In addition to the two OFF-delay alarm relays PRIO1 (1, 11, 21,...91) and PRIO2 (2, 12, 22,...92), any alarm
priority can be assigned to the multi-function relay AUX (e,g. parameter PrioX3 for 3, 13,..93 or PrioX8 for 8,
18,..98). The AUX relay is set to horn at the factory and can be configured in the Menu 4-1-7 (under "Other").
For further information about the priority concept, see chapter Priority Concept.
If the problem is rectified, the alarms in the alarm list can also be acknowledged there; for details, see chapter
Acknowledgement of alarms and messages. The acknowledgement removes the alarms from the alarm list.
The entries in the message list cannot be acknowledged or deleted. For each newly entered alarm, the audible
signalling units (internal buzzer and optional external horn at the multi-function relay AUX) are activated; see
chapter Multi-function relay AUX. The audible signalling units are switched off again by tapping the "Horn"
button in the main menu; see chapter Menu 5 - Horn.
ATTENTION
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.
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.
