Repair
Repair is by replacement of systems parts only. New parts must have the same part number
as the parts being replaced. Any variances must be agreed with Renishaw. The new system
must be installed and commissioned in accordance with the
'Commissioning test'
on page 13.
It is advisable that, in the event of failure, the affected parts should be returned to Renishaw
for further analysis prior to any replacement parts being sent. Using damaged parts invalidates
Functional Safety certification.
Proof testing
It is the responsibility of the system manufacturer to define any proof testing of the system.
Due to the diagnostic coverage (DC) and safe failure fraction (SFF) required to achieve SIL2,
the encoder can only support continuous demand use.
