Contents of this chapter
This chapter contains information for the maintenance and decommissioning of the safety
function.
Safety circuit maintenance
After the operation of the safety function is tested at start-up, the safety function must be
maintained by:
• periodic proof testing
• replacing main contactor or breaker before the end of its specified lifetime.
See the contactor/breaker data sheet or manual.
It is also a good practice to check the operation of the safety function when other maintenance
routines are carried out on the machinery. Include this check in the routine maintenance
program of the machinery that the drive runs.
If you change any wiring or component after the start-up, or restore parameters to their
factory default values:
• Use only ABB-approved spare parts.
• Register the change to the change log for the safety circuit.
• If parameters were restored to the factory default values: Set the parameters related to
the safety function.
• Test the safety function again after the change. Do the start-up and acceptance test of
the safety function.
• Document the tests and store the report into the logbook of the machine.
