Operation Hints
Measuring Function
4.1
The use of Gas Detection Systems for explosion and health protection requires spe-
cial care. Besides qualified support of ExTox and the detailed information in the
Transmitter Data Sheets ( DB) there are several guides to assist you for the safe
use and operation of Gas Detection Systems. These guides deal with the selection,
installation, initial operation and regular maintenance.
Furthermore there could be national regulations. In Germany there are for example
the guidelines of the Berufsgenossenschaften BGI 518 and BGI 836 obligatory for
certain applications.

Application in Hazardous Areas
4.2
If the transmitter is installed in hazardous areas please pay attention to the valid
regulations. Do not open the energised device and do not perform any installation
work in hazardous areas as long as it is not ensured that there are no flammable
gases or vapours in the air. Apply for the corresponding authorisation to perform
the works first. If necessary please call in qualified staff for electrical equipment in
hazardous areas (in Germany: qualified staff according to the Betriebs-Sicherheits-
Verordnung - BetrSichV).
When closing the device please make sure that there are no cables clamped inside.
Check that all bolted connections are screwed in as far as they will go and the
measures for protection against loosening work.
You should only use transmitter cable being suitable for the use in hazardous areas,
for example as far as firing behaviour is concerned. The ExTox-Transmitter-Cable
meets these requirements.
