Safety
Intended use
Safety light grids of the PSEN opII3F Series are electrosensitive protective equipment of
the 3. 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 14 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 14 mm.
The safety level PL d (Cat. 3 )/SIL CL 2 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 hazardous 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 safeguards 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 hazardous area.
Their application must fulfil the site’s relevant national regulations (e.g.EN60204-1,
NFPA79:17-7).
The following is deemed improper use in particular:
} Any component, technical or electrical modification to the product
} Use of the product outside the areas described in this manual
} Use of the product outside the technical details (see Technical details [ 42]).

Function description
Basic function
The safety light grid consists of a transmitter and a receiver.
Their shape and design
} protect the transmitter and receiver from external damage
} protect the safety light grid from malfunctions caused by vibration (see Technical de-
tails, environmental data section [ 42]).
The protected area is covered by infrared light beams, which are emitted from the transmitter to the receiver. The protected field thus produced is able to detect an opaque object.
The control and monitoring of the transmitted and received infrared rays is performed by
microprocessors.
The output signal switching devices (OSSDs) switch to the OFF state when one of the following conditions is met:
} one or more light beams are interrupted by an object, a body part, or an opaque object
that is at least as large as the resolution (14 mm) covered by the safety light grid,
} an error is detected by one of the OSSDs,
} or interfering light is detected.
If an error occurs, the OSSDs remain in the OFF state. The state can be returned to the ON
state only after a successful restart [ 38] of the safety light grid.
The safety light grid of the PSEN opII3F Series offers the following functions:
} automatic start
} automatic restart
} Operation of 2 safety light grids that are parallel to one another and are installed with
the same orientation (noting the information in ambient conditions [ 20] and min-
imum separation of parallel, aligned safety light grids [ 20])
Transmitters and receivers are each electrically connected with a cable with an M12 connector that is assigned to the transmitter and receiver on the LED side.
The transmitter and receiver are optically synchronised and therefore need not be directly
connected to each other.
Information about the operating status of the safety light grid and any error state is provided
by means of LEDs.
The indicators are described in the Status Information [ 35] section.
Automatic start and restart
Automatic start
During safety light grid commissioning, the safety light grid starts automatically, and the
OSSDs switch to the ON state under the following conditions:
} both OSSDs are wired correctly and
} no error has occurred and
} the protected field is clear.
If the protected field is violated, the OSSDs switch to the OFF state.

Automatic restart
The OSSDs automatically switch to the ON state during operation under the following conditions:
} both OSSDs are wired correctly and
} no error has occurred and
} the protected field is clear and
} at least 80 ms have elapsed since the switch to the OFF state.

Project configuration
Maintaining the safety distance
The minimum distance between the safety light grid and the hazardous machine component should be such that the operator cannot reach the hazardous area until the hazardous
machine part has come to a standstill.
In accordance with the standard
} ENISO13855
this distance depends on three factors:
} Response time of the safety light grid
Interval between interruption of the beams and the OSSD’s change to the OFF state
} Machine's stopping time
Interval between the change of the OSSD to the OFF state and the stopping of the hazardous machine movement (including the reaction time of the connected relay)
} Approach speed
The speed with which the object to be detected is nearing the hazardous area in mm/s
The general formula for calculating the minimum distance in accordance with
ENISO13855 is as follows:
S = K * (t1 + t2) + C
S Minimum distance in mm, measured from the start of the protected field to the
danger source
K Approach speed with which the object to be detected is nearing the hazardous area
in mm/s
K = 1600 mm/s when S > 500 mm
K = 2000 mm/s when S ≤ 500 mm
t1Response time of the safety light grid in seconds
Time it takes for the signal at the OSSD output on the safety light grid to change
once a protected field has been violated
t2Machine's stopping time in seconds
The time required for the machine to stop after the signal at the OSSD output
changes
C Additional distance of 0 mm for safety light grids with finger protection

Resolution
The safety light grids may only be used for protected fields in which a detection capability of
14 mm is sufficient.
Protected field perimeters
During planning, ensure sufficient protected field height to secure the hazardous area.
The protected field perimeter is defined in dimensions [ 40].
Ambient conditions
} Install the safety light grids in an environment that corresponds to the environmental
data provided in the Technical details [ 42].
} Do not install the safety light grid near particularly intense and/or flashing light sources;
this applies to the receiver in particular.
} The transmitter of one safety light grid must not interfere with the receiver of another
safety light grid.
} The transmitters and receivers of two different safety light grids must not be synchron-
ised.
} Avoid strong electromagnetic interference when operating the safety light grid.
} When operating the safety light grid, avoid the development of smoke, mist, or dust that
would reduce the grid’s operating range.

Distance from reflective surfaces
If there are reflective surfaces near the beams emitted from the safety light grid (whether
from above, below, or from the side), passive reflections can cause an object within the protected field to remain undetected (see diagrams).
This means that there must be a certain minimum distance between the safety light grid
and reflective surfaces.
