Pressing the Function key on the DCCR program
indication window shows a broken value. What should I do for the rectifier
not in service? |
 |
First, you have to take emergency measures because the board of
DC control panel has an error. Open the air vent cover on the top
rectifier rack ; switch off the toggle switch on the HTEM-102 board;
and consult with the customer service representative. In this case, the rectifier output voltage
of rectifier is DC -52V and the load can be unbalanced. |

|
The LED does not light up on the DCCR, but
the rectifier error alarm is detected in the electric power supply room or
the switching system room. What should I do? |
|
Check the alarm system of the electric power supply room and the
switching system room. If there is no error, there may be an error
in the DCCR HTFT alarm board, so consult with the customer service representative. |
|
|
|
All the rectifier racks are normal, but
the error LED lights up in the DC control panel. What should I do? |
|
Check if a red LED lights up on each rectifier module.
Power off each rectifier module with the red LED light, and consult
with the customer service representative.

|
During a power failure, the battery supplies
the power. However, the DC output voltage goes down rapidly. What should I do? |
|
DongAh Elecomm rectifiers are connected in parallel with
the battery. The voltage drop can occur due to a battery error. Consult
with the battery provider. |
