4.2 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!
4.2.1 PRIO1 / PRIO2 alarm relay
The CI 3000 Store Computer has a digital alarm output (floating relay contact) for each alarm priority X1 and X2,
usable for example to operate a telephone dialer (terminals PRIO1: 35, 36, 38 / PRIO2: 25, 26, 28, see chapter
6.1.3). When an alarm is generated by an LDS component, the output assigned to the respective priority X1 or
X2 is activated.
The alarm outputs are the latching type with time-delayed automatic alarming in a power failure. The
current output states are preserved if power supply to the controller is switched off briefly. If the con
troller remains off for longer than about 5 minutes, the outputs are switched to the alarm state.
If the output was already activated, it is deactivated for an interval of 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 dur
ing this interval, the last-in alarm is postponed until the interval has expired.
The alarm outputs are automatically deactivated for instance when the alarm log contains no alarm of the re
spective priority after pressing the ALARM RESET key.
4.2.2 AUX Multifunctional relay
In addition to the prioritised alarm outputs, the controller is also equipped with a change-over contact terminal
AUX (terminal 15/16/18) which can be used to connect e.g. an external acoustic alarm transmitter via terminals
15/16/18. Via menu item 6-1-4-1 the relay output can be configured with one of the following parameters for the
following functions:
Hupe: For the connection of an external acoustic alarm transmitter (factory setting)
The contact switches when the store computer's internal buzzer sounds (buzzer signals an alarm).
If the internal buzzer falls silent then the contact also switches to the idle state
(see also chapter 4.1 Alarms and messages).
Modem: Modem hardware reset see chapter 5.3.3.
Prio. X3..X9:The multifunctional relay has the same functionality as the alarm outputs in chapter 4.2.1,
with the exception that it can be assigned any alarm priority between X3, X4, … or X9.
can be allocated. If an alarm with the priority X3,X4, … or X9 is received from one of the LDS
components then the relay output AUX is only activated when the message priority
(see also chapter 4.1) corresponds with that configured here.
DDC: For automatic modem switching to the controller (DDC) for the building management system (BMS)
