INFORMATION
This gives advice on applications and provides information on special fea-
tures.
Safety
Intended use
The safety function of the safety switch is:
}Safe detection of the magnetic actuator within the response range
The safety switch meets the requirements in accordance with:
}EN 60947-5-3: PDDB only in connection
– with the operator PSEN ma1.4-03 or operator PSEN ma1.4-10
– the interface PSEN ix1 and
– the suitable evaluation devices (see Requirements and connection to evaluation
devices [ 10]).

erated with the following components:
}Actuator PSEN ma1.4-03 or actuator PSEN ma1.4-10 ,
}interface PSEN ix1 (see Order reference [ 21]) and
}an approved evaluation device.
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the product
}Use of the product outside the areas described in this manual
}Use of the product outside the technical details (see Technical details [ 19]).
NOTICE
EMC-compliant electrical installation
The product is designed for use in an industrial environment. The product
may cause interference if installed in other environments. If installed in other

Safety regulations
Safety assessment
Before using a unit 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 this description under "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.
}When decommissioning, please comply with local regulations regarding the disposal of
electronic devices (e.g. Electrical and Electronic Equipment Act).

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.
Unit features
}The actuator PSEN ma1.4-03 or PSEN ma1.4-10 belongs to the safety switch.
}Coded actuator
}Safety switch with cable (5 m)
}2 safety contacts (reed contacts - N/O)
}Different operating distances depending on the actuator see Technical details [ 19]
}Design:
– Safety switch with square design
– Actuator with square design: PSEN ma1.4-03
– Actuator with square design: PSEN ma1.4-10
}Operation Magnetic
}Switching voltage 24 VDC
}Series connection via PSEN ix1 interface
Function description
If the actuator is within the response range (safety gate closed), the safety contacts of the
safety switch are closed.
The safety switch is designed for applications in series connections.
Operate the PSEN ma1.4a-52 in conjunction with the following components:
}Actuator PSEN ma1.4-03 or actuator PSEN ma1.4-10 (see Order reference [ 21]),
}interface PSEN ix1 (see Order reference [ 21]) and
}a connected evaluation device (see Requirements and connection to evaluation
devices [ 10]).

Wiring
Please note:
}Information given in the Technical details [ 19] must be followed.
}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 [ 19])
Rl/km = Cable resistance/km of the cable (seetechnical details cable)
}Ensure the wiring and EMC requirements of EN 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
– For details of how to perform the test for shorts across the contacts, please refer to
the operating manual for the relevant evaluation device.
