1.4 Safety of the machine or system
Draw up and implement a
safety concept
In order to use the system described in this document with the associated safe functional
blocks, you must have drawn up an appropriate safety concept for your machine or system.
This includes a hazard and risk analysis, as well as a test report for validating the safety
functions.
The target safety integrity level (SIL according to DIN EN 61508 and category according to
DIN EN ISO 13849-1) is ascertained on the basis of the risk analysis.
The safety integrity level or category ascertained determines:
– How safe sensors, control devices, and actuators should be wired within the overall
safety function.
– How safe functional blocks should be used in the safety logic. (The safety logic is
created using the SAFECONF configuration software.)
Within the safe control system used, the safe functional blocks support the following safety
integrity requirements:
– Up to SIL 3 according to standard DIN EN 61508
– Up to SILCL 3 according to standard DIN EN 62061
– Up to category 4 according to standard DIN EN ISO 13849-1
Check hardware and
device parameterization
Please note that you must carry out a validation every time you make a safety-related
modification to your overall system. Use the relevant checklists when carrying out the
validation and also enter the details requested in the "Project Information" dialog box in the
SAFECONF safe configuration software.
Use your test report to ensure that:
– The safe sensors and actuators are connected correctly in the PSR-TRISAFE-S safety
application. To do this, use the "Wiring check" function in SAFECONF (see page 2-11).
– The parameterization of the inputs and outputs of the PSR-TRISAFE-S safety module
is correct.
– The signals have been connected to the safe sensors and actuators correctly (single-
channel or two-channel).
– Cross-circuit detection is implemented in your application, if required (see page 2-8).
– All safe functional blocks and functions in the SAFECONF configuration software are
connected correctly.
WARNING: Ensure the safety of the machine or system.
The operator bears sole responsibility for the safety of the machine or system. The
Machinery Directive must thus be observed.
Please note that you are responsible for implementing all additional requirements
resulting from applicable directives and legislation in order to meet the above safety
integrity requirements (see also "Directives and standards" on page 1-5).
