The P545 Series Electronic Lube Oil Control is designed for use on refrigeration compressors equipped with an oil pump that accepts a single-point differential pressure switch. The P400 switch continuously monitors net lube oil pressure and the P545 control locks out the compressor if lube oil pressure falls below the manufacturer's recommended net pressure for longer than the recommended lube oil time delay. Front-mount Light-Emitting Diodes (LEDs) indicate the status of the lubrication system, and a user-selectable, minimum-off time delay can be set to minimize compressor short cycling. A Johnson Controls/PENN® R310AD Current Sensing Switch, sold separately, may be used to disable the P545 control lockout circuit during abnormal compressor shutdowns.

Features:
  • Single-Pole Double-Throw (SPDT) relay contacts for liquid line solenoid and alarm applications allow liquid line solenoid to be closed if the P545 control shuts off the compressor due to low oil pressure and provides alarm indication, including circuits that use neon lights
  • relay contact output for compressor provides reliable, long-lasting operation
  • built-in test circuit verifies proper control operation quickly, without additional tools or equipment
  • improved noise immunity exceeds immunity requirements of UL 991 for transient overvoltage: IEC 61000-4-3 for radiated Radio Frequency (RF) and IEC 61000-4-6 for RF-induced conducted disturbances
  • jumper-selectable anti-short cycle time delays provide for a wide range of anti-short cycle strategies that meet most equipment requirements- the anti-short cycle delay feature may allow for the elimination of an external short-cycle timer
  • user-friendly display panel displays the status of the compressor lubrication system continuously
  • backwards compatibility allows easy replacement of existing electronic lube oil controls
