Chapter 7 Troubleshooting

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.

Table 7-1 Troubleshooting

Symptom Cause Suggestion

No input voltage Make sure there is input voltage

Power indicator (green) off Input polarity reversed or input fuse

blown

Replace the fuse with a new one of the same

model or reconnect the input power with

correct polarity.

AC input voltage outside the normal

range

Ensure the AC input voltage remain within

normal range

PFC over-voltage Replace the rectifier

Current sharing function is disabled Replace the rectifier

Rectifier over-temperature protection, which is caused by:

1. Fan blocked 1. Remove the obstacle that blocks the fan

2. Ventilation blocked: the inlet or

outlet blocked

2. Remove the objects that blocks the inlet or

outlet

3. Ambient temperature too high or

rectifier inlet too close to an heater

3. Remove the heater, lower the ambient

temperature

Protection indicator (yellow)

on

Rectifier not inserted into the slot

completely Insert the rectifier again properly

Protection indicator (yellow)

blinking Rectifier communication failure Check the communication cab les

Alarm indicator (red) on Rectifier over-voltage

Remove the rectifier from the DC power

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.
