Modulating
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 0 position.
Life expectancy
An improperly tuned loop will cause excessive repositioning that will shorten the life of
the actuator.
Control signal
GDE163.1P and GDE164.1P: For sequencing and the electronic limitation of the angle
adjustment
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.

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.
