Safety Instructions Part A
The device is only designed for situations of intended use. A non-intended use can lead to personal
injury and property damage. Only use the device as intended.
The device measures combustible or explosive gases and is installed in their environment. There is
a potential risk of spread or ignition of a hazardous atmosphere. Make sure to observe the rules
regarding explosion protection.
Biogas contributes to the greenhouse effect and thus to climate change. If possible, do not
discharge gas into the atmosphere.
The rated overpressure is 100 mbar. In case a precision pressure regulator is installed, this may
fail (snagged membrane). A higher pressure may cause damage and leaks, whereby an explosive
atmosphere could arise. Ensure that no more than 100 mbar pressure is reached. Set a pressure
regulator before the precision pressure regulator to max. 100 mbar . The risk for pressure control
systems for process gas with an input pressure above 100 mbar is to be considered separately,
because in case of failure, large amounts of gas could leak out.
Parts inside the device are under electrical voltage. Danger to life by electric shock! ALL installation/
repair/maintenance operations on the gas analysis system or on the whole plant must only be carried
out in a de-energized state and when the system is completely turned off. Observe electrical safety
regulations.
Biogas contains hydrogen sulphide. Gas leakage can lead to acute inhalation toxicity. At a
concentration of hydrogen sulphide of more than 22,000 ppm or room volumes that are less than
the standard container size (32 m³) or air exchange rates of less than once per hour, the risk of a
possibly even deadly poisoning caused by hydrogen sulphide needs to be assessed individually and
appropriate measures have to be taken. Avoid small room volumes and low air exchange rates.
An improperly performed installation, electric installation, initial operation, or maintenance of the
gas analysis system may cause hazards, especially due to gas and electrical current. These activities
must therefore only be performed by trained personnel. The specialist personnel must have read
and understood the Instruction Manual and follow its instructions.
„Hydrogen sulphide is toxic. Watch out for smell of rotten eggs. Ventilate the room and do not
enter."
„Carbon monoxide is toxic. A suitable gas warning sensor must be used, unless the ventilation is
sufficient."
