Package chiller tripping on low pressure latch fault. actual suction while monitoring is 60Psig and display is reading about the same. Discharge pressure running around 225-250.
2nd stage runs like a champ after stage 1 trips out, so ive ruled out a flow issue...water temp running at 47 degrees. flow switch is working as it should....At this point im looking for ideas whether u think its the pressure switch near the barrel going bad or if exv is closing/not opening as it should.
