Contents of Package
The delivery package includes the actuator itself, parts 1
through 8 (see Fig. 2), the anti-rotation bracket screws, and
the SM mounting plate and screws.
Modulating Control
The actuator is capable of being operated by several
controllers providing Vdc or mA output.
Rotary Movement
The control signal and the corresponding rotation direction
(clockwise or counterclockwise) can be selected using the
rotation direction switch (see part 7 in Fig. 2), thus eliminating
the need to re-wire. To ensure tight closing of the dampers,
the actuator has a total rotation stroke of 95°.
As soon as operating power is applied, the actuator may start
to run. When power is removed, the actuator remains in
position. For actuator-controller wiring instructions, see
section "Wiring" on page 5.

* Default shipping position.
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).

Fig. 4. Dip switches (view with PCB at bottom)
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.
Fig. 5. Actuator positioning curve
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.
Position Indication
The hub adapter indicates the rotation angle position by
means of the rotational angle scales (0...90° / 90...0°).

Manual Adjustment
IMPORTANT
In order to prevent equipment damage, you must
remove power before manual adjustment.
After removing power, the gear train can be disengaged using
the declutch button, permitting the actuator shaft to be
manually rotated to any position. The feedback signal will
then follow the new position.
Limitation of Rotation Stroke
Two mechanical end limits (adjustable in 3° increments) are
provided (20 Nm [177 lb-in] models, only) to limit the angle of
rotation as desired (see Fig. 7).
Fig. 7. Mechanical end limits
The mechanical end limits must be securely fastened in place
as shown in Fig. 8. Specifically, it is important that they
properly mesh with the rotational angle scales when the
screws are tightened.
Fig. 8. Correct / incorrect tightening of end limits
Internal End Switches
NOTE: Only those actuators for which the option "-SW2"
has been specified when ordering (e.g.: "N20010-
SW2") feature internal end switches.
The internal end switches are set to change from "common"
to "normally open" at angles of 5° and 85°, respectively, from
the totally counterclockwise position.

Override
If terminal Y of the terminal strip (see section "Wiring
Diagrams" on page 6) is unplugged, the stroke will be 0%;
reversing the rotation direction using the rotation direction
switch will result in a max. stroke of 100%. If terminal Y is
jumped with terminal 1 (24 Vac), the stroke will be 50%.
INSTALLATION
These actuators are designed for single-point mounting.
IMPORTANT
In order to prevent equipment damage, you must
remove power or set the rotation direction switch to the
"Service/Off" position before manual operation.
Mounting Instructions
All information and steps are included in the Installation
Instructions supplied with the actuator.
Mounting Position
The actuators can be mounted in any desired orientation (no
IP54 if mounted upside down; see Fig. 10). Choose an
orientation permitting easy access to the actuator's cables
and controls.

Mounting Bracket and Screws
If the actuator is to be mounted directly on a damper shaft,
use the mounting bracket and screws included in the delivery
package.

Self-Centering Shaft Adapter
The self-centering shaft adapter can be used for shafts
having various diameters (10...27 mm [3/8...1-1/16"]) and
shapes (square or round).
In the case of short shafts, the shaft adapter may be reversed
and mounted on the duct side.
Stroke Limitation with Mechanical End Limits
The mechanical end limits (20 Nm [177 lb-in] models, only)
enable the stroke to be limited from 0...90° in increments of
3°.
Wiring
Connecting to the Power Supply
In order to comply with protection class II, the power source of
24 V actuators must be reliably separated from the network
power supply circuits as per DIN VDE 0106, part 101.
Access cover
To facilitate wiring the actuator to the controller, the access
cover can be detached from the actuator.
IMPORTANT
Remove power before detaching the access cover.
Once the access cover has been removed, please
take care to avoid damaging any of the parts now
accessible.
Fig. 11. Access cover (N20010-SW2)
Depending upon the model, the access cover may have one
or two terminal strips, including a layout with a description for
each of the terminals.
