3. Install the mounting plate (key 21) on the actuator using the four cap screws and washers (keys 23 and 24). The

transmitter and bracket can be mounted in any of four positions by using the cap screws (key 23) on the face of the

actuator hub.

4. Tighten the cap screws (key 23) slightly while aligning the potentiometer shaft on the transmitter with the coupler

plate assembly pin (key 57). When aligned, tighten the four cap screws (key 23). Maintain this alignment while

tightening the two cap screws (key 32) holding the transmitter to the mounting plate (key 21).

5. Slide the coupler (key 52) over the potentiometer shaft and into the hole in the mounting plate (key 21). Slide the

coupling (key 54) onto the plate assembly pin and attach the coupling to the plate assembly pin using the set screw.

6. Slide the coupler (key 52) into the coupling (key 54). The coupling should not be deflected in any direction when

installed. Do not tighten the coupling set screw (key 53) as it will be tightened during the potentiometer alignment

procedure.

7. Perform the electrical connections and potentiometer alignment procedures.

Long‐Stroke Sliding‐Stem Fisher 585C and 470‐16 Actuator Mounting; 4220, 4221, and 4222

Transmitters

Use the following general procedures and figure 22 to mount the transmitter on long‐stroke sliding‐stem 585C and

470‐16 actuators with 105 to 206 mm (4.125 to 8.125 inches) travel.

CAUTION

To avoid damaging the potentiometer after the transmitter is mounted, do not stroke the actuator without first loosening

the socket screw set (key 100F) that fastens the coupling (key 100E) to the potentiometer shaft (key 5).

1. Stroke the actuator to mid‐stroke.

2. Bolt the cable bracket (key 60) to the stem connector on the actuator stem. To do this, first replace the existing

stem connector cap screws with studs (key 78). Slide the cable bracket (key 60) over the studs (key 78) before

installing the nuts (key 71). Tighten the nuts (key 71).

3. If necessary, refer to the appropriate actuator instruction manual for the procedure to reconnect the actuator stem

to the valve stem.

4. Attach the cable transducer housing (key 100A) to the mounting plate (key 63) using cap screws (key 103) and hex

nuts (key 104).

5. Attach the mounting plate (key 63) to the actuator using hex head cap screws (key 32). Note: Some actuators may

require spacers (key 101) between the mounting plate (key 63) and the actuator.

CAUTION

Free release of the cable (key 100B) will damage the transducer. Whenever the cable (key 100B) is extended, take steps to

ensure that free release does not happen.

6. Carefully pull the cable (key 100B) down to the cable bracket (key 60) and attach it with the socket head cap screw

(key 102), the lock washer (key 83) and the nut (key 72).

7. Remove the four cap screws (key 100D) and the mounting plate (key 100C) from the cable transducer.

8. Mount the mounting plate (key 100C) to the transmitter using cap screws (key 105).

9. Verify that the actuator is still in the mid‐stroke position. Loosen the socket cap screws (key 100F) and rotate the

coupling until the socket cap screws (key 100F) can be accessed with a hex wrench through one of the openings in
