The installation and maintenance of indoor and outdoor luminaires with NFC technology is as easy as it gets – thanks to the Tuner4TRONIC® Field app. The Tuner4TRONIC® Field app can be used for programming compatible INVENTRONICS NFC LED drivers in the Field via NFC (Near-Field Communication) – wirelessly and without mains voltage. In most cases, it is possible to readout the driver’s configuration even after the device’s failure. With the Tuner4TRONIC® Field app, certain luminaire settings can be easily adjusted according to the specific needs and within a predefined range set by the luminaire manufacturer. For indoor and outdoor applications, a typical example is the adjustment of the light output depending on the required application. Using outdoor drivers, the dimming levels can be changed in order to optimize energy savings and you can also disable the dimming functionality for special applications such as roundabouts or pedestrian crossings. In addition, using the copy and paste function of the app, the settings of the original luminaire (indoor and outdoor) can be easily transferred to the new one in a matter of seconds, making the luminaire replacement more efficient than ever before. The following features are provided by the T4T-Field app: - Adjust the light output in percentage, lumens, and milliamperes - Edit constant lumen output (CLO) - Adjust the automatic dimming levels, toggle dimming on/off (outdoor drivers only) - Enter Luminaire Info (Text, GPS, QR) - Copy and paste configurations from one LED driver to another - Load LED driver configurations shared by e-mails - Show a report of an LED driver’s configuration and send it via e-mail as a CSV file - Show a report of an LED driver’s monitoring data (D4i) and send it via e-mail as a CSV file - Open the data sheet by scanning the QR code on the driver List of supported LED drivers: https://www.tuner4tronic.com/ddstore/#/field Support is available at T4Tsupport@inventronicsglobal.com Important Note: This app is part of a larger system and does not function as a standalone application. A compatible Inventronics OT LED driver with an NFC interface is required to use this app. For more information, please contact your local INVENTRONICS sales representative.
