Failure Modes - Double acting

The standard setup for double acting actuators is so that an
increasing input signal opens the valve. Signal failure, then,
moves the valve to the closed position . This may be changed
to “Open on signal failure” by changing the setup to REVERSE
ACTING.

The effect of signal and air failure depends on the way the air
connections and the potentiometer connections are made:

5.1.1 Changes for Reverse Acting

To change from the standard setup to reverse acting:

1. Change the tubing (see fig. 5.1).
2. Remove the cover.
3. Change the action jumper setting by setting both jumpers to

the right side (see fig. 5.2).

4. Replace the cover taking care that the “O” ring seal is in

place and the fixing screws are tightened correctly.
