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