The rectifier is abnormal.
Check whether the AC input voltage exceeds the upper threshold for rectifier working
voltage. If so, locate and rectify the power supply fault and restore the power supply.
Check whether the AC input voltage is below the lower threshold for rectifier working
voltage. If so, locate and rectify the power supply fault and restore the power supply.
Check whether the ambient temperature is higher than the maximum operating
temperature of the rectifier. If so, locate and rectify the temperature control system fault.
Remove the rectifier that has generated the alarm and reinstall it after the indicator turns
off. If the alarm persists, replace the rectifier.
A rectifier has been removed.
Rectifier connections are loose.
A rectifier is faulty.
Check whether a rectifier has been removed. If so, reinstall it.
If the rectifier is in position, remove the rectifier and reinstall it.
If the alarm persists, replace the rectifier.
The DC SPD detection cable is disconnected.
The DC SPD is faulty.
Check whether the DC SPD detection cable is disconnected. If so, reconnect the cable.
If the DC SPD detection cable is reliably connected, replace the DC SPD.
Check whether the battery is overloaded or aged.
Check whether the test end time and test end voltage are correctly set.
