Drive control board boot

If you reboot the drive control board (either by cycling the power or with parameter
96.08 Control board boot), the FSO module goes into the Fail-safe mode. To exit the
Fail-safe mode, switch the power off and on, reboot the FSO module with drive
parameter 96.09 FSO reboot or press the Boot FSO button in Drive composer pro.
Note: The STO function must be completed before you can reboot the FSO module
with parameter 96.09 FSO reboot or the Boot FSO button (see section
off (STO) on page 57).

Updates

After any changes in the safety application or the safety system configuration, you
must perform the acceptance tests to verify that the safety functionality is maintained.
See chapter Verification and

Proof tests

If periodic proof testing is necessary based on the safety calculations, you must
include proof tests in the maintenance plan and perform them periodically. See also
section Proof test intervals during operation
Note: The person responsible for the design of the complete safety function should
also note the Recommendation of Use CNB/M/11.050 published by the European co-
ordination of Notified Bodies for Machinery concerning dual-channel safety-related
systems with electromechanical outputs:
• When the safety integrity requirement for the safety function is SIL 3 or PL e
(cat. 3 or 4), the proof test for the function must be performed at least every
month.
• When the safety integrity requirement for the safety function is SIL 2 (HFT = 1) or
PL d (cat. 3), the proof test for the function must be performed at least every 12
months.
This is a recommendation and depends on the required (not achieved) SIL/PL. The
FSO module does not contain any electromechanical components.
