shaft. Pull the hex key to the RIGHT SLOWLY until you hear a "click" from
the associated (#1) cam switch and snug up on the cam setscrew. Do not
move the actuator. No need to overtighten the cam setscrew.
5. Set the CCW auxiliary switch.
a. Using the 2.5mm hex key on CAM #3 (Fig 7) loosen the cam set
screw and rotate the cam CCW by pushing the hex key to the RIGHT
a few degrees. Lightly snug up on the set screw until resistance is felt
against the cam shaft. Pull the hex key to the LEFT SLOWLY until you hear
a "click" from the associated (#3) cam switch and continue a few more
degrees in the same direction. (This assures the AUX switch trips before
the actuator reaches its end of travel. Snug up on the cam setscrew.
6. Set the signal processing for the actuator. (ref Fig 8)
Use the table below to set the eight (8) DIP switches to establish signal
type, response and fault modes of operation.

7. Set the signal response. (ref Fig 8) Remove power. Manually position the
actuator to about 50% open, and then re-apply power. The actuator will travel
in a CW direction until it reaches its full CW end of travel position (set by cam#2
in step 4 above). Press and hold the "SET" button on the logic PCB for 2 seconds.
The PCB will enter local setting mode. LED9 will illuminate.
- Press and hold the "UP" button until the actuator reaches it full OPEN (CCW)
position (LED 2 ON), and generate a 20mA signal. Press the "MODE" button for 2
seconds to set the full CCW position.
- Press and hold the "DN" button until the actuator reaches it full CLOSED (CW)
position (LED 1 ON), and generate a 4mA signal. Press the "MODE" button for 2
seconds to set the full CW position.
- Check the feedback (4mA) and adjust VR2 if necessary. Turning VR2 CW
decreases the feedback value. Turning VR2 CCW increases the feedback value.
- The 20mA feedback value is generated by the microprocessor and is not
adjustable.
- Press the "SET" button to SAVE these settings.
8. After setting the analog response, check the operation of the actuator in
response to your input signals to make sure operation is as intended. After
verification that all settings are correct, generate a 4mA input signal to drive
the actuator to its full CW position, and wait for it to stop.
9. Set the CW mechanical stop. (Fig 9) Use the 5mm hex key on the RIGHT side
stop screw and turn it clockwise until it bottoms out against the internal stop
boss on the final output drive. Turn the hex key ONE turn CCW, then use the
17mm box wrench to lock the stop screw in positon. Do not tighten the stop
screw so hard as to crush the sealing washer.
10. Generate a 20mA input signal to drive the actuator to its full CCW position,
and wait for it to stop.
11. Set the CCW mechanical stop. (Fig 10) Use the 5mm hex key on the LEFT
side stop screw and turn it clockwise until it bottoms out against the internal
stop boss on the final output drive. Turn the hex key ONE turn CCW, then use
the 17mm box wrench to lock the stop screw in positon. Do not tighten the stop
screw so hard as to crush the sealing washer.
When the actuator reaches its end of travel electrically, you should be able
to rotate the handwheel at least 1/2 or more turns before you reach the
mechanical stop. This is true for both ends of travel. If the handwheel is "locked",
the mechanical stops have been set incorrectly and must be reset. Any time the
EOT cams need to be moved, the mechanical stops MUST be reset.
This completes the calibration of the actuator.
