The Man-Machine Interface (MMI) consists of a liquid crystal display, control keys and LEDs
that allow full use of the Converter’s features. The Liquid crystal display can be seen through
the hinged cover that protects the MMI. Lower the protective cover to see the control keys.
The MMI provides for application programming and monitoring of the Converter for remote
control.
Welcome Screen
On power-up, a self-test is displayed. This is quickly replaced by a default Welcome screen
showing the product description and software version of the Converter. The display then
changes to MENU LEVEL after a further 15 seconds (you can press the M key to display this
screen immediately). This screen is at the top of the MMI’s menu system.
