Hvac Johnson Controls Lube Oil Controls | Lube Oil Control For Copland Compressors

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.
