B Alarm List
Solution
inverter relay is closed, close
the bypass input circuit
breaker 10 seconds later.
1. Check that there is no
overload.
2. Check that the module power
is not derated due to a fan
fault.
3. Check whether the power grid
has a large asymmetric load.
4. Check whether the output is
grounded.
5. Check whether the peak load
ratio exceeds the upper limit.
6. If the alarm persists, replace
the power module.
1. Check the load.
2. If the load is normal, replace
the power module.
1. Check that there is no
overload.
2. Check that the module power
is not derated due to a fan
fault.
3. If the alarm persists, replace
the power module.
1. Check the bypass fan and air
channel. If the fan is faulty,
replace it.
2. Check that the ambient
temperature has not exceeded
40° C.
3. Check that there is no
overload.
