2.4 Functions
The functions of the motion detector are divided into the area’s “General settings”, “Light channel 1
and 2”, “HVAC channel”, “Detection channel (Alarm)”, “Logic”, “LED”, “Scenes”, and “Brightness”. For
the SCN-BWM55/63T.x2, the areas “Temperature”and “Buttons”are also available:
General Settings
The general settings are used for the basic configuration of the unit. Basic settings for sensitivity and
basic settings for brightness can be made here as well as the fallback times can be configured.
Furthermore, a cyclically transmitted "Operation" telegram can be activated.
Light channel 1 and 2
Light channel 1 and 2 can be configured and activated/deactivated separately from each other. The
active sensors can be configured for each light channel. The operating modes fully automatic and
semi-automatic (manual switch-on) are available. Furthermore, different values can be sent for
Day/Night (depending on the Day/Night object). A switching object, a scene object, or an absolute
value (dimming absolute) can be sent as an output object. Each light channel can be switched with
priority via a forced guidance object or a block object.
HVAC channel
The heating, ventilation and air-conditioning channel is the interface between the motion detector
and other systems. In contrast to the light channels, the HVAC channel has adjustable observation
windows with which the presence in the room can be monitored. By using this channel, it is possible,
for example, to control the ventilation of a room according to demand or to switch other HVAC
functions on presence/absence.
Detection channel (Alarm)
This channel is used to detect movements during absence. For this purpose, the channel has a
separate sensitivity setting and its own enable/disable object with which monitoring can be started.
In this menu you can also activate the motion direction detection.
Logic
Up to 4 different logics can be activated. These can be set with the functions AND, OR, XOR. Each
logic block can be activated with up to two internal logic objects and up to four external logic objects.
Switching commands, scenes, values or 2-bit priority control objects can be sent as output objects.
LED
A white, a green and a red LED are available for display.
The green LED can be used to signal motions, or the LED can be switched depending on an external
object.
The white LED can be configured as a night light or as a motion indicator. Furthermore, the LED can
be switched via a separate object. The brightness of the LED can be set from 1 - 100%.
The red LED can optionally be used as a pure programming LED or switched via a separate object.
Scenes
Up to 8 scenes can be activated which can cause adjustable actions in the light channels 1/2.

Brightness
The correction of the measured brightness value and the sending conditions for the light value can
be set here.
Buttons (only SCN-BWM55/63T.x2)
Two buttons are available on the unit. Using these buttons, functions such as switching, dimming,
blinds or sending a value can be carried out - both individually and in groups - as well as internal
functions that relate to switching to manual mode or lock/forced operation.
Temperature (only SCN- BWM55/63T.x2)
By activating the sensor, the measured temperature can be sent to the bus. In addition, the
transmission behaviour of the measured value as well as a correction value can be configured.
Long Frame Support
Device supports the sending of longer telegrams and thus the storage of more user data per telegram.
This significantly shortens the programming time (from ETS5).
Requirements: Use of a programming interface which supports the transmission of long frames, e.g.,
MDT SCN-USBR.02 or SCN-IP000.03 / SCN-IP100.03.
Updateable via DCA (from Hardware Version R2.0)
If necessary, the actuators can be updated with the help of the MDT Update Tool.
2.5 Commissioning
After wiring, the allocation of the physical address and the parameterization of every channel follows:
(1) Connect the interface with the bus, e.g., MDT USB interface.
(2) Switch on the bus voltage.
(3) Press the programming button on the side of the unit (red programming LED lights up).
(4) Loading of the physical address out of the ETS-Software by using the interface (red LED goes
out, as well this process was completed successful).
(5) Loading of the application, with requested configuration.
(6) When the unit is ready for operation, the desired function can be tested (is also possible with
the help of the ETS software).

Value for Day/Night determines whether the detector is in Day or Night mode. The parameters set
for Day/Night then apply accordingly.
Sensitivity
The sensitivity of the sensors is set here. 1 means very low, the higher the value, the more sensitive
the sensors become. This setting has an influence on the detection range. If the value is set low,
movement is only detected relatively close to the detector. If the value is set to e.g. 8, a movement is
already detected at a greater distance from the detector.
Note: From database V4.4 onwards and from device HW R2.5 onwards, it is also possible to set the
sensitivity to level 0 (lowest level).
Brightness
This allows a specific operating range to be specified for the Presence Detector. The parameters
"Switch-on threshold “Day/Night”" defines the brightness threshold below which the detector
detects presence. Above this threshold, no more movement is detected, but the detector does not
switch off the light as soon as the brightness is exceeded; instead, the follow-up time runs normally.
The set threshold value can be changed via object "98 - Set switch-on threshold for light channels".
The value always applies to the current operation. If the detector is in Day mode, the threshold for
"Day" is changed. If the detector is in Night mode, the threshold for "Night" is changed.
The "Switch off if exceedance" parameter causes the light channel to switch off immediately when
the set value is reached. The value should not be set too low, however, as this could result in the
light channel switching on/off continuously.
Example: If the detector switches ON and the brightness in the room with the light switched on is
brighter than the "Switch off if exceeded" value, the channel switches off again immediately.
Fallback forced guidance/lock: If the detector is in a certain state via forced guidance or locking, it
can be defined whether it should fall back into automatic mode after a fixed time.
With the setting "after presence and follow-up time", the presence in the room continues to be
detected during forced guidance/lock. If there is now no one in the room and the follow-up time of
the channel has elapsed, the set "Manual mode follow-up time..." starts from this point, after which
the detector switches back to automatic mode.
Fallback for external push-button long (manual => auto): If the detector is switched to manual mode
via "External push-button long", a fallback to automatic mode "with fixed time" or "after presence
and follow-up time" can also be achieved here. The procedure corresponds to the description in the
previous point "Fallback forced guidance/lock".

Active sensors
The active sensors can be set for each light channel. This allows the detection range of the channel to
be limited. For example, if only one area in a corridor is to be detected, only one sensor can be
activated. The alignment of the sensors becomes recognisable by activating the parameter
"Information about sensor assignment".
Sensitivity
If a channel is set to “basic setting (General settings)”, the sensitivity always refers to the settings,
made in the “General settings” menu. If set to “individual”, the parameters for trigger sensitivity and
presence sensitivity appear and can be made individually for the corresponding light channel.
Note: From database V4.4 onwards and from device HW R2.5 onwards, it is also possible to set the
sensitivity to level 0 (lowest level).
Brightness
With "Basic setting or object "Dark switch" active", brightness refers to the settings in "General
setting". However, this can become brightness-independent via the "Dark switch" object with a 1 and
thus switches at any brightness.
No threshold applies via the "independent of brightness" setting and the channel always switches.
Fully automatic
If the presence detector is set as fully automatic, every detected presence causes the output to
switch on and is switched off again after the follow-up time has elapsed.
Half automatic (manual switching)
In half-automatic mode, the output is switched on via the object "External push-button short" and
automatically switched off again after the follow-up time has elapsed.
The follow-up time describes the time that elapses after the last detection of a movement until the
output is switched off. The follow-up time can be set differently for Day/Night. For example, with a
follow-up time of 3 minutes, the light would be switched on for at least 3 minutes if movement was
detected. Each new detection leads to a retriggering and thus a restart of the follow-up time.
In addition, a "reduction of the follow-up time" can be activated. In this case, two additional
parameters are displayed:
Maximum duration for short-time presence: Indicates the duration between the first and the last
movement detection to activate the short-time presence.
Follow-up time for short-time presence: Indicates the duration of the follow-up time when the
short-time presence was activated.
If the first and last movement was detected within the set duration for short-time presence when
short- time presence was activated, the output is not switched on for the regular follow-up time, but
only for the follow-up time of the short-time presence.

Active sensors
The active sensors can be set for each channel. This allows the detection range of the channel to be
limited. For example, if only one area in a corridor is to be detected, only one sensor can be activated.
The alignment of the sensors can be recognised by activating the parameter "Information about

Fully automatic
If the presence detector is set as fully automatic, every detected presence causes the output to

Half automatic (manual switching)
In half-automatic mode, the output is switched on via the object "External push-button short" and
automatically switched off again after the follow-up time has elapsed.
Monitoring time slot
The monitoring time slot is available for the HVAC. This causes a longer detection to be required for
switching on. To switch on the channel, at least one detection must have taken place in each of the
set monitoring time slots.
The length of the monitoring time slot determines how long the system waits for a detection within a
time slot.
The follow-up time describes the time that elapses after the last detection of a movement until the
output is switched off. The follow-up time can be set differently for Day/Night. For example, with a
follow-up time of 3 minutes, the light would be switched on for at least 3 minutes if movement was
detected. Each new detection leads to a retriggering and thus a restart of the follow-up time.

Table 8: Settings –Forced guidance/Lock object
The presence detector can be overridden with the forced guidance/lock object and call up a certain
status.
The forced guidance object knows 3 possible states:
•Force control ON (control = 1, value = 1)
The command for “ON” is sent unconditionally to the output object. The evaluation is then
stopped and the release time for force control begins. If nothing is received on the force
control object after the release time has expired, normal operation is resumed.
•Force control OFF (control = 1, value = 0)
The command for "OFF" is sent unconditionally to the output object. The evaluation is then
stopped and the release time for force control begins. If nothing is received on the force
control object after the release time has expired, normal operation is resumed.
•Force control AUTO (control = 0, value = 0)
After that the normal operation of the detector is continued
