Rather, the SmartAct actuator does this automatically when the min. 5); the feedback signal is likewise autoadapted.

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. 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. If necessary, limit the stroke to the desired range using the mechanical end limits. Drive the actuator to the left end limit (totally counterclockwise) by setting the control signal as specified in Table 1. 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. 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). Voltage/Current Control Signal Selection Dip Switch In its default shipping position, the voltage/current control signal dip switch (see Fig. Setting it to ON results in current control. Position Indication autoadapt dip switch for normal operation (ON) voltage/current control signal dip switch (OFF) The hub adapter indicates the rotation angle position by means of the rotational angle scales (0. . . 90° / 90. . . 0°). 60 30 0 90 90 60 30 0 Fig. Dip switches (view with PCB at bottom) Fig. Position indication 3 EN0B-0341GE51 R0409 SmartAct N20010, N34010 Manual Adjustment CORRECT INCORRECT 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).

The internal auxiliary switches are field-installable parts providing two SPDT freely-adjustable switches. Access Cover Kit Order no. : WB20 For M20 outlets. Contains: · 1 access cover (with screw) · 2 cable connectors · 2 dust-protection caps SPARE PARTS Spare Parts Kit Order no. : A7209. 2071 The spare parts kit contains the following items: Fig. 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.
