Define. Transfer. Analyse. Users of the 4service NFC app can configure and analyse Tridonic LED drivers with NFC interface free of charge. Application The 4service NFC app enables quick and easy configuration and analysis of Tridonic LED drivers. This makes the work of installation engineers, maintenance officers and employees in similar fields significantly easier. Functions The following functions can be configured via the app, provided they are supported by the respective Tridonic product. Set the driver parameters: - LED output current Set the LED output current (in mA) to adjust the brightness - Device operating mode Selection of the device operating mode (DALI, corridorFUNCTION, chronoSTEP, etc.). - DALI addressing Set the DALI short address - corridorFUNCTION Configuration of the corridorFUNCTION (light level, fade times, etc.). - chronoSTEP Configuration of the chronoSTEP profiles EZ easy addressing decoder An addressing tool is available to convert the Bi-colour LED binary identification signal to a DALI address of between 0 to 63. Easily transfer driver parameter settings With the copy function, you can quickly and easily copy a device's settings to identical devices. This saves time when replacing faulty devices and when commissioning several identical luminaires. Transfer configurations from deviceGENERATOR With the app, configuration files that were created with the deviceGENERATOR (ending: *.trgf) can also be transferred on LED drivers. Driver analysis If an LED driver is faulty, the data memory can be readout. This means an initial analysis of the causes is already possible on site. Product information Retrieve further information about Tridonic products, simply scan the NFC tag or the QR code on Tridonic devices. The following prerequisites must be met before you can use the app: - Use of an LED driver with NFC interface from Tridonic. - NFC reader with Bluetooth connection from FEIG ELECTRONIC or Tertium Technologies. Alternatively, the internal NFC reader can also be used on different smartphones. - Active Internet connection for first-time use and for updates. An Internet connection is not absolutely necessary for ongoing operation. To ensure that the app works properly, however, the device-specific data must always be current, i.e. regularly updated. - If any of the driver's functions are protected by the luminaire manufacturer (e.g. by a password), these cannot be changed even with the app. The 4service NFC app is itself is free of charge. But costs might be incurred for the required internet connection.
