Description
The rectifier module works in the normal
state.
This LED is off when the red LED is on or
the yellow LED is on which is not caused by
the output overcurrent.
An alarm has been generated for the rectifier
module. The possible causes are as follows:
l The AC power is cut off or no AC power
is supplied.
l Over-temperature protection is enabled.
l Primary protection is enabled.
Specifically, the rectifier module
automatic protection function is enabled
due to a high voltage on the AC input
end.
l Overcurrent protection is enabled.
Specifically, the rectifier module
automatic protection function is enabled
because the DC output current of the
rectifier module exceeds the current
range supported by the rectifier module.
The communication of the rectifier module
is interrupted.
The rectifier module works in the normal
state.
The rectifier module is faulty. The possible
causes are as follows:
l The AC power supply is faulty.
l The output voltage is 0 V.
l The fan is faulty.
l The rectifier module output is short-
circuited or does not work.
