AC IN (green) -
• On (solid) - the external AC power (Utility or generator) is
connected to the inverters input and passing through the inverter to
power the AC loads connected to the inverter’s output.
• Blinking On (once every second) - the external AC power is
detected on the inverter’s input, but not actively being used. Either 1.
The AC input is being qualified (takes approximately 15 seconds); or
2. The input AC voltage is low. Ensure the incoming AC voltage is
above 90 volts (VAC dropout setting with the MM remote connected).
• Off - No external AC po
wer is detected on the inverter’s input.
FAULT (red) - Under normal operating conditions, the FAULT
indicator will be off. If there is a fault condition, this indicator will
blink differently for each specific fault to help troubleshoot the inverter.
Monitor this indicator for at least 10 seconds and count the number of
blinks that occur every four seconds to determine the particular reason
for the shutdown. Once you have determined and cleared the fault the
inverter can be turned on. To help clear the fault condition, refer to
the Troubleshooting section.
• Blinks On 1 time every 4 seconds -
Low Battery Voltage; the battery
voltage level has dropped below 10.0 VDC (LBCO default setting**).
Your batteries need to be charged, this fault condition will
automatically clear when the battery voltage excee
ds 12.5 VD
C.
• Blinks On 2 times every 4 seconds -
High Battery Voltage; the
battery voltage is above 15.5 VDC. Reduce or turn off the external
charging source to bring the battery voltage down.
• Blinks On 3 times every 4 seconds -
Over-temperature condition;
The internal temperature of the in
verter has risen above acceptable
limits; caused by loads too great for the inverter to operate
continuously, or by lack of ventilation to the inverter. When the unit
has cooled, it will automatically reset and resume operation.
• Blinks On 4 times every 4 seconds - AC Overload; the inverter has
turned off because the connected loads are larger than inverter’s
output capacity or there is a short on the output wiring.
The inverter
can be restarted after the AC loads are reduced or the wiring short
has been removed. To restart the inverter, momentarily press the
ON/OFF button on the inverter or remote.
• Blinks On 5 times every 4 seconds - Internal Fault; the inverter has
turned off because it has detected an internal problem. To clear this
fault, the inverter will need to be reset by: 1. Press and hold the ON/
OFF switch on the inverter for 15 seconds (the status LED must begin
to rapidly flash); or 2. Disconnect all DC power to the inverter for at
least 15 seconds and then reconnect. After resetting the inverter,
momentarily press the inverters ON/OFF switch and verify the fault
has cleared. If the Internal Fault remains, the inverter requires
service at an authorized repair facility.
