Temperature Pressure Controls
TheFD113OilPressureSafetyControlsensestheeffectiveoil
pressure on pressure lubricate compressors. If inadequate oil
pressure exists, a time delay is energized. If the oil pressure
does not recover to safe levels within the time delay setting, the
compressor is shut down. 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exibility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 electronic time delay which allows the selection of the
length of time the compressor runs below the minimum pressure
before shutdown. The minimum pressure setting and time delay
valuesspeciedbythecompressormanufacturershouldbeused
wheninstallingtheFD113control.
