Brightness measurement
The presence detector measures artifi cial light and daylight
by means of three directed light measurements. The central
light measurement detects the brightness directly below the
detector (A), while the two other light measurements detect
the brightness close to the window (B) or in the interior (C).
The installation location is the reference point for the lighting
level. The brightness measurement can be adapted to the
conditions in a room with the room correction factor.

Each light measurement area maps a rectangle of about 2.0 x
3.5 m at table height. Depending on the operating mode, the
light measurements are assigned as followed:
•
2-channel: Window light measurement (B) is perma-
nently assigned to lighting channel C1 and interior light
measurement (C) to lighting channel C2
•
3-channel: As with 2-channel, but with free choice
between central light measurement (A) and integral light
measurement (average of light measurements A + B + C)
in the case of lighting channel C3
Switching
Direct light infl uences the light measurement. Avoid placing
fl oor lamps or suspended lighting directly below the detector.
Constant light control
The detector must be positioned in such a way that it only
detects artifi cial light that it controls itself. Artifi cial light that
is controlled by other detectors or manually switched work
lighting infl uence the brightness measurement of the detec-
tor. The detector must not be exposed to direct artifi cial light.
Switching operation
If the brightness measurement is deactivated, the light only
comes on when presence is detected (brightness setpoint
value set to “measurement off” via the remote control).
Suitable lamps
The presence detector is designed for the operation of fl uo-
rescent lamps, compact fl uorescent lamps, halogen/incande-
scent lamps and LEDs.
6. Installation
L
Note window/interior alignment!
Flush-mounted fi tting
The presence detector is fl ush-mounted using a size 1 stan-
dard fl ush-mounting installation socket.
Surface-mounted installation
A back box LMS MG SURFACE MNT FRAME (B29011002) is
available for surface mounted installation.
7. Connection
The presence detectors can be combined as master in indi-
vidual switching or as master/master in parallel switching.
Several push buttons can be connected to one control input.
Illuminated push buttons can only be used with neutral con-
ductor connection.
With the app in combination with app remote control lighting
channels C1 to C3 can be assigned to the required button
inputs S1 to S3 via the parameter <Terminal SX assignment>.
The input S3/P can be used for the master/master switching,
or as button input S3. The factory setting is „Parallel“.
Up to 50 DALI operating devices can be connected to each
master device. We recommend distributing the DALI operating
devices equally over the 3 external conductors.
L
All detectors and buttons must be connected to the same
external conductor.
Individual switching
In individual switching, the presence detector, as master,
detects presence and brightness and controls lighting.
