Operation
GBB/GIB13x
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.
If you want to reverse the direction of rotation, wires 6 and 7 (Y1 and Y2) may be
interchanged. Reverse the position indicator so that the counterclockwise 0 to 90 scale
is visible. See Figure 16.
In the event of a power failure or with no control voltage, the damper actuator holds its
position.
In the event of a blockage in the damper, the actuator is overload protected over the full
range to prevent damage to the actuator.
Life expectancy An improperly tuned loop will cause excessive repositioning that will shorten the life of
the actuator.

Sizing The number of actuators required depends on several factors. To determine the
quantity of actuators required for the installation:
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 = Torque Rating × Damper Area
4. Select the total quantity of actuators required:
Number of actuators = ions)Specificatto(ReferTorquetorx ActuaSF
requiredTorqueDamperTotal
1
1Safety Factor: When calculating the number of actuators 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).
Mechanical coupling of the actuator is allowed if:
1. The same type of actuator is used.
2. The power trunk can handle added components.
3. The same power and control inputs go to both actuators (parallel wiring).

• The actuator must be placed on the damper shaft so that the front of the actuator is
accessible. The label and the manual override button are the front side.
• The minimum damper drive shaft length is 3/4-inch (20 mm). The shaft length
determines whether the shaft adapter will be mounted on the front or back side of
the actuator.
• See Specifications for minimum and maximum damper shaft dimensions.
• Mount the position indicator to show either the clockwise or counterclockwise 0 to
90 scale.
• A mounting bracket is included with the actuator.
- Detailed mounting instructions are included with each actuator.
- The shaft adapter and mounting parts are shipped in a separate container with
the actuator.
• The actuator is shipped from the factory with a 5° pre-load to ensure tight close off
of the damper.

Manual override To move the damper blades and
lock the position with no power
present:
1. Determine damper rotation:
clockwise or counterclockwise.
2. Hold down the PUSH button.
3. Make adjustments to the damper
position.
4. Release the PUSH button.
Once power is restored, the actuator
returns to automated control.
Figure 14. Manual Override.
Mechanical range
adjustment
The angular rotation is adjustable between 0 and
90° at 5-degree intervals. The range of shaft
movement is limited by mounting the shaft
adapter:
Begin by loosening the shaft adapter from the
damper shaft and remove the actuator from the
damper shaft.
1. Remove clip.
2. Remove shaft adapter from the actuator.
