P545NCB-82C Johnson Controls LUBE OIL Control

Overview

The Johnson Controls P545NCB-82C is an electronic lube oil control designed for refrigeration compressors equipped with an oil pump, specifically engineered for Carlyle compressors. It continuously monitors net lube oil pressure and de-energizes the compressor if the pressure drops below the recommended threshold for longer than the designated time delay, preventing compressor wear and damage.

• Continuous monitoring of net lube oil pressure with automatic compressor lockout
• Front-mounted LEDs providing real-time lubrication system status indications
• User-selectable anti-short cycle time delays to minimize compressor short cycling
• Built-in test circuit for quick verification of proper control operation
• SPDT relay contacts supporting liquid line solenoid and alarm applications
