OpenAir™ GLB Enhanced Non-Spring Return Rotary Electronic Damper Actuator
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.
1. Connect all wires per Figure 22.
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°.
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.
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.
