6. LCD Display.
The MR-REF & MR-REF3’s interface is fundamental to the philosophy of the Vision relay family of devices. The
screen provides access to all dynamic and historical data and protection parameters.
6.1. Menu Screens.
Upon power up the MR-REF & MR-REF3 software version screen appears for a few seconds. The screen shows the
software version and the unit type, which should be noted in all correspondence regarding the relay.
After the Introduction screen disappears then the initial display scroll page appears.
The four push buttons are used to navigate to areas of the menu structure.
Using these soft-keys provides for a very easy to use environment to effectively navigate the entire menu system.
Any description in the LCD window appearing to the
LEFT in CAPITALS can be selected using the left hand
push button.
Any description in the LCD window appearing to the
RIGHT in CAPITALS can be selected using the right
hand push button.
Otherwise the bottom right hand portion of the LCD is reserved for displaying status messages; such as, ACTIVE
FLT, E/F PKUP etc.
The centre push buttons are used to scroll the LCD
window to display different menu prompts or data.
Whilst the MENU prompt remains to the bottom left portion of the LCD, the up and down push buttons can be used
to select different pages of measured or status data, this is referred to as display scroll.
Any one of those display scroll pages can be selected as the default page, meaning if the unit is left in a sub menu –
it would automatically return to the pre-selected page within the display scroll after an adjustable period of time
