Liquid Crystal Display
You can cycle the LCD panel through a menu tree of items that provide both system display
information and adjustable parameters. Some display screens allow you to set configuration
parameters. The following diagram and tables will help you get familiar with the buttons and LEDs on
the ACS Panel and their functionality.
The top level screen for the ACS panel displays battery
voltage and current flow, either from the batteries to the
inverter (a “–” in front of the current reading) or to the
batteries from the charger (a “+” in front of the current
reading). The “–” indicates that the inverter/charger is in
inverter mode while the “+” indicates charger mode. In the example shown, the battery voltage is at
12.9 volts and the battery is being charged at the rate of 0.5 amps.
Control Buttons
The ACS LCD display panel includes four menu control keys, an ESCAPE key, an Up arrow key, a
Down arrow key, and an ENTER key. The function of each key is described below.
