1.1 Basic safety information
– Before using the product, carefully read through these
instructions for use, the instructions for use provided with
the associated products and the general instructions for
use for sensors (9023657).
– Strictly follow the instructions for use. The user must fully
understand and strictly observe the instructions. Use the
product only for the purposes specified in the Intended
use section of this document.
– Do not dispose of the instructions for use. Ensure that they
are retained and appropriately used by the product user.
– Only trained and competent users are permitted to use
this product.
– Comply with all local and national rules and regulations
associated with this product (e.g. IEC 60079-14,
EN 60079-29-2, EN 45544-4, IEC 62990-2).
– Only specialist, trained personnel are permitted to check,
repair and maintain the product as described in these
instructions for use and the technical manual. Further
maintenance work that is not detailed in these instructions
for use or in the technical manual must only be carried out
by Dräger or personnel qualified by Dräger. Dräger
recommend a Dräger service contract for all maintenance
activities.
– Only use genuine Dräger spare parts and accessories
when performing maintenance work, or the proper
functioning of the product may be impaired.
– Do not use a faulty or incomplete product. Do not modify
the product.
– Notify Dräger in the event of any component fault or
failure.
– Substitution of components may impair the intrinsic safety
of the product.
– Electrical pairing with devices which are not listed in these
instructions for use should only be done following
consultation with the respective manufacturers or an
expert.
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:
20
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% O
► Remove the device from the explosion-hazard area.
Oxygen deficient atmospheres
The CatEx sensor may display false readings and incorrect
measured values when used for measurements in an oxygen
deficient atmosphere (<12 Vol% O
sensor cannot provide a reliable measurement.
► The CatEx sensor is intended to measure flammable
gases and vapours mixed with air (i.e. O
21 Vol%). If the O content falls below 12 Vol% and an
2
operational O sensor is available in the gas detector, a
2
channel error is triggered on the CatEx channel due to
oxygen deficiency.
► A CatEx sensor should preferably be operated with an
active XXS O or O PR sensor so that oxygen deficiency
2 2
can be evaluated by the gas detector.
► Remove the gas detector from the area and discontinue
measurement.
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 be 0 to +20 % of the
actual value. The accuracy can be corrected by
calibration.
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.
