Signalling concept
4.2.1
Acoustic operation signal
A periodic acoustic signal indicates that the device is functional. The acoustic
operation signal can be deactivated using the Dräger CC-Vision PC software.
4.2.2
Visual operation signal and D-Light
The visual operation signal can be extended by the D-Light feature with activated
interval check. An activated D-Light feature allows the user to also check and
indicate compliance with certain settings.
The D-Light feature can be activated using the Dräger CC-Vision PC software.
Visual operation signal with deactivated D-Light:
The green LED flashing periodically (every 5 s) indicates:
– Measurement is active
– There is no device or channel error, no gas alarm and no special state
If one of the above conditions is not met, the LED will flash according to the alarm
settings.
Visual operation signal with activated D-Light:
All the visual operation signal conditions apply. In addition, the following settings are
checked:
– 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
If one of these two conditions is not met, the green LED will flash approx. every 60 s
instead of every 5 s.
