Fault message
Cause
What to do
Loss of phase
The system has detected
a loss of supply on at
least one phase.
−
Measure the three line voltages and
check if they are within limits.
−
Measure the line voltages (e.g.
voltmeter) and compare them with
the line voltages given by the inverter
(ESI-Manager or PQF-Link).
−
Check the AC voltage measurement
connectors (P6-1 to and P6-4) for
loose connections and component
damage.
−
Check the connections between the
auxiliary fuses and the AC voltage
measurement connectors (P6-1 to and
P6-4).
−
Check the inverter parameters
(Cf.
Chapter 8
).
Mismatch between
units
Different units in an
inverter system have
different ratings or
different connections
(e.g. 3-wire and 4-wire).
−
Recommission the inverters
−
If recommissioning does not solve the
problem, contact your ABB service
provider.
No synchronization
The system cannot
synchronize on to the
network.
The supply frequency has
changed too much or too
fast.
No/low voltage measured
during inverter
initialization.
Wrong frequency set up
−
Measure the network frequency and
its variation, and check if they are
within limits.
−
Check the phase rotation (only in case
of modification at the installation).
−
Ensure that the AC voltage is properly
measured. Do the checks discussed
for the ‘Loss of phase’ fault.
−
Verify that the frequency set up at the
commissioning stage corresponds to
the frequency of the network. (Cf.
Chapter 8
−
Reset the system by powering off and
on again.
Out of mains freq.
Limit
The system has detected
that the network
frequency is out of range.
−
Measure the network frequency and
check if it is within limits.
−
Check the phase rotation (only in case
of modification at the installation).
−
Ensure that the AC voltage is properly
measured. Do the checks discussed
for the ‘Loss of phase’ fault.
