Project design and programming
This function enables constant lighting control. It is only available for the
Light Controller Module LR/M 1.6.1. Further explanations about the function
can be found in section 3.1.
An ON telegram at the object "Telegr. switch" always activates the control
function. The active control dims the lighting so that the difference between
the actual value and the setpoint value of the light sensor is as small as
possible.
Behaviour of the function "Lighting control" during and after voltage failures:
Bus voltage failure
Bus voltage recovery
Supply voltage failure
Supply voltage recovery
Measured value of light
sensor
Actual value of light sensor
Setpoint value
Master/slave mode
Control active/inactive
Behaviour of the output as defined in the "General"
parameter window. The control function is inactive.
Status of the lighting control as before bus voltage failure;
setpoint value is restored
No function
Status of the lighting control can be parameterised;
setpoint is adopted from the parameters
This is the brightness value measured directly by a light
sensor.
This is the currently measured brightness value of the light
sensor.
This is the definitive brightness setpoint for the lighting
control. The lighting control tries to align the actual value of
the light sensor with the setpoint.
It is possible for the light controller to integrate other
dimming actuators in the control function. In this case, the
light controller (so-called "master") controls the other
dimming actuators (so-called "slaves") directly via the object
"Slave brightness value".
The lighting control can be deactivated by the user so that it
can be manually operated. When the control is inactive, the
light controller behaves like a normal dimming actuator
except that the value "1" at the object "Telegr. switch"
always activates the control function again.
