9.5 "Constant light controller" application
9.5.1 General parameters - Output is of type
Options:
1 byte 0...100 %
1 byte 0...255
-
1 byte 0...100 %
: For activating dimmers.
-
1 byte 0...255
: For actuators, which are activated with a value of between 0 and 255.
Note:
If the type of output is changed, also the options for setting the parameters change:
› Bottom limit output 1
› Upper limit output 1
› Control starts at
› Value for switching off
In this manual only values for the 1-byte 0 - 100% setting are described.
9.5.2 General parameters - Bottom limit output 1 (%)
Options:
0 .. 100
- Here the bottom control limit is specified and up to which minimum value a dimmer is controlled.
9.5.3 General parameters - Upper limit output 1 (%)
Options:
0 .. 100
- Here the upper control limit is specified and up to which maximum value a dimmer is controlled.
9.5.4 General parameters - Control starts at (%)
Options:
1 .. 50 .. 100
- Here the value is specified at which the control starts and the lighting is switched on.
9.5.5 General parameters - Control speed (mm:ss)
Options:
2.30 .. 10.00 .. 20.00
- Here the time is specified which the control requires to get from 0 to the upper limit output value. Example: If the control speed is on 10:00 and the lighting
is switched on with 50% and the upper limit is 100%, the control requires 5 minutes to get from 50% to 100%. Vice versa, the control requires 10 minutes to
regulate from 100% to 0%.
9.5.6 General parameters - Setpoint brightness (lux)
Options:
1 .. 400 .. 1000
- Here the desired brightness of the room is to be set. Below this threshold - hysteresis the presence detector starts the control and starts to adjust the light
until the setpoint has been reached again. The presence detector will not switch off but regulate against the bottom control limit. A switch-off takes place only
when the limit = 0 or the switch-off delay has expired.
Note:
For a well-functioning constant light controller it is absolutely essential to calibrate the brightness sensors. The calibration is carried out via the brightness
detection parameter. Here it is to be noted that the presence detector does not measure the brightness of the luxmeter on the working area (table), but the
reflected brightness, which can, depending on the reflecting area, can be lower.
Procedure:
• Switch of the artificial light/shield out the daylight
• Send the value measured with the luxmeter via the object
Similar procedure for daylight
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, one can (after calibration of the brightness sensor) enter 500 lux here.
