Feedback Signal and Manual Adjustment
If, while the actuator is not rotating, the user declutches it and
manually repositions the shaft adapter, the feedback signal
will then follow the new position at which the shaft adapter
has been left.
Power OFF/ON Behavior
In case the power to the actuator fails, after re-applying
power, the actuator aknowledges its present position and
follows the signal from the controller. This makes it
unnecessary for the actuator to employ autoadaption in order
to re-map the control signal settings.
Dip Switches
The actuators are equipped with two dip switches accessible
after removing the access cover (see Fig. 4).

Autoadapt Dip Switch for Normal Operation
In its default shipping position, the autoadapt dip switch for
normal operation is set to ON as shown in Fig. 4. If it is set to
OFF, no autoadapting is performed, and the control signal
map remains constant.
The autoadapt functionality does not have to be triggered.
Rather, the SmartAct actuator does this automatically when
the min. and max. control signals are provided (see Fig. 5);
the feedback signal is likewise autoadapted.

Adjusting the Actuator for Autoadapt
In order to make use of the autoadapt functionality, proceed
as follows:
1.
Set the autoadapt dip switch to the ON position.
2.
If necessary, limit the stroke to the desired range using
the mechanical end limits.
3.
Drive the actuator to the left end limit (totally counter-
clockwise) by setting the control signal as specified in
Table 1.
4.
Drive the actuator to the right end limit (totally clockwise)
by setting the control signal as specified in Table 1. The
stroke has now been limited to 0...100% of the control
signal range.
Voltage/Current Control Signal Selection Dip Switch
In its default shipping position, the voltage/current control
signal dip switch (see Fig. 4) is set to OFF (= voltage control).
as shown in Fig. 4. Setting it to ON results in current control.
