Air System Troubleshooting Guide
system is:
WE SUGGEST YOU CHECK THIS:
A. Low line voltage. Power consumption is a function of line voltage and amperage draw (P=IxE). If the facility's line voltage dips below required levels, the pump and motor may draw excessive amps, resulting in excessive heat and motor trip out.
B. The motor starter could have a defective contactor. Such a situation would not allow the contactor to handle the proper level of amperage, causing it to interrupt power to the motor prematurely.
C. There could be a loose wire in the main power feed or the circuit to the pump motor. Loose or inadequate wire connections will cause excessive resistance and subsequent high amp draw.
D. A weak motor. If the pump's motor is old, it could become weak due to numerous occasions of heating and cooling. The motor may need to be replaced.
