Safety regulations
Safety assessment
Before using a unit it is necessary to perform a safety assessment in accordance with the
Machinery Directive.
Functional safety is guaranteed for the product as a single component. However, this does
not guarantee the functional safety of the overall plant/machine. In order to achieve the re-
quired safety level for the overall plant/machine, define the safety requirements for the
plant/machine and then define how these must be implemented from a technical and organ-
isational standpoint.
Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is someone who, because of their training, experience and current pro-
fessional activity, has the specialist knowledge required to test, assess and operate the
work equipment, devices, systems, plant and machinery in accordance with the general
standards and guidelines for safety technology.
It is the company’s responsibility only to employ personnel who:
}Are familiar with the basic regulations concerning health and safety / accident preven-
tion
}Have read and understood the information provided in this description under "Safety"
}And 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-re-
lated characteristic data.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

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: Contact at S12 closed and contact at S24 open (e.g. safety gate closed)
– There are high signals at safety outputs 14 and 24 and auxiliary output Y32.
– LEDs "CH.1" and "CH.2" are lit.
}Input circuit: Contact at S12 open and contact at S24 closed (e.g. safety gate open)
– There are low signals at safety output 14 and auxiliary output Y32.
– LED "CH.1" goes out.
– There is a low signal at safety output 24 once the set delay time has elapsed.
– LED "CH.2" goes out.
Safety output 14 can also be delayed (see Logic input S35 and S36 [ 16]).
NOTICE
There is a low signal at the delayed safety output, at the latest after the set
delay time + 40 ms + 10 % of the set value, even in the case of a compon-
ent failure.
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 – Interference [ 22]). 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.
AND/OR connection
The PNOZ e3vp has two logic inputs S35 (OR) and S36 (AND) for logic connections
between several units.

Operating modes
}Dual-channel operation: Earth faults in the input circuit and shorts between the input cir-
cuit contacts will be detected.
}Automatic start: Unit becomes active once the contact at S12 has been closed and the
contact at S24 has been opened in the input circuit.
}Monitored start: Unit is not active until the start button has been operated and then re-
leased.
}The start-up test prevents automatic restarting after a power failure and subsequent re-
turn of voltage. The unit checks whether safety gates that are closed have been opened
and then closed again when supply voltage is applied.
}Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.
Installation
CAUTION!
Electrostatic discharge can damage components on the safety system!
Ensure against discharge before touching the safety system, e.g. by touch-
ing an earthed, conductive surface or by wearing an earthed armband.
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notch on the rear of the unit to attach it to a DIN rail.
}Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an end angle).
NOTICE
If you are connecting several units logically, please note the guidelines in
the section entitled Logic connection between several units [ 15].
