Possible Cause
• DIP SW2 position 1 is incorrectly
set
• Pressure transducer is incorrectly
wired
• Pressure transducer signal is
outside the expected range
• Pressure transducer is
disconnected
• Pressure transducer is damaged
or failed
Possible Cause
• No supply voltage present
• Pressure sensor circuit
• Fault detected
• Underload
• Power surge
• Bad component
• Internal Fault
• Loose switch or cable
connection
• Gulping water at pump inlet
• Motor may be running
backwards
• Verify DIP SW2 position 1 is in the XDCR (up) position if
using a transducer
• Inspect transducer wiring connections
• Replace transducer
Corrective Action
• If correct voltage is present, replace drive
• Verify water pressure is below system set point
• Refer to "Diagnostic Fault Codes" on page
• Repair or replace the required foot valve for pump applications
with suction lift
• Turn off power to clear the fault and verify input voltage.
• If repetitive, replace drive
• If frequency max with low amps, check for closed valve or stuck
check valve
• If frequency max with high amps, check for hole in pipe
• If frequency max with erratic amps, check pump operation,
dragging impellers
• This is not a drive problem; check all connections, disconnect
power, allow well to recover and retry
• Confirm max amps setting is set correctly
• Confirm Underload Sensitivity is set correctly
• Verify that motor connections are correct
