Demand Fault
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.

Possible Cause
programmed
• Real time clock battery on
display board is loose
• Real time clock battery is dead
• 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 have
firmware versions that are not
matched
• Improper Duplex Alternator
cable connection
• Duplex Alternator cable is
damaged
• Duplex Alternator cable is
installed but Duplex Alternator
function is only configured on
one drive
• Drives are incorrectly configured
• Both drives are running and
unable to satisfy the Primary
Setpoint pressure
Corrective Action
• 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
• 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.
• Firmware version of one or both drives must be updated
to a matching firmware version using the FE Connect
mobile app.
• Check Duplex Alternator cable connections
• Replace Duplex Alternator cable
• 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)
• Inspect each system for proper pump operation
