LEDs red yellow green LED yellow push button receiver transmitter LED green push buttonENGLISH Mount the unit so that the mounting position cannot change (in particular avoid high vibrations!). Laser units with a very small light spot diameter are highly focussed; the slightest change in the mounting position will result in misalignment. Adjustment aid: For the alignment the transmitter incorporates an adjustment aid. By pressing the setting button on the transmitter the intensity of the transmitted light is increased so that the light spot is clearly visible. After pressing the button again the transmitted light is set again to normal intensity. If the button is not pressed again, the transmitted light is set to normal intensity after about 15 min. NB: Commissioning The through-beam sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the through-beam sensor can operate with maximum excess gain (highest contrast). The following setting procedures should only be necessary in less straight- forward applications, for example if partly transparent objects must be detected. Setting of the sensitivity with stationary objects

Press for about 2s until the red LED flashes. Activate the programming mode of the unit. The red LED goes out; the yellow and green LEDs flash alternately. The unit is in the programming mode.

receiver transmitterYou can also proceed in reverse order: first setting without the object, then with the object. If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged. If the setting button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the sensitivity being unchanged.

Set the sensitivity with object. Press once. The yellow and green LEDs go out for approx. 1s, then flash again alternately.

receiver transmitter Press once. The yellow and green LEDs go out for approx. 1s, after approx 3s the green LED is on. The unit is in the operating mode.

Set the sensitivity without object. receiver transmitterENGLISH Setting of the sensitivity with moving objects

During the measurement (about 1s) allow at least two objects to move through the detection area. Press once. The yellow and green LEDs go out for approx. 1s, then flash again alternately.

Press once. The yellow and green LEDs go out for approx. 1s, after approx. 3s the green LED is on. The unit is in the operating mode.

receiver transmitterIf the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operat- ing mode with the sensitivity being unchanged. If the setting button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the sensitivity being unchanged. Setting of the maximum sensitivity

• Go into the programming mode (step 1).

• Interrupt the light beam.

• Press the setting button twice (see steps 2 and 3). Programming the output function Operation Check the safe functioning of the unit. Display by LEDs and by the fun- ction check output.

LED green is lit Unit is ready for operation. LED yellow is lit Output is switched. LEDs yellow + red Flash alternately, 2 Hz: output short-circuited. Flash alternately, 1 Hz: internal malfunction (output is not switched). LED red is lit Error in object detection, e.g. maladjustment, soiling of the lenses. Press for 10s. The red LED starts to flash fast after 2s. Then the yellow and green LEDs flash alternately. After 8s all LEDs go off, the output function has chan- ged from light-on mode to dark-on mode (or vice versa). receiverENGLISH Function check output

• Switches in the case of incorrect object detection (error in object detection, maladjustment, soiling of the lenses) after approx. 4 s, it switches back approx. 4 s after the object is again correctly detect- ed.

• Immediately switches in the case of a short circuit of the switching output, it switches back approx. 2 s after the fault has been recti- fied.
