DC voltage exceeds its limit

Check if input voltage out of limit, if not 

and the problem persists, replace driver. 

If voltage is high/Low, shut off the power 

and recommend the customer to fix the 

power supply

15

AC under voltage/AC over 

Voltage/Zero Crossing

AC input voltage is lower/

higher than limit

Check if input voltage is out of limit, if not 

and the problem persists, replace driver. 

If voltage is High/low, recommend the 

customer to fix the power supply

16

Mismatch between IDU & 

ODU models

Mismatch between IDU and 

ODU models
