5.8 Alarms and messages
The system centre is the collection point for alarms and messages of all E*LDS components in the system. The
messages are listed in the alarm and message lists and can be called by the operator via Menu 1.
The alarm list provides a quick overview of all currently pending alarms; the message list shows the history of
the faults that have occurred and been rectified as well as all logged events. The alarm and message lists can
store 1000 entries. If the lists are full, the respective oldest entries are overwritten when new messages occur.
The messages in the list are in the order of their occurrence.
The generated messages of the E*LDS components are sent via CAN bus with one of the following priorities --,
0..99 to the system centre.
Priorities Function
--- No message is generated, no alarm is signalled
0, 10, 20,...90 Lowest priority, message entry only in the message list, no alarm is signalled
1, 11, 21,...91 High priority alarm - entry in alarm and message lists, remote alarm is signalled, local
alarm is signalled (horn),
triggering of the alarm relay PRIO1, e.g. in the event of potential stock loss
2, 12, 22,...92 High priority alarm - entry in alarm and message lists, remote alarm is signalled, local
alarm is signalled (horn),
triggering of the alarm relay PRIO2, e.g. for faults that Customer Service can rectify on
the next day
3, 13, 23,...93
4,14,34,…94
5,15,25,…95
6,16,26,…96
7,17,27,…97
8, 18, 28,...98
9, 19, 29,...99
Low priority entry in alarm and message lists, remote alarm is signalled, local alarm is
signalled (horn),
triggering of the multi-function relay AUX ONLY for one decade, e.g. X3
ATTENTION
Risk of failure of the alarm paths or alarm forwarding! In systems with highly disrupted CAN bus
communication (frequent messages of CAN faults or even CAN failures), it is not ensured that E*LDS
components can successfully forward their alarms. In order to ensure correct functioning of individual
alarm paths (e.g. via modem / relay contacts), these must be checked cyclically, for example by
triggering test alarms (Menu 4-1-7 - Other).
It must be generally ensured that alarms are signalled via multiple, independent alarm paths.
If the alarm signalling is carried out using a telephone dialling device using the provided OFF-delay
alarm contacts PRIO1/PRIO2, these must be subjected to cyclical monitoring to ensure that the
contacts also still signal in the event of power failure.
Detailed information for the alarm and message texts of the system centre is provided in
