A i rf low Path T h r o u ~ hCyl inder Back Table of Contents Theory of Operation - Continued The motor-pump compressor heads are integrated into a single cast-iron case for reasons of noise control and simplicity. Each motor-compressor capacitor/relay box includes a starting capacitor and, on 1 hp. models, a running capacitor connected to the motor start and main windings as shown: potential Relay and Start/Run Cavacitors START 2 PROTECTOR UNE The potential relay, normally closed, opens to disconnect the start winding and capacitor when back-EMF generated in the start winding rises to a value associated with normal running speed. Each motor type requires slightly different potential relays and start/run capacitors. These are only available as a complete capacitor/relay assembly, as shown on parts breakdown. On the Start and Run capacitors, the "identified" terminal is the one connected to the outer foil. This terminal has a higher probability of shorting to the capacitor can, and is therefore always connected to the line rather than to higherEMF parts of the circuit, such as the start winding. Starting capacitors include a high-resistance "bleedw resistor installed directly across the capacitor terminals to minimize relay point welds and/or service personnel shock hazard.
