6.2.1.1 Operational Annunciations
Operational annunciations are information items which the device produces during op-
eration. Up to 200 operational events (central unit) and up to 50 operational events
(bay units) are stored in the device in chronological order. When the maximum capac-
ity of the memory has been reached, the oldest event will be erased.
The appendix contains a tabular list with all available operational events and their ex-
planation. Only the relevant annunciation will be displayed in the concrete situation. It
is also indicated whether the annunciation is only coming (
C for events) or whether it
is coming and going ( C/G for states).
