Dräger X-am 2800 Notice D'utilisation page 25

The IP degrees of protection do not extend to instances in
which the equipment detects a gas during or after its exposure
to these conditions. In the case of dust deposits and contact
with water by immersion or a jet of water, check the calibration
and functional integrity of the device.
The PEAK, STEL and TWA evaluations are interrupted if a
menu is selected.
The STEL measurement is interrupted when the pump is
connected and restarted when the pump is removed.
The TWA measurement is paused when the pump is
connected and continues when the pump is removed.
The STEL values are reset when a bump test is started,
irrespective of whether the bump test is successful or is
cancelled.
If the gas detector is used for offshore applications, it must be
kept at least 5 m away from compasses.
4.6.1 Measuring mode
In normal measuring mode, the measured values are
displayed for each measured gas. The life signal sounds at
regular intervals (configurable), and the green LED flashes
(e.g. visual life signal or D-light feature).
If a measuring range is exceeded or not reached, the
respective symbol is displayed instead of the measured value.
If, in measuring mode, an event (e.g. an alarm) occurs, the
respective symbol is displayed in the status bar (after the
event is acknowledged, if applicable) alternating with the
measured values.
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 32
To acknowledge an alarm:
1. Select .
OK
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 protection alarm protects the CatEx sensor.
Instructions for use |
X-am
® ®
2800 / X-am 5800
If the measuring range is exceeded significantly at the CatEx
channel (very high concentration of flammable substances), a
protection alarm is triggered. This CatEx protection alarm can
be acknowledged 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 the 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.
4.6.5 Panic alarm
A panic alarm can be triggered in order to request assistance
in an emergency and if there is a danger to persons or
property.
If there is an active Bluetooth connection to Dräger Gas
Detection Connect, a panic alarm can be forwarded and
assistance requested in this way.
To trigger a panic alarm:
1. Press for approx. 3 s in measuring mode.
