Three-Position Control, 24 VAC/DC
1. Check that the wires are connected correctly.
2. Connect wires 1 (red) and 2 (black) to a Digital Multimeter (DMM) with the dial set at VAC to verify that the
operating voltage is within range.
3. Check operation:
a. Connect wires 1 (red) and 2 (black) to the actuator.
b. Apply a control signal (24 VAC/DC) to wire 6 (violet).
c. Allow the actuator shaft coupling to rotate from 0 to 90°.
d. Stop applying a control signal to wire 6 (violet).
e. Apply a control signal (24 VAC/DC) to wire 7 (orange).
f. Allow the actuator shaft coupling to rotate from 90 to 0°.
4. Check spring return:
a. Apply a control signal (24 VAC/DC) to wire 6 (violet).
b. Allow the actuator shaft coupling to rotate half-way.
c. Disconnect wire 1 (red).
d. The spring returns the actuator shaft coupling to the fail 0 position.
