1.2 Use in areas subject to explosion hazards
To reduce the risk of ignition of a flammable or explosive atmosphere, strictly
observe the following warnings:
Use in areas subject to explosion hazards
Devices or components for use in explosion-hazard areas which have been tested
and approved according to national, European or international explosion protection
regulations may only be used under the conditions specified in the approval and
with consideration of the relevant legal regulations. The devices or components
may not be modified in any manner. The use of faulty or incomplete parts is
forbidden. The appropriate regulations must be observed at all times when carrying
out repairs on these devices or components.
Oxygen enriched atmospheres
Explosion protection is not ensured in oxygen enriched atmospheres (>21 Vol%
O2).
► Remove the device from the explosion-hazard area.

Technical manual | X-am® 2800 5
Conventions in this document
Oxygen-deficient atmospheres
The CatEx sensor may display false readings and incorrect measured values when
used for performing measurements in an oxygen-deficient atmosphere (<12 Vol%
O2). In this case the CatEx sensor cannot provide a reliable measurement.
► The CatEx sensor is intended to measure flammable gases and vapours mixed
with air (i.e. O2 content ≈ 21 Vol%). If the O2 content falls below 12 Vol% and an
operational O2 sensor is available in the gas detector, a channel error is
triggered on the CatEx channel due to oxygen deficiency.
► A CatEx sensor should preferably be operated with an active XXS O2 sensor so
that oxygen deficiency can be evaluated by the gas detector.
► Remove the gas detector from the area or discontinue measurement.
NOTICE
Damage to the CatEx sensor!
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicon, sulphur,
heavy metal compounds or halogenated hydrocarbon) can damage the Cat Ex
sensor.
► If the CatEx sensor can no longer be calibrated to the target concentration,
replace the sensor.
WARNING
Risk of explosion!
If the CatEx sensor is exposed to hydrogen and low temperatures (< -10 °C) for a
long time (> 1 h), measured values that are too low may be displayed. This also
applies if hydrogen is being measured but the measured gas set is not hydrogen.
► The CatEx sensor should be set to the measured gas “hydrogen”for regular and
planned measurements of hydrogen. Measuring tasks which last less than
30 min. are not affected by this.

Operation
4.2 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.

Operation
4.4 Preparations for operation
WARNING
Serious damage to health
An incorrect calibration can lead to incorrect measured values, which may result in
serious damage to health.
► Before performing safety-relevant measurements, check the calibration by
means of a bump test, adjust as necessary, and check all alarm elements. If
national regulations exist, the bump test must be performed in accordance with
these regulations.
The gas detector should be worn for personal monitoring in the proximity of the
breathing zone.
Dräger recommend using the clip to attach the gas detector to clothing either on
your collar or breast pocket. If gases are expected in a closed space that are
(much) heavier than air (e.g. CO2), then the gas detector can be worn in a lower
position, e.g. on your belt or at your hip.
The gas detector has magnetic switches. Do not put any magnets in the
immediate proximity of the gas detector (e.g. name badges with magnetic holders).
This could trigger features (e.g. bump test) on the gas detector.
1. Switch on the gas detector. The current measured values are shown in the
display.
2. Observe warnings, error messages and special states.
3. Verify that the gas inlet openings and membranes are clean, freely accessible,
dry and undamaged.
4. Check that the date and time are set correctly.
4.5 Connecting a gas detector to a smartphone
The gas detector can be connected to a suitable smartphone via Bluetooth®. The
Bluetooth® feature and the GATT (Generic Attribute Profile) interface (subject to
licensing) can be activated via the CC-Vision PC software.
Data transmitted via Bluetooth® can be used for additional safety measures.
However, the data does not replace primary on-site measures by the gas detector.
The alarm on the gas detector is decisive. An important consideration is that a
mobile network and WLAN reception are not always available or can be interrupted.
For specific features, Dräger offers apps that can be installed on a suitable
smartphone or tablet. A license may be required under certain circumstances. For
detailed information on connecting via Bluetooth® also refer to the instructions for
use of the smartphone used.
Prerequisites
– Bluetooth® is activated on the gas detector and the smartphone.

12 Technical manual | X-am® 2800
Operation
WARNING
Risk of explosion
The use of an unsuitable smartphone in an explosion-hazard area may lead to the
ignition of flammable or explosive atmospheres.
► The smartphone must be suitable and approved for use in explosion-hazard
areas.
The Bluetooth® feature is not part of the technical suitability test and may only be
used in countries for which approval is available. Contact Dräger if you have any
questions about availability.
Contamination of the gas detector or shielding elements (e.g. case) can reduce
the Bluetooth® range.
Failure of the Bluetooth® communication of the gas detector is to be expected in
the vicinity of strong transmitters in the range of the 2.4 GHz band.
When connecting a new smartphone, the connection that is currently stored is
deleted during this process.
1. Switch on the gas detector.
2. Call up the Quick menu: Press 3x in measuring mode.
3. Select and confirm the Bluetooth® connection.
4. Select the gas detector on the smartphone:
a. Short name of the gas detector in the Android/iOS Bluetooth® menu.
b. Part number and serial number in optional Dräger app.
A 6-digit number is displayed on the smartphone and on the gas detector.
5. Check that the numeric code on both devices match and, if it matches, confirm it
on both devices. The devices must be coupled within 20 s otherwise the numeric
code will become invalid.
✓Coupling of the devices is complete.
Once a connection has been successfully established, it is saved and the two
devices are automatically connected in the future (adjustable via the CC-Vision
PC software).
If the connection is lost, the gas detector automatically tries to establish a new
connection.
4.6 During operation
WARNING
Danger to life and/or risk of explosion!
The following alarms indicate a danger to life and/or risk of explosion:
– A2 alarm
– STEL or TWA alarm
– Device/channel error
► Immediately leave the hazard area.

Technical manual | X-am® 2800 13
Operation
WARNING
Incorrect measured values!
Only for diffusion mode: If water seals the gas inlets on the gas detector (e.g. in
heavy rain or if the gas detector is submerged in water), incorrect measured values
may be returned.
► With the display facing downward, shake the gas detector to remove the water.
WARNING
Incorrect measured values!
A different reading may be shown if the gas detector experiences a considerable
impact or a significant vibration.
► When using a CatEx or IR sensor (depending on the gas detector type), a
calibration of zero-point and sensitivity must be carried out after an impact load
that results in a fresh air display not equal to zero.
CAUTION
The volume of the horn is reduced!
If water gets into the opening on the horn (e.g. by immersing the gas detector in
water or due to heavy rain), the volume of the horn can be significantly reduced.
► With the display facing downward, shake the gas detector to remove the water.
Only using Bluetooth® or API applications is insufficient for raising the alarm in
safety-critical applications. Raising the alarm on the gas detector is decisive.
Contact Dräger for a description of the API interface.
Dräger recommends limiting the usage time at temperatures below -20 °C, as
the rechargeable battery life and the display may be restricted.
At temperatures below -25 °C, there may be limitations to what is shown on the
display. Dräger then recommends only using the alarm elements as a display.
WARNING
High readings outside of the LEL display range or a blocking alarm may indicate an
explosive concentration.
If the concentrations of combustible gases are too high, this may be the result of a
lack of O2.
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 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.

14 Technical manual | X-am® 2800
Operation
4.6.1 Monitoring measuring mode
In normal measuring mode, the measured values are displayed for each measured
gas. The operating signal sounds at regular intervals (configurable), and the green
LED flashes (e.g. visual operating 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 necessary)
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 37
To acknowledge an alarm:
1. Select .
4.6.3 Special state
The operation signal is deactivated during a special state. Special states are
displayed by the following visual signals:
– Yellow LED flashing – ‘warm-up 1’ special state
– Yellow LED continuously illuminated – general special state
No alarms are issued during a special state.
The special state is exited by resolving the potential error, in the event of an intact
gas detector, by switching to normal measuring mode, or automatically after
approx. 1 minute.
4.6.4 Blocking 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 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.

Maintenance
For inspection and maintenance, see e.g.:
– EN/IEC 60079-29-2 – Gas detectors - Selection, installation, use and
maintenance of detectors for flammable gases and oxygen
– EN 45544-4 – Electrical apparatus used for the direct detection and direct
concentration measurement of toxic gases and vapours - Part 4: Guide for
selection, installation, use and maintenance
– National regulations
6.2 Calibration intervals
Observe the relevant specifications in the DrägerSensor® & Gas Detectors Manual
and in the instructions for use/data sheets of the Dräger sensors installed.
Recommended calibration intervals for DrägerSensors:
National regulations may stipulate shorter intervals and must be applied.
6.3 Test gases
Test gas properties (e.g. relative humidity, concentration) can be found in the
relevant sensor data sheet.
The relative humidity of the test gas is not relevant for O2 sensors.
Different test gases are used depending on the type of calibration.
6.4 Performing the bump test
The bump test can be performed as follows:
– Manual bump test
– Bump test with the bump test station
– Bump test with X-dock
The Dräger CC-Vision PC software can be used to configure whether a quick or
advanced bump test should be performed with the menu or in the bump test station.
Dräger recommends using the extended bump test for cross calibrations (see the
Dräger X-dock instructions for use).
For the CatEx sensor, we recommend methane as the test gas, including for cross
calibration, if methane is expected in the target application.
