CAUTION
To ensure that the C6097 is not damaged dur-
ing operation, note the switching capacity, see
page5 (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.

▷ C6097A: the NO-to-COM connection is inter-
rupted if the pressure drops (contacts 3 and
2 open).
C6097B: the NC-to-COM connection is inter-
rupted if the pressure rises (contacts 3 and 1
open).
Adjustment
▷ The switching point is adjustable via hand wheel.
1 Disconnect the system from the electrical power
supply.
2 Detach the housing cover.
▷ Tightening torques, see Technical Information
bulletin C6097 at www.docuthek.com.

6 Apply pressure. In doing so, monitor the ohm-
meter and the pressure gauge.
▷ Adjusting range, switching differential and max.
inlet pressure, see page6 (Type table).
▷ 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.
Pressure switches with manual
reset
▷ C6097A3012, C6097A3038, C6097A3095,
C6097A3111 lock off if the pressure drops to
the set value.
▷ C6097B3002, C6097B3028, C6097B3051 lock
off if the pressure rises to the set value.
1 Reset the pressure switch using the manual reset.
▷ Requirement for reset:
C6097A: the pressure must have risen at least
to the set switching point plus the pressure dif-
ferential between the switching pressure and
possible lock-off.
C6097B: the pressure must have dropped at
least to the set switching point minus the pres-
sure differential between the switching pressure
and possible lock-off.
▷ For details of the pressure differential between
the switching pressure and possible lock-off, see
page6 (Type table).
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 .
