3.2.1 Alarm and signal inputs
The AL 300 Operator Terminal has two digital inputs 230 V AC for monitoring and alarming external systems/
alarms (terminals AL.1: A1/A2 / AL.2: B1/B2). The inputs are initially deactivated and must be configured prior
to use (Menu 7-5) for N.C. or N.O. operation, i.e. to signal alarm in absence or presence of signal power.
A user-definable message text of 19 characters can be assigned individually to each alarm input to be displayed
with the alarm.
Alarm is delayed for a definable time between 0 and 255 min. Each alarm input also has a definable alarm prior­
ity between 0 and 99. Alarm inputs of priority X1 and X2 generate normal alarms that are displayed in the alarm
log and transmitted via the configured alarm routes.
3.3 Relay outputs
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!
Low potential voltage and safety extra-low voltage may not be
connected toghether at the relais outputs 15/16/18, 25/26/28 and 35/36/38!
3.3.1 Alarm relays PRIO1 / PRIO2
The AL 300 Operator Terminal has a digital alarm output (floating relay contacts) for each alarm priority X1 and
X2, usable for example to operate a telephone dialer (terminals PRIO.1: 35/36/38 / PRIO.2: 25/26/28). When an
alarm is generated by an E*LDS component, the output assigned to the respective priority is activated.
If the output was already activated, it is deactivated for about 5 seconds and then reactivated (last-in alarm) if
previous activation of the output was 5 minutes or more past.
If two or more alarms are received during this interval, the last-in alarm is postponed until the interval has ex­
pired. The alarm outputs are automatically deactivated for instance when the alarm log contains no alarm of the
respective priority after pressing the ALARM RESET key.
The alarm outputs are the latching type with time-delayed automatic alarming of power failure. The current out­
put states are preserved if power supply to the controller is switched off briefly. If the controller remains off for
longer than about 5 minutes, the outputs are switched to the alarm state.
3.3.2 Horn relay 15/16/18
In addition to the prioritised alarm outputs PRIO1 / PRIO2, the controller is also equipped with a changeover
contact which can be used to connect an external audible alarm signalling unit (HORN) using the terminals
15/16/18.
