E031
Error Read V
(Wrong V measure)
Measurement of the internal
voltage at the ends of the output
relay out of range. There is too
great a difference in voltage
between the input and the output
of the output relay that can be
caused by grid voltage instability.
Check the grid conditions for instabilities caused
by the switch of heavy loads or reactive loads (like
motors, welding machines, etc.). If the problem
appears repeatedly, contact ABB technical support.
E032
Error Read I
(Wrong I measure)
Measurement of the output
voltage unbalance (carried out
between the three phases) out
of range (only in three-phase
models).
This is an error inside the inverter that cannot be
checked externally. If the problem appears repeatedly,
contact ABB technical support.
E033
Undertemperature
(Under
Temperature (UT))
Alarm is triggered when internal
temperature is below low
temperature threshold.
Depending where the inverter is
located, the ambient temperature
can reach values below UT
limits. In the case in which
ambient temperature is above
the UT limits, a failure of the
temperature sensing circuitry
has occurred.
Wait for the temperatures to which the inverter is
exposed to return within operating range. If the
problem persists, contact ABB technical support.
Remember to wait for the time necessary to allow the
inverter to warm up.
E034
IGBT not ready
(IGBT not ready)
Error inside the inverter. Error inside the inverter that cannot be checked
externally. If the problem persists (after switching the
inverter off and then on again), contact ABB technical
support.
E035
Remote Off
(Awaiting remote
ON)
The inverter has been switched
off remotely (remote OFF) and
remains in waiting state for the
signal that will switch it on again
(remote ON).
Switch on the inverter remotely. If the unit does not
switch on, disable the remote on/off function and
switch the equipment off completely and then switch it
on again. If the problem persists (after re-enabling the
Remote ON/OFF function from the display), contact
ABB technical support.
