Safety regulations
Safety assessment
Before using a device, a safety assessment in accordance with the Machinery Directive is
required.
The product as an individual component fulfils the functional safety requirements in accord-
ance with EN ISO 13849 and EN 62061. However, this does not guarantee the functional
safety of the overall plant/machine. To achieve the relevant safety level of the overall plant/
machine’s required safety functions, each safety function needs to be considered separ-
ately.
Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by persons who are competent to do so.
A competent person is a qualified and knowledgeable person who, because of their train-
ing, experience and current professional activity, has the specialist knowledge required. To
be able to inspect, assess and operate devices, systems and machines, the person has to
be informed of the state of the art and the applicable national, European and international
laws, directives and standards.
It is the company’s responsibility only to employ personnel who
}Are familiar with the basic regulations concerning health and safety / accident prevention,
}Have read and understood the information provided in the section entitled Safety
}Have a good knowledge of the generic and specialist standards applicable to the specific
application.
Warranty and liability
All claims to warranty and liability will be rendered invalid if
}The product was used contrary to the purpose for which it is intended,
}Damage can be attributed to not having followed the guidelines in the manual,
}Operating personnel are not suitably qualified,
}Any type of modification has been made (e.g. exchanging components on the PCB
boards, soldering work etc.).
Disposal
}In safety-related applications, please comply with the mission time TM in the safety-related
characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

For your safety
The unit meets all the necessary conditions for safe operation. However, please note the
following:
}Please make sure you shut down the supply voltage or open the input circuit (e.g. oper-
ate the E-STOP pushbutton) when performing maintenance work (e.g. when replacing
contactors), otherwise the unit might switch on unexpectedly in the case of a wiring error.
Unit features
}Outputs using semiconductor technology:
– 2 safety outputs
– 2 auxiliary outputs
– 1 test pulse output
}Connection options:
– E-STOP pushbuttons
– Safety gate limit switches
– Start button
– Proximity switch
– Safety sensors from the PSEN 2.x series or position switches with N/C / N/O combin-
ation
– Position switch with N/C / N/C combination
}To process signals from output signal switching devices (OSSDs) on light grids
}LED display for:
– Supply voltage
– Switch state of safety outputs
}One logic input to AND-connect several units
}Feedback loops for monitoring external contactors
Safety features
The relay meets the following safety requirements:
}The circuit is redundant with built-in self-monitoring.
}The safety device remains effective in the case of a component failure.
}The safety outputs are tested periodically using an off-test.

Function description
When supply voltage is applied and the set operating mode is detected (initialisation
phase), the "POWER" LED is lit. The unit is ready for operation when the feedback loops
are closed.
}Input circuit S12, S22 is closed (e.g. E-STOP pushbutton not operated):
– The LED "CH.1" is lit.
– There is a high signal at safety output 14, the unit is active.
}Input circuit S12, S22 is opened (e.g. E-STOP pushbutton operated):
– The LED "CH.1" goes out.
– There is a low signal at safety output 14.
Input circuit S32, S44 is AND-linked with input circuit S12, S22 and logic input S36. The
result of the logic operation can be viewed through safety output 24 and auxiliary output
Y32:
}Input circuit S12, S22 is closed (e.g. E-STOP pushbutton not operated)
and
}Input circuit S32 closed, S44 open (e.g. safety gate closed)
and
}(If the logic input is active) there is a valid signal at the logic input:
– The LED "CH.2" is lit.
– There is a high signal at safety output 24 and auxiliary output Y32. The unit is active.
If one of these conditions is not met, the signal at safety output 24 and auxiliary output Y32
is low.

Auxiliary output Y33 indicates the status of input circuit S32, S44. There is a high signal at
the auxiliary output if the input circuit S32 is closed and S44 is open (e.g. safety gate
closed).
Feedback loop
Before a safety output is switched on, a test is run to establish whether the contacts at
feedback loop inputs Y6 and Y7 are closed. If a contact is open, an error is detected and
LEDs CH.1 and CH.2 will flash alternately. It will not be possible to switch the unit back on
until the feedback loops are closed and the safety function has been reset.
The feedback loop contacts are also checked when the signal at the output changes from
high to low. After this signal change, the contacts at the feedback loop inputs must close
within 150 ms. If a contact is still open after 150 ms has elapsed, an error is detected and is
displayed as a flashing code 1,8 (see Faults - malfunctions [ 20]). It will not be possible
to switch the unit back on until the error has been rectified and the supply voltage has been
switched off and then on again.
Logic AND connection
The PNOZ e5.13p has a logic input S36 for logic connections between several units.
Operating modes
}Dual-channel operation: Redundant input circuit; earth faults in the input circuit and start
circuit are detected.
}Automatic start: Unit is active when at least input circuit S11, S12 has been closed.
}Monitored start: Unit is not active until the start button has been operated and then re-
leased.
}Increase in the number of available contacts by connecting contact expandsion modules
or external contactors/relays.
Selecting sensors
When selecting sensors, you must comply with the technical details of the input circuits on
the PNOZelog units.
