Safety-related information
1 Safety-related information
1.1 Information on safety notes and warnings
Safety notes and warnings warn of dangers and provide instructions for the safe
use of the product. Failure to observe these safety notes and warnings may result
in personal injury or damage to property.
1.1.1 Safety notes
This document contains sections with safety notes which warn of dangers. The type
of danger and the consequences following failure to observe the safety note are
included in every safety note.
1.1.2 Warnings
Warnings refer to steps of a task and warn of dangers which may result while the
steps are executed. Warnings appear before the steps.
1.2 Basic safety information
– Before using this product, carefully read the associated instructions for use. This
document does not replace the instructions for use.
1.3 Use in areas subject to explosion hazards
To reduce the risk of ignition of a flammable or explosive atmosphere, strictly
observe the following safety notes:
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.
X-am 8000: Increased hydrogen concentrations within the measuring range of
the DrägerSensor XXS H2HC may result in false alarms due to the additive effect
on the DrägerSensors XXS H2S and XXS CO, XXS H2S-LC and XXS CO-LC as
well as due to the negative effect on the DrägerSensor XXS O2.
Oxygen-enriched atmospheres
Explosion protection is not guaranteed in oxygen-enriched atmospheres
(>21 vol. % O2).
►Remove the device from the potentially explosive atmosphere.

Technical manual | X-am® 3500/8000 9
Safety-related information
Oxygen deficient atmospheres
Measurements in oxygen deficient atmospheres (<12 vol. % O2) may return
incorrect displays on the CatEx sensor. In this case the CatEx sensor cannot
provide a reliable measurement.
►Remove the device from the area.
The CatEx sensor in oxygen deficient or oxygen enriched environments
Incorrect measured values may be displayed in an oxygen deficient or oxygen
enriched environment.
►The CatEx sensor is intended to measure flammable gasses and vapours mixed
with air (i.e. O2content ≈21 vol. %). If the O2content falls below 12 vol. % and
am operational O2sensor is available, a channel error is triggered on the CatEx
channel due to oxygen deficiency.
Incorrect calibration
CAUTION: An incorrect calibration leads to incorrect measured values.
►CSA requirement (Canadian Standard Association): The sensitivity must be
checked daily before first using the device with a known concentration of the gas
to be measured that corresponds to 25 to 50 % of the final concentration. The
accuracy must amount to 0 to +20 % of the actual value. The accuracy can be
corrected by calibration.
RFID tag (optional)
►The RFID tag must not be read out in explosion-hazard areas.
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.
DrägerSensor CatEx 125 PR (6812950) and CatEx 125 PR Gas (6813080)
►For this gas detector, only use sensors with serial numbers > ARLB XXXX
(starting with date of manufacture in February 2018). These sensors are certified
for use in zone 0, T4.

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 33
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
