2 Application
The Easy movement detector with twilight sensor allows you to send timed activation commands to
actuator devices using the KNX/EIB bus through which it connects to the Home Automation system,
according to the movements detected and the light in the environment where the device is installed,
measured by the two built-in sensors.
The IR movement detector function and the twilight sensor function work together and it is not possible to
separate them; however, if you turn the potentiometer for local regulation of brightness threshold on the front
of the device completely on the right, you can almost exclude the twilight sensor function (set the brightness
threshold to the maximum value, about 500 lux), letting the IR movement detector function ON.
It is also possible to enable/disable the function that sends commands following movement detection, trough
an apposite communication object.
The device is fitted with two trimmers, one to set the brightness threshold and the other to modify the cycle
time (that will be analysed in detail further on) and a pilot light backlit by a green led which indicates when a
start movement telegram is sent.
The device manages a safety intermission which excludes the IR sensor for 5 seconds when the
commanded actuator switches OFF (it requires the commanded actuator to send its status information). This
intends to prevent undesired activation, for instance caused by the switching off of an electrical load with
high heat emission.
It is possible to set the functions on the device so that they activate only movement detection when the
actuator to be commanded is ON (conditioned detection). This function mode allows you, for instance, to
switch on lights in the traditional manner (using a button or similar fitting) whilst guaranteeing the automatic
switch-off function once the area covered by the movement sensors is liberated.
This manual refers solely to the configuration using the ETS software. Please refer to the INSTALLATION
AND USER MANUAL supplied with the product for instructions on how to adjust and use the trimmers fitted
on the device.
2.1 Limits to the associations
Maximum number of group addresses: 40
Maximum number of logical associations: 40
This means that it could be possible to define maximum 40 group addresses and realize maximum 40
associations between group addresses and communication objects.
