OpenAir™ GLB Enhanced Non-Spring Return Rotary Electronic Damper Actuator
Start-Up/
Commissioning
24 Vac/dc
Two-position/
Modulating
GLB16x
1.
Connect a Digital Multimeter (DMM) to the supply voltage wires.
2.
Verify that the supply voltage is between 19.2 and 28.8 Vac/dc.
3.
Turn off the power supply.
Check operation:
1.
Connect all wires per Figure 26.
2.
Set the DMM dial to Vdc.
3.
Connect wires 2 (black) and 8 (gray) to the DMM.
4.
Apply a full-scale input signal (10 Vdc) to wire 8 (gray).
5.
Allow the actuator shaft coupling to rotate from 0° to 90°.
6.
Disconnect wire 8 (gray) and the shaft coupling returns to the 0 position.
Check Feedback:
1.
Set the DMM dial to Vdc.
2.
Attach wires 2 (black) and 9 (pink) to the DMM.
3.
Apply a full-scale input signal to wire 8 (gray). The reading at the DMM should increase.
4.
Remove the signal from wire 8 (gray). The reading at the DMM should decrease and the
actuator shaft coupling returns to the 0 position.
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 full-scale input signal to wire 8 (gray). The DMM should indicate contact closure
as the actuator shaft coupling reaches the setting of Switch A.
4.
Connect wires S1 and S2 to the DMM. The DMM should indicate open circuit or no
resistance.
5.
Stop the signal to wire 8 (gray). 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 full-scale input signal to wire 8 (gray). The DMM should indicate contact closure
as the actuator shaft coupling reaches the setting of Switch B.
4.
Connect wires S4 and S5 to the DMM. The DMM should indicate open circuit or no
resistance.
5.
Stop the signal to wire 8 (gray). The DMM should indicate contact closure as the
actuator shaft coupling reaches the setting of Switch B.
