Operation

A continuous 0(2) to 10 Vdc signal from a controller to wire 8 (Y) operates the damper

actuator. The angle of rotation is proportional to the control signal. A 0 to 10 Vdc position

feedback output signal is available between wire 9 (U) and wire 2 (G0) to monitor the

position of the damper motor.

In the event of a power failure, the actuator holds its position. In the event that only the

control signal is lost, the actuator returns to the 0position.

Life expectancy

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

the actuator.

Control signal

adjustment

GDE163.1P and GDE164.1P: For sequencing and the electronic limitation of the angle

of rotation.

Use the Uo potentiometer to set the offset (start point) between 0 to 5 Vdc.

Use the U potentiometer to set the slope (span) between 2 to 30 Vdc.

NOTE: The Y input is limited to a maximum of 10 Vdc. If the sum of the offset and

slope setting is greater than 10V, the angle of rotation is reduced providing the

feature of electronic limitation of the angle of rotation.

To change the control signal from the factory setting (0 to

position.

Self-adapt Switch

Figure 17.

OFF Position

(Factory Setting).

The factory setting is 0(OFF).

When mechanical angle of rotation is limited, the self-adapt

switch (middle DIP switch) may be turned ON so that the

limited range will become the new 0 to 100% for the

actuator logic. In this case, 0 to 100% is not equal to 90°

CAUTION:

When turning the self-adaptive feature on or

after the software reset with the feature on, the

actuator will enter a five-minute calibration

cycle as the actuator adjusts to the rotation

limits of the system. A software reset happens

after power on or may be caused by

electrostatic discharge (ESD) at levels of 2kV

and above.

The self-adapt capability will scale the control signal

selected, either a 0 to10 Vdc or a 2 to 10 Vdc signal, within

the adjusted mechanical range. The feedback signal will

also reflect the control signal selected, either a 0 to 10 Vdc

or a 2 to 10 Vdc.

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



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, and so on. A suggested

safety factor is 0.80 (or 80% of the rated torque).

4. Select the non-spring return actuator type from Table 3.
