wPlb Measured value not plausible.
Light path between measuring device and
reflector interrupted.
Observe light spot on the reflector. The light
spot must not move off of the reflector;
realign measuring device and reflector if
required, or use larger reflector.
→
For alignment and mounting,
see page 23, chapter 6.
Optical interferences • Remove optical interferences.
• Re-align distance measuring device and
reflector.
→
For alignment and mounting,
see page 23, 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 reflector.
→
For recommended damping values, see
page 28, Table 4.
• Clean external lens surfaces like the
reflector and the lens
• Decrease the distance between the
measuring device and the reflector.
• Use a distance measuring device with a
higher range.
→
See page 82, chapter 14.2
wTemp Internal device temperature is close to the
permissible range.
→
For the permissible ambient temperature,
see page 85, chapter 14.9.
• 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.
