1. Connect a Digital Multimeter (DMM) to the supply voltage wires.
2. Verify that the supply voltage is between 100 and 240 Vac.
3. Turn off the power supply.
Check Operation:
1. Connect all wires per Figure 27.
2. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 6 (black).
3. Allow the actuator shaft coupling to rotate from 0° to 90°.
4. Stop applying the control signal to wires 4 (light blue) and 6 (black).
5. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 7 (white).
6. Allow the actuator shaft coupling to rotate from 90° to 0°.
Check 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 open circuit or no resistance.
3. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 6 (black). The DMM
should indicate contact closure as the actuator shaft coupling reaches the setting of
Switch A.
4. Stop supplying the control signal to wires 4 (light blue) and 6 (black).
5. Connect wires S1 and S2 to the DMM. The DMM should indicate open circuit or no
resistance.
6. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 7 (white). The DMM
should indicate contact closure as the actuator shaft coupling reaches the setting of
Switch A.
Check Auxiliary Switch B:
1. Set the DMM dial to ohms (resistance) or continuity check.
2. Connect wires S4 and S6 to the DMM. The DMM should indicate open circuit or no
resistance.
3. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 6 (black). The DMM
should indicate contact closure as the actuator shaft coupling reaches the setting of
Switch B.
4. Stop applying the control signal to wires 4 (light blue) and 6 (black).
5. Connect wires S4 and S5 to the DMM. The DMM should indicate open circuit or no
resistance.
6. Apply a control signal (100 to 240 Vac) to wires 4 (light blue) and 7 (white) The DMM
should indicate contact closure as the actuator shaft coupling reaches the setting of
Switch B.
