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...

3 “Settings” menu Here it is possible to configure the programming mode between ETS mode (S-Mode) and Easy mode by the Easy controller software (Kit GW90837, Kit GW90838, GW90840) and the other functional parameters (see Diag 3.1). 3.1.1 Programming mode This parameter determines the programming mode of the device: • ETS mode Select this value if you want to configure the device with ETS (S-Mode); all the configuration parameters are now visible. • Easy mode Select this value if you want to configure the device with the Easy controller software. Remember to download the application program...

3.1.2 Cycle time When the device detects movement and after assessing the brightness level detected by the twilight sensor, it sends a movement start telegram; from this moment in time, the value on the cycle time counter decrease. During the cycle time, any movement detected will not trigger the sending of a bus telegram as this would create an overflow on the bus line, so the device repeat the start telegram at the end of each cycle time; therefore, if the cycle time lapses and there is constant movement, the device will send another start telegram (see Diag. 3.2). Cycle time Start...

Easy movement detector with twilight sensor - 7

Communication objects The Settings menu makes the following communication object visible (See Diag. 3.3.): 3.2.1 Timed switch The device sends START temporization commands to the bus through this communication object following a movement detection. The enabled flags are C (communication), R (read by bus) and T (transmission). The standard format of the object is 1.010 DPT_Start, the size of the object is 1 bit and the information it contains is START temporization. 3.2.2 Status feedback Through this communication object, the device receives status feedbacks for the devices it controls,...
