Safety
Intended use
Safety light grids of the PSEN opII4H Series are electrosensitive protective equipment of
the 4. They are used to protect personnel and systems. The safety light grids are designed
for
}
securing hazardous areas within buildings and
}
securing access within buildings with a resolution of 30 mm.
The safety light grid may only be used for personal protection on machinery if
}
the hazardous state can be removed by the safety light grid and
}
the starting of the machine is controlled by the safety light grid and
}
the safety assessment prescribes no better resolution than 30 mm.
The safety level PL e (Cat. 4 )/SIL CL 3 is only achieved if
}
the safety outputs use 2-channel processing.
The safety light grid is not equipped with a restart interlock.
If the safety assessment necessitates a restart interlock, this feature must be ensured
within the plant’s programmable safety system. The system may not be started in the haz-
ardous area following a protection violation if personnel are still in the hazardous area.
Prevent circumvention of the protected field. This means that other safety devices and safe-
guards may be required in addition to the safety light grid. These should be determined via
a safety assessment based on the specific application area and specific local conditions
(e.g. official specifications).
Refer to IEC/TS 62046 to determine other necessary safeguards for securing the hazard-
ous area.
Their application must fulfil the site’s relevant national regulations (e. g. EN 60204-1,
NFPA 79:17-7).
