Troubleshooting

Fault Possible Causes Solution
Open Transducer
Intermittent connection
Check all transducer wires are securely
connected or for damaged cable insulation.
Open Connection
Check for proper wiring of all transducer wires
and verify cable connector securely attached to
transducer.
Drive cannot read transducer signal
Check electrical system for ground loops or no
ground connection.
Transducer wires crossed Check red is in AI+ and black is in AI-.
Possible failed transducer
Check linearity of transducer; see
Troubleshooting Guide for more information.
Shorted Transducer
Short in transducer wires
Check for shorted transducer wire or damaged
insulation.
Possible failed transducer
Check linearity of transducer; see
Troubleshooting Guide for more information.
Over Temperature Excessive heating in drive
Check ambient temperature is not above 50°C
(122°F).
Check for inoperable or unobstructed fan.
Check vents are not obstructed.
Excessive Runtime
Leak detected Check for leaks in pipe system.
Application calls for long run times
Extend Excessive Runtime Hours limitation.
Disable Excessive Runtime Fault.
Internal Fault Internal voltages are out of range
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.
Hardware Fault Internal hardware failure
Fault Reset can be pressed to clear fault. Then
try to operate pump. If fault continues Drive
may need replacement.
External Fault
The external device detected fault
condition and closed the I1 or I2 input
Check external device.
Low Amps
Under-sized pump
Increase Minimum Speed to 35 Hz.
Low current draw from pump
Thermal protector open in motor (3
wire)
Wait 20 minutes then restart pump.
Missing motor phase Check all motor connections at the Drive.
Warning Possible Causes Solution
Warning LED
flashing
Ungrounded Drive, with ground
detection parameter disabled (will
operate for 72 hours and then fault).
Verify ground wire is connected on both
incoming voltage side and motor side of Drive.
With the power disconnected, use an
ohmmeter to verify which pipe the Drive’s
transducer is connected to. Also verify that the
input ground wire is at the same potential, e.g.,
has approximately the same ohm reading.
Verify the input ground is connected all the way
back to electrical panel.
Jam Warning
Debris in pump stopping motor from
turning (locked rotor).
Drive tries to free debris in pump by reversing
or pulsing motor.
Over Pressure
Warning
Pressure rising above Over Pressure
setting.
Drive stops and waits 1 minute, then checks
that pressure is below the Setpoint pressure.
Below it restarts, if not checks again in another
minute. Can increase over-pressure value.
