4.4 MAIN SCREEN
The following diagram shows the main screen. It represents the bay scheme or mimic.
When in stand-by, none of the elements in the display is selected. By pressing the keys on the left side, we can move
through the elements on which we can operate (tap-up, tap-down, stop, automatic, manual). When selected, the
element will be shadowed, and the F4 key will show which operation can be commanded.
OPERATE F4
If we press the operation key, the relay will ask for confirmation or cancellation of the operation, as follows:
CANCEL F1
CONFIRM F2
If the operation is not performed, for example, because there is a programmed block that disables it, the display will
read:
OPERATION
FAILURE
Besides, in the main screen, instead of showing “ CANCEL ”, it will show “ MENU SELEC ”, to return to the initial menu
of the operation selection.
