NoWrn No warnings –
wPlb Measured value not plausible.
Light path between measuring device and
reectorinterrupted.
Observelightspotonthereector.Thelight
spotmustnotmovefromthereector.If
required, re-align measuring device and
reectororusealargerreector.→ For
alignment and mounting, see page 27,
chapter 6.
Optical interferences • Remove optical interferences.
• Re-align distance measuring device and
reector.→ For alignment and mounting,
see page 27, chapter 6.
wLaser The measurement laser is still operational
but at the end of its service life.
Keep replacement device ready.
wLevel Current damping value is below the recom-
mended damping value. The recommended
damping value depends on the distance
betweenmeasuringdeviceandreector.
→ For recommended damping values, see
page 32, Table 4.
• Clean external lens surfaces like the
reectorandthelens
• Decrease the distance between the
measuringdeviceandthereector.
• Use a distance measuring device with a
higher range. → See page 126, chapter
14.2.
wTemp Internal device temperature is close to the
permissible range.
→ For the permissible ambient temperature,
see page 89, chapter 10.8.
• Check ambience temperature, improve
ventilation if applicable.
• Shield against radiation heat, e.g. share
the measuring device in case of direct
solar irradiation.
• Use device with heating at low ambient
temperatures.
• Use cooling housings for high ambient
temperatures.
