Replacing PCB board 

 

Note 

Care should be taken when replacing components of the controller. Unplugging terminals optionally may result in system shut 
down. Carry out the replacement sequentially according to the following procedures.   

 

1. Unplug J426, J427 and J421 terminals to prevent shutting down of the power supply system. 

2. Unplug the J421 power supply terminal to power off the PCB board. 

3. Unplug other terminals and DI/DO cables. 

4. Wrap the DI/DO cable terminals with insulating tape. Keep the unconnected terminals and cables insulate from 

components of the power supply system and the PCB board to prevent short circuit. 

5. Remove the fixing screws of the PCB board and replace the PCB board. Note that the screwdriver should be 

prevented from touching the bare parts of the signal cables to prevent short circuit. 

6 Connect the signal cables in reverse sequence, that is, reconnect signal cables other than J421, J426, J427 

terminal cables and DI/DO cables. 

7. Check the cable connections. If the connections are correct, reconnect J421 terminal. If the watchdog indicator 

blinks and the power indicator is on, the PCB board works normally. 

8. Check the voltages of J426 and J427 terminals with a multimeter. Make sure that they output low voltage. Connect 

J426 and J427 terminals. 

9. Set the parameters of the controller according to 

4.7    Setting

. 

Replacing LCD 

The procedures of replacing LCD are described as follows: 

1. Unplug J426, J427 and J421 terminals of the PCB board. 

2. Unplug the J3 terminal tape cable connected to the LCD. 

3. Replace the LCD. Restore the J3 terminal tape cable. Pay attention not to short the LCD with the power supply 

system or the LCD with the PCB board. 

4. Connect J421 terminal. 

5. Check the voltages of J426 and J427 terminals with a multimeter. Make sure that they output low voltage.   

6. Connect J426 and J427 terminals. The replacement is complete.
