Operation
4.6.2 Alarms
In the event of an alarm, corresponding displays, the visual alarm, vibration alarm
as well as the audible alarm are activated. For further information, see the following
chapter: "Alarm settings (factory setting)", page 48
To acknowledge an alarm:
1. Select .
4.6.3 Special state
If a special state is active, the life signal is deactivated. Special states are indicated
by the following visual signals:
– Flashing yellow LED – special state ‘warm-up 1’
– Continuously lit yellow LED – special state ‘general’
No alarms are issued in a special state.
If there is a potential error, the special state is ended when this is resolved. If the
gas detector is error-free, the special state is ended when it switches to normal
measuring mode. Otherwise, the special state ends independently after
approximately 1 minute.
4.6.4 Protection alarm
The blocking alarm protects the CatEx sensor.
If the measuring range is exceeded significantly at the CatEx channel (very high
concentration of flammable substances), a blocking alarm is triggered. This CatEx
blocking alarm can be acknowledge by switching the gas detector off and then on
again in fresh air.
If the gas detector cannot be switched off because the A2 alarm is active and the
switch-off mode in CC-Vision is set to “Switching off not allowed during A2”, remove
the power pack or place the gas detector in the charging cradle and allow it to
switch off automatically (only when the automatic distress signal is deactivated).
4.6.5 Automatic distress signal
When the automatic distress signal is activated, the gas detector is no longer
deactivated automatically when it is placed in the charging cradle.
The automatic distress signal can be activated via Dräger CC-Vision.
When the automatic distress signal is activated, an alarm is triggered in measuring
mode if the gas detector is not moved for an adjustable period.
Default setting: Pre-alarm: 20 s, main alarm: another 10 s
The automatic distress signal can be paused for 15 min via the Quick menu.
To confirm a pre-alarm:
1. Press any key or move the gas detector.
To confirm a main alarm:
1. Press any key.
