► For PNP units (e .g . O2D220) use trigger sensors, illumination units and control-
lers with PNP inputs and outputs .
► For NPN units (e .g . O2D227) use trigger sensors, illumination units and con-
trollers with NPN inputs and outputs .
6.3 External illumination
► Connect external illumination to the trigger output of the device .
Example

6.4 External trigger source
► Connect an external trigger source (e .g . a diffuse reflection sensor) to the trig-
ger input of the device .
If you use an external trigger source (e .g . a diffuse reflection sensor),
connect the trigger signal to the trigger input of the sensor . If you use
external illumination, it must be controlled via the trigger output of the
sensor .Depending on the device setting, one of four configuration files
saved in the sensor can be selected via two switching inputs . Information
about the test result is provided via switching outputs .
