SYSTEM TRIP CODE TROUBLESHOOTING
Should an application or system problem occur, built-in diagnostics will protect the system . The red “FAULT” light on the front
of the controller will flash and a fault condition will be shown on the display . In some cases, the system will shut itself off until
corrective action has been taken . Fault codes and the recommended corrective action for each are listed in the following
table . To view the trip codes in the recent trip log, press and hold the UP & DOWN keys at the same time for 1 second . The
log will show the last 20 trips as well as the time in days, hours & minutes since the trip occurred . (Note: the trip time will only
increment while the drive has power .) If no trips have been recorded, “No Fault” will be displayed in the log .
Fault
Possible Causes
Corrective Action
KEY:
APPLIES ONLY TO TRANSDUCER
APPLIES ONLY TO PRESSURE SWITCH
APPLIES TO EITHER OPTION
Short circuit
Shorted motor cables
Check motor wires and drop cable for shorts or bad connections
Shorted motor
Replace motor
Damaged wire insulation
Check drop cable for insulation damage
Internal hardware short
If motor is disconnected and the fault is present when reset, replace drive .
Locked Rotor
Motor/pump misaligned
Verify Pump is mounted flush on motor mounting flange .
Bound pump
Check for debris n pump
Transducer Found
(Switch Control)
Drive set for Switch control, but a
transducer signal was detected.
Change drive control choice from Switch to Transducer in Control
Choice menu
Shorted Transducer
(Transducer Control)
Drive has detected a short circuit between
S1 & S2 terminals
Internal short of transducer . Replace transducer .
Switch is hooked up between S1 & S2
Replace switch with transducer .
Open Transducer
(Transducer Control)
Transducer lead not connected properly to
transducer (or cut)
Check transducer lead connection and/or replace transducer lead wire .
Loose connection on terminals S1 & S2
Check transducer lead connection at drive terminals S1 & S2
Transducer lead wire backwards at S1 & S2
terminals
Switch transducer leads at S1 & S2
Transducer failed as an open circuit
Replace transducer
Deadhead
(Switch control)
Pump running against a closed discharge. Make sure that there is not a valve closed or obstruction
between the pump and pressure switch
Damaged or clogged pressure switch
Check continuity across switch contacts without wire connected
and replace and/or clean pressure port.
Deadhead sensitivity incorrect
Adjust deadhead sensitivity in Underload Protection menu
Deadhead
(Transducer Control)
Pump running against a closed discharge .
Make sure that there is not a valve closed or obstruction
between the pump and pressure transducer
Deadhead sensitivity incorrect
Adjust deadhead sensitivity in Underload Protection menu
Clogged pressure transducer
Check transducer for pressure port and clean
Damaged or inoperative transducer
Replace transducer
Low PSI
(Transducer Control)
Pipe has not filled
Reset pipe fill mode in Menu #10 Control Settings and increase fill time if
necessary .
Valve closed between pump & transducer
Open valve between pump & transducer .
Clogged Pressure transducer
Check transducer for pressure port & clean
Damaged or inoperative transducer
Replace transducer
Dry Well
Over pumped/dry well
Wait for well to recover and automatic restart timer to time out
Blocked pump screen
Clear pump screen
Broken pump shaft
Replace pump shaft (or pump)
Worn pump
Replace pump
Under Voltage
Low line voltage
Check line voltage Report low voltage to the power company
Power was removed from Drive
Check voltage is present on all input lines & connections secure
(Color) Leg Open
Loose connection
Check connections on drive motor terminals for leg specified
Defective splice
Check all splice connections on drop cable for leg specified
Defective cable
Check continuity of drop cable for leg specified
Open motor winding
Replace motor
Overheated
Excessive heating of Drive
Check that the ambient temperature is not above 125°F
Check for obstructed or inoperable fan
Check for blocked vents
Broken Pipe
Drive has been running without going into
standby mode for set time
Check for broken or leaking pipe and repair as necessary
Application calls for long run time
Increase broken pipe run time in Advanced Feature menu
Turn off Broke Pipe protection in Advanced Feature menu
External Trip
Contacts closed on "Alarm In" terminals
Check condition of switch wired into "Alarm In" terminals
