7.3.8. Error List – Main display (accepting / quit error messages)
Background: If the status LED is lit or flashing in red or yellow, there are entries in the error list.
The device manages warning and alarm messages in this list and records them in the
logbook. Which messages appear, depends on the parameterization of the device. The
list can be opened by clicking on this symbol.
The error list shows all the alarms and warnings which are either currently active or have already
ended but have not yet been accepted. These alarms and warnings also affect the reaction of the
status LED. After it has been opened, the list is “frozen” to avoid having to re-sort the entries. The
list is arranged in ascending order by date and time. The last event before the display was opened is
at the top.
Time stamps (date and time of the start of the error and, if applicable, the end of the error) are shown
above each message. These time stamps for all alarms are displayed in red text and for all warnings
in yellow text.
A current error can be identified by the fact that the Ends time stamp (right) has not yet been entered
and instead empty boxes are displayed. The figure below shows an example of the error list and
explains the display in detail.
