7.1 Troubleshooting Rectifier

1. Troubleshoot Rectifier according to LED Indication

The usual fault symptoms of the rectifier include: power indicator (green) off, protection indicator (yellow) on, protection indicator (yellow) blinking, alarm indicator (red) on, and alarm indicator (red) blinking.

Symptom

 

Cause

 

Suggestion

 

 

 

No input voltage

 

Make sure there is input voltage

 

 

 

 

 

 

 

Power indicator (green) off

 

Input polarity reversed or input fuse

 

Replace the fuse with a new one of the same

 

 

 

model or reconnect the input power with

 

 

 

blown

 

 

 

 

 

correct polarity.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

AC input voltage outside the normal

 

Ensure the AC input voltage remain within

 

 

 

range

 

normal range

 

 

 

 

 

 

 

 

 

PFC over-voltage

 

Replace the rectifier

 

 

 

 

 

 

 

 

 

Current sharing function is disabled

 

Replace the rectifier

 

 

 

 

 

 

Protection indicator (yellow)

 

Rectifier over-temperature protection, which is caused by:

 

 

 

 

 

 

 

1. Fan blocked

1. Remove the obstacle that blocks the fan

 

on

 

 

 

 

 

 

 

 

 

2. Ventilation blocked: the inlet or

 

2. Remove the objects that blocks the inlet or

 

 

 

outlet blocked

 

outlet

 

 

 

 

 

 

 

 

 

3. Ambient temperature too high or

 

3. Remove the heater, lower the ambient

 

 

 

rectifier inlet too close to an heater

 

temperature

 

 

 

 

 

 

 

 

 

Rectifier not inserted into the slot

 

Insert the rectifier again properly

 

 

 

completely

 

 

 

 

 

 

 

 

 

 

 

 

 

Protection indicator (yellow)

 

Rectifier communication failure

Check the communication cables

 

blinking

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Remove the rectifier from the DC power

 

Alarm indicator (red) on

 

Rectifier over-voltage

 

system, restart the rectifier, and replace the

 

 

 

 

 

rectifier if over-voltage still occurs.

 

 

 

 

 

Alarm indicator (red) blinking

Fan not running

Replace the fan

 

 

 

 

 

 

2. Rectifier Current Sharing Unbalanced

When multiple rectifiers are in parallel connection and the unbalance of current sharing among them is bigger than 3%, check if the communication cables are correctly connected.
