MAINTENANCE
Troubleshooting
46
Power down, disconnect leads to the motor and power up the SubDrive:
•
If the SubDrive does not give an “open phase” fault (F5), then there is a problem with the Sub-
Drive.
•
Connect the SubDrive to a dry motor. If the motor goes through DC test and gives “underload”
fault (F1), the SubDrive is working properly.
F28
Real Time Clock Fault • Internal real time clock is not
programmed
• Real time clock battery on
display board is loose
• Real time clock battery is dead
• Ensure battery is properly inserted. If corrected, reconnect
to drive using mobile app to reset the internal clock time
• Replace battery. If replaced, reconnect to the drive using
the mobile app to reset the internal clock time
F41
Duplex Alternator
Sensor Mismatch
• Drives using the built-in Duplex
Alternator function are
configured with pressure sensor
types that do not match
• Drives using the built-in Duplex Alternator function must
have matching pressure sensor types, either a traditional
pressure sensor or a pressure transducer.
• If both drives are configured with a pressure transducer,
the transducers must both be PSI type or bar type.
F42
Duplex Alternator
Firmware Mismatch
• Drives using the built-in Duplex
Alternator function have
firmware versions that are not
matched
• Firmware version of one or both drives must be updated
to a matching firmware version using the FE Connect
mobile app.
F43
Duplex Alternator
Comm Fault
• Improper Duplex Alternator
cable connection
• Duplex Alternator cable is
damaged
• Check Duplex Alternator cable connections
• Replace Duplex Alternator cable
F44
Duplex Alternator
Unexpected Comm
• Duplex Alternator cable is
installed but Duplex Alternator
function is only configured on
one drive
• Drives are incorrectly configured
• Complete Duplex Alternator configuration on both drives
• Ensure both drives are configured properly (one drive
must be configured as Pump 1, the other drive must be
configured as Pump 2, and the Switching Interval must
match)
F45
Duplex Alternator
Demand Fault
• Both drives are running and
unable to satisfy the Primary
Setpoint pressure
• Inspect each system for proper pump operation
