24 Vac Floating Control

Operation

A floating control signal controls the damper actuator. The actuator’s angle of rotation is proportional to the length of time the signal is applied. A 24 Vac control signal to wires 1 and 6 (G-Y1) causes the actuator coupling to rotate clockwise. A 24 Vac control signal to wires 1 and 7 (G-Y2) causes the actuator coupling to rotate counterclockwise.

To reverse the direction of rotation, the wires 6 and 7 (Y1 and Y2) can be interchanged. In the event of a power failure or with no control voltage, the damper actuator holds its

position.

Life expectancy

Auxiliary switches

GDE/GLB136.1P

Sizing

An improperly tuned loop will cause excessive repositioning that will shorten the life of the actuator.

NOTE: The auxiliary switch setting shafts rotate with the actuator. The scale is valid

only when the actuator is in the "0" position on clockwise motion. Use the long arm of the

† to point to the position of switch A. Use the narrower

tab on the red ring to point to the position of switch B.

The type of actuator required depends on several factors.

1. Obtain damper torque ratings (ft-lb/ft

or Nm/m2) from the damper manufacturer.

2. Determine the area of the damper.

3. Calculate the total torque required to move the damper:

Total Torque =

4. Select the actuator type from Table 2.

Safety Factor: When determining the torque of an actuator required, a safety factor should be included for unaccountable variables such as slight misalignments, aging of the damper, etc. A suggested safety factor is 0.80 (or 80% of the rated torque).

Wiring

All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers. The sum of the VA ratings of all actuators and all other components powered by one

transformer must not exceed the rating of the transformer. It is recommended that one transformer power no more than ten actuators.

CAUTION:

Do not wire different types of actuators (such as GBBx or GIBx) in parallel with the GDE13x or the GLB13x models.

WARNINGS:

All six outputs of the dual auxiliary switch (A and B) must only be connected to:

• Class 2 voltage (UL/CSA).

• Separated Extra-Low Voltage (SELV) or Protective Extra Low Voltage

(PELV) (according to HD384-4-41) for installations requiring conformance. You must use a

Installations requiring

• All wiring for CE certified actuators must be "Separated Extra Low Voltage" (SELV) or "Protective Extra Low Voltage" (PELV) per HD384-4-41.

• Use safety-isolating transformers (Class III transformer) per EN61558. They must be rated for 100% duty cycle.

• Over current protection for supply lines is maximum 10A.

Direction of Damper Rotation

If the damper blades turn counterclockwise to open (CCW), reverse the 6 (violet) and 7 (orange) wires at the controller.

Strain Relief

Securing the wires/cabling will prevent breakage and ensure strong signals to the GDE131.1T model. The following is recommended:

1. The open bracket to the right of the

actuator terminal strip is the strain relief for the customer provided control wires.

2. Secure the wires to the actuator bracket with a cable tie as shown in Figure 19.

The GDE131.1N has two sets of identical contacts as shown in Figure 20.

• All wiring must conform to NEC and local codes and regulations.

• Use earth ground isolating step-down Class 2 transformers. Do not use

autotransformers.

• Determine the supply transformer rating by summing the total VA of all actuators used. It is recommended that one transformer power no more than 12 actuators.

Direction of Damper Rotation

To change the direction of rotation of the GDE131.1N, switch the Y1 and Y2 wires at the controller.

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.

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.

6. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange). The DMM should indicate contact closure as the actuator shaft coupling reaches the setting of switch A.

Page 14 Siemens Building Technologies, Inc.

Check the 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 an open circuit or no resistance.

3. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet). The DMM shoul d indicate contact closure as the actuator shaft coupling reaches the setting of switch B.

4. Stop applying a control signal to wires 1 (red) and 6 (violet).

5. Connect wires S4 and S5 to the DMM. The DMM should indicate an open circuit or no resistance.

6. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange). The DMM should indicate contact closure as the actuator shaft coupling reaches the setting of switch B.
