DC_link voltage sensor error

1.Checklist :

1) Is the input voltage of outdoor terminal block is normal?

2) Is the reactor wire connected?

3) Is the DC_link capacitor(A*V18***:CE101,CE102,CE103,A*V24***:CE001,CE002,CE003,CE004)) assembled in accordance

the specification? (Outdoor PBA)

4) Is the DC_link resistor(A*V18***:R104,R106,R107,R108,A*V24***:R004,R005,R006,R007) value is normal? (Outdoor PBA)

2. Troubleshooting procedur

Is the connected of reactor wire?

(PBA-Reactor)

Is the DC_link sensing voltage(R

104

or R004) is normal in operaƟon

mode?

Normal range (0.

Vdc~2

8Vdc)

YES

Exchange the Outdoor PBA

Is the DC_link voltage (CE101 or

CE001) is normal in operaƟon

mode?

Normal range(280Vdc~320Vdc)

Check the power input

YES

Connect the reactor wire

Restart aŌer power oī.

Start the operaƟon (cooling mode or heaƟng mode)

Exchange the Reactor

Is the reactor insulaƟon damaged?

YES

Exchange the Outdoor PBA
