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).

Safe functional blocks and
functions in SAFECONF
The safe functional blocks and functions available in the SAFECONF configuration software
for creating the safety logic are designed solely for use within the PSR-TRISAFE-S safety
module and support specific safety functions.
The safe functional blocks/functions can only perform their safety-related tasks within the
safe control system if they have been integrated into the execution process correctly and in
such a way as to avoid errors.
The area of responsibility of the block manufacturer in terms of the function of a safe
functional block or a safe function ends at the user interface, which is generated by the
inputs and outputs of the functional blocks/functions.
In order to fully execute a safety function, it is your responsibility to connect the inputs and
outputs of the safe functional blocks/functions in the SAFECONF configuration software:
– To your safety network
– To the single-channel or two-channel sensors and actuators connected to the inputs
and outputs of the safety module
In defining the safety integrity level or category for the overall safety function, you must take
into consideration all components involved in the execution of this safety function (sensors,
actuators, wiring, etc.).
WARNING: Only use the PSR-TRISAFE-S safety module according to the
information listed in this section.
You must observe all information in the online help for each functional block. Theoretical
examples of the use of the safe functional blocks are described in "Application examples".
WARNING: In order to use a safe functional block or a safe function according to
the required safety integrity as defined by DIN EN 61508, DIN EN ISO 13849 or
DIN EN 62061, you must take into consideration the entire path of the safety
function (safety module, device parameterization, wiring, sensors, actuators,
single-channel or two-channel operation, etc.) starting from the "functional block
I/O" interface.
Validate the entire path on completion.

2.1 Method of operation and structure of the
PSR-TRISAFE-S safety system
The overall system:
Hardware and software
The PSR-TRISAFE-S safety system consists of the following components:
– PSR-TRISAFE-S safety module
– SAFECONF configuration software
– Suitable safe control devices, sensors, and actuators (depending on the application)
The PSR-TRISAFE-S safety module is designed for monitoring and evaluating safety-
related control devices in machines and systems (see "Intended use" on page 1-7). The
safety module monitors safe control devices and safety sensors connected at its inputs,
evaluates the incoming signals according to its configuration, and controls the outputs
accordingly.
The SAFECONF configuration software is used to configure the PSR-TRISAFE-S safety
module and therefore provides the relevant editors as well as suitable startup and
diagnostic tools.
The diagram below illustrates the overall system in an application example.

Hardware:
PSR-TRISAFE-S
The PSR-TRISAFE-S safety module offers 20 digital safe inputs for connecting a maximum
of 20 single-channel or 10 two-channel safety-related sensors and control devices.
The PSR-TRISAFE-S has 4 digital safe outputs, which are semiconductor outputs
(24 V DC/2 A (total current)). The outputs are designed to meet up to category 4 according
to EN 954-1.
Depending on the configuration, stop category 0 according to DIN EN 60204-1 can be
achieved for each output (see "Stop category 0" on page 2-4).
In addition, four signaling current paths, two test pulses at two outputs each, and two ground
switching outputs are available.
For more detailed information about the safety module, please refer to the device
description in Section 3.
Software:
SAFECONF
The PSR-TRISAFE-S safety module can only be configured and parameterized using the
SAFECONF safe configuration software, which is executed on a separate Windows®PC.
The software offers a graphical connection editor for this purpose. The safety logic can be
created here by graphically connecting prepared safe functions and functional blocks to the
inputs and outputs of the safety module. The connections are made intuitively using the
mouse, and the editor prevents impermissible connections (e.g., between certain outputs).
In addition, the software provides a safe parameter editor, which can be used to configure
each input and output of the PSR-TRISAFE-S safety module.
A special online mode supports a detailed function test of the safety logic executed in the
PSR-TRISAFE-S safety module. Current signal values can be read from the
PSR-TRISAFE-S safety module, transmitted to the configuration software, and displayed
there "live" in the connection editor.
For more detailed information about the configuration software, please refer to the software
description in Section 4.
Secure communication Communication between the PSR-TRISAFE-S safety module and the configuration
software is via a USB interface.
A special security protocol enables secure data transmission via the USB interface.
There is communication between the two components in both directions:
–PC→safety module: The configuration data and device parameters are downloaded
from the configuration PC to the safety module. Configuration data refers to the
application logic, which was created using SAFECONF.
The configuration can also be downloaded using the plug-in IFS-CONFSTICK. Please
refer to "Downloading the configuration from SAFECONF" on page 5-4 and

Communication via the
PSR TBUS DIN rail
connector
The PSR-TRISAFE-S safety module is equipped with an interface for the PSR TBUS DIN
rail connector. The PSR DIN rail connector from Phoenix Contact can be used to connect
slave extension modules. Communication with these modules is then established
automatically via the connector on the PSR DIN rail connector. Safety-related cross-wiring
is not required (see also "Mounting the safety module" on page 3-13).

2.2 Using the system
The PSR-TRISAFE-S safety module configured with SAFECONF is designed for
monitoring and evaluating safety control devices and safety sensors in machines.
Machinery Directives and various standards and safety regulations require machine or
system manufacturers to meet a high standard of safety.
Safety circuits Safety control devices and safety sensors differ as follows:
Emergency stop control devices can only be detected in the event of dangerous operation
and thus operate in the background. Safety door switches or light grids, for example, are
often required for operational reasons and therefore regularly control the
connection/disconnection of the safety-related part of the machine.
The PSR-TRISAFE-S safety module can be configured flexibly. For the creation of the
safety logic, it has safe functional blocks, which are part of the system. The
PSR-TRISAFE-S can be used to implement various safety functions in different safety
circuits. Some of the most important options are:
– Emergency stop monitoring
– Safety door monitoring (with and without guard locking)
– Two-hand control devices (Types II and III)
– External device monitoring (feedback monitoring)
– Monitoring and checking electrosensitive protective equipment
– Mode selector switch (evaluation of a mode selector switch and an enable switch)
– Muting applications (light grid monitoring with parallel muting)
Stop category 0 Depending on the safety logic configured for the actual application, PSR-TRISAFE-S safety
module outputs can be used to stop machines/drives with stop category 0 according to
DIN EN 60204-1.
DIN EN 60204-1 defines stop category 0 as uncontrolled stopping by immediate removal of
power to a machine.
Whether a safe output meets stop category 0 depends on the safe functional blocks
connected in the safety logic: only if the module output is connected directly to the enable
output of a safe functional block, which executes stop category 0 at its output, can the
module output also meet this category.
Example The EmergencyStop functional block executes stop category 0 at its enable output. If this
block output is connected directly to a module output, the safety module also executes stop
category 0 at this output.
Figure 2-3 on page 2-7 shows an example of this type of connection.
Equipment on the
machine
The configuration and startup of the relevant safety circuit must be planned and verified
precisely. Different machines are subject to different requirements for the implementation of
a safety function.
The term "machine" is used here to represent any technical systems according to
Machinery Directive 2006/42/EC.
