RESERVE AC FAIL – reserve AC magnitude is out of range.
RESERVE FREQ FAIL – reserve frequency is out of range.
BATTERY LOW – DC bus (or battery) is lower than 320VDC, low battery
shutdown is approaching.
BATTERY LOW SHUTDOWN – inverter shutdown due to DC bus (or
battery) is lower than 295VDC (lower than the acceptable DC voltage of
the inverter.
RECT AC FAIL – rectifier AC magnitude is out of range.
ROTATION ERROR – rectifier AC phase rotation is incorrect.
RECTIFIER SHUTDOWN – rectifier shutdown due to DC bus too high
(over 445VDC), will automatically restart 30 seconds after abnormal
situation has been cleared.
HIGH DC – DC voltage over 430VDC and the bus voltage will be limited at
this voltage.
BOOST CHARGE – the battery is being boost charged by the rectifier.
BATTERY TEST – battery is being tested.
EMERGENT STOP – inverter shutdown due to emergent stop switch is
pushed.
DATA LINE – blinks when data is transmitted to or received from the
communication port.
C: Warning LEDs: When abnormal condition happens, these LEDs will lit to warn
the user according to the cause of the faulty condition. Therefore all these LEDs
should be extinguished under normal condition. These LEDs are as below:
RECT AC FAIL – rectifier AC input is abnormal either due to AC magnitude
out of the range or phase rotation error, rectifier shutdown.
RESERVE FAIL – reserve AC input is abnormal either due to AC magnitude
out of range or frequency out of range.
FUSE/TEMP – either inverter fuse is blown or over temperature.
OVERLOAD – output is overloaded by over 110%, 125% or 150%.
HIGH DC – the LED will lit as long as the DC voltage is over 430VDC.
