Device synchronization
The synchronization of receiver and transmitter for creating a functioning protective field is done optically,
i.e. without cables, via two specially coded synchronization beams. A cycle (i.e. a pass from the first to the
last beam) is called a scan. The length of a scan determines the length of the response time and affects the
calculation of the safety distance (see chapter 6.1.1 "Calculation of safety distanceS").
NOTICE
For the correct synchronization and function of the safety sensor, at least one of the two syn-
chronization beams must be free during synchronization and operation.

QR code
A QR code as well as the corresponding web address are located on the safety sensor.
At the web address, you will find device information and error messages (see chapter 11.3 "Error mes-
sages 7-segment display") after scanning the QR code with a mobile end device or after entering the web
address.
When using mobile end devices, mobile service charges can accrue.
