Possible error cause
Measure
PLB
(implausible measure
-
ment values)
Laser beam interruption
Laser spot must always be incident on the
reflector.
Laser spot outside of reflector
Traverse rate < 10m/s?
Measurement range for maximum distance
exceeded
Restrict traversing path or select AMS with
larger measurement range.
Velocity greater than 10m/s
Reduce velocity.
Ambient temperature far outside permissi
-
ble range (TMP display; PLB)
Select AMS with heating or ensure cooling.
ATT
(insufficient received
signal level)
Reflector soiled
Clean reflector or glass lens.
Glass lens of the AMS soiled
Performance reduction due to snow, rain,
fog, condensing vapor or heavily polluted
air (oil mist, dust)
Optimize usage conditions.
Laser spot only partially on reflector
Check alignment.
Protective film on reflector
Remove protective film from reflector.
TMP
(operating temperature
outside of specifica
-
tion)
Ambient temperatures outside specified
range
In case of low temperatures, remedy may
be an AMS with heating.
If temperatures are too high, provide cool
-
ing or change mounting location.
LSR
Laser diode warning
Laser diode prefailure message
Send in device at next possible opportunity
to have laser diode replaced. Have replace
-
ment device ready.
ERR
Hardware error
Indicates an uncorrectable error in the
hardware
Send in device for repair.
