S In the case of a series commissioning of safety or when replacing a part, the
following applies:
-- The Safety password remains on the memory card
-- A Safety password is not required if a part is replaced
S Changing the password for the drives
-- p0010 = 95 commissioning mode (refer to Chapter 4.7 "Commissioning the

proceed as follows:
1. Restore the factory setting of the complete drive unit (Control Unit with all
connected drives/components).
2. Recommission the drive unit and drives
3. Recommission Safety Integrated
Or contact your regional Siemens office and ask for the password to be deleted
(complete drive project must be made available).

Forced checking procedure

Forced checking procedure and test of the shutdown paths
The forced checking procedure of the shutdown paths is used to detect software/
hardware faults at both monitoring channels in time and is automated by means of
activation/deactivation of the "Safe Torque Off" function.
To fulfill the requirements of ISO 13849--1:2006 regarding timely error detection,
the two switch--off signal paths must be tested at least once within a defined time
to ensure that they are functioning properly. This must be realized using the ma-
nual or process--automated trigger of the forced checking procedure.
