5.11 Power failure during grinding
If the power fails during grinding, grinding will be interrupted. All parameters are
retained, and the remaining grinding time is saved. When the device is switched
on again, a corresponding message appears in the display.
You can continue the process by pressing the START button. The automatic
saving of the remaining grinding time means the grinding then continues until the
end of the originally set grinding time.
For safety reasons the device must be opened and the grinding chamber
inspected. Grinding then continues automatically when the lid is closed.
The process is aborted by pressing the STOP button.
