800 mm; (values referred to prismatic reflector with Ø 80 mm).
2 Installation
Place prismatic reflector / reflective tape in desired position. Align the photocell
and fasten to a mounting bracket with the lock nuts provided.
Maximum range is only achieved with precise alignment.

flashing, 3 Hz: output short-circuited
flashing, 1 Hz: internal malfunction (output is not switched)
Sensor with plug
LED green supply voltage O.K.
LED yellow output switched
LED red error in object detection, e.g. maladjustment, soiling of the lenses
LED yellow + red flashing alternately, 3 Hz: output short-circuited
flashing alternately, 1 Hz: internal malfunction (output is not switched)
5 Maintenance
Keep the lens of the sensor free from soiling.
