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 spare actuators are used, these must be installed as described in
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.

}Information given in the Technical details [ 15] must be followed.
}Calculation of the max. cable length lmax in the input circuit:
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 IEC 60204-1 are met.
}In the following cases, check the function that detects shorts across contacts prior to
commissioning:
– On evaluation devices with DC supply voltage: Overall cable resistance ≥ 15 Ohms
per channel
– On evaluation devices with AC supply voltage: Overall cable resistance ≥ 25 Ohms
per channel

A full list of the certified Pilz evaluation devices (type examination certificate) is available in
the download area (http://www.pilz.com/support/downloads).
The correct connection to the respective evaluation device is described in the operating
manual for the evaluation device. Make sure that the connection is made in accordance
with the specifications in the operating manual for the selected evaluation device.
Defined properties of evaluation devices:
}2-channel with feasibility monitoring
}Open circuit monitoring of the safety switch is performed
}The inputs and outputs of the evaluation device must fulfil the requirements of
IEC61131

}Technical data of the evaluation device must fulfil the requirements in the Technical
details [ 15] of PSEN 2.2p-20
– Always comply with the max. switching current safety contacts of PSEN 2.2p-20.
}Outputs at the evaluation device must only be switched on again when both reed con-
tacts at the safety switch have been opened and closed (partial operation lock)
INFORMATION
Risk time in accordance with DIN EN 60947-5-3
The risk time is made up of the reaction time of the sensor (see Technical

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.
}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
The actuator should be protected from unauthorised removal and from con-
tamination.
}Prevent self-loosening of the fastening elements of safety switch and actuator.

PSEN 2.2p-20
Operating Manual PSEN 2.2p-20
20915-EN-08 13
}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
– Should be used for fixed wiring only
}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 pre-
vented.
}Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch design 4 and with level of coding 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.
}Install safety switch and actuator
– facing each other in parallel,
– so that both notches (see Lateral and vertical offset [ 9]) are exactly opposite
each other.
}If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected.
}Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws). Use screws made of non-magnetic mater-
ial (e.g. brass).
}A nib on the actuator prevents it twisting (see Dimensions [ 15]).
On the mounting surface, drill a hole (⌀ 2mm) as specified in the drawing, and place
the nib in the drill hole when installing the actuator.

}The protection type (see Technical details [ 15]) can only be achieved by using the
Pilz connection leads available as an accessory.
Adjustment
}The safety switch may only be used with the corresponding actuator PSEN 2.2-20.
}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
Installation [ 12]. Operating distances may deviate if other arrangements are used.
Note the maximum permitted lateral and vertical offset (see Operating distances and
Lateral and vertical offset [ 8]).
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.
