2. Attach the connector arm to the valve stem connector.
3. Attach the mounting bracket to the digital valve controller housing.
4. If valve travel exceeds 2 inches, a feedback arm extension is attached to the existing 2‐inch feedback arm. Remove
the existing bias spring from the 2‐inch feedback arm. Attach the feedback arm extension to the feedback arm
(key 79) as shown in figure 4.
5. Mount the remote feedback unit on the actuator as described in the mounting kit instructions.

6. Set the position of the feedback arm (key 79) on the remote feedback unit to the no air position by inserting the
alignment pin (key 46) through the hole on the feedback arm as follows:
D For air‐to‐open actuators (i.e., the actuator stem retracts into the actuator casing or cylinder as air pressure to
the casing or lower cylinder increases), insert the alignment pin into the hole marked "A". For this style actuator,
the feedback arm rotates counterclockwise, from A to B, as air pressure to the casing or lower cylinder increases.
D For air‐to‐close actuators (i.e., the actuator stem extends from the actuator casing or cylinder as air pressure to
the casing or upper cylinder increases), insert the alignment pin into the hole marked "B". For this style actuator,
the feedback arm rotates clockwise, from B to A, as air pressure to the casing or upper cylinder increases.
Note
When performing the following steps, ensure there is enough clearance between the adjustment arm and the feedback arm to
prevent interference with the bias spring.
7. Apply lubricant to the pin of the adjustment arm. As shown in figure 5, place the pin into the slot of the feedback
arm or feedback arm extension so that the bias spring loads the pin against the side of the arm with the valve travel
markings.
