(7) Inverter checker for diagnosis of inverter output
㵘䃂
Checking method
(a) Model: SRC40-60
1) Setup procedure of checker.
a) Power OFF (Turn off the breaker).
b) Remove the terminal cover of compressor and disconnect the wires (U, V, W) from compressor.
c) 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.
2) Operation for judgment.
a) Power ON and start check operation on cooling or heating mode.
b) Check ON/OFF status of 6 LED's on the checker.
c) Judge the PCB by ON/OFF status of 6 LED's on the checker.
d) Stop check operation within about 2minutes after starting check operation.

(b) Model: FDC71-140
1) Setup procedure of checker.
a) Power OFF (Turn off the breaker).
b) Remove the terminal cover of compressor and disconnect the wires (U, V, W) from compressor.
c) Connect the wires U (Red) , V (White) and W (Black) of checker to the terminal of disconnected wires (U, V, W)
from compressor respectively.
2) Operation for judgment.
a) Power ON after JSW10-4 on outdoor inverter PCB was turned ON.
b) After 15 seconds since power has turned ON, LED start ON/OFF for 5 seconds cyclically and it repeats 10 times.
c) Check ON/OFF status of 6 LED's on the checker.
d) Judge the PCB by ON/OFF status of 6 LED's on the checker.
e) Be sure to turn off JSW10-4 on outdoor inverter PCB, after finishing the check operation.
