Contents of this chapter
This chapter gives maintenance instructions for the safety function.
Maintenance
After the operation of the safety circuit has been tested at start-up, it does not need any
scheduled maintenance during its specified lifetime.
In addition to proof testing, it is a good practice to check the operation of the safety
function when other maintenance procedures are carried out on the machinery. Do the
acceptance test described in chapter
Start-up and acceptance test on page 45 .
If you change any wiring or component after the start-up, replace the FSO or FSE module,
modify FSO module parameters or restore parameters to their factory default values, you
must:
•
Use only ABB approved spare parts.
•
Register the change to the change log for the safety circuit.
•
Test the safety function again after the change. Obey the rules given in chapter Start-
up and acceptance test on page 45 .
•
Document the tests and store the report into the logbook of the machine.
