6. Apply control signal for actuator 0% position.
(See Fig. 11 and Table 2.)
a. (0)2-10 Vdc: apply (0)2 Vdc signal to terminal 3.
b. 10-(0)2 Vdc: apply 10 Vdc signal to terminal 3.
c. (0)4-20 mA: apply (0)4 mA signal to terminal 3.
d. 20-(0)4mA: apply 20 mA signal to terminal 3.
e. Floating: apply 24 Vac to appropriate 0°-90° (3) or
90°-0° (4) terminal.
7. Actuator drives to full open or full closed position.

Spring Return Operation

1. Mount actuator for required application (either clock-
wise
or counterclockwise
the damper or valve).
2. Connect power to terminals 1 and 2. (See Fig. 11 and
Table 2.)
NOTE: For two-position models skip to step 5.
3. Set "Mode Select" dial to desired control signal.
(See Fig. 4.)
4. Apply control signal for actuator 50% position.
(See Fig. 11.)
a. Vdc Input Signal: apply 5-6 Vdc signal to terminal 3.
b. mA Input Signal: apply 10-12 mA signal to terminal 3.
c. Floating: apply 24 Vac to appropriate 0°-90° (3) or
90°-0° (4) terminal until device reaches 50%.
5. Allow the actuator to drive to 50% position.
6. Disconnect wire from terminal 1.
7. Actuator spring returns to 0% position.
8. Re-connect wire to terminal 1, actuator drives back
toward 50% position.

Feedback Operation

1. Connect a multi-meter, set for Vdc, to terminals 2 and 5.
2. Apply the same signal as in step 4 of Modulating
Operation.
3. The multi-meter reading increases to match the input
signal as actuator drives towards full open or full closed
position.
4. Apply the same signal as in step 6 of Modulating
Operation.
5. The multi-meter reading decreases to match the input
signal as actuator drives towards 0% position.
