If the IC701 Pin 45 (+B OVP DET) is high 2 seconds, turn AC-RELAY low (P-OFF) and make STANDBY
LED blinks three times.
If the return data Bit0 (VNG) from CXA2150Q is "1" while 2 seconds, turn AC-RELAY low (P-OFF) and
make STANDBY LED blinks four times.
If the return data Bit2 (IKREF) from CXA2150Q is "0" and there is no change for 20 seconds, make
STANDBY LED blinks five times.
At this time, AC-RELAY continues to high.
