}EN ISO 13849-1: up to max. PL e
If multiple sensor interfaces PDP20F4mag are connected in series, 3 additional sensors
per sensor interface may be connected in series.
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 [ 13]).
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
environments, measures should be taken to comply with the applicable
standards and directives for the respective installation site with regard to in-
terference.
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
The unit meets all the necessary conditions for safe operation. However, please note the
following:
}Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a
rated insulation voltage of at least 250 V.

Function description
The inputs of the PDP20F4mag are AND-linked. The result of the logic AND operation is
expressed via safety outputs O0 and O1.
A signal output (SO) indicates the state of the sensors.
Safety outputs
}There is a high signal at safety outputs O0, O1 when all the input circuits I10 ... I41 are
closed.
}If at least one of the input circuits is open or a sensor is partially operated, the safety
outputs will switch to a low signal.
PDP20 F 4 mag
Operating Manual PDP20 F 4 mag
24737-EN-03 8
Signal Output
}There is a high signal at the signal output SO when the connected sensors are oper-
ated (N/O contact closed).
}If at least one of the sensors is not operated or is partially operated, the signal output
SO will switch to a low signal.
Detection of shorts across contacts
2 test pulse outputs T0 and T1 enable shorts across contacts to be detected at the inputs.
The two test pulse outputs are permanently assigned to the inputs. If the test pulses are
swapped or there is a short circuit at the inputs, the device switches off the safety outputs
safely (low signal) and registers an error.
Series connection
The safety outputs of a PDP20F4mag may be connected to the cascading inputs I40 - I41
on another PDP20 F 4 mag. 3 additional sensors may be AND-linked via this device. In the
event of a short across the contacts, the safety outputs will be switched off safely (low sig-
nal).
Input SI
The input SI is reserved for future functions and may not be used.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notch on the rear of the unit to attach it to a DIN rail (35mm).
}When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle)
}Push the device upwards or downwards before lifting it from the DIN rail.
Wiring
Please note:
}Information given in the "Technical details [ 13]" must be followed.
}Calculation of the max. cable length lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 13])
Rl/km = cable resistance/km
}Use copper wiring with a temperature stability of 75 °C.
}The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}1 wire may be connected per terminal. Use a terminal block if you need multiple con-
nections per terminal.
}Ensure the wiring and EMC requirements of IEC 60204-1 are met.
