2 Overview

2.1 Overview devices

The manual refers to the following devices: (Order code printed in bold type):

 SCN-BWM55.01 Motion detector, 2 Pyro detectors, matt finish

o 2 Pyro-detectors, Sensitivity separately adjustable for day/night/presence

2 separate configurable Light channels, HCV and Alarm channel;
4 Logic functions (And-/Or-/XOR-function) configurable;
green, white, red LED freely configurable;
8 scenes activatable and adjustable;
Motion direction detection

 SCN-BWM55.G1 Motion detector, 2 Pyro detectors, glossy finish

o Functions as above

2.2 Usage & possible applications

The MDT motion detector switches depending on the ambient brightness and presence. It can be
used for demand-driven switching in order to switch economically and only when required. The
motion detector can thus help to reduce unnecessary switching times to a minimum, especially in
commercial premises, but also in rooms that are seldom used, such as bathrooms and toilets or
rooms that are used as passageways such as hallways.
An additional channel transmits the presence information in the room to other trades such as
heating, ventilation, air-conditioning or blind control systems. This means that the motion detector
can also be used in other trades.
The MDT motion detector is designed for wall mounting and impresses with its flat design and 180°
detection range.

2.5 Functions

The motion detector functions are divided into the following areas: general settings, light channels 1
and 2, HCV, alarm, logic, LED, scenes and brightness:

 General Settings

The general settings are used for the basic configuration of the motion detector. Basic
settings for sensitivity and basic settings for brightness can be made here as well as the
follow-up times. In addition, a cyclically sending "In operation" telegram can be activated.

 Light channel 1 and 2

Light channel 1 and 2 can be parameterised and activated/deactivated separately from each
other. The active sensors can be parameterised for each light channel. The operating modes
fully automatic and half-automatic (manual switching on) are available. Furthermore,
different values for day/night (depending on the day/night object) can be sent. A switching
object, a scene object or an absolute value (dimming absolute) can be sent as an output
object. Each light channel can be given priority by a force control object or a blocking object

 HCV

The heating, climate and ventilation channel is the interface of the motion detector to other
systems. In contrast to the light channels, the HCL channel has adjustable monitoring time
slots with which the presence in the room can be observed. By using this channel, it is
possible to control the ventilation of a room as required or to switch other HCV functions in
presence/absence, for example.

 Alarm

The alarm 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, green and red LED are available for display. The green LED can be used to signal
movements or the LED can be switched depending on an external object.
The white LED can be parameterised as night light or motion indicator. Furthermore, the LED
can be switched via a separate object. The brightness of the LED is adjustable from 1-100%.
The red LED can be used either as 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.

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) Switching the power supply
(3) Set bus power up
(4) Press the programming button at the device (red programming LED lights)
(5) Loading of the physical address out of the ETS-Software by using the interface (red LED goes

off as soon as this process was completed successfully)

(6) Loading of the application, with requested parameterization
(7) If the device is enabled you can test the requested functions (also possible by using the ETS-

Software)

Table 5: Basic settings - light channel

The parameters brightness and monitoring time slot are explained in more detail as follows:

 Brightness (only light channel 1/2)

Sensor activation/deactivation is only available for the light group. In this way, the presence
detector can be assigned a specific work area. The parameter "Sensor activation below" defines
the brightness threshold below which the detector detects presence. No movement is detected
above this threshold, but the detector does not switch off the light as soon as the brightness is
exceeded. This can be achieved with the parameter "Switch-off when exceeding". However, this
value should not be set too low, as this can result in a continuous on/off switching.

 Monitoring time slot (only HCV)

The monitoring time slot is only available for one HCV channel. This means that a longer
detection time is required for switching on. In order to switch on the channel, at least, one
detection must have taken place in each of the set monitoring time slots

4.2.2 Channel Mode Selection

A distinction can be made between two operating modes: Fully automatic and half-automatic:

 Fully automatic

If the motion detector is set as fully automatic, each detected presence causes the output to
be switched on and is switched off again after the follow-up time has expired.

Half automatic

In half automatic mode, the output is switched on via the "External push-button short"
object and is automatically switched off again after the follow-up time has expired..

4.2.3 Follow-up time

The following figure shows the available settings for the follow-up time:

Figure 5: Follow-up time

The delay time describes the time that expires after the last detection of a movement until the
output is switched off. For example, with a follow-up time of 3 minutes, the light would be switched
on for at least 3 minutes with motion detection. Each new detection leads to a retriggering and thus
to a restart of the follow-up time..
In addition, a "reduction of 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 last
motion detection to activate the short-time presence..
Follow-up time for short time presence: Indicates the duration of the follow-up time if the short­time presence has been activated.
If the first and last movement within the set duration for short-time presence was detected 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.

Table 6: Settings - Force control/lock object

The motion detector can be overridden with the force control/lock object and call up a certain status.
The force control object knows 3 possible states:

 Force control ON (control = 1, value = 1)

The oad 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

As an alternative to the force control object, 1 or 2 locking objects of size 1 bit can be displayed. 3
different states can be configured for the lock object universal:
 Switch ON

The light channel sends the output value ON and remains in the ON state until the locking
process is deactivated..

 Switch OFF

The light channel sends the output value OFF and remains in the OFF state until the locking
process is deactivated..

 Lock (current state)

The light channel is locked in its current state and remains locked until the locking process is
deactivated..

4.2.7 Process Diagram

Fully automatic without orientation light:

Figure 10: Process diagram - Fully automatic without orientation light

In the operating mode "Fully automatic", the motion detector switches on automatically when
movement is detected. The object "External push button short" can be used to override the
automatic mode of the motion detector and force the motion detector into manual mode. From this
mode, the detector automatically returns to auto mode according to the settings in the menu
"General settings" - "Release of push button input"
If the output of the light channel is switched on (automatic mode - ON or manual mode - ON) and the
light channel is switched off via the object "External push button short", then the light channel is
blocked for 10 seconds for motion detection in order to leave the room and prevent brief restart.

The fully automatic mode with orientation light extends the fully automatic mode of operation by the
orientation light status. The orientation light can be activated as soon as the parameter "Object type
for output - light" is set to absolute dimming.
The orientation light is switched on as soon as the follow-up time of the light channel has expired.
The output is then switched to the orientation light state and can thus dim the light to a darker level
in order to be able to leave the room safely.

follow-up time has expired (= no motion detection for the set follow-up time).
The object "External push button short" can additionally override the light channel. The motion
detector can be switched to manual mode by pressing twice.

4.2.8 Master/Slave Operation

4.2.8.1 Light channel

In larger rooms often more than one motion detector is required. For detecting presence all over
the room, motion detectors have to be allocated in the whole room. But also in this case a detected
presence shall cause always the same settings independent of the place of detection. In this case one
detector operates as Master and an arbitrary number of motion detectors work as Slave.
The settings for the Master/Slave mode a e ade i the sueu light groups.

The Slaves must be configured as follows:

 Adjustment to fully automatic (every movement shall be sent)
 Set follow-up time to the same value as the Master
 Set object type for output - light to Swithig
 Activate cyclic sending for the output object

o Parameter: Output object 1 sends cyclic at ON
o Guide value: 1min; for longer follow-up times, e. g. at 15min the cyclic sending can

be increased to e. g. 5 min in order to reduce the bus load.

 Set Brightness parameter to brightness independent

The Master is parameterized as fully or half-automatic as desired.
A value of 10 minutes is recommended as the common follow-up time..

The objects have to be connected as follows:

 All output objects of the Slaves (Object 0) have to be connected with the object external

motion - Slave (Object 5) of the Master.

The master now evaluates every self-detected movement as well as movement detected by the
slaves. The master then switches the light groups according to its own settings, regardless of who has
detected the motion..

4.2.8.2 HCV

The Master/Slave control can also be applied to the HCV channel. The settings for the slave are the
same as for the slaves for the lighting groups. However, the settings for the brightness values do not
apply to the HCV channel. The observation windows must be set according to individual
requirements.
The objects have to be connected as follows:

 All output objects of the slaves (Object 40) have to be connected to the object External

motion (Object 45) of the master.

Table 14: Settings - Alarm function

The alarm function can be used to monitor a room in case of absence and to call certain actions in
the KNX system during motion detection.

The individual parameters are described in more detail below:

Release sensitivity for Day/Night

The release sensitivity describes the sensitivity in stand-by mode (the output is switched off, no
motion has been detected)

Presence sensitivity

Presence sensitivity describes the sensitivity in presence mode (the output is switched on, a motion
has been detected.).

Motion filter in Standby

In order to avoid false detection, a motion filter can be activated which filters out very short motions
e. g. by draughts.

Follow-up time

The follow-up time describes the time that expires after the last detection of a motion until the
output is switched off. For example, with a follow-up time of 3 minutes, the light would be switched
on for at least 3 minutes with motion detection. Each new detection leads to a retriggering and thus
to a restart of the follow-up time..

Locking or enabling object

To lock or enable the alarm channel, you can activate a lock or enabling object. The lock object
switches off the channel with a 1, the enable object activates the alarm channel with a 1..

Separate switch object at night

This parameter displays a separate switch object for night mode..

Output object sends at

This parameter can be used to activate a sending filter for the output. If you want the output to send
only ON commands, you have to use the setting "only ON".

Output object sends cyclic

Table 24: Submenu - Brightness

In the menu "Brightness" the brightness measurement value can be corrected in percent. To make a
correction, proceed as follows:

 Measure the actual lux value at the installation location of the motion detector with a lux

meter

 Reading out the measured value of the motion detector

 Calculate the deviation: 1 −

 Enter the deviation as correction for the lux value

In addition, the transmission behaviour of the light value can be adjusted. The light value can be
transmitted either cyclically or in the case of changes..
