5.2.2. OBJECTS FOR DYNAMIC PARAMETER CHANGES
Input 2 byte
Output 2 byte
Via object 11 (delay time) and via object 12 (brightness below which sensor is active) may be changed or read the related parameter- values directly without to re-programming the presence- detector.
This mode allows via external devices (BMS , touch screen , logic ) to influence the functioning of the presence- detector directly .
For example, dependent on user needs, the light-ON switching characteristic / delay time can be dynamically adapted during certain day times to optimize the application .
Changed values via object remain stored temporarily. After bus voltage interruption / return , after a reset or after a re- programming , the originally parameterized values are active again.
5.2.3. Object 14 CONSTANT LIGHT CONTROL - FORCED DIMMING
Input 4 bit
If the constant light control of the Presence detector is activated by a presence detection or by an external "ON"- command (obj1) , dimming values (brighter or darker ) transmitted to object 14 interrupt the function
Constant-light-control immediately and remains inactive during motion detection and or the delay- time.
At that moment, the constant-light-control output-value ( Obj 22) can with relative dimming ( brighter / darker ) by a KNX push button - to be changed .
After the delay- time or after an external " OFF " switching command , the constant-light- control is active again and operates (when motion-detection) with the stored parameter- values .

5.3. Parameters

5.3.1. Operating mode during power- on
After power -on/ bus voltage return or bus voltage interruption, the presence-detector is for the first 60sec inactive. During this stabilization-period of the electronic device, the detector doesn´t sends any telegrams too.
Dependent on the application, in the operating mode "Automatic" ,the light output (obj1/obj22) can be activated during the start-up phase.
In this mode, two options with "75s light on after restart" or "no reaction after restart" can be selected.
5.3.2. Automatic adaptation of the "light-off" threshold
With the setting „Automatic" in the parameter Brightness above which lighting is turned off, the detector, calculates automatically the light-off threshold with the following rule:
If the effective brightness with switched light-channel (after 1min.) is greater than the parameterized value „Brightness below which sensor is active", the light-off threshold is 10% increased above this value plus 200LUX.
If the effective brightness with switched light-channel (after 1min.) is below than the parameterized value „Brightness below which sensor is active", the light-off threshold is 10% increased above the actual brightness-value
(obj9) plus 200LUX.
16
The light-off threshold is recalculated after each expired delay-time and a renewed motion-detection or an "ON" switching-command.
If the parameter Brightness switch–off level is selected with a fixed value, this value needs to be higher or the same as the parameter Brightness below sensor is active.
