Possible Cause
• Loose connection
• Defective motor or drop cable
• Wrong motor
• When fault is indicated
immediately after power-up,
short circuit caused by a shorted
connection, defective cable,
splice or motor
• High ambient temperature
• Direct sunlight
• Obstruction of airflow
• A fault was found internal to
drive
• High line voltage
• Internal voltage too high
• Broken pipe or large leak is
detected in the system
• Drive runs at full power for 10
minutes without reaching
pressure setpoint
• Large water draw, such as a
sprinkler system, does not allow
system to reach pressure
setpoint
• Motor phase currents differ by
20% or more.
• Motor is worn internally
• Motor cable resistance is not
equal
• Incorrect motor type setting
(single- or three-phase)
• Motor output cable is damaged
or exposed to water
• Phase to ground short
• Internal temperature sensor is
malfunctioning

Corrective Action

• Open reading on DC test at start.
• Check drop cable and motor resistance, tighten output
connections, repair or replace as necessary.
• Use dry motor to check drive functions. If drive runs and
exhibits an underload fault, drive is good.
• Amperage exceeded 25 amps on DC test at start or SF
amps during running
• Incorrect output wiring, phase to phase short, phase to
ground short in wiring or motor
• If fault is present after resetting and removing motor
leads, replace drive
• Drive heat sink has exceeded max rated temperature,
needs to drop below 194 °F (90 °C) to restart
• Fan blocked or inoperable, ambient above 122 °F (50 °C),
direct sunlight, air flow blocked
• Replace fan or relocate drive as necessary
• Remove debris from fan intake/exhaust
• Remove and clean optional air screen kit (if installed)
• Contact your Franklin Electric Service Personnel
• Unit may require replacement. Contact your supplier.
• Line voltage high
• Check incoming power connections and correct or tighten
if necessary
• If line voltage is stable and measured below 260 VAC and
problem persists, contact your Franklin Electric Service
Personnel
• Check system for large leak or broken pipe
• If the system contains a sprinkler system or is being used
to fill a pool or cistern, disable the Broken Pipe Detection
• Check resistance of motor cable and motor windings
• Verify motor type matched drive settings (single- or
three-phase)
• Check motor cable insulation resistance with megger
(while not connected to drive). Replace motor cable if
needed.
• Contact your Franklin Electric Service Personnel
• If problem persists, unit may require replacement. Contact
your supplier.
