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
output or their distance is indicated by means of a proportional analogue signal.

1: Status LED (yellow) 2: Echo LED (green)
►Position object.
►Align the ultrasonic sensor so that it directly faces the object or the background
and secure it to a bracket.
> Object / background is detected when the echo LED (green) lights.

Sound-absorbing surfaces have a negative effect on a reliable function.
During installation of the device, consider the blind zone.
5 Electrical connection
►Disconnect power.

8.3 Inverting the output response
►Connect teach input > 6 s → 7 Wire programming.
> LED flashes (> 10 Hz).
Inverted output function (switching output: NO changes to NC or vice versa /
Analouge output: low...high signal changes to wird high... low signal or vice versa ).
8.4 Restore factory setting
►Align the device so that no echo is received.
►Go into the programming mode of the unit.
►Connect teach input 1 s → 7 Wire programming.
> LED flashes shortly with 4 Hz.
9 Operation
►Check whether the unit operates correctly.
> Display by LEDs:
Green LED is lit. Echo is received.
Yellow LED is lit Output is switched / object is into the teached operating range .
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.
