USER MANUAL OL5022 IFM

LEDs red, yellow, green setting button yellow LEDMount 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 To make alignment easier the intensity of the light spot is increased during the setting until it becomes clearly visible. In the operating mode (after step 3 of the setting) the transmitted light is set to normal intensity. NB: Commissioning The retro-reflective sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the retro-reflective 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.

8You 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. Setting of the sensitivity with moving objects ENGLISH Press once. The yellow and green LEDs go out for approx. 1s, then the green LED is on. The unit is in the operating mode.

Set the sensitivity without object. 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.

Set the sensitivity with object. Press once. The yellow and green LEDs go out for approx. 1s, then flash again alternately. 2If 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. Setting of the maximum sensitivity

• Go into the programming mode (step 1).

• Align the unit so that no light is reflected.

• Press the setting button twice (see steps 2 and 3). During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. 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, then the green LED is on. The unit is in the operating mode.

During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. 10Programming the output function Operation Check the safe functioning of the diffuse reflection sensor. Display by LEDs and by the function check output. 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.
