INVERTER MODE (1) MENU HEADING
Set Inverter
OFF SRCH ON CHG
Allows turning the inverter ON and OFF, enabling the SEARCH mode or selecting the charger only mode
CHG. The inverter always starts in the OFF position when powered up. Pressing the red ON/OFF MENU
button on the control panel can also access this display. Use the SET POINTS button to move the single
space cursor under the desired selection or you can continue to push the red button to move the cursor to
the right.
•
OFF - Disables the inverter. When the OFF position is selected, no power will be provided to the AC
loads even if an AC source is available. This is the default position of the inverter upon power-up.
•
SRCH - Enables the automatic load search mode control system. This system will turn on the
inverter if a large enough load is connected. If not enough AC loads are detected, the INVERTING
LED will blink slowly. The required AC load level is adjustable in the INVERTER SETUP (9) menu
heading of the SETUP MENU.
•
ON - Allows the inverter to provide AC voltage to the output and energize the AC loads either
from the battery or any “synchronized” AC source available on the input. This position must be
manually selected.
•
CHG - Allows the inverter to operate only as a battery charger. AC power will be available to the
AC loads only if an AC source is available and “synchronized”. This mode is used to prevent
discharge of the batteries by the AC loads when a utility outage occurs. This mode is only operational
on the AC1 input and when the SET GRID USAGE menu item under the INVERTER SETUP (9)
menu heading is in the FLT mode. When a different mode under the INVERTER SETUP (9) menu
heading is selected, this position will be locked out. Selecting the ‘CHG’ mode will disable the
Automatic Generator control features.
INFORMATION DISPLAY
The following information is displayed as additional Menu Items.
CHG Avail. Only in FLT mode. Press red or setpoint button to move.
Move cursor to Inverter OFF to reset Overcurrent
GENERATOR MODE (2) MENU HEADING
Set Generator
OFF AUTO ON EQ
Allows the generator to be turned ON and OFF or enables AUTO-matic and EQualization operation. This
menu display always starts in the OFF position when the inverter is powered up. Pressing the green GEN
MENU button on the control panel can access this display. Use the SET POINTS button to move the
single space cursor under the desired selection. You can also push the green button again to move the
cursor to the right.
•
OFF - Disables the ‘auto start’ system or turns off a generator that has been started by the
inverter. Also resets the automatic generator control system after an ERROR condition has occurred.
•
AUTO - Enables the automatic generator control features. When the battery voltage or load amps
reach the auto start settings for the required time period, the generator will be started unless the timer is
in the “quiet time” period. The generator will only start if the SET LOW BATTERY CUT OUT VDC setting
under the INVERTER SETUP (9) menu heading is reached for over 30 seconds continuously. If the
generator is started automatically based on battery voltage, the generator will shut off automatically once
the battery has completed the BULK and ABSORPTION stages of the battery charging process. If the
generator is started automatically based on load amps, as set in under the GEN AUTO START SETUP
(12) menu heading, the generator will turn off once the load current has decreased below the LOAD
START AMPS continuously for the LOAD STOP DELAY MIN period. The AUTO-matic generator control
operation is disabled if the ‘CHG’ mode under INVERTER MODE (1) menu heading is selected.
