Copeland 940 0001 80 Relay Kit Freon ECM Efficiency: Significantly lowers power ECM Efficiency: Significantly lowers power consumption compared to older PSC technology Technicians should check for continuity across the coil and verify that the contacts close securely when energized The pickup rating refers to the specific voltage (expressed via current equivalent in internal sensing) at which the relay contacts open to drop the start capacitor out of the circuit once the motor reaches approximately 75 80% of its synchronous speed or the start capacitor showing signs of swelling or venting due to staying in the circuit too long
