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.
Table 10.1:
General causes of errors
Error
Possible error cause
Measure
BUS LED "OFF"
No supply voltage connected to the device
Check supply voltage.
TCP communication deactivated
Activate TCP communication.
BUS-LED "flashes green"
Address assignment via DHCP activated, but no IP
address assigned In this case, the device with the
permanently set address goes on the network
Assign IP address.
BUS LED "static red"
TCP communication is activated, but NO connection
to another participant
Sporadic
network error
Check wiring for proper contacting
Check wiring,
• In particular, check wire shielding.
• Check wires used.
EMC coupling
• Observe contact quality of screwed or soldered
contacts in the wiring.
• Avoid EMC coupling caused by power cables laid
parallel to device lines.
• Separate laying of power and data communica-
tions cables.
Network expansion exceeded
Check max. network expansion as a function of the
max. cable lengths.

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.
