1 The modular safety relay myPNOZ
myPNOZ is a modular safety relay, which can be used to implement various safety func-
tions without the need for programming. A safety function can be achieved through the
combination and wiring of the respective myPNOZ components. The “plug and play” prin-
ciple was in the foreground during development, without compromising on safety require-
ments. With myPNOZ it is easy to implement safety functions up to PL e of EN ISO 13849
and SIL CL 3 of EN 62061 and SIL 3 of IEC 61508.
You create your individual myPNOZ using the web application myPNOZ Creator. It’s a
simple process requiring no knowledge of programming. All you need to do is define the re-
quired safety functions and how they are linked.
Pilz then assembles your myPNOZ from the various modules, before setting it up and test-
ing it.
Your myPNOZ arrives “ready-to-install”. All you need to do is install it in the control cabinet
and wire it up. After testing the safety functions, myPNOZ is operational.

2Introduction to Getting Started manual
This Getting Started manual uses an example to describe how to create and commission a
myPNOZ. The Getting Started manual shows you the elementary steps and familiarises
you with the myPNOZ.
A detailed description of the myPNOZ and the individual modules can be found in the
myPNOZ System Description.
WARNING!
Loss of safety function due to incorrect use of the myPNOZ
This Getting Started manual does not contain the safety guidelines needed
for safe installation and operation.
You must read the myPNOZ System Description.

Task
Getting started Modular safety relay,myPNOZ
1005615-EN-02 | 6
3 Task
}A processing machine has two protection zones. One processing unit and a packaging
unit with inspection area.
}In an emergency it should be possible to stop the whole machine. It should be possible to
trigger the emergency stop from both units.
}Staff must be able to reach into the processing unit to change the tool or for cleaning
work.
It must be guaranteed that the processing unit is in a stop state whenever a staff member
reaches into the danger zone.
}Maintenance staff must be able to reach into the inspection area for maintenance work.
It must be guaranteed that the conveyor is stopped whenever a staff member reaches
into the danger zone.
}Only the unit on which work needs to be carried out should be stopped. The other unit
should continue running.
}After a stop, the units should only restart following confirmation on the operator panel.
}It must be guaranteed that nobody reaches into the product outlet area while the produc-
tion unit is running. However, products must be able to exit.

Safety functions

1005615-EN-02 | 7
4 Safety functions
Global E-STOP function
In an emergency, the whole machine (processing unit and conveyor) can be stopped from
both areas via the E-STOP pushbuttons (ES1 and ES2).
Monitored start with rising and falling edge
If the E-STOP function has been triggered, confirmation must be given on the operator
panel in order for the machine to restart.
Zone 1: Processing unit
The processing unit is secured using a safety gate and light curtain.
}Safety gate safety function (SG1)
If the safety gate is opened, then the processing unit is stopped.
The safety function is started with a monitored start with rising and falling edge. If the
safety function has been triggered, confirmation must be given on the operator panel in
order for the processing unit to restart.
}Light curtain safety function (LC)
If the light curtain is interrupted, then the processing unit is stopped.
The safety function of the light curtain is temporarily suspended through integrated L-mut-
ing, so that the products can exit the processing area without the processing unit being
stopped.
The safety function is started with a monitored start with rising and falling edge. If the
safety function has been triggered, confirmation must be given on the operator panel in
order for the processing unit to restart.
Zone 2: Packaging unit with inspection area
The inspection area is equipped with a hatch for maintenance work. The hatch is secured
using a safety switch.
}Safety gate safety function (SG2)
The conveyor is stopped via a safety switch as soon as the hatch is opened.
The safety function is started with a monitored start with rising and falling edge. If the
safety function has been triggered, confirmation must be given on the operator panel in
order for the conveyor to restart.

5 Configure myPNOZ with myPNOZ Creator
The safety functions and their logic connections are now mapped out in the myPNOZ Cre-
ator.
The web application myPNOZ Creator enables configuration to be carried out based on a
logic plan or through the combination of modules. Based on this system configuration, the
web application automatically assembles an individual myPNOZ.
It selects the required modules, defines the sequence and defines the position of the rotary
switches. The result is a pre-configured myPNOZ, which can be ordered directly.
5.1 Create logic configuration
Open the web application myPNOZ Creator (http://mypnoz.com/creator) and map out the
safety functions and their logic connections.
}Global E-STOP function
Each myPNOZ contains the global safety function. It affects the outputs in each zone and
is AND-linked to the inputs on the input modules. The global safety function is pre-con-
figured as an input in each zone; changes to the properties affect all zones.
So the global E-STOP function ES is only configured once for ES1 and ES2.
}Zone 1:
– Global E-STOP function
Monitored start with rising and falling edge
with test pulse evaluation for detection of shorts across contacts
– Safety gate input function (SG1),
Monitored start with rising and falling edge
with test pulse evaluation for detection of shorts across contacts
– Light curtain input function (LC),
Monitored start with rising and falling edge
– Relay output, instantaneous

}Zone 2:
– Global E-STOP function
Monitored start with rising and falling edge
with test pulse evaluation for detection of shorts across contacts
– Safety gate input function (SG2),
Monitored start with rising and falling edge
with test pulse evaluation for detection of shorts across contacts
– 2 semiconductor outputs, instantaneous
Simulate configuration
A simulation can then be started for test purposes, during which the potential interactions
can be simulated.
Click on an input in simulation view and the switching outputs will be highlighted.
