2.3.1 Safety Instructions
Note the following for CSA (Canadian Standards Association)
applications:
For the CSA approval only the functions of the device
component that is used to measure flammable gases are
tested. The device is not approved by CSA for use in mining.
WARNING
CSA requirement: Measured values over the full scale
value may indicate an explosive atmosphere.
Only applicable to Class II certification. CSA Std.
C22.2 No 152 does not have any requirement for
Class II hazardous locations and therefore this device
has not been performance tested by CSA for Class II.
The sensor may become clogged and not detect gas
properly or warn the user of its inability to detect gas.
WARNING
CSA requirement: The sensitivity must be tested on a
daily basis before first use with a known concentration
of the gas to be measured in accordance with 25 to 50
% of the concentration limit value. The accuracy must
be 0 to +20 % of the actual value. The accuracy can be
corrected via calibration.
NOTICE
CSA requirement: Only the combustible gas detection
portion of this instrument has been assessed for per-
formance.
The instrument has not been classified by the CSA for
use in mines.

WARNING
Before any measurements relevant to safety are
made, check the adjustment with a bump test, adjust if
necessary and check all alarm elements. If national
regulations apply, a bump test must be performed
according to the national regulations. Faulty
adjustment may result in incorrect measuring results,
with possible serious consequences.
CAUTION
The CatEx sensor is intended for measurements of
flammable gases and vapours mixed with air (i.e. O2
content ≈21 vol.%). Incorrect measured values may
be displayed in the case of oxygen deficient or oxygen
enriched environments.
NOTICE
If the gas detector is used for offshore applications, a
distance of 5 m to a compass must be complied with.
The instrument can be operated normally. If the warning
message does not disappear automatically during
operation, the instrument must be serviced after the end
of use.
The instrument is not ready to measure and requires
maintenance.
WARNING
Explosion hazard! To reduce the risk of flammable or
explosive atmospheres igniting, it is essential that the
warning notices below are observed:
Fractions of catalytic poisons in the measuring gas
(e.g. volatile silicone, sulphur, heavy metal
compounds or halogenated hydrocarbon) can
damage the CatEx sensor. If the CatEx sensor can
no longer be calibrated to the target concentration,
the sensor must be replaced.
In case of measurements in an oxygen-deficient
atmosphere (<12 Vol.-% O2) the CatEx sensor
may show incorrect displays; in this case, a reliable
measurement with a CatEx sensor is not possible.
In an oxygen enriched atmosphere (>21 vol. %
O2), the explosion protection cannot be
guaranteed; remove instrument from the Ex area.
High values outside the display area indicate an
explosive concentration where applicable.

The setting to "Quick bump test" or "Extended bump test" is
made using the PC software Dräger CC Vision.
In the "Quick bump test" a check is carried out as to whether
or not the gas concentration has exceeded alarm threshold 1
(with oxygen, the test checks that alarm threshold 1 has not
been reached).
In the case of the “Extended bump test”, a check is made as to
whether the gas concentration has reached the set bump test
concentration within a tolerance window.
Setting on delivery: Extended bump test.
1. Prepare a test gas cylinder, the volume flow must be 0.5 l/min
and the gas concentration must be higher than the alarm
threshold concentration that is to be tested.
Example test gas cylinder 68 11 130 = mixed gas with
50 ppm CO, 15 ppm H2S, 2.5 vol. % CH4, 18 vol. % O2
2. Connect the test gas cylinder
with the calibration cradle
(order no. 83 18 752)).
3. Vent the test gas into a fume
cupboard or into the open
air (with a hose connected
to the second connector of
the calibration cradle).
4. Switch on the instrument and insert it into the calibration
cradle – press downwards until it engages.

5.3 Automatic fresh air calibration of the
CatEx sensor in the charging cradle
This feature is used to perform an automatic fresh air
calibration of the CatEx sensor after placing it in the charging
cradle. The feature can be adjusted using the Dräger CC-
Vision PC software.
5.4 1-button calibration
All sensors approved by the Dräger CC-Vision PC software
take part in the 1-button adjustment.
In the case of the 1-button calibration, the sensitivity of all
sensors is set to the value of the test gas.
When using test gas cylinder 68 11 130 = mixed gas with
50 ppm CO, 15 ppm H2S, 2.5 vol. % CH4, 18 vol. % O2.
If a mixed gas with another
composition is used,
the specified concentration
values in the instrument
must be changed to the
target values of the mixed
gas used using the PC
software Dräger CC-
Vision.
1. Connect the test gas
cylinder with the calibration
cradle.
2. Vent the test gas into a fume
cupboard or into the open
air (with a hose connected
to the second connector of the calibration cradle).
3. Switch on the instrument
and insert it into the
calibration cradle until it
engages.
4. Call the calibration menu,
enter the password and se-
lect the 1-button calibration
function, page 17.
5. Press the key to start
the 1-button calibration.
6. Open the test gas cylinder
valve to let test gas flow
over the sensor.
The currently displayed
measured values start
to flash.
The flashing stops after a static measured value has
been reached.
The calibration is now carried out automatically.
The displayed measured values change to the values
according to the gas supplied.
7. The automatic stability monitoring can be overridden by
pressing the key. A calibration is carried out immediately.
If it is detected that no test gas has been supplied,
the 1-button calibration is cancelled. The channels then
display »n/a«. If only one sensor is included in the 1-button
calibration, an adjustment is carried out in any case when
the key is pressed.
When the calibration is completed and the displayed
measured values have stabilised:
The display containing the
current gas concentration
changes with the display
»OK«.
8. Press the key or wait
for 5 seconds to quit the
calibration.
The instrument changes to
the measuring mode
9. Close the test gas cylinder
valve and remove the
instrument from the
calibration cradle.
If a fault occurs during the 1-button calibration:
The fault message » «
appears and » « is
displayed for the respective
sensor instead of the
measured value.
In this case, repeat
the 1-button calibration or
carry out a single gas
calibration, see section
5.4.1 on page 20.
Replace the sensor if
necessary, page 22.
NOTICE
Automatic surrogate calibration
If the corresponding gas combination and the sensor
are approved to do so, an automatic surrogate calibra-
tion and tests can be performed using the PC software
Dräger CC-Vision1).
A gas for the bump test, for the adjustment and the
measured gas can be set in the gas change wizard in
Dräger CC-Vision.
Conversions are performed automatically and no
longer need to be made manually.
The settings are also used by the Dräger X-dock.
1) The free of charge PC software Dräger CC-Vision can be down-
loaded from the following web address:
www.draeger.com/software
NOTICE
If the automatic fresh air calibration feature of the
CatEx sensor is activated, the user must ensure that
the charging cradle remains in normal atmosphere
(21 vol.% O2) free of contaminants for the entire
duration of the process.
NOTICE
If no sensors are approved for the 1-button adjustment
via the PC software Dräger CC-Vision, the 1-button ad-
justment menu function will not be available.
