(c) Inverter checker for diagnosis of inverter output
䖃Checking method
(i)
1) Power OFF (Turn off the breaker).
2) Remove the terminal cover of compressor and disconnect the wires (U, V, W) from compressor.
3) Connect the wires U (Red) , V (White) and W (Black) of the checker to the terminal of disconnected wires (U, V, W)
from compressor respectively.
(ii)
1) Power ON after JSW10-4 on outdoor inverter PCB was turned ON.

5sec.
During this period, ON/OFF status of LED is
repeated cyclically according to following pattern.
2) After 15 seconds since power has turned ON, LED start ON/OFF for 5 seconds cyclically and it repeats 10 times.
3) Check ON/OFF status of 6 LED's on the checker.
4) Judge the PCB by ON/OFF status of 6 LED's on the checker.
