I have inherited a 30gx ( tonnage??? 4 compressor) that has started to randomly trip low oil level alarms on circuit B repeatedly since the out door temp started falling.
I added some oil after recovering it back as per manual and it is still doing it.
I do know that the minimum load kit and the oil re-route kit for the comps has been recently installed back in the summer (July)
I have checked the level and it appears OK.
The oil heaters are a-OK
The machine appears to be operating normal when I have checked it and logged it out. All the numbers look OK.
I did change the loading from staged to equal as I would notice B ran a lot at minimum load and felt this may have been part of the problem.
This is a process chiller not comfort cooling.
Has anyone had any problems with the oil level switches ,the kind that screw in the bottom of the separator?
Any ideas would be appreciated.
