The device series NT17/NT18 (modular installations) and KT2E/KT3E (lighting fixtures installations) unites most of present actual requirements on lighting control in just one device. These devices allow the manual control BRIGHTER-DARKER through pushbutton and the automatic Brightness-Constant Light Control through a Light Sensor. It is also available as a version with additional Light Value-Preset that stores up to 4 Light Values which the user can simply store and retrieve through a pushbutton.

In Automatic-Operation all devices switches OFF after 7 min. through the integrated relay if artificial-light-minimum is reached and there is sufficient daylight. The re-ON-switching at descending daylight is done automatically, but can be prevented through a re-ON-switching lock (jumper or switch at the item).

NT 18

Functions: BRIGHTER - DARKER - 4x PRESET - AUTOMATIC - ON/OFF
Construction: Modular Installations (DIN rails)

The operation is done through 6 various pushbuttons (installation buttons) or our tableau FS6V. By pressing the Pushbutton 1 briefly it switches ON/OFF, by pressing the button longer it dims alternately BRIGHTER-DARKER. Pushbutton 2 is for the Automatic-Constant Light Control modus. Pushbuttons 3-6 serves for storing and retrieving the Presets.
The integrated relay can switch a load of max. 6A, for larger load it serves for switching a power relay.

The desired Light-Value, which should be kept constantly, can be adjusted through the Dimm-Button 1 and stored by pressing the Automatic-Button 2 for more than 3 sec. Storing the Preset Values goes the same way, the desired brightness is choosen with the Dimm-Button and can be stored by pressing the designated Preset-Button for 3 sec.

Since the operation of the Preset-Functions are done through coded commands, by using other buttons instead of our tableau you need to use the encoder type ENC1, which is available as accessory and can be inserted in the wallbox behind the installation-buttons (small measurement 30x20x10mm).

KT 3E

Functions: BRIGHTER-DARKER-4x PRESET-AUTOMATIC-ON/OFF

The operations are made through any of 2 pushbuttons (installation buttons) only, by pressing button 1 briefly it switches ON/OFF and by pressing the button longer it dimms alternately BRIGHTER-DARKER. The other pushbutton calls the Automatic-Constant Light Control modus.
The integrated relay can switch a load of max. 6A, for larger load it serves for switching a power relay.
The desired Light-Value, which should be kept constantly, can be adjusted through the Dimm-Button 1 and stored by pressing the Automatic-Button 2 for more than 3 sec.
