Description Purpose and application The TOUCH DIM LS LI sensor regulates the brightness at the workplace and in office areas to increase the working comfort and to save energy. TOUCH DIM LS LI The sensor can be installed in luminaires (e.g. floor standing luminaires) or in false ceilings. Function A The sensor measures the brightness in the area to be regulated and keeps this to an adjustable set value by introducing artificial light according to the amount of daylight available. B As the amount of daylight increases, artificial lighting is reduced. Design The sensor is made up of the following components: • Light sensor (A) • Housing (B) • Connections (C) for signal line, neutral conductor and phase Light sensor Operating instructions C Operation Symbols Pushbutton on the luminaire Luminaire on Switch on Luminaire off Switch off Luminaire flashes Short press (< 0.5 s) Brightness with automat. control Long press (0.5 – 4 s) Confirmation of the setting Double-click Manual dimming 2x < 30 s 1 2 3 Switching luminaire on and off 2x < 30 s 1 2 Via short press. 3 Note: The luminaire is first switched on with minimum brightness.

If you cannot remedy the fault, please contact the Customer Service department of the luminaire manufacturer. Luminaire does not function No mains voltage. à Use a voltage tester to check for mains voltage. Illuminant is faulty. à Replace the illuminant. The luminaire was switched off via the pushbutton. à Switch on the luminaire. The sensor is exposed to excessive amounts of ambient light. à Hold the sensor closed and observe the behaviour of the luminaire. Brightness is not adjusted to the selected set value The pushbutton was not pressed within 30 seconds after the setpoint was adjusted à Double-click within 30 seconds after dimming manually. Brightness control was not started until 5 seconds after the setpoint was adjusted. à Wait for the delay period to elapse. Brightness control was deactivated by a manual operation. à Switch the luminaire off and on again. No setpoint was saved. à Save a new setpoint. Luminaire does not react as expected to the press of a button The pushbutton was pressed too long or too short. à See Changing the brightness manually.
