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 [ 13].
– 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: uniquely coded
}Dual-channel operation
}2 safety outputs

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.

PSEN cs2.2n
Operating Manual PSEN cs2.2n
1003367-EN-04 10
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 IEC 60204-1 are met.

Installation
CAUTION!
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material. Please check the oper-
ating distances and the assured release distance.
}The safety switch and actuator should be installed opposite each other in parallel.
– Make sure that the actuator is aligned to the marking on the sensor that guarantees
the operating distance required by the plant design (see Operating
distances [ 8]).
}Safety switches and actuators should be permanently secured using M5 safety screws
with a flat head (e.g. M5 cheese-head or pan head screws).
}Protect the actuator from contamination.
}Torque setting: Please note the information provided under Technical details [ 17].
}The distance between two safety switches must be maintained (see Technical
details [ 17]).
}Make sure that the safety switch and actuator cannot be used as an end stop.
}Please note the installation measures in accordance with EN ISO 14119 for a safety
switch design 4 and with level of coding High
}For simpler installation, the mounting brackets (see Order reference for
Accessories [ 21]) can be used.
}If using angled connector plugs, note the defined angle of the cable routing.
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.

Procedure:
Fig.: Sensing faces on the sensor
1. Drill holes (for M5 screws) in the mounting surface to secure the actuator and sensor
(see Dimensions in mm [ 17]).
2. Use a screw to fix the sensor to the mounting surface.
Make sure that the sensor marking that is be used for operation 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 printed side points towards the marking 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.
Adjustment
}The stated operating distances (see Technical details [ 17]) 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 [ 8]
and Lateral and vertical offset [ 9]).
Operation
NOTICE
The safety function should be checked after initial commissioning and each
time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.

PSEN cs2.2n
Operating Manual PSEN cs2.2n
1003367-EN-04 15
Check the function of the safety switch before commissioning.
Status indicators:
}"POWER/Fault" LED lights up green: The unit is ready for operation
}"Safety Gate" LED lights up yellow: Actuator is within the response range
}"Input" LED lights up yellow: Device is error-free
Fault indicator:
}"POWER/Fault" LED lights up red: Error message.
Flashing codes for fault diagnostics are output to the "Safety Gate" and "Input" LEDs
(see Error display through flashing codes).
Remedy: Rectify fault and interrupt power supply.
Error display through flashing codes
The "Safety Gate" and "Input" LEDs send flash signals; an error code can be established
from the number and sequence. The "Power/Fault" LED illuminates red.
Each error code is indicated by three short flashes of the "Input" or "Safety Gate" LED.
After a longer pause, the LED will then flash at one second intervals. The number of LED
flashes corresponds to a digit in the error code. The error code can consist of up to 3 digits.
The digits are separated by a longer period without flashing. The entire sequence is con-
stantly repeated.
Number of flashes 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Decimal error code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0
Example:
Error code 1,4,1:
Flash frequency of the "Safety Gate" or "Input" LED

II V
Meaning of flash frequency:
Flash frequency Meaning
I 3 times, short Code for error message
II Once, for one second each Code for 1st digit
III 4 times, for one second each Code for 2nd digit
IV Once, for one second each Code for 3rd digit
