"Extracta" P&'roleum Pump <br /> imp/Motor Assembly <br /> A) The permanent split capacitor motor gives you the option (To determine position of overload,see procedure below.) <br /> of using a control box or direct wiring. <br /> (1) Overload protector opens at approximately this tem- <br /> perature and stops motors. <br /> B} An on-winding thermal over-current protector prevents <br /> premature motor failure from overheating. ( }2 Motor is continuous duty rated.Temperature rises to <br /> approximately 120°F and holds. <br /> Ambient temperature overload can occur as follows: <br /> (1) 205°F=Overload TemperatureUnit Is cooled and lubricated by the prod- <br /> Overload protector opens at approximately this tem- + uct It pumps.Approximately 10%of maxl- <br /> perature and stops the motor.

Attempts to exceed these limits will result in <br /> motor cut-off. If high amperage draw is present, it is overheating. <br /> probably not ambient temperature overload.) <br /> Seepage 14 for Troubleshooting of the Pump/Motor Assembly. <br /> Per Figure 1, when the inherent overload (on-winding Pin and lead arrangement on plug to motor connection. <br /> thermal over-current protector) is closed, resistance <br /> readingswill be per chart below.If the inherent overload <br /> is open,readings between black&yellow or red&yellow <br /> will indicate an open circuit.
