Light grid

Safety information

The device must only be operated with Safety Extra Low Voltage (SELV) with safe electrical disconnection. Intervention and

repairs must only be carried out by your suppliers.

The system must be serviced and checked regularly.

A clean, soft cloth can be used for cleaning. Aggressive, abrasive cleaning agents that damage the surface must be avoided. The

device must not be subjected to hard knocks or vibration.

Commissioning

Prerequisites

• The transmitter and receiver must be installed and aligned correctly.

• The electrical connection must be established according to the connection diagram.

• The signal output must respond to object detection.

• If at least one light beam is interrupted, the output remains active as long as the object is detected.

Fault location

• Measure operating voltage

• Check the cabling.

• Check the transmitter and receiver for dirt and clean if necessary.

Function displays

Behind the optics cover on the connection side of the profiles there is a green Power ON operating indicator LED and a yellow

status display LED.

Resolution and beam clearance

The mechanical beam clearance determines the smallest detectable object size. Crossing the light beams increases the

resolution of the light grid.
