Warning - laser prefailure message: 
LSR
Laser diode old, device still functional, exchange or have repaired.
Warning - temperature monitoring: 
TMP
Permissible internal device temperature exceeded / not met.
Plausibility error: 
PLB
Implausible measurement value. Possible causes: light beam interruption, outside
of measurement range, permissible internal device temperature considerably
exceeded or traverse rate >10m/s.
Depending on the configuration, either zero or the last valid measurement value is
output at the interfaces.
Warning received signal: 
ATT
Laser outlet window or reflector soiled or fogged by rain, water vapor or fog. Clean
or dry surfaces.
Internal hardware error:
ERR
The device must be sent in for inspection.
Bar graph
Indicates the strength of the received laser light.
The center bar represents the ATT warning threshold. The distance value remains
valid and is output at the interfaces.
If no bar graph is available, the PLB status information appears at the same time.
The measurement value has thus been assessed as being implausible. Depending
on the configuration, either zero or the last valid measurement value is output at the
interfaces.
Interface info
"LNK0" and "LNK1" in the display indicate an existing EtherNet connection for BUS IN and
BUS OUT. If the status info "LNK0" or "LNK1" is not displayed although the data line is
connected, the connection is faulty.

The connection status is additionally signaled by a green/orange multicolor LED below the
BUS IN and BUS OUT plug connector, see chapter "LINK LED for BUS IN and BUS OUT".
