[. . . ] If the sensor is set to a bar chart display, the distance from the measured object is displayed as a green LED bar chart. The switching status and the stability of the two outputs are signalled as follows by two LEDs, visible from the top and the front of the sensor: Yellow LED (Output 1) ON Object stably detected Blinking Object not stable detected OFF No object within range Red LED (Output 2) ON Object stably detected Blinking Object not stable detected OFF No object within range Status LED ON Set-up menu selected Blinking Menu level with change of setting distance OFF RUN (normal) mode Operation Setting the switching points The switching points can either be user set (Teach-in mode) with a measured object positioned at the corresponding distance or can be set using the setting input, for remote setting. For each output of the sensor (up to two), up to two switching points can be user set. Only one switching point is active in the foreground and background suppression modes. For the 2-point window evaluation mode, two switching points must be set. Teaching the switching points in the normal mode The sensor is set at the factory for both outputs to BGS, light on. Place the target object in front of the sensor at the desired position. Teach the switching point for output 1: · Beginning with the key, press it simultaneously with the ENTER key. point D set 5Et 1. ) In the 2-point window evaluation mode, two switching points (A/B and C/D) can be set for each output. In the foreground and background suppression modes, only one switching point (A and C) can be set for each output. Then, only these switching points, A and C, can be set in the TEACH menu path. 2. ) If connector pin 2 is set as an input, only the switching points for Output 1 can be set.

If the switch-on/off delay is off in the OPTIONS menu path, the switch-on/off delay parameters do not appear in the SET menu path. The outputs behave differently depending on the switch-off delay functionthat is set in the OPTIONS menu path. [. . . ] If necessary a trigger signal or timer function has to be applied. 5° . . . 10° 90° detection object The sensor must be fitted so that: · It is correctly aligned before it is adjusted · It is protected as far as possible against vibration and shock · It is protected as far as possible against extraneous incident light · It is protected as far as possible against damage and soiling · Electrical connection is possible · It is as accessible as far as possible for maintenance work · Operation of the push buttons is possible · The display is visible. If there is a reflecting surface in parallel with the sensor's optical axis, this might lead to unstable switching states. Therefore, reflecting objects within the sensor's optical axis should be avoided. If this should not be possible, the reflecting surface should not be parallel to the sensor's optical axis, but should be rotated by at least 10°. [. . . ]
