signal
Transducer wires crossed
Possible failed transducer
Short in transducer wires
Possible failed transducer
Excessive heating in drive
Leak detected
Application calls for long run
times
Internal voltages are out of range
Internal hardware failure
The external device detected fault
condition and closed the I1 or
I2 input
Motor not wired correctly to drive
Thermal protector open in 1-phase
motor
Missing motor phase
Solution
Check all transducer wires are securely connected
or for damaged cable insulation.
Check for proper wiring of all transducer wires
and verify cable connector securely attached to
transducer.
Check electrical system for ground loops or no
ground connection.
Check red is in AI+ and black is in AI-.
Check linearity of transducer.
Check for shorted transducer wire or damaged
insulation.
Check linearity of transducer.
Check ambient temperature is not above 50°C
(122°F).
Check for inoperable or unobstructed fan.
Check vents are not obstructed.
Check for leaks in pipe system.
Extend Excessive Runtime Hours limitation.
Disable Excessive Runtime Fault.
Drive will auto reset and attempt to clear fault.
Fault Reset can be pressed to clear fault as well.
Then try to operate pump. If fault continues Drive
may need replacement.
