulty HP,(open circit); No output off board or faulty compressor contactor coil. Let us know how you go.
