for differential oil pressure the controls look at the difference between the econmizer transducer and the oil pressure transducer .....the economizer transducer is the highest low pressure in the compressor and is higher than the suction pressure ...discharge pressure drives the oil but does not factor in the oil diff calculation .... Filter diff calc yes...oil press diff ...noooooo...

the manual used to and may still have listed the Einstein equation the controls use to prove proper oil pressure . it can be very confusing.
If I'm wrong I'll quit the trade and go be a strip club DJ
If i make no sense I'll sit out in the sun again tomorrow and cook my brain some more then come back for seconds....
