Sliding‐Stem Actuator Mounting; 4210, 4211, 4212, and 4215 Transmitters
Use the following general procedures and figures 15, 16, 17, and 18 to mount the transmitter on sliding‐stem
actuators, standard stroke up to 105 mm (4.125 inches) travel.
Refer to figure 15 for key number locations for this example.
1. Install the transmitter on the mounting plate (key 21) with two cap screws (key 32).
2. Bolt the stem mounting bracket and spacer (keys 34 and 39) to the stem connector on the actuator stem. Replace
the stem connector cap screws with the two cap screws (key 35) furnished with the stem mounting bracket.
3. If necessary, refer to the appropriate procedures in the actuator instruction manual to reconnect the actuator stem
to the valve stem.
4. Fasten the stem bracket (key 33) to the stem mounting bracket (key 34) with two cap screws (key 37) centered in
the slots of the stem bracket. Tighten the cap screws slightly.
5. On the transmitter, install the pickup pin into the lever assembly (key 30) in the position to match the application.
Refer to table 3 and figure 15.
6. Temporarily connect the 24 volt DC power supply to the instrument as indicated in figure 4.
7. Perform the potentiometer alignment procedures before mounting the transmitter on the actuator. To simulate
mid‐stroke position in step 4 of the procedure, move the lever assembly (key 30) until its center line is parallel with
the center line of the operating arm (key 25). After completing step 9 of the potentiometer alignment procedure,
remove the 24 volts DC, and continue the actuator mounting procedure as described in the following steps.
8. Stroke the actuator to the mid position of the valve travel.
9. Fit the pickup pin, located in the lever assembly (key 30), into the horizontal slot in the stem bracket (key 33). Bolt
the mounting plate (key 21) to the actuator with cap screws, washers, and spacers (keys 23, 24, and 22) using the
two tapped holes in the side of the actuator yoke.
10. Use the mounting plate slots, which allow the lever assembly (key 30) and the operating arm (key 25) to be nearly
parallel, and position the long edge of the mounting plate parallel with the actuator stem. Tighten the bolts
securely.
11. Loosen the two cap screws (key 37) connecting the stem bracket (key 33) to the stem mounting bracket (key 34).
Manually move the lever assembly (key 30) until its center line is parallel with the center line of the operating arm
(key 25).
12. Tighten the two cap screws (key 37) in the slotted holes.
13. Stroke the actuator to ensure that full travel is allowed.
14. Perform the electrical connection and direct and reverse action procedures.
15. Verify potentiometer alignment by performing the potentiometer alignment procedure.
Rotary‐Shaft Actuator Mounting; 4210, 4211, 4212, and 4215 Transmitters
Use the following general procedures and figures 19, 20, and 21 to mount the transmitter on rotary‐shaft actuators.
Refer to figure 19 for key number locations for this example.
1. Install the transmitter on the mounting plate (key 21) with two cap screws (key 32). The transmitter can be
mounted in any of four positions on the bracket. Tighten the cap screws slightly.
2. On the actuator, attach the coupler plate assembly (key 57) and travel indicator to the actuator shaft. This is
accomplished by removing two self‐tapping screws and travel indicator and replacing them with the self‐tapping
screws and coupler plate assembly furnished with the transmitter for the mounting application.
