Installation, Operation and Maintenance Instructions
15. Remove the barbed fitting from the side of the new
driver module using the 1/4" nutdriver.
16. Verify that the O-ring is in place on the top of the new
driver module. Lay the wires back along the side of the
driver module as shown in Figure 14 and hold the
wires in position by hand.
17. Gently insert the driver module into the driver module
compartment in the housing. Turn the driver module
clockwise to thread it into the housing. Continue
rotating the driver module until it bottoms out.
18. Once the driver module has bottomed out so that the
threads are fully engaged, rotate the driver module
counter clockwise until the flat on the driver module
and the flat on the housing are aligned. This will align
the screw hole for the next step.
19. Verify that the nylon gasket is in the counter bore in
the driver module retaining screw hole as shown in
Figure 16.
20. Insert a driver-to-housing screw into the driver housing
through the counterbored hole in positioner main
housing. Tighten with a Phillips screwdriver.
21. Reach through the main compartment into the driver
module compartment of the positioner and install the
barbed fitting on the side of the driver module using
the 1/4" nutdriver.
NOTE: Do not mix the barbed fitting with those from
older Logix positioners. Older models contain orifices
that will not work in the Logix 3200IQ model. Orifices
are brass-colored, barbed fittings are silver-colored.
22. Reconnect the flexible tube coming from the regulator
to the barbed fitting.
23. Feed the driver module wires into the main chamber
of the housing, and connect them to the main PCB
Assembly.
24. Verify that the three O-rings are in the counterbores on
the machined platform where the spool valve block is
to be placed (Figure 28).
25. Carefully slide the spool into the connecting clip on the
top of the driver module assembly.
26. Carefully slide the block over the spool, using the
machined surface of the housing base as a register
(Figure 16). Slide the block toward the driver module
until the two retaining holes line up with the threaded
holes in the base.
27. Install two spool-valve screws and tighten securely
with a Phillips screwdriver (see Figure 16).
28. Slide the spool valve cover assembly over the spool
valve until the tang engages into the housing slot.
Install spool valve cover screw and tighten securely
(see Figure 15).
29. Install the plastic board cover. Insert the three retaining
screw through the plastic cover into the threaded boss
and tighten evenly, using a Phillips screwdriver. Do not
overtighten (see Figure 18).
30. Reconnect power and air supply to the positioner and
perform a stroke calibration.
31. Reinstall all covers.
Regulator
The regulator reduces the pressure of the incoming
supply air to a level that the driver module can use.
Replacing Regulator
To replace the regulator, refer to Figures 14 and 18 and
proceed as outlined below. The following tools are
required:
• Phillips screwdriver
• 1/4" nutdriver
WARNING: Observe precautions for handling
electrostatically sensitive devices.
1. Make sure valve is bypassed or in a safe condition.
2. Disconnect the power and air supply to the unit.
3. Remove the main cover.
4. Remove the plastic board cover by removing the three
retaining screws (see Figure 18).
5. Remove the five wire connections from the main PCB
assembly (six wire connections if the unit is equipped
with the 4-20 mA analog output option).
6. Remove the retaining screw from the main PCB
assembly and lift the main PCB out of the housing.
7. Remove the four screws from the regulator base.
Verify that as regulator is removed, the O-ring and filter
remain in the counter-bore (please see Figure 14).
8. Remove tubing and barbed fitting from the regulator
base.
9. Install barbed fitting and tubing to the new regulator.
10. Verify O-ring and filter are in the counterbore. Install
new regulator using 8-32 x 1/2" screws.
NOTE: Do not mix the regulator with those from older
Logix positioners. Older models contain regulators
with different settings that will not work in the Logix
3200IQ model. The regulator pressure setting is
printed on the top of the regulator. The Logix 3200IQ
regulator is set to 17.4 psig.
