level M3: Tests on coffee grinder
This level allows the service engineer to check
operation of the coffee grinder.
The first line shows a description of the level and
a space for analog information, if present (red
circle).
The second line shows whether or not the load is
active (blue circle). Additional information is shown
in the red circle and the flashing “X” (green circle).
When the coffee grinder is operating (up button) the
speed is shown in rpm (red circle ) and the “X” flashes
(green circle).
“v” can show one of the Aroma levels: 0 - 1 - 2 (see
heading 2.3.2). The value can be edited with the
doWn button and saved by pressing ok.
If the value has been edited but not saved the
“*” symbol will be displayed at the end of the second
line. When the value is saved, the “*” symbol
disappears.
