Safety regulations
Safety assessment
Before using a device 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 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 preven-
tion,
}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 spe-
cific 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.

For your safety
DANGER!
Risk of malfunction of pacemakers or implanted defibrillators
The magnetic field of the safety switch may cause malfunctions of pace-
makers or implanted defibrillators.
People with a pacemaker or implanted defibrillators must maintain a dis-
tance of at least 100 mm to the safety switch and actuator.
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 [ 16].
– 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.
Unit features
}Transponder technology for presence detection
}Pilz coding type: Coded

Wiring
Please note:
}Information given in the "Technical details" must be followed.
}The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
}The inputs and outputs of the safety switch must have a protective separation to
voltages over 60 VDC.
INFORMATION
Only use safety relays with a 24 VDC supply voltage. Safety relays with a
wide-range power supply or in AC device versions have internal potential
isolation and are not suitable as evaluation devices.
}The supply voltage to the safety switch must be protected with a 2 A to 4A quick-acting
fuse.
}Ensure the wiring and EMC requirements of EN 60204-1 are met.

Connection to evaluation devices
Make sure that the selected evaluation device has the following properties:
}2-channel with feasibility monitoring
}OSSD signals are evaluated
Single connection
CAUTION!
Do not connect the signal output to 0 V!
If the signal output Y32 is connected to 0 V, the safety switch may be dam-
aged as a result. Connect the signal output Y32 to a consumer, e.g. to the
input on a control system, or leave the signal output unconnected. Also note
the max. current (see Technical details [ 22]).

Teaching in the actuator
Any approved Pilz actuator is detected as soon as it is brought into the response range.
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.
}The safety switch and actuator should be installed opposite each other in parallel.
Make sure that the actuator is aligned to the square marking on the sensor (see Oper-
ating distances [ 9]).
}Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws).
}Torque setting: Please note the information provided under Technical details [ 22].
}The distance between two safety switches must be maintained (see Technical
details [ 22]).
The distance can be undershot in certain application cases (see diagrams).

}If using angled connector plugs, note the defined angle of the cable routing.
}When installing make sure you comply with the requirements of EN ISO 14119.
}Make sure that the safety switch and actuator cannot be used as an end stop.
}For simpler installation, the mounting brackets (see Order reference for
Accessories [ 26]) can be used.
}The actuator should be protected from unauthorised removal and from contamination.
Close the mounting holes using the seals provided (see diagrams). The use of seals
should be regarded as equivalent to using permanent fastenings in accordance with
Clause 7.2c of ENISO14119.

Procedure:
1. Drill holes (for M4 screws) in the mounting surface to secure the actuator and sensor
(see Dimensions in mm [ 20]).
2. Use a screw to fix the sensor to the mounting surface.
Make sure that the square marking on the sensor can be operated using the actuator
from the right side.
3. Do not fully tighten the second screw on the safety switch.
4. Use a screw to fix the actuator to the mounting surface.
Make sure that the actuator with the triangle marking points towards the triangle mark-
ing on the sensor.
5. Do not fully tighten the second screw on the actuator.
6. Align the safety switch and tighten the screws.
7. Align the actuator and tighten the screws.
Use in operating heights higher than 2000 m above sea level
When using the PSEN cs5.11n note the reduced max. ambient temperature of +60 °C at a
height of 2000m to 4000 m.
Adjustment
}The stated operating distances (see Technical details [ 22]) only apply when the
safety switch and actuator are installed facing each other in parallel. Operating dis-
tances may deviate if other arrangements are used.
}Note the maximum permitted lateral and vertical offset (see Operating distances [ 9]
and Lateral and vertical offset [ 11]).
