Function

System information

This device is a product of the KNX system and corresponds to the KNX guidelines. Detailed specialised knowledge obtained from KNX training courses is required for understanding. The planning, installation and commissioning are carried out with the help of KNX-certified software.

Start up system link

The function of the device is software-dependent. The software is to be taken from the product database. You can find the latest version of the product database, technical descriptions as well as conversion and additional support programmes on our website.

Start up easy link

The function of the device is configuration-dependent. The configuration can also be done using devices developed specially for simple setting and start-up.

This type of configuration is only possible with devices of the easy link system. easy link stands for easy, visually supported start-up. Preconfigured standard functions are assigned to the in/outputs by means of a service module.

Automatic mode

The device detects heat motion caused by people, animals, or objects.

Channel lighting:
A presence command is triggered if movements are detected in the detection area and the set brightness threshold is undershot. Each detected movement restarts the set delay time. After the delay time has elapsed, a presence command is transmitted.

Channel monitoring signal mode:
A presence command is triggered independent of the brightness if motions are detected in the detection area. Each detected movement restarts the delay time. After the delay time has elapsed, a presence command is transmitted. The delay time is 1 minute and can be changed exclusively via the application software in the ETS.

Alternatively, the selection can be locked via the application software. The button does not have any function then.

• Keep button (7) pressed for more than 15 seconds until the green status LED (8) is flashing.
  The button is locked.

or if the button is locked:

• Keep the button pressed for more than 15 seconds, until the green status LED (8) is flashing.
  Selection of the operating mode via the button is possible again.

Activating/interrupting party function

The party function switches the lighting on for 2 hours. During this time no extension unit commands are executed.

In the case of motion detectors on extensions, activating the party function causes cyclical transmission of the switch-on pulse every 10 s. However, the light is only switched on when the brightness threshold is undershot at the main unit.

• Keep the button (7) pressed for more than 5 seconds, until the status LED (8) is flashing red (Fig. 3).
  The lighting is switched on for 2 hours. During this time the status LED is flashing red. Upon elapse of 2 hours, the motion detector switches to Automatic operation mode.
• Briefly press the button.
  The party function will be interrupted, the motion detector returns to Automatic mode.

Activating/deactivating presence simulation

During operation, the motion detector counts the motion detections in one full hour and saves the result. With active presence simulation at the beginning of the hour with the most detections saved, the light will be switched on for the duration of the delay time, even no motion is detected.

During the presence simulation, presence detection and extension unit commands will continue to be executed normally.

The presence simulation cannot be activated via an extension unit.

• Keep the button pressed for more than 20 seconds, until the status LED (8) is slowly flashing red (Fig. 3).
  The presence simulation is active. During this time the status LED (8) lights orange. The motion detector switches the lighting on at the saved time.
• Briefly press the button.
  The presence simulation will be disabled, the motion detector returns to Automatic mode.

Information for electricians. Installation and electrical connection

Selecting installation location

• Note recommended installation height of 1.1 m.
• Observe the motion orientation: a distinction is made between "direct approach" and "transverse motion". Motions transverse to the motion detector can be detected better than motions toward the motion detector (Fig. 6).
• Select an installation location that is free of vibration. Vibrations can cause undesired switching.
• Avoid sources of interference in the detection area (Fig. 4). Sources of interference, e.g. heating elements, ventilation systems, air conditioners and lamps that are cooling down can cause undesired switching (Fig. 7).

To avoid disturbing influences, the detection angle can be restricted (see Restriction of the detection area).

Connecting and installing the device

• Mount the supporting ring (1) to a wall box in the correct position.
• Run the bus cable with the connecting terminal through the frame (2) and connect it to the motion detector module (3) at the back.
• Attach the motion detector module (3) with the frame (2) to the supporting ring until the fastening brackets (6) engage.
• Fix dismantling protection with screw (5) if necessary.
• After start-up, click the design cover (4) into place on the motion detector module.

Start-up

Overview of operation and adjustment elements

8. Status LED
9. Response brightness potentiometer
10. Potentiometer for delay time
11. Sensitivity potentiometer
12. Detection angle adjuster

Setting the detection area

The detection angle can be restricted for the right side and for the left side via each adjuster (Fig. 8, 12) between 45°... 90°. Thus, the detection angle can be between 90° and 180° (Fig. 5).

• „Use the adjusters to set the detection angle for each side.

Setting the detection performance

Test mode must be used to test the detection performance. In test mode, the motion detector works independent of brightness. Each detection switches the lighting and status LED on for 1 second. Thereafter motion detection will be deactivated for 2 seconds.

The motion detector is connected and ready for operation.

• To do this, set the response brightness potentiometer (Fig. 8, 9) to TEST.
• Leave the detection area and observe the switching behaviour.
  If the motion detector switches on without motion in the detection area, then sources of interference (see Installation location) are present or the sensitivity is set too high.
• Reduce the sensitivity if necessary and blank out sources of interference by adjusting the detection angle or removing them.
• Check the detection area using a detection test and adjust if necessary.

Test mode ends if no movement is detected for 3 minutes or a brightness value is set.

If the detection area of a motion detector is too small, it can be extended by using several motion detector modules with Master-slave programming.

Setting the response brightness

The response brightness is the brightness value saved in the motion detector; when this value is undershot the motion detector transmits a presence command if movements are detected. The setting can be adjusted continuously within the range from 5 to 1000 Lux, Test stands for brightness-independent triggering.

• „Turn the response brightness potentiometer (Fig. 8, 9) to the desired position.

To save the current ambient brightness as response brightness, use the Teach-In function (see Setting the response brightness automatically).

Saving response brightness automatically (Teach-In function)

The Teach-In function saves the current ambient brightness automatically as the response brightness.

• Keep the button (7) pressed for more than 10 seconds, until the orange status LED (8) is flashing.
  The motion detector detects the current ambient brightness and saves it as response brightness.

The brightness saved via Teach-In is active until a change occurs via the potentiometer or application software.

Setting the delay time or pulse encoder mode

The delay time is the period of time saved in the motion detector which is the shortest time that the lighting is switched on for when the response brightness is undershot and motion is detected.
The delay time can be set to pulse encoder mode or to the defined values 10 s, 1 min., 3 min. (factory setting), 10 min. and 30 min. Inbetween those values the setting is infinitely variable.
The pulse encoder mode is used to actuate the timer function of actuators, for example. Here, the lighting channel is switched on briefly when the response brightness is undershot and a motion is detected. Afterwards, the motion detection is locked in the basic setting for 10 s.

• „Turn the delay time potentiometer (Figure 8, 10) to the desired position.

The pulse encoder mode and locking duration can also be set via the application software in the ETS (timer mode).

Note that lights can be worn down due to frequent switching with very short delay times.

Setting the sensitivity

Detection is factory-set to maximum sensitivity. If there are frequent incorrect detections, the sensitivity can be reduced.

• „Turn the sensitivity potentiometer (Fig. 8, 11) to the desired position.
