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.
