6.6 Aligndistancemeasuringdeviceandreectoragainst each other
1. Movethedistancemeasuringdeviceandreectorclosetogether.
2. Align the distance measuring device so that the light spot of the sensor
hitsthecenterofthereector.
3. Increase the distance between the distance measuring device and the
reector.Thesensorlightspotmustcontinuetohitthecenterofthe
reector.
4. Check damping. The damping value must not exceed the value in the
table.
Damping value Thetablebelowspeciesthesignalattenuationvaluesinrelationtothe
distancebetweenthedistancemeasuringdeviceandthereector.The
values in the “Typical signal attenuation” column represent the expected
values when the measuring path and the distance measuring device are
in perfect working order. If the signal attenuation value exceeds the value
in the “Maximum signal attenuation” column, check the condition of the
measuring path.
The distance measuring device issues a level warning if the signal attenu-
ation value reaches the critical value of approximately –96 dB. If the signal
attenuation value then continues to rise, a level and plausibility error are
output, along with the measured value “0”.
