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.

Function description
The inputs of the PDP20F4mag 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 PDP20F4mag 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.

NOTICE
–No sensor should be connected between safety outputs O0 and O1
of the first PDP20F4mag and inputs I40 and I41 of the second
PDP20F4mag. With a series connection, only safety output O0/O1
may be connected to the cascading inputs I40 - I41.
– The signal output SO indicates the state of the connected sensors.
The state at input circuit I40 - I41 is not considered.
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.
When the supply voltage is applied, the device checks whether the device is operating as a
stand-alone device or in series with another PDP20F4mag.
The unit is ready for operation when the Power LED is permanently lit.
