The sensor measures the brightness. The lighting conditions at the workplace are maintained at a user-adjustable set point by providing artificial light according to the amount of available daylight. If there is more than sufficient daylight, the lighting control switches off the luminaire. The TOUCH DIM sensor can be installed in luminaires (e.g. floor-standing luminaires), or by use of a flush device box with adequate cover also into the ceiling. Good workplace lighting makes the working environment more comfortable. Energy savings of up to 50% can be made compared with conventional workplace lighting. Safety and installation information The unit should be installed and tested only by a qualified electrician. Power to the units must be switched off before any work is undertaken. The relevant safety and accident prevention regulations must be observed. The TOUCH DIM sensor is used exclusively for controlling electronic control gear type QUICKTRONIC INTELLIGENT LI (QTi LI...DIM) or HALOTRONIC INTELLIGENT LI (HTi LI..DIM). No further control units may be operated on the control line. Other applications are not permitted. They may destroy the TOUCH DIM LS/PD LI and other equipment. The maximal number of ECG and the maximal overall cable length between push button, sensor and ECG has to be respected (see Technical data). If the control cable is wired with external voltage, the unit may be destroyed. The TOUCH DIM Sensor may only be supplied with AC operating voltage. This is particularly important to remember if UPS systems are used. page 2 OSRAM - operating instructions TOUCH DIM LS LI

4 Installation Installation hints The sensor is connected to a 3 wire cable which is admitted for mains voltage. Parallel connection of several sensors is not allowed. The sensor is typically installed in luminaires, ceiling installation is possible by use of a flush device box and an adequate cover. When installing the sensor, please note the following: Avoid placing the sensor where it is directly exposed to light from other sources as this will lead to incorrect measurements. The sensor should be installed centrally in the sphere of action, so that all controlled lumnaires contribute with the same proportion to the measured brightness.

5 Operation General functions Switching the luminaire on/off 1. Briefly press the switch once. The luminaire is switched on or off each time the switch is operated. Changing the brightness With the luminaire switched off: 1. Press the switch. Keep pressing the switch until the required brightness is reached. With the luminaire switched on: 1. Press the switch. Keep pressing the switch until the required brightness is reached. The luminaire goes on at minimum brightness. The longer the switch is pressed, the brighter the luminaire gets. When the switch is released the luminaire will remain at the brightness it has reached. The brightness will change. When the switch is released the luminaire will remain at the brightness it has reached. Switching between more and less brightness: 2. Release the switch then press it again. Keep pressing the switch until the required brightness is reached. Every time the switch is held down the unit toggles between more light and less light. Note: Changing the brightness deactivates brightness control. When the unit is switched on again brightness control is reactivated, if a set point value was is stored. Controlling brightness at the workplace Adjustment / Storage of the set point for brightness control 1. Change the brightness to the required level by holding down the switch. 2. Once the set point is reached, make a double click (switch pressed twice briefly within short time) within 30 s. The brightness will change. When the switch is released the luminaire will remain at the brightness it has reached. The brightness you have just set will be stored as the new set point. The luminaire will flash twice to confirm that this value has been stored. OSRAM - operating instructions TOUCH DIM LS LI page 5

6 Operation Deactivation of the brightness control Brightness control can be completely deactivated: 1. If the luminaire is switched on, switch off the luminaire by briefly pressing the switch. 2. Make a double click (switch pressed twice briefly within short time). The set point is erased and brightness control is now disabled and the luminaire will dim to 100%. To activate the brightness control again, store a new set point as described on the previous page. page 6 OSRAM - operating instructions TOUCH DIM LS LI

7 Appendix Troubleshooting The luminaire is not working. Possible cause: There is no power. Check if the luminaire is connected to power. The lamps are faulty. Replace them. The luminaire was switched off at the switch. Switch the luminaire on. The luminaire is not regulating its brightness to the set point. Possible cause: After setting the brightness you must press the switch twice within 30 seconds. If you press the switch later a set point will not be stored. Bear this time in mind. Brightness control is not started until 5 seconds after the set point has been set. Within this time any other switch operations are ignored. Bear this time in mind. Brightness control was deactivated by changing the brightness level with the switch. Switch the luminaire off and on again. Brightness control is deactivated because set point was erased. Store a new set point. The luminaire is not reacting as expected to switch operations. Possible cause: The switch is being pressed too long. Please note: Hold down the switch to change the brightness until the luminaire reaches the brightness level you want. For all other functions, just briefly press the switch. If you cannot remedy the problem, please contact the customer service department of your luminaire manufacturer. OSRAM - operating instructions TOUCH DIM LS LI page 7
