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 specifi c 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 in the MM
Series or MM-AE Series owner's manual.
• Blinks On 1 time every 4 seconds –
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
the inverters begins charging (on models that have the internal
battery charger).
• Blinks On 2 times every 4 seconds –
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 –
the internal temperature of the
limits. This is caused by loads too great for the inverter to operate
continuously, or by a 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
• 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 fl ash) 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.
MM-RC Remote Only
The MM-RC includes three additional charging LED indicators for
information on the operation of the battery charger. Monitor the
indicators (at least 10 seconds) to determine the charger status.
