1. Check the Operation:
a. Connect wires 1 (red), 6 (violet), and 7 (orange) to the actuator.
b. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
c. Allow the actuator shaft coupling to rotate from 0 to 90°.
d. Stop applying a control signal to wires 1 (red) and 6 (violet).
e. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange).
f. Allow the actuator shaft coupling to rotate from 90 to 0°.
2. Check the Feedback:
a. Set the DMM dial to ohms.
b. Connect wires P1 and P2 to the DMM. The DMM should indicate a resistive
value.
c. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
The reading of the DMM should increase.
d. Stop applying a control signal to wires 1 (red) and 6 (violet).
e. Connect wires P2 and P3 to the DMM. The DMM should indicate a resistive
value.
Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange). The reading of the DMM
should increase.
3. Check the Auxiliary Switch A:
a. Set the DMM dial to ohms (resistance) or continuity check.
b. Connect wires S1 and S3 to the DMM. The DMM should indicate an open circuit
or no resistance.
c. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch A.
d. Stop applying a control signal to wires 1 (red) and 6 (violet).
e. Connect wires S1 and S2 to the DMM. The DMM should indicate an open circuit
or no resistance.
f. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange).
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch A.
4. Check the Auxiliary Switch B:
a. Set the DMM dial to ohms (resistance) or continuity check.
b. Connect wires S4 and S6 to the DMM. The DMM should indicate an open circuit
or no resistance.
c. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch B.
d. Stop applying a control signal to wires 1 (red) and 6 (violet).
e. Connect wires S4 and S5 to the DMM. The DMM should indicate an open circuit
or no resistance.
f. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange).
The DMM should indicate contact closure as the actuator shaft coupling
reaches the setting of switch B.
