Fault Code
Meaning
Possible Cause
Solution
VFD DC bus voltage too
high
The operator’s AC input
voltage is too high or too
much noise exists on the
AC line.
Measure AC input voltage. If
it is too high, lower the
incoming voltage. Consult
with a qualified technician
and consider installing a
buck transformer to lower
the voltage. If noise is the
issue, consider an EMI filter
on the input lines.
VFD DC bus voltage too
low
The operator’s AC input
voltage is too low or the
wire size is too small for
the distance being
covered from the breaker
box to the operator.
Measure AC input voltage. If
it is too low, raise the
voltage level. Consult with a
qualified technician to learn
which options will raise the
voltage sufficiently to allow
for proper operator function.
Excessive power load
on VFD
Pressure Relief Valve is
set too high. This may
occur to compensate for a
binding gate or an
overweight gate. Brake
valves could also be too
tight
.
Check gate for binding
issues or an overweight
installation. Make sure brake
valves are set to mid-range
and the pressure relief valve
setting is about 1100psi or
less.
Excessive
instantaneous load on
VFD
NOTE:
Cannot reset the
fault code until 10
seconds elapse after
the fault occurs.

or
Excessive heat in VFD
Lack of air ventilation
around VFD. Excessive
load on VFD.
Perform the same resolution
steps in
. And then,
check and clear any
constriction around the front
and back cooling vents on
the gray control box. Make
sure air ventilation pathways
are clear around the VFD
inside the control box.
