Prevention of erroneous lighting restarts if:
•light bulbs are cooling down
•room is deserted after switching off with a KNX switch.
Cyclical transmission| If the light channel is in switching mode, it is possible to cyclically transmit the ‘ON” mode. The interval time for cyclical transmission can be set from 1 second to 4 hours.

3.2.1. Light – Preset Dimming

Object type for output-light
Preset dimming This setting enables the standby light function. The Standby value option appears in the Light menu.
3.2.2. Light – Standby parameters

Standby values| Toggles the orientation light function between active and inactive
---|---
Standby time 1| Set orientation light 1 duration time (seconds, minutes, hours).
Standby value 1| Set light intensity in % (0…100%)
Standby time 2| Set orientation light 2 duration time (seconds, minutes, hours).
Standby value 2| Set light intensity in % (0…100%)

Standby light
If the light channel is set to preset dimming, a new menu will appear to enable the standby functionality.
There are 2 parameters for both the duration time and the light intensity (%) of the standby operation.
After the regular duration time has elapsed the standby light will turn on. With object 24 the user will then be able to select one of two presentable parameter pairs. If the object value is 0 or there was no command received yet, value pair 1 is enabled. A 1 command value will trigger pair 2.
After standby has elapsed, an OFF command will be sent on the light channel.
The motion detector will return to regular mode and standby mode will be reset.
Lock commands and forced control commands will always reset standby mode immediately.

Reset to factory calibration: This is possible at any time with the setting 110″ and thereafter the reprogramming of the detector. ‘YES’: This option opens the following two additional windows:
---|---
Al) calibration value| Head AU calibration value (at <— object 1 U) in the EIS and enter it in the window.
Attention: use type 7.001 unsigned 2 byte counter in the read/send value menu! The AD value read-out then appears in the Value received menu (e.g. 739 pulses).
Lux value| Measure reference brightness with lux meter and enter a corresponding value.
| See also a description of “AD calibration value” on §4.4 for further details.

3.6. PIR evaluation

---|---
Sensitivity setting| The sensitivity can be adjusted from 1 to 10. (1 = min, 10 = mmg The default value is 5.

Numbering of the PIR sensors

The PIR sensors 1, 2 and 3 can be enabled individually or in groups of two.
The 3 positions of the pyro detectors are visible in the above illustration.
3.7. Constant light control

3.7.1. Constant light scenes

3.8. Constant light parameters

Constant light controller| This parameter enables or disables the constant light controller.
---|---
Channel 2 for constant light control| Channel 2 can be enabled for constant light control
Active/inactive Via the output object 23 a configurable value with a fixed offset can be transmitted
Preset setpoint| The preset setpoint in lux for constant light control can be preset in the ETS. It can also be changed via objects 17 and 18 (constant light – dimming relative and constant light – dim completely).
Transmit difference| This parameter (from 1% to 100%) defines the tolerance window to be exceeded in order to send a new brightness control value.
Switching constant light control with| Switching constant light control ON/OFF can be done using three different sources:
By object 16, presence detection on the light channel or presence detection on the HVAC channel.
The time interval for cyclical transmission| Defines the cycle time interval with which the last brightness value is repeated, even if it has not exceeded the tolerance window. Cyclical transmission can also be disabled.
Switch on the brightness value| The switch-on value for the lighting can be set from 1% to 100 %.
Switch on timeout| This parameter defines the initial time delay before constant light control is started.
Offset for channel 2 *| The offset range for channel 2 can be set from -50%, 0% to +50%.
Force control during switch-on| This parameter allows the constant light controller function to be set to no reaction, minimum brightness, maximum brightness
Force control during switch-off| This parameter allows the constant light controller function to be set to no reaction, minimum brightness, maximum brightness
Time for relative dimming| This parameter allows the relative dimming time to be set. This will influence the dimming soft control.
Take over set point after| This parameter allows setting the time delay after which a new setpoint will be recognized and stored in the RAM memory.
Changed setpoint to flash memory| This parameter allows a new set point to be written to the flash memory.
Keep the changed set point| Here at Yes the changed value is stored in the RAM.
Attention: now corresponds to the new nominal value of the last new dimmed brightness!
Scene| Various lux values can be set as light scenes (light moods). These can be enabled through object 21 as well.
Dead zone| The dead zone is an area within which the actual light value can change without generating new control commands. The default value for the dead zone is 2. The lux value tolerance of the dead zone can be extracted from the table below.
Example:
Dead zone value = 2
Brightness = 500 lux
The resulting tolerance is: +/- 24 ha
This means that the actual value can change from 476 lux to 524 lux without sending new control inputs to the actuator.

• In addition to the previous constant light control channel 1 (Object 22 ) there is a second constant light control channel 2 (Object 23 ). The control signal of channel 1 ± offset value is sent to the dimming actuator for light channel 2. Internally, the control range has been extended to ± 150% in order to maintain a reasonable control range at the limits.
  That means: Offset at -50%, darkness: FF (=100%) is sent to both objects. Internally, object 1 is at 150% and object 2 at 100%. If the ambient brightness now increases, object 1 remains at 100% (150% – x), and object 2 is regulated downwards (150% – 50% – x). If the regulation now drops below 100%, object 1 will also be visibly smaller on the bus, e.g. 73%, object 2 23%. Object 1 is then regulated down to 0 and object 2 is set to the minimum value of 50%. The values for transmission difference and cyclical transmission are taken from the once-off available parameters.

FUNCTIONAL BLOCKS

The functionality of the presence detector can be split up into the following blocks:

• Motion detection
• Brightness measuring
• Light control channel Switching
• Light control channel preset dimming with optional standby light function
• The HVAC control channel (with presence function)
• Lighting dependent threshold switch
• 2 channel constant light control

The motion detector and the brightness sensor (lux) each work independently on the light channel and the HVAC channel.
The constant light controller receives the actual brightness value from the Lux sensor. The controller can be switched on/off by a command via object 16 or triggered by motion detection on the light or HVAC channel. After switching or recovery of the KNX bus voltage, the presence detector usually generates a switch-on procedure.
4.1. Light control channel
The light control channel has two operating modes that can be selected via the detector operating mode parameters.
The possible settings are:

• fully-automatic
• semi-automatic

The differences between the fully-automatic and semi-automatic modes are:

• the fully-automatic mode has three operating conditions: ready, active, and passive
• the semi-automatic mode has two operating conditions: ready and active
• the semi-automatic mode does not switch the light on after motion has been detected.

Lighting can only be switched on manually by an external KNX switch.
4.1.1. OBJECT 0 OUTPUT – LIGHT – SWITCH
Output 1 bit
After each detected motion this output sends an “ON” command and starts the delay timer
The delay time can be set with a parameter delay time from 1 second to 4 hours.
At the end of the programmed time interval, an “OFF” command is sent to the output (object 0).
4.1.2. OBJECT 0 OUTPUT – LIGHT – COMPLETE DIMMING
Output 1 byte
This mode sends preselected dim values (0% to 100%) to the output for objective value for ON and for objective value for OFF respectively.
4.1.3. OBJECT 0 OUTPUT – LIGHT – SCENE
Output 1 byte
For the Objective value for ON or Objective value for OFF, one of 32 scenes can be selected respectively.
4.1.4. OBJECT 1 EXTERNAL SWITCHING / STATUS – LIGHT – SWITCH
Input 1 Bit
Input object 1 external switch/status can be used in two different ways:

• As input for an external push button that directly switches on the light
• As input for monitoring the status or the input of an actuator

In both cases, a received telegram „ON“ sets the detector to the ON state and an „OFF“ telegram to the ready state.
Whether commands for ON or OFF will be sent during the transitions depends on the parameter sending conditions for the external push button.
After having received an ON command, the follow-up timer starts as if a motion had been detected.
Lighting is subsequently switched off again.
After having received an OFF command the detector remains in its passive status during which it will not detect any motion. After having passed the idle time after switching off, the detector is ready again.
The idle time after switch-off can be programmed in the light menu.
4.1.5. OBJECT 2 EXTERNAL MOVEMENT – LIGHT – SWITCH
Input 1 Bit
Additional (secondary) detectors can be connected through Object 2 “external movement – light – switching”.
The received signal from external presence detectors is processed the same as if from its own detector and works in parallel.
Object 2 is used to set up a Master-Secondary detector configuration as follows:
Secondary devices: Connect all outputs of the secondary devices ( object 0 ) to the input external movement-light-switching (object 2 ) of the master device.
4.1.6. OBJECT 3 INPUT – LIGHT – FORCED CONTROL / LOCK
Input 2 Bit
The meaning of this object is defined by the Light forced control object or disabling object parameter.
Forced control object:
Object 3 when used as a forced control object has 3 values that can be received by a 2-bit command:
1. Forced control object ON (control = 1, value = 1)
An ON command is sent unconditionally to the output – light (object 0).
The follow-up timer is disabled and the timer release time starts.
If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.
2. Forced control object OFF (control = 1, value = 0)
An OFF command is sent unconditionally to the output – light (object 0).
The delay timer is disabled and the timer release time starts.
If after having terminated the release time and no further command is sent to the forced control object, normal operation is resumed.
3. Forced control object auto (control = 0, value = 0)
Normal operation is resumed immediately.
Locked object:
Object 3 when used as a locked object has 2 values which can be received by a 1-bit command 0 and 1:
The response to a switch command on this object is controlled by two more parameters:
Light if locked object = 0, and Light if locked object = 1,
Both parameters can specify one of the following commands:

• forced control ON
• forced control OFF
• automatic
• lock (actual state)
• do nothing

Note: Incorrect settings of parameters such as: locked object, lock at 0 and no action at 1 and release time restraint OFF can completely inactivate the correct function of the presence detector.
4.2. HVAC channel
Output 1 bit
The HVAC channel has the same objects and the same operating modes as the light channel. It works the same way as the light channel as well.
The motion detection function, however, has been expanded and substituted by a “longer presence detection”. This is done by setting several equally long monitoring time windows. At least one motion
detection must occur during each time slot.
The parameters are:

• number of monitoring time windows
• length of the monitoring time window (s)

Presence function
The HVAC output can be used as presence detection. To activate this, the number of observation time windows must be set to 1 and the length of the observation time window set to 1 second. The presence the signal is independent of the ambient light level.
4.2.1. OBJECT 4 OUTPUT – HVAC – SWITCH
Output 1 bit
Object 4 “Output – HVAC – Switch” is similar to object 0 “Output – light – switch” but has additional functions (see HVAC parameters, page 10).
4.2.2. OBJECT 5 EXTERNAL SWITCHING / STATUS – HVAC
Input 1 Bit
Object 5 “External switching / status – HVAC” is identical to object 1 “External switching / status – light”.
4.2.3. OBJECT 6 EXTERNAL MOVEMENT – HVAC
Input 1 Bit
Object 6 “External movement – HVAC – switch” is identical to object 2 “External movement – light – switch”.
4.2.4. OBJECT 7 INPUT – HVAC – FORCED CONTROL
Input 2 Bit
Object 7 “Input – HVAC – forced control” is identical to object 3 “Input – light – forced control”.
4.2.5. OBJECT 7 INPUT – HVAC – DISABLE
Input 1 Bit
Object 7 “Input – HVAC – disable” is identical to object 3 “Input – light – disable”.
4.3. BRIGHTNESS THRESHOLD SWITCH

This block has two output objects: Threshold switch and brightness value
4.3.1. OBJECT 8 THRESHOLD SWITCH BRIGHTNESS – SWITCHING
Output 1 bit
Output object 8 sends an “ON” if the measured brightness is greater than the Value for switching the threshold value switch parameter. If the measured brightness drops below the Switch-on threshold value – (minus) the
Hysteresis parameter, an “OFF” is transmitted.
4.3.2. OBJECT 9 BRIGHTNESS VALUE
Output 2 bytes
Output object 9 sends the current measured brightness value in lux. The transmission is triggered by changes that are greater than the parameter Transmission of the light value in case of a change of or cyclically with the
time stipulated for Cyclical transmission of the light value.
If the cycle time is set to “OFF” there will be no cyclical transmission.
4.4. AD calibration value
Output 2 bytes
Object 10 is not transmitted autonomously. It can only be read. Its unsigned 16-bit value represents the momentary value of the AD converter for the brightness measurement.
The brightness measurement can be calibrated as follows:

• Measure the incident light – on a desktop for example – with an external lux meter. This represents the reference lux value.

• Read out the AD calibration value (communication object 10) in the ETS.
  Note: In the menu Read/send value, use type 7.001 unsigned 2 byte counter! The AD value read then appears in the Value received menu as 739 pulses, for example.

• With full access, enter the two values Lux value and AD calibration value as parameters.

4.5. OBJECTS FOR CONSTANT LIGHT CONTROL
4.5.1. OBJECT 16 CONSTANT LIGHT – SWITCH ON/OFF
Input 1 bit
This input allows the constant light controller to be switched ON and OFF (Object).
Alternatively, the constant light controller can be activated by motion detection on the light or the HVAC channel.
4.5.2. OBJECT 17 CONSTANT LIGHT – RELATIVE DIMMING
Input 4 bit
Using this object, the current value is changed with relative dimming steps of 1%. Using a KNX push-button, the light can be dimmed and set to a new brightness level.
The new light value can then be displayed in Lux on a KNX touch panel through object 9: brightness value.
Important: In the menu, constant light takes over the setpoint after you can define the period during which the controller will remain switched off. After this interval, the new value is written to the RAM (not to the flash memory)!
Note: This new target value remains stored in RAM as long as there are people present in the scanned area. After switching the light channel off and back on again, the setpoint stored in ETS is adopted once again. If the newly changed set point are definitely taken over, set the parameter Keep changed set point to YES (see also section 3.8 Constant light parameter page 18)
4.5.3. OBJECT 18 CONSTANT LIGHT – PRESET DIMMING
Input 1 Byte
With this object the user can define a new dim set point in % over the bus.
4.5.4. OBJECT 20 CONSTANT LIGHT – FORCE CONTROL
Input 1 bit
In accordance to the parameters force output at ON and force output at OFF, various options can be selected: no reaction, minimum brightness, maximum brightness
4.5.5. OBJECT 21 CONSTANT LIGHT – SCENE
Input 1 byte
Scene selection input. 8 adjustable scenes can be selected via ETS.
This object has no switch function but only changes the brightness setpoint values.
4.5.6. OBJECT 22 CONSTANT LIGHT – OUTPUT CHANNEL 1
Output 1 byte
This is the constant light control signal (% brightness) for the dimming actuator of lighting 1
4.5.7. OBJECT 23 CONSTANT LIGHT – OUTPUT CHANNEL 2
OUTPUT 1 byte
This is the constant light control signal for the dimming actuator of lighting 2.
The lux value is equal to channel 1 +/- offset.

PROGRAMMVERSION 2.7

With the program version 2.7, the functional possibilities of the presence detector – series Swiss Guard 360P KNX / KLR RA / EA expanded and existing features of program version 2.4, have been supplemented respectively adapted.
The standard values (default values) of the parameters compared to the settings in version 2.4 are partially modified.
These settings allow a simple and safe functionally check (initial start-up ) of the presence detector.
Older devices of software version 2.4 can also be programmed with the program version 2.7 ( backward compatibility ) .
However, supplemented functions and the additional communication objects are not all supported.

5.2.1. COMMUNICATION OBJECTS with Secondary Detector- Mode

Object forced control:
Object 3 as a forced control object knows 2 values (1-bit command ) that can be received :
If object forced control = 1: output ( Obj.0 ) remains locked when motion is detected, no telegrams are sent
If object forced control = 0: output ( Obj.0 ) AUTO ( normal operation )
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 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.

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 send 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 the parameterized value „Brightness below which sensor is active“, the light- off threshold is 10% increased above the actual brightness-value (obj9) plus 200LUX.

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.
5.3.3. Delay-time, mode semi- automatic
If the brightness is increasing during the delay-time and passes over the threshold “Brightness switch off level”, the light-channel (obj0/obj22) is switching off but the delay-time is continuing either. If the brightness reduces below the value “Brightness below sensor is active”, the light channel is switching ”ON” again, till the delay-time is expired.
5.3.4. Standby-functionality
When the light-channel is used as “dim completely”, a standby-light can be activated optionally.
Two pairs of values are available and can select with obj24.
The delay-time for the Standby-functionality can also parameterize as “Unlimited “ too. Emergency light with permanent minimum brightness.
If the brightness during standby increases over “Brightness switches off level”, the light-channel (obj0) is switching off.
If the brightness reduces below the value “Brightness below sensor is active”, the light channel is switching ”ON” with the standby settings again till the delay-time (standby) is expired.
