USER MANUAL OD5012 IFM

5Functions and features The colour sensor detects coloured objects and materials without contact in diffuse- reflection or retro-reflective mode. Mounting Mount the colour sensor in such a way that the object to be detected makes as lit- tle lateral and vertical movement as possible. Consider the specified sensing range. Transparent objects can be better detected by means of a suitable reflector. Mount the reflector opposite the colour sensor so that the light beam strikes the centre of the reflector. In the case of moving objects the direction of movement should be transverse to the sensor to achieve optimum repeatability (this only applies to sensors with a sensing range of 12.5 mm). In the case of shiny object surfaces the sensor should be mounted at an angle of in- clination of 10 ... 30° referred to the object. Electrical connection Disconnect power and connect the sensor as indicated on the type label. The input AT (activation trigger = synchronising signal) can be used for triggering the sensor via an external voltage signal. Sensor deactivated: 12 V < AT < U Vmax Sensor activated: AT ≤ 2 V or unused Response time: < 0.2 ms The input ET (External Teach) can be used for programming the reference colour for the output out1 via an external voltage signal. Activate teach-in: 12 V < ET < U Vmax RUN mode: ET ≤ 2 V or unused Pulse duration: 0.5ms 10...30° 5Controls and indicators Setting and programming

LED operation display LED function display programming selector switch teach button rotary switch colour tolerance Set the rotary switch colour tolerance (Tolerance) to the requested colour resolu- tion. 1 = small tolerance range for detecting small colour shades 3 = basic setting 5 = large tolerance range for detecting colour families or colour groups

Set the programming selector switch to the colour channel to be adjusted (switch- ing output Out1, Out2 or Out3). For units with only one switching output set the programming selector switch to Out1. Press the Teach button. A red light spot shows on the object. Release the Teach button, the light spot disappears.

Out Run Delay Run After a successful teach-in operation the function display (Out/OK) comes on. If it flashes, the intensity is too high. Incline the sensor by 10 ... 30° and repeat the teach-in operation. If the function display is not lit, the inten- sity is too low. Select a lighter mark. Only for retro-reflective mode If the function display flashes, increase the distance sensor/object or sensor/reflector or use a smaller reflector. If the function display is not lit, reduce the distance sensor/object or sensor/reflector or use a larger reflector. Set the programming selector switch to Run or Run Delay (20 ms switch-off delay). For sensors with several switching outputs repeat the programming for the other switching outputs accordingly. The colour tolerance can be individually determined for each switching output. The sensor is ready for operation. If the switching output is activated, the function display is lit (Out/OK). If the tolerance setting is to be changed subsequently, programming must be made again with the tolerance setting changed.
