Optional Valtek Rotary Mounting Procedure; Tubing Positioner To Actuator - Flowserve Logix 3200MD Installation, Operation And Maintenance Manual

®
NOTE: The take-off arm should be snug enough to hold the fol-
lower 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 QUICK-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 QUICK-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 RGGY 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.

WARNING: Failure to follow this procedure will result
in positioner and/or linkage damage. Check air-action
and stroke carefully before lockdown of take-off arm to
spline lever adapter.
5.3 Optional Valtek Rotary
Mounting Procedure
The optional rotary mounting applies to Valtek valve/actuator assem-
blies that are equipped with mounted volume tanks or handwheels.
The optional mounting uses a four-bar linkage coupled to the valve
shaft. The following tools are required:
• ⁄ " open-end wrench

8
• ⁄ " open-end wrench
7
16
• 1/2" open-end wrench

3. Attach follower arm to positioner feedback shaft, using the star

5. Thread ball joint linkage end to tripper and tighten (thread
6. Tighten bracket and tripper bolting.
7. Check for proper operation, note direction of rotation.
5.4
The Logix 3200MD digital positioner is insensitive to supply pres-
sure changes and can handle supply pressures from 30 to 150 psig.
A supply regulator is recommended if the customer will be using
the diagnostic features of the Logix 3200MD but is not required. In
applications where the supply pressure is higher than the maximum
(See Figure 5)
actuator pressure rating a supply regulator is required to lower the
pressure to the actuator's maximum rating (not to be confused with
operating range). An air filter is highly recommended for all applica-
tions where dirty air is a possibility.
NOTE: The air supply must conform to ISA Standard ISA 7.0.01 (a
dew point at least 18°F below ambient temperature, particle size
below five microns—one micron recommended—and oil content
not to exceed one part per million).
bracket to actuator transfer case pads. Leave bracket loose to
allow for adjustment.

locates the positioner the farthest from the valve. Rotate posi-

washer and 10-32 nut.
bolts and two 1/4-20 locknuts. Leave tripper loose on shaft until
final adjustment.
locking compound such as Loctite is recommended to prevent
back threading). Adjust the length of tie rod so follower arm and
tripper rotate parallel to each other (the rod must be cut to the
desired length). Connect the other ball joint end to follower arm
using a star washer and a 10-32 nut.

WARNING: If rotating in wrong direction, serious dam-
age will occur to the positioner and/or linkage. Check
air action and stroke direction carefully before initiating
operation.
