Fault indications of the components
8.1.1
Fault indication on the LMS4x21
Fig. 99: Status indicators on the LMS4x21
Fault indication
The
Status
LED does not light up.
Fault cause
Possible solution to the problem
Fuse is defective.
▸
Check the fuse block in the cabinet of the
SIM2000-2 Prime controller and replace the
defective fuse if necessary.
Fault indication
The
Status
LED lights up red.
The LiDAR sensor independently monitors beam generation and automatically shuts it
down in the event of irregularities. The scanner will no longer send any measured
values.
Fault cause
Remedy
•
Error during initialization or self-
test.
•
LMS4x21 is not in measuring
mode or is in measuring mode,
but errors have occurred.
▸
Check the voltage supply.
▸
Interrupt the voltage supply to the LMS4x21.
▸
Restore the voltage supply.
If the fault persists or occurs again after the
voltage supply has been restored:
▸
Check the device status using SOPAS
(see below).
▸
If errors are listed there, contact SICK Service.
