9. Connect regulated air supply to appropriate port in manifold. See
section 6 TUBING.
10. Connect the power to the 4-20 mA terminals. See section 7
ELECTRICAL CONNECTIONS.
11. Remove main cover and locate DIP switches and QUICK-CAL/
ACCEPT button.
12. Refer to sticker on main board cover and set DIP switches
accordingly. See section 8 STARTUP.
13. Press the QUICK-CAL/ACCEPT button for three to four seconds
or until the positioner begins to move. The positioner will now
perform a stroke calibration.
14. If the calibration was successful the green LED will blink GGGG
or GGGY and the valve will be in control mode.

15. If calibration fails, as indicated by a RGGY blink code, retry the
calibration. If it still fails, the feedback values were exceeded and
the arm must be adjusted away from the positioner's limits. Ro-
tate the feedback shaft so that the full free travel of the feedback
shaft is in the range of the actuator movement. Optionally, con-
tinue to attempt the calibration. Each calibration attempt adjusts
the acceptable limits and it should pass eventually.
a
CAUTION: Remember to remove the air supply before re-adjusting
take-off arm.
NOTE: If mounted properly, the follower arm should be horizon-
tal when the valve is at 50% stroke and should move approxi-
mately ±30° from horizontal over the full stroke of the valve.
NOTE: To virtually eliminate non-linearity, use the Linearization
feature on the Custom Characterization page of the DTM.
