Rectifier Fault
NOTE!
If a rectifier is pulled out or there is a faulty rectifier, the user should reset the controller. Or else the batteries
cannot be boost charged.
Handling indicator fault
The symptoms of usual rectifier faults include: power indicator (green) off, protection indicator (yellow) on, protection indicator
flash, alarm indicator (red) on and alarm indicator flash.
The indicators positions are shown in Figure 4.5.

No alarm
No input or output voltage
Ensure having input and output voltage

temperature
Main causes of
overheat protection
for rectifier
Fan is blocked
Remove the object which blocks the fan
operation
The vent duct is obstructed: there are
some blockages at air intake or air outlet
Remove the blockage at air intake and air outlet
High temperature or pyrotoxin is near to
the air intake of rectifier
Decrease ambient temperature or remove the
pyrotoxin
The rectifier isn’t absolutely inserted into
the subrack
Reinsert rectifier
Rectifier protection
No current sharing
Check the rectifier communication whether
normal or not. If not, continue to check the
connection of communication lines. Replace the
fault rectifier when it works normally
PFC output overvoltage protection
Change the position of the abnormal and normal
rectifiers. Replace the abnormal rectifier if it
cannot work normally all the same
AC input voltage exceeding the normal range
Ensure the AC input voltage whether in normal
range or not
