The devices are designed for mounting on
ceilings. They contain highly sensitive
sensor/lens systems and have, depending on
the application selected, various functions. The
overall function of the devices also depends on
the installation height.
The Busch-Watchdog® Präsenz tech is
intended solely for indoor use, e.g. in offices,
schools or private buildings. The devices, for
example, serve for switching and regulating
lighting and/or HKL (HVAC) systems in
dependence of brightness and/or movement.
Please note that the Presence detector is not
suitable for use as an intrusion or attack alarm
since it lacks the required safety against
sabotage in accordance to the German VdS
(Authority on Safety and Security).

Functions
The devices described here are presence detectors. The difference between movement detectors and presence detectors is
the resolution of the segments. The detection segments of a presence detector are smaller due to the higher resolution and
therefore also respond to the slightest movement of a person. In addition, with the function types of constant light switch and
constant light controller these presence detectors continuously measure the brightness.
The Busch Präsenz tech is available in two versions:
®
The Busch-Watchdog Präsenz tech KNX (6131/10-500) offers movement detection with 2 channels and constant light
switching. Constant light switching adds light when persons move within the detection range and the daylight does not meet
the required brightness level in the room. The Busch Präsenz tech detects the luminosity of the lamp used. As soon as the
natural light is adequate, the connected light sources are deactivated.
The combination of these two functions results in two advantages:
•
Energy is being saved since the lamps are deactivated as soon as the natural light has reached sufficient brightness.
•
Additional energy is saved since the lights are only switched on when persons are inside the room.
®
The Busch-Watchdog Präsenz tech DualLINE KNX (6131/11-500) can both switch lamps and also dim them. This makes
constant light control much more precise and maintain the brightness level in the room at the desired level.
The integrated HVAC function makes it possible to control heating, ventilation and air-conditioning in the respective
detection range when someone is present. This additionally saves energy. Two channels are available for this function.
®
Special comfort is made possible with the integration of the IR manual transmitter (6010/25-500). The Busch-Watchdog
Präsenz tech DualLINE KNX receives the signals and converts them on the bus.
®
The Busch-Watchdog Präsenz tech DualLINE KNX additionally has numerous general functions, which are listed in the
table on page 7. There you will also find a reference to additional explanations.
Both devices can be easily updated to the latest software version with the programming adapter. The various operating
modes of the devices can automatically regulate the presence detector, or only when it has been activated via a control
element for example.
Constant light
Depending on the version of the equipment, the Busch-Watchdog ® Präsenz tech offers a variety of options to maintain the
brightness in the room at a pleasant level. There is a difference between the functions of the constant light switch and the
constant light controller. Both functions ensure that the brightness does not drop below a certain level when persons are in
the room. The use of a presence detector is especially practical for work stations in an office, since even small movements
are detected.
The constant light switch can switch lamps on and off. The constant light controller can additionally dim lights, to maintain a
level that is as constant as possible. Both functions work in dependence of light conditions and movement in the detection
range. The devices can operate either in "automatic" or "automatic time control" mode. If automatic time control is selected,
for example, the light can be switched on manually via a touch sensor. The light remains on as long as movement is
detected and daylight is not sufficient. If no movement is detected, the light-on time expires before an OFF telegram is sent
via the output on the bus. In automatic mode the movement sensor also takes over the switch-on function as soon as
someone enters the room.
4 | 0073-1-7613 | KNX Technical Reference Manual
Constant light switch
The constant light switch switches on lamps in the room as soon as movement by a person is detected and the desired
brightness value is not attained by the entering daylight alone.
The programmed set value is maintained as long as people are in the detection range. The application detects when the
entering daylight is sufficient. The lamps are then switched off again to save energy.
Control parameters:
1 Set value (lx)
2 Delay time after switch-on up to measurement of the artificial light component
3 Minimum time above the switch-off threshold (min)
To set up the constant light-switch function the ETS plug-in Power-Tool is required. Here are several parameters are found
again with certain dependencies. These dependencies are displayed with the diagram.
A light-on time can be set. This time expires when the presence detector no longer senses movement. After expiry, an OFF
telegram is sent on the output. Connected lamps are switched off. The light-on time should always be higher than the "delay
after switch-on up to measurement of the artificial light component" (2). In the worst case the light sensor would measure the
artificial light component when the lamps are switched off.
This should be avoided since the entire constant light switching function is based on this value.
The "delay after switch-on up to measurement of the artificial light component" (2) is to be used especially with lamps that
take a few seconds to reach their full brightness. Fluorescent lamps require up to 250 seconds, whereas incandescent lamps
reach their full brightness almost immediately.
The "minimum time above the switch-off threshold" (3) ensures that the natural light component attains a stable value before
the artificial light is switched off. If this time is too short, this could lead to an unwanted activation and deactivation of the
lamps in the room.

6 | 0073-1-7613 | KNX Technical Reference Manual
Constant light controller
Both the constant light controller and the constant light switch ensure that the level of brightness in the room does not drop
below the desired level. However, the brightness controller is additionally able to send telegrams for dimming lamps to the
KNX bus. This enables a constant level to be attained due to the dimming of lights brighter and darker - always in
dependence of the natural light. And the accuracy of the control increases with the operating time. The constant light
controller remembers the luminosity of the lamps used. That is why the lamps used later must also be used during
commissioning of the presence detector with the constant light control function.
Next to the brightness the constant light controller also responds to the presence of persons in the room.
1 Natural light | 2 Brightness in the room | 3 Programmed brightness threshold | 4 Artificial light
Note:
If output 2 is activated, constant light control continues on the set / stored value. Output 1 is the leading output. Due to the
dependence and the factor between output 1 and 2, the lamps can have different brightnesses / switching states; for
example, the lamps in the rear section of the room (output 1) are brighter than the lamps installed closer to the window
(output ).

Detection range
The detection range of the KNX presence detector depends on the movement of persons and the mounting height in the
room. The movement sensor detects the smallest of movements, e.g. at PC work stations, at desks, etc. Here it must be
distinguished between the inner and outer detection range and the mounting height of the presence detector.
Inner detection range (seated persons)
Seated persons must be completely within the detection
range. The shorter the distance between the person to be
detected and the presence detector, the smaller the
movement can be that is still detected. The reference level
for the detection of seated activities is approx. 1 m. At this
height, the detection range is 6 m in diameter (mounting
height of the presence detector = 2.5 m). At a higher
mounting height, the detection range becomes larger, but
the detection density smaller.
Outer detection range (walking persons)
For the detection of walking persons, a larger detection
range is available. The reference level for detection is the
floor. A mounting height of 2.5 m results in a diameter of
approx. 8 m for the detection range.
Limited detection
The detection range of the presence detector can be
restricted. The device does not need to be covered
mechanically for this. Individual sectors can be deactivated
in the application.

Sources of interference
Switching is triggered by movement. If a foreign heat source is in close proximity, this can cause false triggering. Here a
distinction must be made between foreign heat sources and limited visibility as a source of interference.
®
Limited visibility of the Busch-Watchdog Präsenz tech
The detection range of the Busch-Watchdog® can be
obstructed by various objects, e.g.:
Lamp rows that are mounted lower than the presence
detector
Large plants
Partitions
Glass panes
Foreign heat sources
Rapid changes in temperature surrounding the presence
detector can also trigger unwanted switching, e.g.:
Additional fan
Switching on/off of lamps in the direct vicinity (< 1.5 m)
of the presence detector, in particular incandescent
lamps and halogen lamps
Moving machines, suspended posters etc.
Heat sources without interference effect
If the temperature changes only slowly, this will not affect
the switching behaviour of the presence detector, e.g.:
Radiators (distance > 1.5 m)
Surfaces heated by the sun
EDP systems (computers, printers, monitors)
Ventilation systems, when warm air does not flow
directly into the detection range of the presence
detector

Remote control
The DualLINE presence detector has a sensor for receiving infrared signals. This allows the IR manual transmitter 6110/25500 to be used, for example. Two channels that can be selected on the transmitter are available for operation. The blue and
the white channel.
The following example is to serve as an aid for commissioning.
The infrared functions can be programmed in the presence detector. For button M1 (blue and / or white) the function
"Switching, rocker switch left / right" is selected. The parameter "Reaction to rising edge" is shown within this function. This
parameter is to be set on "ON". The function has the communication object "Switching".
This object must now be connected with the object "Save set value" of the constant light application. This stores the current
light value as set value as soon as button M1 is pressed.
The light can, for example, be set with the manual transmitter. For this, one or several button pairs are occupied with the
function "Dimming rocker switch total" and connected directly with the dimming actuator.
Now use the button pair selected to set the desired brightness and save the value with button M1.

Commissioning
To commission the presence detector with a constant light function you have various parameters available in Power-Tool.
These parameters allow numerous options for setting, in order to adapt the working mode of the device to individual
requirements and circumstances.
Therefore, the type of furniture, floor coverings or sources of interference in the room is of significance. The value to be set
in a room with dark furniture will be less than in a room with a light-coloured floor and light-coloured furniture. Also the effect
of the size of the interference, such as heat sources or short-term changes in brightness, such as passing clouds, can be
taken into consideration.
Set value
Please note that the lux value to be set in the parameters does not correspond to the value required at the height of the
desk. The light sensor is installed on the ceiling and can only measure the luminosity that is reflected from the opposite
surfaces. The set value to be entered is therefore lower than the light value at the height of the work station.
Dim the lights to the desired intensity. Then save the measured light value via the memory object of the presence detector.
The stored value can also be read via the object for the set value.
Outputs
The presence detector can also regulate two independent light circuits per channel via the two outputs.
The value of output 2 results from the value of output 1 and the respective proportionality factor. If the required set value is
not reached, control continues beyond the factor.
Example:
An office is fitted with two light rows. Output 1 controls the light row in the darker part of the room.
Light row 2 in the front window area is connected to output 2. For the maximum brightness during the day a proportional
factor of 70% is sufficient for output 2. During the night the full brightness in the room is not sufficient from output 1 and
output 2. Output 2 would now control beyond the proportional factor until the set value or the full brightness of the lamp has
been reached.
Light-on time
The presence detector will switch off or dim the lamps in the room if no movement is detected. A light-on time can be set to
prevent the lamp from being switched off immediately. This time expires as soon as movement is no longer detected. It will
always start again from the beginning.
Hysteresis
The hysteresis is a percentage value (+/-) that is related to the set value in lux. The hysteresis is a tolerance for maintaining
the set value. The preset value is sufficient for most applications.

Proportionality factor
An office has two light rows. Light row 1 in the rear area of the office is connected to output 1. The light row in the window
area is connected to output 2. For the maximum brightness during the day a proportionality factor of 70% is sufficient for
output 2. This means that the value at output 2 corresponds to the value of output 1.
During the night this brightness in the room is not sufficient. Output 2 would now control beyond the proportionality factor
until the set value or the full brightness of the lamp has been reached. The proportionality factor can also be set up for
output 2 and always relates to output 1. The factor can only receive a maximum value of 100%. That is why it should be
ensured that output 2 regulates the lamp in the brighter part of a room.

Description of application
10.1
Movement detector
The movement detector application can trigger telegrams on the bus when a movement is detected in the detection zone.
Telegrams can also be sent on the bus when telegrams are received on the 1-bit communication object "External pushbutton
input". This means that a unit can be activated by additional KNX devices as if a movement was detected. The time for
sending out a telegram depends especially on the operating mode that has been set. The movement detector can operate in
the following modes: "Signaling", "Automatic time control", "Semi-automatic" or "Automatic".
In the "Signaling" mode the movement detector is in the position to send telegrams cyclically on the "Start movement" 1-bit
communication object.
In the "Automatic time control" mode the movement detector must be activated manually via the receipt of an ON telegram
on the "External pushbutton input" object. The device switches off after the specified light-on time beginning from the most
recent detection or manually.
In the "Semi-automatic" mode the movement detector switches on automatically when detecting a movement. It switches off
at the receipt of an OFF telegram on the "External pushbutton input" object.
The movement detector switches off automatically after 6 hours.
In the "Automatic" mode the movement detector switches on automatically when detecting a movement. It switches off after
the specified light-on time beginning from the most recent detection or through the receipt of an OFF telegram on the
"External pushbutton input" object. When switching off manually the detection of movement is suppressed for the
parameterised pause time via the internal sensor.
The movement detector can be activated permanently via the "Switchover of external pushbutton input" 1-bit communication
object. The function can, for example, be used during cleaning actions to cause all the movement detectors to activate
themselves even when no movement was detected.
If a movement detector works in an operating mode with light-on time, this can be adjusted during operation via a separate
communication object. This would allow different light-on times to be used for mornings and for evenings.
The behaviour can be adjusted so that no undefined state arises after a bus voltage failure and subsequent return of bus
voltage.
The movement detector can be blocked via an enable object.
The movement detector can switch brightness-dependent or brightness-independent. The setting parameters can be used to
adjust the threshold value of the light sensor. The brightness threshold can also be adjusted via communication objects via
the bus.

Staircase lighting
With the "Staircase lighting" application, switching telegrams or value telegrams can be provided with a light-on time.
Depending on the parameterisation, the application shows different communication objects:
- a 1-bit object for input and output
If an ON telegram is received via the "Input/Output" object, the light-on time is started immediately. This can be a light-on
time of 00:10 min to 88:45 min, which is adjustable in 0.1 s steps. After expiration of the light-on time, the "Input/Output"
object sends an OFF telegram.
- two 1-bit objects for input and output
- and two 1-byte objects for input and output
If a telegram is received via the "Input" object, the light-on time is started immediately and a telegram with the same value of
the telegram received on the input is sent out on the "Output" object. This can be a light-on time of 00:10 min to 88:45 min,
which is adjustable in 0.1 s steps. After expiration of the light-on time, the "Output" object sends out an OFF telegram (1-bit)
or a telegram with the value "0" (1-byte).
Via two additional communication objects, it is possible to specify the light-on time and the switch-off prewarning time. The
2-byte values received are written to the memory of the device and are retained even after a bus power failure and
subsequent return of voltage.

Gate
The "Gate" application allows specific signals to be filtered and the signal flow to be temporarily blocked. The function has
three communication objects: "Control input", "Input" and "Output".
The input or output object can assume different sizes.
The bit size can be freely assigned with the "Not assigned" setting. This means that the first internal or external group
address/action that is assigned and already connected to some other communication object will specify the size.
The control can occur from "Input to output" or also from "Output to input", provided the control input allows this. Enabling
via the control input can occur via an ON or an OFF telegram.
If, for example, the "Control input" setting is set to "ON telegram", only telegrams from the input are transmitted to the
output, if prior to this the control input has received an ON telegram.
It is also possible to block signals via the "Filter function" setting. Either "nothing is filtered out" or the signal "ON is filtered
out" or the signal "OFF is filtered out". This function is always necessary, for example, when only the ON telegram is
interesting for a sensor and the sensor does not offer any filter function in its application program.

Min/Max value transducer
Up to eight input values can be compared with each other using the "Min/max value transducer" application. The application
can output the highest input value, the smallest input value or the average of all input values on the output.
The size of the input objects, and with it also the size of the output object can be adapted for the most diverse applications.
You can select from the following object types:
– 1-byte 0..100 %, for comparison of percent values
– 1-byte 0..255, for the comparison of decimal values between 0 and 255
– 2-byte float, for the comparison of 2-byte floating point values (physical values such as temperature, brightness value
etc.)
– 2-byte signed, for the comparison of decimal values between -32,768 and +32,767
– 2-byte unsigned, for the comparison of decimal values between 0 and 65,535
– 4-byte float, for the comparison of 4-byte floating point values (physical values such as acceleration, electrical current,
work etc.)
– 4-byte signed, for the comparison of decimal values between -2,147,483,648 and 2,147,483,647
– 4-byte unsigned, for the comparison of decimal values between 0 and 4,294,967,295
Hint:
With whole numbers the average value is rounded.

Threshold value / hysteresis
With the "Threshold value / Hysteresis" application, value telegrams can be received on an input communication object and
compared with threshold values specified in the device.
Predefined values are sent out on the communication "Output" communication object if the upper or lower thresholds are
exceeded. The size of the object can be adjusted for different applications.
The function can be temporarily blocked via an enable object.
If the value of the lower threshold lies above the value for the upper threshold, the function is not executed.

PWM inverter
With the "PWM inverter" application, a 1-byte input signal can be converted to a 1-bit signal or a 1-byte signal via an
equivalent pulse-width modulation. This function is required, for instance, if a room temperature controller issues a constant
control value that controls a switching heating actuator (for electrothermal actuating drives).
The function of the 1-byte sized activation is required if the room temperature controller can only send out constant control
values or a constant control value is required for other functions (such as central supply line temperature control).
There is the option of activating a force-position. The force-position is used for certain events such as the opening of a
window or for moving a heating actuator that is to be activated to a specific position for the dew point alarm.
If "Alert" is activated, the additional communication object "Fault" is available. A fault will then occur if the "Input" object has
received no further telegram within a certain period of time. Possible reasons for this could be, for example, that the
associated room temperature controller fails or that during a cross-line function the telegrams no longer pass the coupler. In
this case an ON telegram is sent out on the "Fault" communication object and the "Input" object assumes the "Value for
fault".
An additional "Enable" object provides the option of temporarily blocking the function.

Priority
The "Priority" application has 3 communication objects, a 1-bit object "Switch input", a 2-bit object "Input priority" and a 1-bit
object "Output". The telegrams received on the "Switch input" are transferred to the "Output" depending on the state of the
"Input priority" object.
The 2-bit object "Input priority" can receive and differentiate between four different values (0, 1, 2 and 3). Here, the "Output"
object is positively driven. Three different states are differentiated:
- "Input priority" has value "3": the value that is present on "Switch input" has no meaning. The "Output" is switched to
positively driven and has the value "1".
– "Input priority" has the value "2". The value that is present on "Switch input" has no meaning. The "Output" is switched off
positively driven and has the value "0".
– "Input priority" has the value "1" or "0". The "Output" is not positively driven. The "Switch input" is linked to the status bit of
the priority object OR and transferred to the "Output".
During a positive drive, changes of the "Switch input" object are saved, even if the current state on the "Output" object does
not immediately change through this. If the positive drive is terminated, a telegram transmission on the "Output" occurs
according to the current value of the "Switch input" object.
