Figure 20 - Drive Reset Procedure
NOTICE In a domestic environment, this product may cause radio interference which may require
supplementary mitigation measures.
Possible Causes
Ungrounded Drive, with ground
detection parameter disabled (will
operate for 72 hours and then
fault).
Debris in pump stopping motor
from turning (locked rotor).
Pressure rising above Over
Pressure setting.
Plugged vents, fan not working,
high ambient temp, direct
sunlight, etc. Also high power
draw.
Internal drive error.
Internal drive error.
Internal drive error.
Low voltage on DC Bus caused
by heavy loading, low incoming
voltage, or unbalanced output
current.
Solution
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.
Drive tries to free debris in pump by reversing or
pulsing motor.
Drive stops and waits 1 minute, then checks
that pressure is below the Overpressure Setting
pressure. Below it restarts, if not checks again in
another minute. Can increase over-pressure value.
Improve ventilation, verify fan is working, provide
shade, etc. Verify proper system sizing.
Power cycle the drive. If Fault continues drive may
need replacement.
Power cycle the drive. Reset drive to factory
defaults. If Fault continues, drive may need
replacement
Power cycle the drive.
Check wiring for shorts, imbalance, and voltage.
Verify proper grounding.
After confirming Reset, do
not press any keys until the
Setup Guide appears.
