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.).

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 [ 14].
– 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.

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.

Teaching in the actuator
Teaching in the actuator for the first time:
The first actuator PSEN cs4.1 detected by the safety switch is automatically taught in as
soon as it is brought into the response range.
To teach in a new actuator:
A maximum of 8 learning procedures are possible.
1. The actuator that is to be taught in must be brought into the safety switch's response
range as the only transponder. As soon as the actuator is detected, the "Safety Gate"
LED will flash yellow.
2. After 20 s has elapsed, the "Safety Gate" LED turns to quick yellow flashes. Trigger a
system reset in the next 120 s by interrupting the power supply.
3. When the supply voltage is switched back on, the learning procedure is complete and
the number of permitted additional learning procedures is reduced by 1.
NOTICE
– The actuator must not be removed during the learning procedure.
– It is no loner possible to reteach his actuator on the same safety
switch.
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.
}Actuator PSEN cs4.1: Safety switches and actuators should only be secured using M4
screws with a flat head (e.g. M4 cheese-head or pan head screws).
The actuator should be protected from unauthorised removal and from contamination.
Close the mounting holes using the seals provided. The use of seals should be re-
garded as equivalent to using permanent fastenings in accordance with Clause 7.2c of
ENISO14119.
}Actuator PSEN cs2.1: 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).
}Torque setting: Please note the information provided under Technical details [ 22].
}The distance between two safety switches must be maintained (see Technical
details [ 22]).
}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 [ 27]) can be used.
}Please note the permitted bending radii for the cable (see Technical details [ 22]),
to avoid excessive force on the individual strands.
}Make sure that the bend protection is not damaged. Such damage can cause the whole
product to fail.
Procedure:
Please note:
Installation is identical for all combinations of safety switch and approved actuators. The
diagram of the actuators PSEN cs4.1 and PSEN cs2.1 represents the other approved actu-
ators.
Safety switches PSEN cs4.1 with actuator PSEN cs4.1
1. Drill holes in the mounting surface to secure the actuator and safety switch (see Dimen-
sions in mm [ 20]).
2. Use two screws to fix the safety switch in place. Do not fully tighten the 2nd screw on
the safety switch.
3. Attach the screws for the actuator, leaving a distance of 3 … 6 mm between the screw
head and plate.
4. Slide the actuator on to the screws. The arrows on the labelled surfaces of the safety
switch and actuator must face each other. Align the actuator and tighten the screws.

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 [ 10]).

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.
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: There is a high signal at both inputs
Error display through periodic flashing:
}"Input" LED lights up yellow: the signal switches from high to low at one input, while a
high signal remains on the other input (partial operation).
Remedy: Open both channels of the input circuit.
}"Power/Fault" LED lights up red: Error message
Flashing codes for fault diagnostics are output to the "Safety Gate" or "Input" LED (see
Error display through flashing codes).
Remedy: Rectify fault and interrupt power supply.
Please note the different times for
}The switch-on delay after UB is applied
}The recovery time of the sensor and evaluation device.
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
