Safety regulations
Safety assessment
Before using a device 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.

For your safety
DANGER!
Risk of malfunction of pacemakers or implanted defibrillators
The magnetic field of the safety switch may cause malfunctions of pace-
makers or implanted defibrillators.
People with a pacemaker or implanted defibrillators must maintain a dis-
tance of at least 100 mm to the safety switch and actuator.
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 [ 24].
– 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.

Feasibility monitoring for safety inputs S11 and S21
}If one safety input switches from high to low, while the other safety input remains high,
an unequal status is displayed: Input LED has quick yellow flashes and Device LED
flashes red
}If this safety input switches back from low to high, while the other safety input remains
high, a feasibility error is displayed and a partial operation lock is triggered: Input LED
flashes yellow and Device LED flashes red
A switch to a high signal will only lead to normal switch operation if both inputs had a low
signal. From this moment on, the switch to high may occur (partial operation lock see Error
display [ 28]).
}Diagnostic input Y1
If a fieldbus module of the SDD is used, the diagnostic input Y1 is automatically activ-
ated and data is read.
If no fieldbus module of the SDD is used, the diagnostic input Y1 is not used.
}Signal output/diagnostic output Y32
The status of the actuator is output. If a fieldbus module of the SDD is used, the signal
output/diagnostic output for the writing of data is activated.

Safety Device Diagnostics
Safety Device Diagnostics is an option that can be selected independently of the safety-re-
lated wiring.
When using the Safety Device Diagnostics, up to 16 sensors connected in series can be
connected as a subscriber to a fieldbus module.
The communication of the sensors with the fieldbus module is automatically built up again
with each new supply of the supply voltage. As a result, a sensor can be exchanged, e.g.
when servicing, without the need for special measures.
An exchange can be detected via the fieldbus module e.g. through the serial number.

PSEN cs6.11 M12/8
Operating Manual PSEN cs6.11 M12/8
1003424-EN-06 11
}With Safety Device Diagnostics there are the following diagnostic options for the field-
bus module:
– Poll information of the sensors (examples: what sensor in the series has switched,
at what point could there be an open circuit in the series connection)
– Read configuration parameters of the sensors (examples: Number of remaining
teach-in processes, serial number of the switch)
– Perform actions (example: poll updated actuator name)
The results of the sensor diagnostics can be checked already during the installation phase
via the display in the fieldbus module, without the need to connect the fieldbus module to
the network.
}With Safety Device Diagnostics there are the following diagnostic options for the field-
bus module for simple wiring:
– Information is passed on via the fieldbus module directly to the network
– Mappings of the signal outputs to the sensor are automated by the SDD.
This prevents wiring errors and an expansion or reduction of the sensors is possible
without the need to change existing wiring.
– Wiring in accordance with IP20: Rapid installation in the control cabined is enabled.
– Wiring in accordance with IP67: Various passive junctions can be used (see Order
references for accessories [ 35]) to connect several sensors with only one
cable from the field in the control cabinet.
Further information on Safety Device Diagnostics can be found in Additional documents
that apply [ 7].

Wiring
Please note:
}Information given in the Technical details [ 31] must be followed.
}The max. cable length lmax in the input circuit is calculated from
– the max. cable capacitance at the safety outputs (see Technical data [ 31]).
– the minimum permitted supply voltage at the sensor (19.2 V).
}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.
}When connecting in series, consider the requirements of manipulation protection and
the protection against bypassing or from overriding the safety switch (ENISO14119).
}When the safety inputs of the safety switch are controlled by an upstream device, and
they are not wired with 24V,
– They must be monitored for shorts across the contacts in dependence of the Per-
formance Level or SIL level to be achieved or
– The the faults at the safety inputs that can occur by shorts across contact will have
to be excluded by suitable measures (e.g. wiring in accordance with EN 602041).

Connection to evaluation devices
Make sure that the selected evaluation device has the following property:
}OSSD signals are evaluated through 2 channels with feasibility monitoring
Please note:
}Information given in the Technical details [ 31] must be followed.
}The use of Safety Device Diagnostics is described in the System Description "Safety
Device Diagnostics".
CAUTION!
Do not connect the signal output to 0 V!
If the signal output Y32 is connected to 0 V, the safety switch may be dam-
aged as a result. Connect the signal output Y32 to a consumer, e.g. to the
input on a control system, or leave the signal output unconnected. Also note
the max. current (see Technical details [ 31]).

Series connection
The safety sensors PSENcode are also suitable for series connection with other sensors.
The series connection of maximum 32 sensors PSENcs 5.x and PSENcs 6.x is approved
for SIL CL 3 without using the SDD.
When using the SDD, the series connection of maximum 16 sensors PSENcs 5.x and
PSENcs 6.x is approved
In practice, the maximum possible number will be limited by the following parameters,
among others:
}The required SIL level (e.g. SIL CL 3),
}the required performance level (e.g. PL e (Cat. 4)),
}the maximum delay or risk time permitted by the application.
Ensure there is sufficient supply voltage, taking inrush currents and fusing into considera-
tion.
CAUTION!
Extension of delay-on de-energisation
When several (n) devices are connected in series, the delay-on de-ener-
gisation time adds with the number of interconnected safety switches.
The max. delay-on de-energisation is made up of the
risk time (see Technical details [ 31])
+ (n-1) x max. delay-on de-energisation of the inputs
+ max. delay-on de-energisation of the evaluation device
}When making series connections using SDD, only use the following passive junctions.
– PSEN ix2 F4 code
– PSEN ix2 F8 code
– PSEN Y junction M8-M12/M12 PIGTAIL
– PSEN Y junction M12-M12/M12 PIGTAIL
– PSEN Y junction M12 SENSOR
