Error Messages
ERROR_1_x, ERROR_2_x, ERROR_3_x, ERROR_4_x, ERROR_5_x,
ERROR_6_x, ERROR_7_x and ERROR_8_x.
Error messages will appear on the display when the Micro Inverter detects
an abnormality.
Error code explanations follow:
ERROR_1_1_ : System starting error
ERROR_1_6_ : Power cord is plugged into incorrect voltage and the unit
will automatically set up the voltage as current voltage and
turn off after 3 seconds.
ERROR_2_1_: IGBT over current (DC bus over current).
ERROR_2_2_: IGBT too hot.
ERROR_3_1_: AC power lost or power up after power off time is too short (If
any of these two situations occurs, namely the island effect).
ERROR_3_2_: AC power supply error.
ERROR_3_3_: AC power frequency error.
ERROR_3_4_: (reference error) AC neutral point error.
ERROR_3_5_: (ground fault) AC ground failure.
ERROR_4_2_: DC BUS voltage too high.
ERROR_4_3_: DC BUS error.
ERROR_5_1_: Force warm up.
ERROR_5_2_: (Eng Stop) Force jump.
ERROR_6_1_: Generator over current.
ERROR_6_2_: Generator voltage error.
ERROR_6_3_: Generator too hot.
Only when Error _3_1 occurs, it will be shown for 4 seconds, then return to
Banner display; other errors will force the equipment to shut down and not
operational. Turn off the power and follow the troubleshooting procedures to
repair the equipment and resume its normal operation.
ERROR_7_1_
- Indication: When the unit is activated, it detects the stride
motor is experiencing a current overload or the stride mechanism is not
calibrated properly. Under this condition, the motor will stop working, but the
other functions can be operated normally. Turn off the unit power, the
technician will need to either inspect the stride motor or drive board.
ERROR_7_L, ERROR_7_R & ERROR_7_R/L
- Indication: There is a
communication error between control board and driver. Contact a certified
SportsArt technician. The technician will need to either inspect the stride
motor or the driver.
