NoWrn No warning –
wPlb Measured value not plausible.
Light path between the measuring device
andthereectorinterrupted.
Observethelightspotonthereector.The
lightspotmustnotdriftfromthereector.
If necessary, realign the measuring device
andreectororusealargerreector.→ For
alignment and mounting, see Page 26,
Chapter 6.
Optical interference • Remove any optical interference.
• Realignthemeasuringdeviceandreec-
tor. → For alignment and mounting, see
Page 26, Chapter 6.
wLaser The measurement laser is still ready for op-
eration but is at the end of its service life.
Keep a replacement device ready for use.
wLevel The current attenuation value is below the
recommended attenuation value. The recom-
mended attenuation value depends on the
distance between the measuring device and
thereector.→ For recommended attenua-
tion values, see Page 32, Table 6.
• Cleantheopticalinterfaceslikethereec-
tor and the lens.
• Reduce the distance between the measur-
ingdeviceandthereector.
• Use a distance measuring device with a
larger scanning range. → See Page 120,
Chapter 16
wTemp The internal temperature of the device is ap-
proaching the limit of the permissible range.
→ For the permissible ambient temperature,
see Page 119, Chapter 15.8.
• Check the ambient temperature. Provide
better ventilation if necessary.
• Shield the device from radiated heat, e.g.,
shade the measuring device from direct
sunlight.
• At low ambient temperatures, use a heat-
ing system for the device.
• At high ambient temperatures, use a
cooling housing.
