Front Panel Display Screens and What They Mean

The front panel display shows different message screens during different modes of operation (Startup, Normal, Offline, and Fault). All single units display a basic set of message screens; multiple unit systems display additional screens in Normal Operation and Offline modes.

In addition there are Special message screens that may appear in any operational mode. All of these message screens are described in more detail in the following tables.

Startup Mode

During startup, the GT Inverter displays three message screens on its front panel LCD. These screens appear in the following order (Table 5-1).

The protection timer begins its countdown during startup and the “Reconnecting in sss seconds” screen appears until the timer countdown is complete.

Normal Operation Mode

	The LCD on the GT Inverter is refreshed every two seconds, so all readings are
	current to within two seconds. There is a default display available at all times, and
	a series of additional screens that can be displayed by tapping the Xantrex logo
	near the LCD to change the display.
Normal Operation	After the protection timer has completed its countdown and during normal
default display	operation, the GT Inverter displays the normal operation message screen shown in
	Table 5-2.
