The time delay allows the compressor adequate time to establish oil pressure on start up and avoids nuisance shutdowns on pressure drop of short duration during the run cycle. · Maximum application flexibility is assured by providing an adjustable differential pressure switch which can be adjusted to the compressor’s minimum required oil pressure needs and an adjustable time delay which allows you to select the length of time the compressor runs below the minimum pressure before shutdown. The minimum pressure setting and time delay values specified …
