Setpoint
Note:
The following information is relevant only if no adjustment of brightness has been carried out.
Please note that the lux value to be set in the parameters does not correspond to the value required at the height of the desk. The light sensor is installed on
the ceiling and can only measure the luminosity that is reflected from the opposite surfaces. The setpoint to be entered is therefore lower than the light value at
the height of the work station. Dim the lights to the desired intensity. Then save the measured light value via the memory object of the presence detector. The
stored value can also be read via the object for the setpoint.
Outputs
The presence detector can also regulate two independent light circuits per channel via the two outputs. The value of output 2 results from the value of output
1 and the respective proportionality factor. If the required setpoint is not reached, control continues beyond the factor.
For example:
An office is fitted with two light rows. Output 1 controls the light row in the darker part of the room. Light row 2 in the front window area is connected to output 2.
For the maximum brightness during the day a proportional factor of 70% is sufficient for output 2. During the night the full brightness in the room is not sufficient
for output 1 and output 2. Output 2 would now control beyond the proportional factor until the setpoint or the full brightness of the lamp has been reached.
Switch-off delay
The presence detector will switch off or dim the lamps in the room if no movement is detected. A switch-off delay can be set to prevent the lamp from being
switched off immediately. This time starts as soon as movement is no longer detected. If movement is detected again within this period, the switch-off delay
is reset.
Hysteresis
The hysteresis is a percentage value (+/-) that is related to the setpoint in lux. The hysteresis is a tolerance for maintaining the setpoint. The preset value is
sufficient for most applications.
