15.3 Error Messages and Warnings
Most of the error messages and warnings are displayed as a short message for approx. 2 seconds on
the display. There is an internal display buffer for maximum 20 short messages. If one of the 4 soft
keys below the display is pressed while a short message is shown, the short message will disappear.
A permanent message is displayed until the operator acknowledges the message with the OK-key.
There is an internal display buffer for maximum 10 permanent messages.
If a permanent message is already displayed and a new short message has to be displayed, then the
short message will be displayed firstly and afterwards the permanent message will be displayed again
until it is acknowledged by the operator.
