11.5.17 Extended parameters — Used brightness
Options:
– Internal: The presence detector uses its own measured brightness and brightness-value
threshold to decide whether the presence detector is to be activated or deactivated.
– External: A 2-byte "external brightness" (input) communication object is enabled. The
presence detector uses this external measured brightness and the "brightness-value
threshold" (lux) parameter to decide whether the presence detector is to be activated or
deactivated.
11.5.18 Extended parameters — Dimming step size brighter (1 to 15)
Options:
– Here the step size for increasing the dimming value during dimming brighter is specified.
The step size is relative to the value range of 1 - 255.
11.5.19 Extended parameters — Dimming step size darker (1 to 15)
Options:
– Here the step size for reducing the dimming value during dimming darker is specified.
Note
If the dimming step size is set too high, the dimming steps will be clearly visible
in the lighting.
11.5.20 Extended parameters — Use of output 2
Options:
– No: There is only output 1, which sends its telegrams to an actuator.
– Yes: An "output 2" communication object (output) is being enabled. The constant light
controller now regulates the brightness with two outputs (while the second output is used
proportional to the first out) in dependence of brightness. If the measured brightness is less
than the setpoint, the value of the first output is increased up to the upper limit of output 1.
During this control phase the second output is controlled proportional. If the setpoint still has
not been reached, the value of the second output is increased up to the upper limit of
output 2.
If the measured brightness is higher than the setpoint, the value of the second output is
reduced first up the upper limit of "output 1 x proportional factor". If the setpoint still has not
been reached, output 1 is lowered up to reaching the lower limit of output 1. During this
control phase the second output is controlled proportional. The bottom value of the second
output is limited by the lower limit output 2 parameter. When appropriately parameterised
the constant light controller can also switch off the associated dimming actuator.
