Function of AL 300

Version 3-1 05. Dezember 2019
Danger of failure of alarm messaging! Successful transmission of alarms from E*LDS components
cannot be assured in systems where CAN bus communication is severely disturbed (frequent messages
of CAN faults or actual CAN failure).
In order to ensure the correct functioning of individual alarm paths (e.g. via modem and relay contacts),
they
must be checked by triggering test alarms on a cyclical basis, see the chapter Operation.
As a rule, it must be ensured that the alarms are sent via a number of independent alarm paths .
The following messages and alarms can be generated by the AL 300 Operator Terminal:
S
Alarms
- Hardware error
- CAN bus failure/fault
- AL 300 first start
- AL 300 restart
- E*LDS component failure
- External alarms
S
Messages
- Changed configuration or date/time
3.1.1 Resetting alarms
Alarms can be reset by pressing the ALARM RESET key while the alarm log (Menu 4 - Message and Alarm
Log) is displayed. Reset is effective throughout the system, meaning that all alarms that can be reset are in fact
reset in all components.
Alarms can only be reset when reported as corrected. Reset alarms are hidden in the alarm log.
For subsequent troubleshooting, all previously acknowledged and thus hidden alarms can be dis­
played on the operator terminal again by pressing and holding (approx. 3 seconds) the buttons
MODE + ALARM RESET. These alarms can afterwards be reset and hidden in the normal manner.
3.2 Digital inputs
The operator terminal has 2 digital 230 V AC inputs (AL.1: A1/A2 and AL.2: B1/B2).
These can be configured for monitoring and alarm signalling of external maintenance groups (external alarms).
Warning - hazardous electrical voltage!
Danger of electric shock! BEFORE and AFTER
connection it
must checked that the 230 V AC relay outputs are off load!
