Operational Hints
According to the relevant national regulations, gas warning instruments have to pass a function test,
done by a specialist, after having been installed but before put in operation. For Germany,
§ 56(2) "UVV Gase" (BGV B6 - formerly VBG 61) is applicable.
Before shipment, the transmitter has passed a function and display test, being calibrated with suitable
test gases. This does not, however, overrule the obligation of putting in operation with test gas
after the installation.
The transmitter CC28 (including CC28 D and CC28 DA) is approved for the use in explosion
endangered areas and is subject to an EC-Type Examination Certificate issued by EXAM BBG Prüf-
und Zertifizier GmbH, according to directive 94/9/EG (ATEX100a) with the following
Certificate: BVS 04 ATEX E 132 X
Labelling: ¯ II 2G EEx dem [ib] IIC T4 -20°C≤Ta≤+50°C
For the use in explosion endangered areas, with a measuring function for explosion protection, the
EXAM BBG Prüf- und Zertifizier GmbH issued an EC-type examination certificate for the transmitter
as per directive 94/9/EG.
Certificate: BVS 05 ATEX G 001 X
The test was based on the standards DIN EN 61779-1 "Electrical apparatus for detection and
measurement of combustible gases – General requirements and test methods" and DIN EN 61779-4
"Electrical apparatus for detection and mesurement of combustible gases – Requirements for the
operational behaviour of apparatus of group II with a detection range up to 100 % of the Lower
Explosion Limit" and the DIN EN 50271 „Electrical devices for the detection and measurement of
combustible gases, toxic gases or oxygen – Requirements and testing for warning devices using
software and/or digital technology“.
