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 5 ⁄
16
-18 x 1/2" bolts, attach bracket 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
1 ⁄
16
" past the take-off arm. When properly adjusted,
securely tighten the bracketing bolts.
Orienting the Take-off Arm for Final Lock Down
1. Tube the Logix 3400IQ 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.
9. Tighten the nut on the take-off arm. The socket head screw of the take-off arm must be tight,
about 40 in-lb.
NOTE: If the take-off arm slips, the positioner must be recalibrated.
