Figure 12. Direction of Rotation Switch.
The factory setting is clockwise.
The direction of rotation switch should match the damper rotation movement.
Raise the protective cover from left to right to locate the DIP switches. See
Figure 8 for the location of the cover.
To change the control signal from the factory setting (0 to
10 Vdc), move the first DIP switch to the UP (2-10)
position.

0-10 Vdc 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
limited range will become the new 0 to 100% for the
actuator logic. In this case, 0 to 100% is not equal to 90°

OFF Position
(Factory Setting).
The self-adapt capability will scale the control signal
selected, either a 0 to 10 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.
Clockwise
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.
