Description of application Control unit 301302
Description of software application:
– Switching and dimming behaviour adjustable by parameters.
– Dimming range can be restricted by a lower and upper limit value.
– Transmission of actual brightness value via the brightness value object.
– Transmission of actual switch status (0 or 1) via switch object and parameter „after switching ON/OFF object 0 sends its status“. That function is
used to control the status LED in the push-button.
– Switching ON by switching or dimming object or only by switching object adjustable.
– Dimming to or jumping to brightness value.
– Behaviour on bus voltage drop/recovery adjustable.
The control unit switches or dimms (via a 1 – 10 V control voltage) in dependance of the telegramms received via the KNX.
After receiving a switch ON telegram the max. brightness will be adjusted. The initial brightness, dimming speed as well as the dimming speed to
a brightness value can be adjusted by parameter.
The current brightness value can be read out (e.g. by a push-button in order to store a light scene). For that purpose the R-flag of object 4/5 must
be set in one device per group.
Furthermore, there is a parameter to select if the control unit shall be switched off by receiving a telegram with the brightness value = 0.
Additionally, the control unit switches OFF automatically if the brightness value falls below the adjusted setpoint.
This application is recommended for constant light controls with fluorescent lamps.
Constant light control:
When the device is configured as "Controller and dimmer", the control unit works in a constant light control operation. The actual brightness value
is evaluated via the special light sensor (ref.-no. 2092 LFX).
In that operation mode an additional object and parameters are visible. Generally, there are two different control methods:
1. The brightness setpoint is fixed and cannot be changed by the user.
2. The brightness setpoint can be changed by the user with the parameter "dimm brighter/darker...used as a new setpoint".
That new setpoint is active until the next switch command is transmitted.
Adjustment of the light sensor:
1. Avoid natural light, only the artificial light has to be adjusted to the desired value by dimming commands.
2. A telegram with the value "1" has to be transmitted to the object 6/7.
3. The brightness value measured by the light sensor is the new setpoint.
4. For testing dimm down the lighting, the control unit will dimm up to adjust the new setpoint.
Additional dimming actuators can be triggered on by the 1 Byte objects 4/5. The control unit will transmit the brightness value via these objects.
Now also other dimming actuators such as leading/trailing edge control dimmer can be integrated into the constant light control.
