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.

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
