PS Series Inverter/Charger
Part No. 3597
Rev. D: November 23, 1999
MENU HEADING - INVERTER MODE (1)
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 SWRC can also access this display. Use the SET POINTS button to move the single space
cursor under the desired selection.
• 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 with the SEARCH WATTS setting in
the INVERTER SETUP (9) menu.
• ON - Allows the inverter to provide AC voltage to the output and energize the AC loads either
from the battery or from 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
with the MAXIMUM AC AMPS IN switch is in the AC1 position 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 Start features.
INFORMATION DISPLAY
The following information is displayed as additional Menu Items.
CHG avail. Only in FLT mode. Press setpoint button to move cursor.
Move cursor to Inverter OFF to Reset Over Current.
MENU HEADING - GENERATOR MODE (2)
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 SWRC can access this display. Use the SET POINTS button to move the single space
cursor under the desired selection.
• OFF - Disables the ‘auto start’ system or turns off a generator that has been started by the
inverter. Also resets the automatic generator start system after an ERROR condition has occurred.
• AUTO - Enables the automatic generator start features. Allows the generator to be started
automatically based on battery voltage, load amps or exercise time. 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 battery charging stages. 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. If the generator is started automatically
based on exercise time, the generator will turn off after running for 15 minutes continuously.
• ON - Starts the generator that is controlled by the inverter. If this position is selected, it will
manually turn on the generator that is connected to the GEN CONTROL relays. The OFF position
must be selected to manually turn the generator off.
