SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
SI P1 (CU): Shutdown path test required
NONE
NONE
The time set in p9659 for the forced checking procedure of the safety
shutdown paths has been exceeded. The safety shutdown paths must
be re--tested.
After the next time that the "STO" function is deselected, the message
is withdrawn and the monitoring time is reset.
Note:
-- This message does not result in a safety stop response.
-- The test must be performed within the specified maximum time
interval (p9659, maximum 9000 hours) in order to comply with the
specifications in the standard for detecting faults in time and the
conditions to calculate the failure rates of the safety functions
(PFH value).
Operation for longer than this maximum time period is permissible, if it
can be ensured that the forced checking procedure is performed before
persons, who are dependent on the safety functions correctly function-
ing, enter the hazardous area.

Select STO and then deselect again.

was selected.
-- Subsequent response of message C01706: "SI Motion CU: SAM/
SBR limit exceeded".
-- Subsequent response of message C01714 "SI Motion: Safety
limited speed exceeded".
-- Subsequent response of message C01701 "SI Motion: STOP B
