Reflector communication No connection between
sender/receiver unit and
reflector
●
Connection line not connected
or not connected correctly
●
Defective connection line
●
Defective reflector/scattered
light receiver
●
RS485 interface of the sender
unit defective
▸
Check the connection line

Contact SICK Customer
Service.
LED monitor overflow Overmodulation of the
monitor channel during
scaling
Incorrect alignment of the opti-
cal axes of sender/receiver unit
and reflector
▸
Check/correct alignment.
▸
Repeat scaling

Service.
Set reference Scaling not possible Measurement or monitor signal
too low (contamination, incorrect
alignment)
▸
Check/correct alignment.
▸
Clean the optical surfaces
( see “Maintenance on the
sender/receiver unit and
reflector/scattered light
receiver”, page 94 ).
Contamination Contamination value is
higher than the permit-
ted limit value ( see
“Technical Data”,
page 111 )
●
Deposits on the optical inter-
faces
●
Unclean purge air
▸
Clean the optical surfaces
( see “Maintenance on the
sender/receiver unit and
reflector/scattered light
receiver”, page 94 ).
▸
Check purge air filter ( see
“Cleaning the optical inter-
faces on the reflector”,
page 98 ).
