1.1 Symbols used
► Instructions
> Reaction, result
→ Cross-reference
Important note
Non-compliance may result in malfunction or interference.
Information Supplementary note.
2 Safety instructions
• Installation, electrical connection, set-up, operation and maintenance of the unit
must be carried out by qualified personnel authorised by the machine operator.
3 Functions and features
Ultrasonic sensors detect objects of various materials without any contact.
Depending on the selected sensor, detected objects are signalled via switching
outputs or their distance is indicated by means of a proportional analogue signal.

7.3 Inverting the output response
► Press button > 6 s.
> LEDs flash (> 10 Hz).
> Output functions are inverted (NO becomes NC or vice versa).
7.4 Restore factory setting
► Align the device so that no echo is received.
► Go into the programming mode of the unit.
► Press button once for 1 s.
> LEDs flash shortly with 4 Hz.
8 Operation
► Check whether the unit operates correctly.
> Display by LEDs:
Green LED is lit. Echo is received.
Yellow LED P1 is lit. Output 1 is switched.
Yellow LED P2 is lit. Output 2 is switched.
Green LED flashes. Short circuit at the output.
The minimum distance between the “Proximity Switch Metal Enclosure“ and
any “External uninsulated live part“ shall be at least 12.7 mm.
