• Over current due to trapped
debris in pump
• Incorrect HP setting
• Amperage exceeded 72 amps on
DC test or while running
• Incorrect wiring
• Phase to phase short circuit
• Phase to ground short circuit
• High ambient temperature
• High internal drive temperature
• Direct sunlight
• Obstruction of airflow
• A fault was detected internal to
the drive
• Drive runs at full power for 10
minutes without reaching
pressure setpoint
• Broken pipe or large leak is
detected in the system
• Large water draw, such as a
sprinkler system or filling a pool,
does not allow system to reach
pressure setpoint
Corrective Action
• Verify wire connections at motor terminal block
• Disconnect motor leads and use megger to check motor
insulation resistance; if low reading, replace motor
• If fault is still present after resetting the drive and removing
motor leads, replace drive
• Check air screen for debris, clean as necessary
• Check for proper fan operation, replace as necessary
• Internal drive temperature must be below 80 °C before
starting the motor, or below 70 °C before starting a motor
after a Locked Pump fault.
• Refer to drive placement recommendations.
• Contact your Franklin Electric Service Personnel
• Unit may require replacement. Contact your supplier.
• Verify settings per instruction
• Check system for large leak or broken pipe
