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.).

For your safety
WARNING!
Loss of safety function due to manipulation of the interlocking device
Manipulation of the interlocking device may lead to serious injury and death.
– You should prevent any possibility of the interlocking device being
manipulated through the use of a spare actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If substitute actuators are used, these must be installed as described
under Installation [ 12].
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.
}Do not remove the connector's protective cap until you are just about to connect the unit.
This will prevent potential contamination.

}Calculation of the max. cable length lmax:
Rlmax - Ri
Rl / km
Imax =
Rlmax = Max. overall cable resistance (see evaluation device's technical details)
Ri = Internal resistance sensor (see Technical details [ 15])
Rl/km = Cable resistance/km of the cable (seetechnical details cable)
}Ensure the wiring and EMC requirements of EN 60204-1 are met.
}Depending on which evaluation device is used, the overall cable resistance must be
checked; before commissioning it may also be necessary to check the cross circuit detec-
tion function.
}Protect the safety switch's electrical connections from corrosion.
}The safety contacts are not short circuit-proof.
}UL requirement: the supply voltage must be provided via a Class 2 power supply.

Installation
CAUTION!
Potential loss of safety function due to changed device properties
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material.
– Please check the operating distances and the assured release dis-
tance.
CAUTION!
Possible loss of the safety function by changing the release distance
Sar with non-flush installation
Installing the safety switch non-flush within electrically or magnetically con-
ductive material, the value for the assured release distance Sar can change.
– Check the assured release distance Sar.
}Safety switches and actuators must be positioned so that they are secured against a
change of position.
}Secure the actuator using a countersunk screw M4 or M5.
}The safety switch and actuator should only be secured using screws and nuts made of
non-magnetic material (e.g. brass or stainless steel).
}Avoid the risk of damages from foreseeable external influences by attaching the safety
switch and actuator. If necessary, safety switch and actuator have to be protected.

INFORMATION
Protect the actuator from unauthorised removal (e.g. via a screw lock or
concealed installation) and from contamination.
}Prevent self-loosening of the fastening elements of safety switch and actuator.
}The fastening of safety switch and actuator has to be sufficiently stable to ensure the
proper operation of the safety switch and the actuator.
}The distance between two safety switches must be maintained (see Technical
details [ 15]).
}Safety switches and actuators
– Should be kept away from iron swarf
– Should not be exposed to strong magnetic fields
}Prevent the safety switch and actuator being exposed to heavy shock or vibration.
}Make sure that the safety switch and actuator cannot be used as an end stop.
}Circumvention of the safety switch in a reasonably foreseeable manner must be preven-
ted.
}Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch type 4 with coding level Low.
}Alignment errors of the guard must not adversely affect the safety function of the guard.
}The assured operating distance Sao and the assured release distance Sar must be tested
under real conditions.
}Do not apply any installation tools (e.g. Pliers) on the surfaces of the switch.
}Install safety switch and actuator
– facing each other in parallel
– so that the faces with the product names are opposite each other.
}The protection type (see Technical details [ 15]) can only be achieved by using the
Pilz connection leads available as an accessory.
}If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected. In this case, use the spacer (see
Order reference [ 18]).
Adjustment
}The safety switch may only be used with the corresponding actuator PSEN 2.1-20.
}Always test the function with the PSENi1 interface and connected evaluation device.
}The stated operating distances (see Technical details [ 15]) only apply when the
safety switch and actuator are installed according to the specifications in
Installation [ 12]. Operating distances may deviate if other arrangements are used.
Note the maximum permitted lateral and vertical offset (see Operating distances and Lat-
eral and vertical offset [ 8]).

PSEN 2.1p-20

1004287-EN-04 | 14
Periodic test
}Carry out a monthly function test on the safety switch and actuator.
}Always test the function with the PSENi1 interface and connected evaluation device.
}The safety function may only be checked by qualified personnel.
