SCREEN
DSP and MCU communication Failure. When the communication between the INV control board
and the COMM board is interrupted, the fault signal will be displayed.
Input and output phase sequence is not compatible. Input and output phase sequence different.
Bypass SCR short. There isn't signal drive the bypass SCR close, but bypass output voltage higher.
Bypass SCR open. There is signal drive the bypass SCR close, but bypass output voltage is lower
than normal.
Inverter R waveform abnormal. The voltage difference between the inverter reference and in-
verter sample is greater than normal.
Inverter S waveform abnormal. The voltage difference between the inverter reference and in-
verter sample is greater than normal.
Inverter T waveform abnormal. The voltage difference between the inverter reference and inver-
ter sample is greater than normal.
Bypass output short (L-N). Bypass O/P voltage drop too fast and O/P current more than normal.
Bypass output line short (L-L). Each of line current more than normal, but line plus line current
lower than normal.
Inverter Relay short circuited. There isn't signal drive the Inverter Relay close, but inverter out-
put voltage over normal.
BUS voltage vary fast. BUS voltage drop too fast in Inverter mode.
Current detect error. Inverter current and share current and output current sample deviation
more than normal.
SPS Power fault. SPS 12V power lower than normal.
Battery polarity reverse.
R PFC IGBT over current fault . The unit have detected IGBT fault signal from the drive board.
S PFC IGBT over current fault. The unit has detected an IGBT fault signal from the drive board.
T PFC IGBT over current fault. The unit has detected an IGBT fault signal from the drive board.
R INV IGBT over current fault . The unit have detected IGBT fault signal from the drive board.
S INV IGBT over current fault. The unit has detected an IGBT fault signal from the drive board.
T INV IGBT over current fault. The unit has detected an IGBT fault signal from the drive board.
ISO transformer over temperature. Output ISO transformer or Auto transformer over temperature.
LCD and MCU communication failure. Touch panel and MCU communication failure.
