3. Attach follower arm to positioner feedback shaft using the star
washer and 10-32 nut.
NOTE: The arm will point up when feedback shaft is in the free
position.
4. Using four 1/4-20 x 1/2" bolts, fasten positioner to universal bracket
using appropriate hole pattern (stamped on bracket).
5. Using a 1/2" end wrench and two
to actuator transfer case pad. Leave these bolts slightly loose until
final adjustments are made.
6. Rotate take-off arm so the follower pin will slide into the slot on
the take-off arm. Adjust the bracket position as needed noting
the engagement of the follower pin and the take-off arm slot. The
pin should extend approximately
properly adjusted, securely tighten the bracketing bolts.
Orienting the Take-off Arm for Final Lock Down
1. Tube the Logix 3400MD positioner to the actuator according to the
instructions given in Section 5.5, "Tubing Positioner to Actuator."
2. With supply pressure off, rotate the follower arm in the same
direction the shaft would rotate upon a loss of supply pressure.
When the mechanical stop of the follower arm (positioner) is
reached, rotate back approximately 15 degrees.

3. Hold the take-off arm in place; tighten the screw of the take-off arm.
NOTE: The take-off arm should be snug enough to hold the follower
arm in place but allow movement when pushed.
4. Connect regulated air supply to appropriate port in manifold.
5. Remove main cover and locate DIP switches and RE-CAL
button.
6. Refer to sticker on main board cover and set DIP switches
accordingly. (A more detailed explanation of the DIP switch
settings is given in Section 7, "Startup.")
7. Press the RE-CAL button for three to four seconds or until the
positioner begins to move. The positioner will now perform a
stroke calibration.
8. If the calibration was successful the green LED will blink GGGG or
GGGY and the valve will be in control mode. Continue with step 9.
If calibration failed, as indicated by a YRYR or YRRY blink code, the
A/D feedback values were exceeded and the arm must be adjusted
away from the positioners limits. Return to step 2 and rotate the
arm back approximately 10 degrees.
NOTE: Remember to remove the air supply before re-adjusting
take-off arm.
