When first switching on the safety laser scanner, the start process can last up to
100 seconds. When switching on again, the required start time depends on the scope
of the configuration data. The start process then takes about 10 to 30 seconds.
When the start procedure is complete, the status LEDs and the display show the safety
laser scanner’s current operational status.

Setup with reset: Flashes if the
restart interlock has been triggered.
Configuration with automated restart
after a time: Lights up while the con‐
figured time to restart expires.
The OFF state and ON state LEDs can be found in multiple locations on the safety laser
scanner. 3 additional sets are arranged in pairs on the base of the optics cover. So the
LEDs can also be seen in many cases when it is not possible to see the display, e.g. due
to the mounting situation or because it is hidden from the operator’s position.
The device has different LEDs for every network interface. These network LEDs are
located below the display.

on the display:

Check during commissioning and modifications
The test is intended to ensure that the hazardous area is monitored by the protective
device and any attempted access to the hazardous area is prevented.
b
Carry out the checks specified in the test plan of the manufacturer of the machine
and the operating entity.
