Photoelectric distance sensor
OGD25x OGD55x
11
Switches off when the object is detected ([OUx] = [Fnc])
If the measured value is between the switch point “bright” [bSPx] and the switch point “dark" [dSPx],
the output is switched off (if [OUx] = [Fnc]).
The parameters [bSPx] and [dSPx] can also be set via the teach function. The reset points are
set dynamically by the sensor.
The minimum distance between [bSPx] and [dSPx] is 1 %.
Condition: [dSPx] < [bSPx]
e.g. the teaching of [dSPx] > [bSPx] will not be adopted by the sensor.

Final value of the measuring range
In the set measuring range the output signal is between 4 and 20 mA.
Faults are also displayed:
•
Faults at [SELx] = [dist]:
– Too much light or object too near: 3.5 mA for rising edge ([ASP]]< [AEP]), 20.5 mA for falling
edge ([ASP] > [AEP]).
– Object too far or no object present: 20.5 mA for rising edge; 3.5 mA for falling edge.
