9.4.6 General parameters - Brightness-value threshold internal (lux)
Options:
1 .. 20 .. 1000
- This is used to set the desired brightness of the room. Below this threshold - hysteresis the presence detector switched at movement. The presence detector
switches off again when the measured brightness - artificial light component = brightness-value thr hysteresis.
Note:
The value entered here is smaller than the control value set in the room via the luxmeter. This depends on the calibration of the brightness sensor for brightness
detection settings. When the brightness adjustment is used there, the desired brightness must be set here for the working area.
Example:
The brightness at the top of the desk is to be 500 lux. The presence detector, however, measures the required brightness at the position it is mounted( e.g. on
the ceiling it only measures 20 lux). This means that there is a difference between the brightness of light at the desk and the ceiling.
If the object is now used for brightness adjustment (daylight) or the objects brightness adjustment (output 1 / 2), one can enter 500 lux here (after calibration
of the brightness sensor).
9.4.7 General parameters - Hysteresis (%)
Options:
10 .. 12 .. 100
- Switching threshold = brightness threshold ± hysteresis
The hysteresis prevents excessive switching when the current ambient brightness is close to the brightness threshold.
9.4.8 General parameters - Switch-off delay (hh:mm:ss)
Options:
0.00.10 .. 0.03.00 .. 18.12.15
- The switch-off delay is slightly different here than for the movement detector. Here the switch-off delay is started when the sensors no longer detect move-
ment. When the presence detector detects movement after the switch-off delay, the switch-off delay timer is re-triggered.
9.4.9 General parameters - Fade in extended parameters
Options:
No
Yes
-
No
: One only sees the most important parameters for setting the presence detector.
-
Yes
: One sees all parameters, also those one may not need in most cases, e.g.:
› Extended parameters
› Sensor selection
› Enable
- No: Only the most important parameters for setting the presence detector are displayed.
- Yes: All parameters are displayed, also those that are not required in most cases.
Examples:
› Extended parameters
› Sensor selection
› Enable
9.4.10 Extended parameters - Operating mode
Options:
Automatic mode
Automatic switch-off
Movement-dependent operation
-
Automatic
: automatic switch-on and switch-off
-
Automatic switch-off
: manual switch-on and automatic switch-off
-
Operation independent of movement
: switch-on and switch-off independent of brightness
-
Automatic
: In "Automatic" mode, in case it is too dark, the presence detector switches on automatically when detecting a movement. The switch-off is ef-
fected after the set switch-off delay beginning from the most recent detection.
–
Automatic switch-off
: In "Automatic switch-off" mode the presence detector must be switched on manually via the automatic/manual object. The switch-off
is effected automatically under consideration of the switch-off delay.
–
Operation independent of movement
: In operating mode "Operation independent of movement" the presence detector switches On and Off only on the
basis of brightness ± hysteresis. Activation / deactivation via object automatic/manual off.
