3.2.2 Making the pneumatic connection
All pneumatic piping connections are located at the right-hand side of the device (see
Fig. 3).
The threaded bores G 1/4 or 1/4-18 NPT, respectively, are provided. The corresponding
screwed pipe connections have to be supplied by the customer. We recommend pipes
with the dimension 6x1 mm for the pneumatic piping.
The amount of supply pressure has to be matched to the working pressure necessary
for the actuation. The values 1.4 and 6 bar are the limit values of the positioner.
The connections have to be arranged, according to their marks, in the following way:
Mark Connection piping
- Air supply, pressure 1.4...6 bar
(20...90 psi)
OUT1 Output pressure, to actuator
OUT2 Output pressure, to actuator
(for double-acting actuators)
