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.

IP54 IP54IP54 IP54

Fig. 10. Mounting for IP54

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.
