9.2 7-segment display
The 7-segment display shows status and error messages.
A status message is made up of 1 to 5 digits and displayed as sequence. All messages
end with dot behind the last digit. When the first digit is 'E.', there is a permanent error.
If the cause of an error can be specified, the display indicates the actual error code fol-
lowed by a hyphen and a one-digit sub error code.
Note
Devices with older firmware do not feature the sub error code.
