[oupak]

Hi

i have aproblem with a hiross chiller[mod no:SBH032] with 2 refrigerant circuits both having 2 compresors each..when the first circuit starts,it only run for 45 seconds then trips on OIL PRESSURE SWITCH but it does not have an oil pressure switch neither on the electrical circuit nor on the chiller itself...
the alarm that pops up on the screen says 032 and oi1 with a set word below it..
YOUR HELP WILL BE MUCH APPRECIATED

Have you checked that the chiller is set up for Scroll compressors? it may be set up for Screw compressors and looking for an oil level or pressure switch.

the compressor values are read only values cant be adjasted...i will have to replace the alarm card on the unit..
its the one generating the alarm..thank for the input ALLROUNDER...
