Fault LED Indicator
– Under normal operating conditions, the
FAULT LED (red) indicator will be off. If there is a fault condition, this
indicator illuminates to indicate that a fault condition has shut down
the inverter. When the FAULT LED comes on, count the number of
times it blinks (before turning off for two seconds) to determine the
particular reason for the shutdown. Once you have identi
fi
ed and
cleared the fault, the inverter can be turned on. To help clear the
fault condition, refer to the Troubleshooting section.
• Blinks x1,
then off for 2 secs
–
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
automatically clears when the battery voltage excee
ds 12.5 VD
C.
• Blinks x2,
then off for 2 secs
–
High Battery Voltage
; the
battery voltage is above 16.9 VDC. Reduce or turn off the external
charging source to bring the battery voltage down.
• Blinks x3,
then off for 2 secs
–
Over-temperature Condition
;
the internal inverter temperature
is above acceptable limits. This
may be 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 automatically resets and resumes operation.
• Blinks x4, then off for 2 secs
–
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.
Restart the inverter once 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 x5, then off for 2 secs
–
Internal Fault
; the inverter
has turned off because it has detected an internal problem. To
clear this fault, the inverter needs to be reset: 1) Press and hold
the inverter’s ON/OFF switch for 10 seconds (inverter goes thru
power-up test – see Section 4.1.1); 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 cleared. If the internal fault remains,
the inverter requires service at an authorized repair facility.
• Blinks x6, then off for 2 secs
–
High AC Volts
; this fault causes
the AC input to be disabled because a very high AC voltage
(>145 VAC) has been detected on the AC input. To clear this
fault, remove all AC power from the inverter’s AC input for at
least 15 minutes. Ensure only 120 VAC power is connected to the
inverter’s AC input.
4.1.1 Power-up LED Test
When the inverter is
fi
rst connected to the batteries, the inverter
and remote go through a power-up LED test. This test veri
fi
es the
inverter’s LEDs by requiring all LEDs to come on in sequence from
the
fi
rst (INV) to the last (FAULT), and after all LEDs are on for 2
seconds they all turn off.
