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
sc
anner. 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.
More information about what the LEDs mean and the symbols and information shown
on the display: see "Troubleshooting", page 149.
