3 Safety
3.1 Intended use
The safety gate system is used for guard locking and interlocking swing gates and revolving
gates.
It meets the requirements in accordance with:
}EN 60947-5-3
}EN ISO 14119
}EN 62061: SIL CL 3
}EN ISO 13849-1: Up to PL e (Cat. 4)
The safety level PL e (Cat. 4)/SIL CL 3 can be achieved when
}The safety outputs use 2-channel processing and
}The solenoid is operated 2-channel via safe relay outputs, suitable for PL e (Cat. 4)/SIL
CL 3 applications.
Wiring errors should be excluded using appropriate measures. The potential solutions
are the protected cable layout or the use of pulsed semiconductor outputs.
3.2 Safety regulations
3.2.1 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.
3.2.2 Use of qualified personnel
The products may only be assembled, installed, programmed, commissioned, operated,
maintained and decommissioned by competent persons.
A competent person is someone who, because of their training, experience and current pro-
fessional activity, has the specialist knowledge required to test, assess and operate the
work equipment, devices, systems, plant and machinery in accordance with the general
standards and guidelines for safety technology.
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"
}And have a good knowledge of the generic and specialist standards applicable to the
specific application.

3.2.3 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.).
3.2.4 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).
3.3 For your safety
WARNING!
Potential loss of safety function during adjustment and repair work!
When carrying out adjustment and repair work, make sure that the power
supply of the plant is switched off and protected against switching on again.
WARNING!
Loss of safety function due to manipulative use of substitute actuating ele-
ments!
When substitute actuating elements are used, these have to be installed as
described in chapter Initial installation of safety switch [ 31]. When sub-
stitute actuating elements are used in a manipulative way to defeat the pro-
tective device, operating the plant presents a threat to life.
The operator has to consider this in the hazard analysis and he must de-
termine possible countermeasures.
Function description
Operating Manual PSEN sg2c
1003267-EN-04 10
4 Function description
The interlocking and guard locking system prevents the safety gates to the danger zone
from opening while the hazardous machine is switched on.
There is a high signal (safety gate closed and locked) at safety outputs X1-3 and X1-4 if the
following conditions are met simultaneously:
}Inputs X2-3 and X2-4 are high and
}The bolt tongue is within the response range and
}The guard locking element is engaged in the bolt tongue and
}The escape or auxiliary release pin is in the correct position.
Signal output X1-9 is high if:
}The bolt tongue is within the response rang
There is a low signal (safety gate open and hazardous machine function interlocked) at
safety outputs X1-3 and X1-4 if the following occurs:
}Inputs X2-3 or X2-4 are low or
}The guard locking element is outside the bolt tongue or
}The escape or auxiliary release has been operated or
}The guard locking element is not engaged in the bolt tongue.
If the safety outputs have been shut down by either of the inputs X2-3 or X2-4, they cannot
be switched back on until both inputs are low simultaneously.
To operate the solenoid, a high signal must be present at X1-6 (X2-6) and at X1-7 (X2-7)
after the hazardous movement has been ended.
4.1 Normal /Unlock mode
Normal mode:
The safety gate to the danger zone is not unlocked until the hazardous machine is stopped
and the pushbutton for access request has been operated.
}The guard locking element is disengaged from the bolt tongue as soon as there is a
high signal at terminals X1-6 and X1-7 or X2-6 and X2-7, followed by operation of the
pushbutton for access request.
Unlock mode:
The safety gate to the danger zone is unlocked when the hazardous machine is stopped.
This enables easier access for cleaning staff once the shift has ended, for example.
}The guard locking element is disengaged from the bolt tongue as soon as there is a
high signal at terminals X1-6 and X1-7 or X2-6 and X2-7.
