3.2 Pneumatic Connections
Assuming a standard installation, with direct acting an increas-
ing signal to open the valve (rising spindle).
Before connecting any air supply make sure that the air
available is clean dry instrument air filtered to at least 25
microns.
3.2.1 Double acting
1. Connect an appropriate piece of air tubing between the port
1. on the positioner to the “A” port on the actuator. (The “A”
port is the one that, when air is applied to it, opens the
valve).
2. Connect an appropriate piece of air tubing between the port
2. on the positioner to the “B” port on the actuator. (The “B”
port is the one that when air is applied to it, closes the
valve).
3. If the positioner is required to meet enclosure rating IP54, be
sure that the sintered filter is in place at the “Exhaust” port.
4. Connect an air supply to the positioner port marked
“Supply”.
Note:
The same procedure is applicable to connect a double
acting actuator with reverse action, only select "Reverse
Action", see page 20.
For electrical installation, see page 16.
3.2.2 Single acting
1. Connect an appropriate piece of air tubing between the port
1. on the positioner to the “A” port on the actuator. (The “A”
port is the one that when air is applied to it, opens the
valve).
2. If the positioner is required to meet enclosure rating IP54, be
sure that the sintered filter is in place at the “Exhaust” port.
3. Connect an air supply to the positioner port marked
“Supply”.
Note:
The same procedure is applicable to connect a single
acting actuator with reverse action, only select "Reverse
Action", see page 22.
For electrical installation, see page 16.
