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. G1/4 or 1/4 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 line with dimensions of 12
x 1.75 mm. The level of 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 ... 10 bar (20 ... 145 psi).
