SW Series Inverter/Charger
Part No. 2031-5
Rev. B: Sept 1, 1999
CONTRAST CONTROL
The CONTRAST adjustment enables you to adjust the contrast of the LCD display screen to accommodate
changing lighting conditions. Less contrast is usually preferable in brighter lighting conditions.
RESET TO FACTORY DEFAULTS BUTTON
The RESET TO FACTORY DEFAULTS button returns all of the inverter settings (except for the TIME OF
DAY settings) to the factory default values. The default values will be re-entered only when this button is
pushed from a specific menu item in the USER MENU. You must first select the TRACE ENGINEERING
(3) menu heading and then go to the first menu item, which will display “PRESS RESET NOW FOR
DEFAULTS”. Once this reset button is pressed from this menu item, you must reprogram all settings
required by your installation into the inverter.
Removing DC power from the inverter will also return the inverter to the factory default values
(including the TIME OF DAY settings). You must then reprogram the inverter with the required settings
for proper operation of your system. Recording your settings on the USER SETTINGS WORKSHEET, in
the TECHNICAL INFORMATION section of this manual, will make the reprogramming of the inverter
much easier.
The reset button is also used to re-synchronize the remote control (SWRC) display if the characters become
jumbled. Pressing the reset button anywhere in the menu system (except the PRESS RESET NOW FOR
DEFAULTS menu item) will re-synchronize the display, but the default values will not be reset.
MENU BUTTONS
ON/OFF MENU BUTTON (Red)
Pressing the red ON/OFF MENU button at any time will take you directly to the SET INVERTER menu
item of the INVERTER MODE (1) menu heading. There are four options available from this menu item.
The first letter of the selected item will be underlined. Pressing the red ON/OFF MENU button will move
the cursor one position to the right, selecting the next item. You can also use the SET POINTS buttons to
move either right or left.
GEN MENU BUTTON (Green)
Pressing the green GEN MENU button at any time will display the SET GENERATOR menu item of the
GENERATOR MODE (2) menu heading. There are four options available from this menu. The first letter
of the selected item will be underlined. Pressing the green GEN MENU button will move the cursor one
position to the right, selecting the next item. You can also use the SET POINTS buttons to move either
right or left.
MENU ACCESS/ADJUSTMENT BUTTONS (Black)
The MENU HEADING buttons are used to move either up or down through the selection of menu
headings. Once a menu heading is selected, the MENU ITEM buttons are used to move up or down
through the list of related menu items. The SET POINTS buttons change the value of a parameter or
select a mode, for the selected menu item.
LED STATUS INDICATORS
The Control Panel features eight colored LED indicators that identify the various operating conditions of
the inverter. Unless otherwise indicated, the LED’s will be "solid" in appearance, when illuminated.
LINE TIE (Yellow)
Selecting SELL from the GRID USAGE menu item under the INVERTER SETUP (9) menu heading will
enable sell mode. This should only be done with utility connected systems and after you have received the
approval of the local utility. This mode allows excess power to be sent into the utility grid.
INVERTING (Yellow)
The inverter is operational and AC output is available. If this LED is blinking, the inverter is in the search
mode and is looking for an AC load greater than the SET SEARCH WATTS setting.
