A compressor with Motor.XXX, MULTILIn alarmed on high stator temperature, DCS recorded the Multilin alarm and also Low Lube oil pressure
even while the aux pump continues to run. what i know so far is as follows
highest temperature is 126 DEGC
Alarm trip point is 125 DEGC
Motor nameplate design temperature is 43DEGC
The ambient temp at the time was 108DEGC
Alarm would not reset because it was above Alarm set point
Next day alarms have been cleared and alarms were on three RTDs?
i am looking at verifying all set points on the relay and looking at the aux pump
what do you suggest be done as a proper procedure to correct this?
Thanks
