1. Check that the wires are connected correctly.
2. Connect wires 1(red) and 6 (violet) to a Digital Multimeter (DMM) with the dial
set at Vac. Apply a control signal (24 Vac) to wires 1 and 6 to verify that the
operating voltage is within range.
3. Connect wires 1(red) and 7 (orange) to a DMM with the dial set at Vac. Apply a
control signal (24 Vac) to wires 1 and 7 to verify that the operating voltage is
within range.
Check Operation:
1. Connect wire 1 (red) to the actuator.
2. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
3. Allow the actuator shaft coupling to rotate from 0 to 90°.
4. Stop applying a control signal to wires 1 (red) and 6 (violet).
5. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange).
6. Allow the actuator shaft coupling to rotate from 90 to 0°.
Check Feedback:
1. Set the DMM dial to Ohms.
2. Connect wires P1 and P2 to the DMM.
The DMM should indicate a resistive value.
3. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet).
The reading of the DMM should increase.
4. Connect wires P2 and P3 to the DMM.
The DMM should indicate a resistive value.
5. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange).
The reading of the DMM should increase.
Check the Auxiliary Switch A:
1. Set the DMM dial to Ohms (resistance) or continuity check.
2. Connect wires S1 and S3 to the DMM.
The DMM should indicate an open circuit or no resistance.
3. 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.
4. Stop applying a control signal to wires 1 (red) and 6 (violet).
5. Connect wires S1 and S2 to the DMM.
The DMM should indicate an open circuit or no resistance.
