7. SETTINGS (continued)
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 by using the function
"PnL capteur" (PnL detector).
The detector switches the loads on 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.
Initial detection: The load is switched on with the first detection made.
Maintain: The load remains active if any new presence is detected.
Retrigger: Function allowing automatic start of the product at the end of
30 seconds following the load being switched off.
On being switched off any new detection within a 30 second period will cause
the device to be switched on automatically.
After 30 seconds the device must be switched on manually.
Calibration: The surrounding level of light measured with a luxmeter will then
have to be transmitted to the detector.
Light regulation: Automatic switch-off of the load 10 minutes after the Daylight
setpointis exceeded. If the level of light is less than the light level threshold, the
load is activated automatically after 20 seconds.
Provision of light: Quantity of additional lux brought in by the load being
switched on.
- Modification of the parameters by the configuration tools
•882 35: Simplified configuration tool
•882 30: Advanced configuration tool
When the detector receives an PIR command using the configuration
tool it emits a beep acknowledging the modification.
- Return to factory settings:
1st press: Where LEARN is pressed for a short period the LED
flashes slowly.
2nd press: Keep LEARN pressed down for 10 seconds until the LED
flashes quickly.
7. SETTINGS
- Parameters:
Time delay: Length of time the load is on after a detection is made.
Sensitivity: Detection range setting.
Light level threshold: Value at which the load comes on if light is less than the
setting and goes off if it is above this threshold.
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 there is a sufficient natural level of light (activated setting).
Any new detection causes an automatic switch on if there is insufficient light.
Walkthrough:
- If there is no presence detected in the 3 minutes following an initial detection,
the product will cut off after 3 minutes.
- If a new presence is detected in the 3 minutes following the initial detection, the
device will cut off at the end of the time delay set.
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.
Following switch-off any new detection within a 30 second period will cause the
device to be switched on automatically.
After 30 seconds the device is switched on via a manual switch.
