Possible Causes
•
When fault is indicated imme-
diately after power-up, short
circuit caused by a shorted
connection, defective cable,
splice, or motor
•
High ambient temperature
•
Direct sunlight
•
Obstruction of airflow channel
•
Measured pressure exceeds
setting
•
A fault was found internal to
drive
•
High line voltage
•
Internal voltage too high
•
Broken pipe or large leak is de-
tected in the system
•
Drive runs at full power for 10
minutes without reaching pres-
sure setpoint
•
Large water draw, such as a
sprinkler system, does not al-
low system to reach pressure
setpoint
•
Broken Pipe Pressure setting is
higher than the active Setpoint
pressure setting
•
Motor phase currents differ by
20% or more.
•
Motor is worn internally
•
Motor cable resistance is not
equal
•
Cable connection between
Control Board and Power
Board is loose or disconnected
•
Internal circuit failure
Corrective Action
•
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
•
The drive has exceeded max rated temperature, needs to
drop below 167 °F (75 °C) to restart
•
Fans blocked or inoperable, ambient above 104 °F (40 °C),
direct sunlight, air flow channel blocked
•
Replace fans or fan module; or relocate drive as necessary
•
Remove debris from fan intake/exhaust
•
Troubleshoot system to locate reason for high pressure
•
Contact your Franklin Electric Service Personnel
•
Unit may require replacement. If problem persists, note the
sub-fault number on the display before contacting the FE
Service Personnel.
•
Line voltage high, greater than approximately:
- 290 VAC (normal 230 operating range = 190 to 260)
- 600 VAC (normal 460 operating range = 380 to 520)
•
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
•
Adjust the Broken Pipe Pressure setting to a value lower than
any active Setpoint pressure settings.
•
Check resistance of motor cable and motor windings.
•
Phase imbalance and loss of phase may indicate similar
issues.
•
Check cable connection between Control Board and Power
Board. The cable connection on the control board is located
on the back side of the control board.
•
If problem persists, unit may require replacement. Contact
your supplier.
