Appendix A - Remote Control and Monitoring
31
• Off - The inverter
is disabled. The inverter is not on or will not come on if
AC power is lost or disconnected.
AC IN
(green)
-
• On (solid) - the external AC power (utility/shore power or generator)
is connected to the inverter’s 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 quali
fi
ed (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 speci
fi
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.
• 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 the 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
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 inverter’s ON/OFF switch and verify the fault has
cleared. If the internal fault remains, the inverter requires service at an
authorized repair facility.
