Figure 19 Event list
The central unit event list has a maximum length of 1000 records; the bay units
100. In the event of a supply failure, the events stored in the REB500 central unit
remain intact for at least 24 hours.
Classification of events
The REB500 system includes two different event lists, the "normal" and the
"extended" events. The HMI view "Event List" enables the selection of the
respective class (see Figure 19 / Selection "Event list selection")
normal:
The "normal" event list shows mainly protection and system events including
diagnosis events in case of major/minor errors which are relevant for the user. For
normal operation of a REB500 system it is recommended to use the 'normal event
list' view.
extended:
The extended event list shows further events for diagnosis and error cause analysis.
The vast majority of minor errors falls into this group. The "extended event list"
view can be helpful for error diagnosis and support activities.
mixed:
The mixed event list shows both, the entries of the "normal" and the "extended"
view.
