EF0
Opt External Flt
Communication Option Card External Fault An external fault condition exists.
Check for an external condition.
Verify the parameters.
Verify communication signal.
EF3
Ext Fault S3
External Fault at Terminal S3
An external fault condition exists
connected to a multi-function
digital input.
Eliminate the cause of an external fault
condition.
EF4

External Fault at Terminal S6
EF7
Ext Fault S7
External Fault at Terminal S7
Remove the fault from a multi-function
digital input.
FbL
Feedback Loss
PI Feedback Loss
This fault occurs when PI Feedback Loss
Detection is programmed to fault (b5-12 = 2) and
the PI Feedback < PI Feedback Loss Detection
Level (b5-13) for the PI Feedback Loss Detection
Time (b5-14).
PI Feedback source (e.g.
transducer, sensor, building
automation signal) is not installed
correctly or is not working.
Verify iQpump is programmed to receive
the PI Feedback source signal.
Check to ensure the PI Feedback source
is installed and working properly.
GF
Ground Fault
Output Ground Fault
iQpump output grounding current has exceeded
50 % of the iQpump rated output current.
Motor lead is shorted to ground,
DCCT defective.
Remove the motor and run the iQpump
without the motor.
Check the motor for a phase-to-ground
short.
Check the output current with a clamp
on meter to verify the DCCT reading.
