CAUTION – Overpressure!
The operating pressure of the gas applied to
the device must not exceed 1 bar. If the gas is
supplied at a higher pressure, the valves inte-
gral to the device may not close correctly and
the gas supply control may be impaired.
Set the gas supply to a range between 0.8 bar
min. and 1.0 bar max. and make sure that this
pressure setting cannot be changed!
NOTE – Pressure compensation opening
To ensure permanent pressure compensation,
the pressure compensation opening must not
be connected to an exhaust air system. The
pipe of the pressure compensation opening
must not be extended or redirected.
NOTE – Access port
If the access port is not used, it must be cap-
ped during operation.
