If the load side conductors of a compressor with oil failure control are disconnected, will the compressor lock out?

When the load side conductors of a compressor with oil failure control are disconnected, the compressor will lock out to protect itself from damage. This safety mechanism is designed to prevent the compressor from running without adequate lubrication, which could occur if the compressor has lost its oil supply or if there is a system fault.

The oil failure control is a critical safety feature that continuously monitors the oil pressure within the compressor. If the oil pressure drops below a predetermined level, the control system detects this state and initiates a lockout condition to stop the compressor operation. The primary aim of this lockout is to prevent overheating, excessive wear, or catastrophic failure of the compressor due to insufficient lubrication.

When the load side conductors are disconnected, the compressor receives no power to operate, which aligns with the lockout condition as the compressor cannot function without necessary electrical supply and adequate oil pressure. Hence, the compressor will indeed lockout under these circumstances, affirming the correctness of the chosen answer. This built-in protection mechanism underscores the importance of oil failure controls in maintaining the longevity and reliability of compressor systems.
