6. Operation
On/Off/Charger Only Switch
The switch is located on the underside to the bottom right of the product.
The switch has three positions. The centre position 0 is Off. The I position is On, and the II position is Charger Only.
When switched to 'I / On' (rocked towards the front of the unit), the product will come into operation and the inverter is
fully functional.
If an AC voltage is connected to the 'AC in' terminal, it will be switched through to the 'AC out' terminal, if within
specifications. The inverter will switch off, and the charger commences charging. 'Bulk', 'Absorption' or 'Float' will display,
depending on the charger mode.
If the voltage at the 'AC-in' terminal is rejected, the inverter will switch on.
When the switch is switched to 'II / Charger Only', only the battery charger of the Multi will operate (if mains voltage is
present). In this mode input voltage also is switched through to the 'AC out' terminal.
NOTE: When only the charger function is required, ensure that the switch is switched to 'II / Charger Only'. This prevents
the inverter from being switched on if the mains voltage is lost, thus preventing your batteries from running flat.
7. GX LCD Interface
The display screen will present useful information about your system.
7.1 On/off behaviour
When the product is switched off with the physical switch on the device or with the Remote On/Off terminals, then the GX
card is off as well. If you switch the product remotely, using a Digital Multi Control, then the GX card will remain powered.
Also when switching the inverter/charger off from within the GX menus, the GX card will remain powered.
Lastly, when the inverter/charger switches itself off due to an alarm, such as low battery or overtemperature, then the GX
card will remain powered and functional as well.
7.2 Push button behaviour
When the GX Card is on, pushing the button beside the screen will activate the backlight. The backlight will turn itself off
after 5 minutes.
Once the backlight has been activated, pushing the button again will cycle through the available display options. Some
options will be displayed automatically, and others require a button push to display.

7.4 Error Code Display
If there is an error with the system, the error code will be displayed on the screen. The screen will display VE.Bus error
code numbers, and MPPT error codes (if connected).
Basic information about the VE.Bus Error codes are in the Error Indications section.
For further details about the error codes please see:
