Air supply requirements
Max. air supply pressure, see the section
Technical Data on page 20.
The supply air must be free from
moisture, water, oil, and particles.
The supply air must be dried or be treated
in such a way that its dew point is at least
10
°C (18°F) below the lowest expected
ambient temperature.
Before the air supply is connected to the
positioner, we recommend the hose is opened
freely for 2 to 3 minutes to allow any con-
tamination to be blown out. Direct the air jet
into a large paper bag to trap any water, oil,
or other foreign materials. If this indicates
that the air system is contaminated, it should
be properly cleaned.
To ensure a stable and problem-free ope-
ration, we recommend the installation of a
filter/pressure regulator <40
µ as close to the
positioner as possible.
WARNING. Do not direct the
open air jet towards people or
objects because it may cause
personal injury or damage.
Poor air quality is the main source of
problems in pneumatic systems.
