The flush-mounted device is connected to the 230-V power supply. A load (typically a light) can be connected to the electronic output. After the device has been connected and the power supply switched on, the device will need approx. 30 seconds for initialisation, after which it will be ready for operation. The following parameters can be adjusted using the infrared remote control: Brightness of the orientation light, sensitivity (range) of long range detection, walking test (detection field)/overrun time = 1 sec., threshold setting for max. ambient brightness (light will not be switched on if this value is exceeded), overrun time setting, Master / Slave switchover – if several Sensotec devices are used in combination, only the Master's brightness and the behaviour when switching off will be analysed. Blue and red LED signals provide the installer with programming assistance. If a coupling relay is attached to the output of the Gira Sensotec LED, loads such as wound or electronic transformers, compact fluorescent lamps, fluorescent lamps or an electric door operator can be connected. The output of the Gira Sensotec LED can also be connected to a KNX binary input if the dimming setting is at 100%.
