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 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.

Sizing The type of actuator required depends on several factors.

1. Obtain damper torque ratings (ft-lb/ft2or 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 = SF eaDamper AringTorque Rat 1

4. Select the actuator type from Table 2.

1Safety 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).

You must place the actuator on the damper shaft so that the front of the actuator is

accessible. The label is on the front side.

The minimum damper drive shaft length is 3/4-inch (20 mm).

A mounting bracket is included with the actuator.

Observe the service envelope around the actuator as shown in Figure 25.

Detailed mounting instructions are included with each actuator.

Manual override To move the damper blades and lock the

position with no power present:

1. Slide the red manual override knob

toward the back of the actuator.

2. Make adjustments to the damper

position.

3. Slide the red manual override knob

toward the front of the actuator.

Once power is restored, the actuator returns

to automated control.

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 certified plenum rated actuator.

Installations requiring Conformance:

•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.

GDE131.1N

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
