Description
Normal
Power circuit board
Overvoltage error
Controller circuit board
Undervoltage error
Input current sensor error
Controller circuit board
L1 or L2-phase open error
Abnormal power
Power circuit board
synchronous signal
Check CNAF wiring.
ACTM error
Defective ACTM/ P.B
Undervoltage
Display examples for multiple errors:
Overvoltage (01) + Undervoltage (02) = 03
Undervoltage (02) + Power-sync signal error (08) = 0A
L1 phase open error (04) + ACTM error (20) = 24
