FD113-ZUK Oil Pressure Safety

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.
