4.3 Signalling concept

4.3.1 Acoustic operation signal

A periodic acoustic signal indicates that the device is
functional. The acoustic operation signal can be
deactivated. For further information, see the following
chapter: "Activating silent mode", page 34

4.3.2 Visual operation signal

A periodic pulse (increasing and decreasing intensity)
of the green LED indicates:
– Monitoring, confined space entry, leak search or
benzene/pre-tube measurement application active
– There is no device or channel error, no gas alarm
and no special state
4.3.3 Visual operation signal with activated
D-Light
An activated D-Light feature allows the user to also
check and indicate compliance with certain settings:
– Evaluation of bump test intervals activated and
complied with (factory setting) or evaluation of the
calibration intervals active and complied with
– Usage interval complied with
The D-Light feature can be activated using the Dräger
CC-Vision PC software.
Signalling visually corresponds to the operating signal.
If one of the conditions listed is not fulfilled and the D-
Light is activated, the greed LED will switch on briefly at
regular intervals (short flash approx. every 60 s) instead
of pulsing periodically.
