STATUS LEDs
Each Status LED performs two functions,
providing battery type selection and operation
status.
OPERATION
Operation Status
INVERT - Green LED
• When the LED is solid green, the unit is
in invert mode. This occurs by pressing the
INVERT switch.
• When the LED is blinking slowly (1 time
per second), the inverter is in standby with AC
power applied and the transfer switch engaged
• When the LED is OFF, the inverter is
OFF.
CHARGE - Green LED
• When the LED is solid green, the unit is
in the charge mode and external AC power is
being supplied.
• When the LED is blinking slowly, (1 time
per second) the charger is ready, but external
AC power is not available.
• When the LED is OFF, the charger has
been manually turned OFF. This can only be
accomplished while AC power is being
supplied.
NOTE: When AC power is available, the
default setting for the charger is ON. If the unit
was manually turned OFF and AC power is in-
terrupted and becomes available again, the
charger will return to ON.
LOW BATTERY - Red LED
When the LED is OFF the battery
voltage is normal, between 10.5 and 15.0
volts DC.
• When the LED is solid red, it indicates a
battery warning condition, the battery voltage is
below 10.5 volts DC or above 15.0 volts DC.
• When the LED is blinking slowly, (1 time
per second), a battery shutdown has occurred.
The voltage is either below 10.0 volts DC or
above 15.5 volts DC.
• When the LED is blinking rapidly (5
times per second), a potential problem in the
DC system has been detected. Check your
batteries, battery cables and DC loads.
OVERTEMP/OVERLOAD - Red LED
When the LED is Off operation is
normal.
• When the LED is red, there is an over
temp or overload condition. Check for
excessive loads or short circuit on the output
of the inverter. Correct the condition and restart
by pushing the INVERT switch.
• When the LED is blinking slowly (1 time
per second), an over current condition or a
short circuit has occured. The system has
shut OFF and will not automatically restart.
Correct the fault condition and manually restart
the system.
