Error
Possible error cause
Measure
PWR LED "OFF"
No supply voltage connected
Check supply voltage.
Hardware error
Send in device.
PWR-LED "flashes red"
Light beam interruption
Check alignment.
Plausibility error
Traverse rate >10m/s.
PWR-LED "static red"
Hardware error
For error description, see display,
It may be necessary to send in the device.

General causes of errors
Display
Possible error cause
Measure
PLB
(implausible measurement
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 of the permissible
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, con-
densing vapor, or heavily polluted air (oil mist, dust)
Optimize usage conditions.
Laser spot only partially on the reflector
Check alignment.
Protective foil on the reflector
Remove protective foil from reflector.
TMP
(operating temperature out-
side of specification)
Ambient temperatures outside of the specified
range
In case of low temperatures, remedy may be an
AMS with heating.
If temperatures are too high, provide cooling 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 replacement device
ready.
ERR
Hardware error.
Indicates an uncorrectable error in the hardware
Send in device for repair.
