safety output is in the OFF state.

Lights up green when at least one
safety output is in the ON state.

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.
9.3.2
Network LEDs
The device has different LEDs for every network interface. These network LEDs are
located below the display.
CAUTION
The network LEDs are only used for diagnostic purposes and are not safety-relevant.
The safety function of the device is not impaired even if the status indicators are
incorrectly displayed or fail.
