Installation
CAUTION
Please observe the following to ensure that the
C6097 is not damaged during installation and
operation:
– Continuous operation with gases containing
more than 0.1%-by-vol. H2S or ozone con-
centrations exceeding 200µg/m

accelerate
the ageing of elastomer materials and reduce
the service life.
– Use approved sealing material only.
– Dropping the device can cause permanent dam-
age. In this event, replace the entire device and
associated modules before use.
– Check max. ambient temperature – see
page3 (Technical data).
– When using silicone tubes, only use silicone
tubes which have been sufficiently cured.
– Vapours containing silicone can adversely affect
the functioning of electrical contacts.
– Condensation or vapours containing silicone
must not be allowed to get into the housing.
At subzero temperatures, malfunctions/failures
due to icing can occur.
– When installing outdoors, place the C6097 in
a roofed area and protect from direct sunlight
(even IP65 version).
– Avoid strong impact on the unit.
– In case of highly fluctuating pressures, install a
restrictor orifice (Order No.75456321).
▷Installation position as required, preferably with
vertical diaphragm. Then the switching point pS
corresponds to the scale value SK set on the
hand wheel. In other installation positions, the
switching pointpSwill change and no longer
correspond to the scale valueSK set on the
hand wheel. Check the switching point.

For this reason, pipes carrying gas must not be
connected to port 3or 4.
▷A filter pad at port4protects the electrical con-
tacts in the C6097 from dirt particles in the sur-
rounding air or in the medium.

Wiring
CAUTION
Please observe the following to ensure that the
C6097 is not damaged during operation:
– Note the switching capacity, see page 3
(Technical data).
▷In the case of low switching capacities, such as
24V, 8mA, for example, we recommend using
an RCmodule (22Ω, 1μF) in air containing
silicone or oil.

ing pursuant to EN1854 Gas and air pressure
switches: ± 15%.
▷If the C6097 does not trip at the desired switch-
ing point, correct the adjusting range using the
hand wheel. Relieve the pressure and repeat
the process.
Tightness test
1 Shut off the downstream gas pipeline close to
the valve.
2 Open the valve and the gas supply.
▷Check all used ports for tightness.

Maintenance
In order to ensure smooth operation, check the tight-
ness and function of the C6097 every year, or every
six months if operated with biogas.
▷A function check can be carried out in case of
decreasing pressure control e.g. with the PIA.
▷ After carrying out the maintenance work, check for
tightness, see page3 (Tightness test).
