4.2.19 Rect Fault

Possible Causes



Rectifier connections are loose.



A rectifier is faulty.

Measures

1.

Check the Fault indicator on the rectifier panel. If it is steady red, remove the rectifier,
and then reinstall it after the indicator turns off.

2.

If the alarm persists, replace the rectifier.

4.2.20 Rect Protection

Possible Causes



The rectifier input voltage is too high.



The rectifier input voltage is too low.



The ambient temperature is too high.



The rectifier is abnormal.

Measures

1.

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.

2.

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.

3.

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.

4.

Remove the rectifier that has generated the alarm and reinstall it after the indicator turns
off. If the alarm persists, replace the rectifier.

4.2.21 Rect Comm Fault

Possible Causes



A rectifier has been removed.



Rectifier connections are loose.



A rectifier is faulty.

Measures

1.

Check whether a rectifier has been removed. If so, reinstall it.

2.

If the rectifier is in position, remove the rectifier and reinstall it.

3.

If the alarm persists, replace the rectifier.
