Mounting To Rotary Namur (Automax) Valves - Flowserve Logix 520MD+ User Instructions

9. 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.
10. If the calibration was successful the green LED will blink GGGG
or GGGY and the valve will be in control mode.
11. 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.
5.5 Mounting to Rotary NAMUR (AutoMax) Valve
1. Attach the mounting plate to the positioner using 4 screws. See
Figure 17.
2. Rotate the feedback shaft to match the orientation of the receiver
on the actuator.
NOTE: The feedback shaft has a clutch mechanism that allows
for over-rotation of the shaft for easy adjustments.
3. Mount the positioner onto the actuator using the washers and
nuts. See Figure 18.
4. Connect regulated air supply to appropriate port in manifold. See
section 6 TUBING.
5. Connect the power to the 4-20 mA terminals. See section 7
ELECTRICAL CONNECTIONS.
6. Remove main cover and locate DIP switches and QUICK-CAL/
ACCEPT button.

7. Refer to sticker on main board cover and set DIP switches
accordingly. See section 8 STARTUP.
8. 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.
9. If the calibration was successful the green LED will blink GGGG
or GGGY and the valve will be in control mode.
10. If calibration fails, as indicated by a RGGY blink code, retry the
calibration. If it still fails, remove power from the positioner,
disconnect the air, and remove the positioner from the actuator.
Rotate the feedback shaft so that the full free travel of the feed-
back shaft is in the range of the actuator movement. Optionally,
continue 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
s
take-off arm.
