Measures
Check cause for the reduced SIG-
NAL QUALITY:
• Device alignment.
• Clean optical window.
• Eliminate the possibility of envi-
ronmental influences such as
snow, rain, fog.
• Laser diode: at end of life ex-
pectancy
Check LSR LED (see chapter
8.1 "Error displays of the operat-
ing state LEDs").
Check ambient temperature
• Initiate measures for lowering
the ambient temperature.
Check supply voltage.
Check Ethernet cable connection.
