Possible Causes
• When fault is indicated immediately
after power-up, short circuit caused by a
shorted connection, defective cable,
splice, or motor
• 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
• High ambient temperature
• Direct sunlight
• Obstruction of airflow channel
• Fan blocked or inoperable, ambient
above 122 °F (50 °C)
• 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 ex-
posed to water
• Phase to ground short
• Internal temperature sensor is
malfunctioning
• Cable connection between Control Board
and Power Board is loose or
disconnected
• Internal circuit failure
Corrective Action
• Check wiring and fix as necessary
• If fault is present after resetting and removing mo-
tor leads, replace drive
• Wait until drive temperature drops below 194 °F (90
°C) to restart
• Replace fans or fan module; 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.
• Check incoming power connections and correct or
tighten terminals 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.
• Check cable connection between Display/Wi-Fi
Board and Main Control Board.
• If problem persists, unit may require replacement.
Contact your supplier.
