Potential relay start capacitor wiring diagram. The start capacitor is removed from the circuit by a relay called the potential relay. Potential relay wiring diagram compressor potential relay wiring diagram copeland potential relay wiring diagram mars potential relay wiring diagram every electrical arrangement consists of various distinct components. This is the wiring of the potential relay. Wiring diagram also provides beneficial recommendations for tasks which may need some extra equipment. The start capacitor gives the motors windings an electric boost during the start up phase. I show the coil and how to measure resistance values for diagnosing the coil or contactor tabs while using a multimeter.
A start capacitor kit contains a start capacitor relay and wires. Potential relay wiring diagramac capacitor wiring relay wiring with starting and running capacitor potentialrelaywiring voltagerelaywiring relaywir. When the back emf has built up to a high enough value referred to as pick up voltage the contacts between terminals 1 and 2 will be picked up opened. Understanding basic electrical. The relay disconnects the start capacitor from the motors electrical circuit once the motor has reached operational speed. The purpose of this booklet is to dem onstrate how to wire a.
This guide even consists of recommendations for additional provides that you might need to be able to complete your tasks. I explain how it controls the start capacitor after the compressor starts. Test the start relay overload capacitor ptc. It is very easy to miswire a compressor but the results can be deadly. Each part should be set and connected with different parts in particular way. This video is part of the heating and cooling series of training videos made to accompany my websites.
Explaining the differences between current relays and potential relays and their role in starting compressors. Potential relay start capacitor run motor with capacitor diagram potential relay wiring diagram. The back emf voltage generated across the start winding causes a small current to flow in the start winding and potential relay coil because they are in the same circuit. Accordance with the position of the capacitors and relay shown on the wiring diagram.
