Join the pipe connections according to the designation,
observing the following points:
• All pneumatic piping connections are located on the
right-hand side of the positioner. G¼ or ¼ 18 NPT tap
holes are provided for the pneumatic connections. The
positioner is labeled according to the tap holes available.
• We recommend that you use a pipe with dimensions of
12 × 1.75 mm.
• The supply air pressure required to apply the actuating
force must be adjusted in line with the output pressure in
the actuator. The working range for the positioner is
between 1.4 and 6 bar (20 to 90 psi)**.
