NOTE: For DIP switch setting options, see the
Technical Instructions listed in References.
1. To use the entire 0(2) to 10V input signal to con
trol the adjusted range, raise the tab located on
the lower left-hand side of the actuator and
locate the DIP switches. See Figure 15.
2. Set the self-adapt DIP switch (middle) to
(ON).
3. Close the tab over the DIP switches.
For example, if you set the locking screw at 70° and
turn the self-adapt switch ON, a 5V input signal will
drive the damper to 35° (50% of its adjusted range).

CAUTION
When turning the self-adaptive feature on, or after
software reset with the feature on, the actuator will
enter a five-minute calibration cycle as the actua-
tor adjusts to the rotation limits of the system. The
software reset happens after power on, or may be
caused by electrostatic discharge (ESD) at levels of
2 kV and above.
