Dräger REGARD 7000 Instructions For Use Manual page 73

– When using Dräger Pulsar / Pulsar 2 or Dräger GDxx on a REGARD-Optical-
Card, the Beam Block Open Collector output 9 on the Optical-Card must be
switched to a REGARD 7000 digital input channel with the aid of an external
relay. The digital input channel must be configured as a fault in the REGARD
7000 system.
– A REGARD 7000 relay shown in a REGARD channel cannot be acknowledged
in the REGARD after a fault on the REGARD channel. The relay must be
configured for manual acknowledgement to be able to acknowledge the
associated REGARD 7000 relay. For further information, see the following
chapter: "Parameter menu Acknowledgement mode", page 107
– In the case of a REGARD system, an over range of a REGARD channel is
displayed in the REGARD 7000 with up to 20 s delay depending on the number
of channels. The alarm triggering is not affected by this delay.
– The failure of a REGARD card generates the error message Fehler
Kommunikation in REGARD 7000. A relay configured to Comfail is not
switching.
– When integrating A3 alarms of a bridge module, ensure that the corresponding
REGARD channel can also generate an A3 alarm. This is not automatically the
case with all REGARD cards.
– The acknowledgement of a REGARD relay configured to LNAK while an alarm
condition is still present means that the acknowledgement should be performed
on the REGARD channel card once the alarm condition has been removed.
Acknowledgement via REGARD 7000 is no longer possible in this case.
WARNING
Danger of missing alarm issue or false alarms
► During the configuration of REGARD channels via the REGARD PC interface
card and the REGARD configuration software, the corresponding REGARD
7000 channels must be set to the Inhibit status.
WARNING
Danger of non-signalled special state
► During maintenance of transmitters connected to REGARD, the corresponding
REGARD 7000 channels must be set to the Inhibit status.
No alarms are issued when the Inhibit status is present.
WARNING
Danger of non-signalled special state
► Before restarting a REGARD channel card with connected transmitter to a
sensor warm-up time of more than 30 s, the corresponding REGARD 7000
channels must be set to the Inhibit status. This status is not permitted to be
removed until the warm-up process of the transmitter has been completed.
