MAINTENANCE
9.5.4 Completing maintenance work at the measuring point
▸ If the SR-unit was equipped with a weatherproof cover, refit it again.
▸ Note work done, special observations, information for future maintenance work as well
as requirements for parts that need to be ordered in the Maintenance protocol.
9.6 Evaluation unit (EvU)
The evaluation unit is designed for maintenance-free operation over the entire service life
of the measuring system. If the evaluation unit is mounted outdoors, the following simple
checks should be carried out regularly due to the load resulting from changing weather
conditions:
• Visual inspection
– Is the enclosure undamaged and the fitting intact?
– Does the enclosure front door open and close easily?
– Is the enclosure window free from moisture?
– Does the illuminated LC display on the evaluation unit function correctly?
1 Open the evaluation unit door and check the following:
– Are the cable connections OK?
– Is the enclosure dry inside?
If the answer to any one of these questions in this Section (
page 112) is not “yes”:
▸ Clarify the cause.
▸ Carry out any repairs necessary.
If the evaluation unit is damaged (e.g. LC display failure):
▸ Contact SICK Service or the local sales representative.
WARNING: Risk of injury through exposed electrical connections
The electrical connections are exposed when the evaluation unit door is open.
▸ Observe the relevant safety regulations.
