Terminal Strip Wiring
Connections.
1.
Check that the wires are connected correctly.
2.
Check that offset and slope are set correctly, if used.
3.
Check that the direction of rotation switch matches the rotation of the damper shaft.
4.
Connect wires 1 (red) and 2 (black) to a Digital Multimeter (DMM) with the dial set at AC
V to verify that the operating voltage is within range.
Check operation:
1.
Connect wires 1 (red) and 2 (black) to the actuator.
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 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 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.
OpenAir Non-Spring Return Rotary Electric Damper Actuator
NOTES:
The GDE161.1T does not
provide a feedback signal.
Maximum wire size 14 AWG.
The open bracket to the right
of the actuator terminal strip is
the strain relief for the
customer provided control
wires. Secure the wires to the
actuator bracket with a tie wrap
as shown in Figure 21.
