Individual switching
In individual switching, the presence detector as master
detects presence and brightness and controls lighting.
L’
Parallel switching / Master-Slave
If the detection area covered by a single presence detector
is insufficient (in larger rooms), then several detectors can
be operated in parallel by connecting the S and L‘ terminals.
Presence detection is performed by all detectors together. The
master measures the brightness and controls the lighting. The
other detectors (slaves) only provide presence information via
the L‘ terminal.
¾
At the slave devices set the potentiometer for time delay
(TIME) to 30 s and for switching value (LUX) to or deac-
tive the brightness measurement with remote control, press
button .
L
If the operating voltage remains at the S terminal < 1 sec.,
the master interprets this as a key signal. Operating vol-
tage > 2 sec. is interpreted as a slave signal and executed
correspondingly. For this reason the light does not switch
on until 2 sec. after a movement has been detected by the
slave device.

Push button control
The lighting can be manually switched on/off via a button. If
the light is switched on manually, it will remain on as long as
people are present (plus time delay). Then the light goes into
the set automatic mode. If the light is switched off manually,
it will remain off as long as people are present (plus time
delay). Then the light goes back to automatic mode.
Fully or semi-automatic device
Lighting control via the presence detector operates fully
automatically for increased comfort or semi-automatically
for greater energy savings. The lighting switches on and off
automatically as „fully automatic device“. In „Semi automatic“
mode, it must be switched on manually and switches off
automatically. Settings are entered via remote control.
Switching behaviour
Every time the power supply is switched on, the presence
detector runs through two phases that are shown on an LED
and the connected lighting:
1. Warm-up phase (1 min)
•
The red LED flashes at one second intervals, the switch
contact is closed (light on).
•
The detector does not react to push button commands
and remote control commands.
2. Operation
•
The detector is ready for operation (LED off), and when
no one is present, the light switch contact opens (light
off).
Installation instructions and detection area
As the detector reacts to variations in temperature, avoid the
following situations:
¾
Do not point the presence detector at objects with highly-
reflective surfaces such as mirrors, etc.
¾
Do not install the presence detector near heat sources such
as heating vents, air conditioners, lamps, etc.
¾
Do not point the presence detector at objects that move in
the wind such as curtains, large plants, etc.
¾
Pay attention to the direction of motion during the test run.
2,5 m
360°
Ø 2 m
Ø 8 m
L
recommended installation height: 2 – 4 m
L
Transverse detection area: 8 m (transversal to the detector)
L
Frontal detection area: 2 m (directly approaching the detector)
L
Detection area sitting: 2 m
L
Detection angle: 360°
5. Walking test
The walking test is used to test the detection area.
¾
Set the time delay potentiometer (TIME) to T (Test). The
presence detector only reacts to movements, brightness
measurement is switched off.
¾
Walk through the detection area. Every detected movement
is indicated by the LED, and the light switch contact closes.
When no one is present the light switch contact opens after
3 seconds.
L
If the walking test is carried out using the slave device, the
walking test must also be activated on the master device.
