C Alarm List
Solution
1. Reduce the load.
2. Decrease the configured
number of redundant
modules.
1. Check the bypass input
voltage and frequency.
2. Check that the rated
voltage, rated frequency,
ECO bypass voltage 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.
