Automax Logix 3200IQ Digital Positioner
Installation, Operation and Maintenance Instructions
3. Remove the main cover.
4. Remove the plastic board cover by removing the three
retaining screws (see Figure 18).
5. Disconnect the position sensor wires from the main
PCB assembly.
6. Remove the two rotary position sensor-retaining
screws and lift the sensor out of the housing.
7. Turn the new position sensor shaft until the dot on the
side of the shaft is aligned with the wires on the side of
the position sensor (Figure 21).
8. Insert the position sensor into the shaft with the wires
pointing toward the main PCB assembly. Turn the
position sensor clockwise until bolting slots align with
the housing screw holes and the wires on the sensor
protrude over the main PCB assembly.
Note: Do not mix the position sensor with those from
older Logix positioners. Older models contain sensors
with different ranges that will not work in the Logix
3200IQ model. The wires on the Logix 3200IQ
position sensor are red, white and black.
9. Carefully center the position sensor on the shaft bore,
insert and tighten the screws. Do not overtighten.
10. Route the wires along the side of the position sensor
and reconnect to the main PCB assembly.
11. Install the plastic board cover. Insert the three retaining
screws through the plastic cover into the threaded
boss and tighten evenly, using a Phillips screwdriver.
Do not overtighten (see Figure 18).
12. Reinstall all covers.
13. Reconnect power and air supply to the positioner and
perform a stroke calibration.
