13 Information for use

13.1 General

The information for use of the SRP/CS shall include all relevant instructions for the intended target
groups. The lifecycle phases of the machine where an SRP/CS is involved shall be covered by this
information.

13.2 Information for SRP/CS integration

The information which is important for the correct integration of SRP/CS shall be given to the integrator.

This shall include, but is not limited to the following:

a) limits (e.g. environmental conditions) appropriate information to ensure the continued justification
of the fault exclusions, e.g. regarding modification, maintenance and repair;

b) clear descriptions of the interfaces to the SRP/CS and protective devices;

c) response time;

d) operating limits (e.g. demand frequency);

e) indications and alarms;

f) muting and suspension of safety functions;

g) control modes and reset;

h) maintenance (see Clause 11);

i) maintenance check lists;

j) how to access and replace the parts of SRP/CS;

k) means for easy and safe trouble shooting;

l) test intervals where relevant;

m) mission time (e.g. ISO 13855:2010).

NOTE The integrator can be a manufacturer, assembler, engineering company or the user.
Specific information for each safety function on categories and performance level shall be provided (see
5.3), as follows:

— dated reference to this document (i.e. “ISO 13849-1:2022”);
— the categories of the subsystems forming the SRP/CS;
— the performance level, a, b, c, d or e;
— the PFH D value for SRP/CS, if relevant for subsystem(s).

13.3 Information for user

The information which is important for the correct use of SRP/CS shall be given to the user.

This can include, but is not limited to, the relevant aspects of 13.1 and 13.2. Also relevant information
with respect to testing of the safety functions shall be provided. The designer of the SRP/CS shall
provide information for use that describes the necessary maintenance tasks for the SRP/CS.

Information for maintenance can include tasks and applications, for example:

a) setting;
b) teaching/programming;
c) process /tool changeover;
d) cleaning;
e) preventive maintenance;
f) corrective maintenance;
g) troubleshooting/fault finding;
h) nature and frequency of inspections and safety functions;

i) instructions relating to maintenance operations which require technical knowledge and/
or particular skills and hence should be carried out exclusively by qualified personnel (e.g.
maintenance staff, specialists);

j) instructions relating to maintenance actions (e.g. replacement of parts) which do not require
specific skills and hence may be carried out by users (e.g. operators). It should be brought to
the attention of maintenance staff which parts are critical to safety and must only be replaced
with “like” parts or similar. In cases of non-identical parts being used to replace safety critical
components, a revalidation of the safety function will likely be required;

k) controlling hazardous energy (manual measures/other means) guidance, signs, and devices;

l) drawings/diagrams enabling maintenance personnel to perform their tasks (especially fault-
finding tasks to isolate conditions that caused the fault);

m) information about replacement of components at or before the T 10D period ends (see also C.4.2).

NOTE For additional information see ISO 20607:2019 and IEC 60204-1:2016, 17.2, f.

If any maintenance activity requires the modification of an SRP/CS this will then require a functional
test of the relevant safety functions
