Possible causes Troubleshooting
WrnPlb (plausibil‐
ity warning)
Measured value briefly not plausible.
Light path between the measuring
device and the reflector briefly inter‐
rupted.
Observe the light spot on the reflec‐
tor. The light spot must not drift from
the reflector. If necessary, realign
the measuring device and reflector
or use a larger reflector. For align‐
ment and mounting see "Mounting",
page 18.
Measured value briefly not plausible.
Optical interference is present, e.g.
as a result of parallel mounted opti‐
cal sensors.
■
Remove any optical interference
see "Mounting", page 18.
WrnLsr (laser
warning)
The measurement laser is still ready
for operation but is at the end of its
service life.
Keep a replacement device ready for
use. It is advisable to replace the
device during the next maintenance
session.
WrnLvl (level warn‐
ing)
Current attenuation value is beyond
the error limit.
For recommended attenuation val‐
ues, see "Received signal level",
page 28.
■
Align the device and reflector with
each other, see "Aligning the dis‐
tance sensor and reflector with
each other", page 27.
■
Clean the optical interfaces like
the reflector and viewing window.
■
Check the reflective tape for dam‐
age.
WrnTmp (tempera‐
ture warning)
The internal device tempera‐
ture is outside the range of
–10 °C ... +75 °C.
For the permissible ambient temper‐
ature see "Ambient data", page 78.
■
Check the ambient temperature.
Provide better ventilation, if nec‐
essary.
■
Shield the device from radiated
heat, e.g. shade the measuring
device from direct sunlight.
■
At low ambient temperatures, use
a heating system for the device.
■
At high ambient temperatures,
use a cooling housing.
