Figure 16: Driver Module Barbed Fitting
16. Verify 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 13 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 in 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 clock wise 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
15. Seal around the screw using an RTV sealant.
20. Insert a driver-to-housing screw into the driver housing through the counterbored hole in the 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.
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 As-
sembly.
24. Verify that the three O-rings (item 35) are in the counter bores on the machined platform where the spool
valve block is to be placed (Figure 24).
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
15). Slide the block toward the driver module until the two retaining holes line up with the threaded holes in
the base.
