6. OPERATION
6.1 More than one sensor and more than one load
Manual ON/Automatic OFF mode
Pressing the auxiliary control allows the load to be switched on or off
manually. If the control is not pressed, the sensor will cut off the load
at the end of the time delay or when the light level threshold has been
reached.
Auto ON/OFF mode:
The load will be switched on and off automatically.
Option: It is possible to control the sensor by infrared remote control
using: Cat. Nos. 0 882 00/01/20/31/32/33.

7. SETTINGS
7.1 Detection parameters
Time delay: Length of time the load is on after detection.
Sensitivity: Detection range setting.
Modes:
Auto on/Auto off mode:
Comes on automatically:
- At the detection of a presence if there is an insufficient natural level of
light.
Turns off automatically:
- If no presence is detected and at the end of the time delay set.
- Or if the natural light level is sufficient (regulation activated)
Another detection causes automatic switch-on if there is insufficient
light.
Walk-through mode:
- If no presence is detected in the 20 seconds following an initial
detection, the product will cut off the load after 3 minutes.
- If another presence is detected in the 3 minutes following initial
detection, the device will cut off the load at the end of the set time
delay.
Manual on/Auto off mode:
Comes on via a manual switch, automatic switch off:
- Where no presence is detected and at the end of the time delay set.
After switch-off, any new detection within a 30 second period triggers
an automatic switch-on. The Restart function must be activated.
After 30 seconds the device is switched on via a manual switch.
Partial on/Group off mode:
Possibility of controlling one or more lighting points individually.
In this mode it is essential for a lighting group to be created:
- either by manual teach phase.
- or from the advanced configuration tool Cat. No. 882 30 using the
function "PnL capteur" (PnL sensor).
The sensor switches on the loads that are linked to it via the actuator.
Where there is no detection and at the end of the time delay it switches
off all loads in the group to which it belongs.

7.SETTINGS (continued)
7.1 Detection parameters (continued)
Detection system:
Initial detection: The load is switched on as soon as the first detection
occurs if the natural light level is below the light level threshold.
Maintain: The load remains active if another presence is detected.
Restart: In manual mode. After switch-off, any new detection within a
30 second period triggers an automatic switch-on.
After 30 seconds the device must be switched on manually.
Alarm: an audible signal is emitted before switch-off. (1 minute before,
then 30 seconds, then 10 seconds).
7.2 Light parameters
Light level threshold: Value at which the load comes on if the
natural light level is less than the setting.
Caution:
The device becomes a motion detector at 1275 lux.
Advanced mode:
Calibration: The surrounding light level measured with a luxmeter
must then be transmitted to the sensor (see data sheet
Cat. No. 0 882 30)
.Regulation: Automatic switch-off of the load 10 minutes after
the light level threshold is exceeded with an additional safety
threshold (to avoid lights switching off at the wrong moment).
Light contribution: Quantity of additional lux provided by the load
being switched on.
When the light contribution parameter is set to "Auto" (value 0) on the
configuration tool Cat. No. 0 882 30 the sensor automatically calculates
the light contribution.

7.3 Modifying the parameters using the configuration tools
• 0 882 35: Simplified configuration tool
• 0 882 30: Advanced configuration tool
When the sensor receives an IR command using the configuration tool
it emits a beep acknowledging the modification.
For more information about setting parameters, refer to the data sheet
for the configuration tool Cat. No. 0 882 30.

1st press: Short press on LEARN: the LED flashes slowly.
2nd press: Press and hold down LEARN for 10 seconds until the LED
flashes quickly.
8. CONFIGURATION
8.1 Physical configuration
BUS SCS sensor Physical Configuration
The physical configuration only authorises point-to-point addressing:
one single actuator can be controlled via the sensor.
A: Area (0 –A)
PL: Light point (0 – F)
M: Mode (0 – 4)
S: Sensitivity of the motion detector (0 – 3)
T: Time delay (0 – 9)
D: Light level threshold or daylight set point (0 – 5)
The A and PL configurator: addressing
The A and PL configurators provide the address of the actuator to be
controlled.
NB:
- If the product does not have the A and PL configurators positioned
then it is not configured.
- The configuration A=0 and PL=0 does not exist
The M configurator: the modes
The M configurator allows the user to choose the product's modes of
operation:
Mconfigurator Mode
No configurator Automatic On/Off mode & without setting
range & with presence detection
1Automatic On/Off mode & light level measure
& without presence detection
2Supervision mode
3Automatic On/Off mode & setting range &
with detection
4Automatic On/Off mode & setting range &
without detection

PROBLEM CAUSES SOLUTIONS
Lighting stays on when there is no-one present Sources of interference can cause false tripping,
such as: air current, vibrations, radiators
1- Reduce the sensitivity level
2- If the interference continues: using the
configuration tool, go into the Detection
system parameters, select Maintain and then
choose PIR and US
3- If the interference still continues, move the
sensor away from sources of interference
Lighting does not switch off during the day
when there is an adequate level of natural light
Regulation function not active
Light level threshold set too high
Light contribution is too high
Activate the regulation function
Reduce the light level threshold
Check that the sensor is positioned correctly in
relation to the window
Decrease the power of the luminaires
Lighting switches off when there are people
present and the natural light level is not
adequate (darkness)
Time delay too short
Detection sensitivity too low
Light level threshold too low
Increase the time delay
10 to 1 minutes is recommended for work areas
Increase the sensitivity
Move the sensor closer to the work area
Increase the threshold
