Using the Display/Keypad
To enable a smooth and easy operation, the operator control panel has a simple layout. The LED display
is located at the top. It is used to provide information during operation / service / maintenance. It either
shows operational data, warnings or failure information in plain text combined with a time stamp and a 4
digit code which can be used in combination with the manual to show more detailed information on the
reported message.
Note!
Please refer to section
