range, and frequency range are
correctly set.
3. Check that the bypass cables and
circuit breakers are correctly
connected.
1. Check that the output and bypass
input circuit breakers on each rack
are ON.
2. Check that bypass input and output
power cables on each rack meet
the length requirements.
3. Rectify any bypass SCR open-
circuit.
1. Check that the bypass output
frequency does not change fast.
2. Check that the Output freq. track
rate is properly set.
1. Check the dual bus connector.
2. Check the parameter settings.
3. The master BSC system is not
supplying power.
1. Shut down the inverter and then
close the maintenance circuit
breaker.
2. After maintenance, open the
maintenance circuit breaker and
then start the inverter.
Wait until the inverter self-check is
complete.
