3.1 Symbols Relevant to Safety
3.2 ntended Use
The LGS automation light grid is a compact optical light grid that consists of a
emitter strip and a receiver strip. The detection field to be monitored is located
between the emitter strip and the receiver strip. The electronics for level
measurement are located in the receiver strip.
Areas of Use
■ Object detection in the packaging and material handling sectors
■ Detecting and counting irregular objects
■ Measuring and sorting objects of different heights (height control)
■ Presence and overhang control in material handling systems
■ Overhang control of load heights in transport systems and material
handling applications
■ Web sag monitoring
■ Position or shape monitoring
■ Gap detection
Always operate the device as described in these instructions to ensure that the
device and connected systems function correctly. The protection of operating
personnel and plant is only guaranteed if the device is operated in accordance
with its intended use.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and
plants, or result in their complete failure.
Caution!
Not a safety component
The light grid is not a certified safety light grid in accordance with EN 61496. t is
also not a safety component under the terms of the EU Machinery
Directive 2006/42/EC. The light grid must therefore not be used for the purpose of
preventing risk to individuals or parts of the body.

4 Product Description
4.1 Use and Application
LGS series: Touch it, save it—intelligent automation light grid with extras
Features
■ Adjustable beam crossover for refining the resolution. The beam crossover
does not alter the response time
■ Optical synchronization of both outer beams possible
■ Three separate outputs for height control
■ Light-on or dark-on options
■ Parameterizable object detection
■ Parameterizable beam suppression (blanking)
■ Operation via touch field or external input
■ O-Link interface for service and process data, and for parameterization
Description
n addition to the usual standard functions, LGS series light grids feature a range
of useful extra functions previously found only in much more expensive device
classes. These functions include ultra-quick object detection even with beam
crossover, the option of identifying objects, and remote communication via an O-
Link interface. The blanking function can be used to deactivate two connected
beam areas if unfavorable installation conditions result in plant components
extending into and interrupting the detection field. The standby operating mode is
another feature for applications where light grids are not in continuous operation.
The LGS is modular in design and available with five different beam gaps (8 mm,
17 mm, 25 mm, 50 mm, and 100 mm) and detection field heights ranging from
100 mm to 3200 mm to enable extensive monitoring of the evaluation area.
ntegrated signal evaluation means it is not necessary to mount a separate
additional switching device. The slimline profiles can easily be mounted using
existing holes, the rear continuous groove, or the fixtures available as
accessories, enabling light grids in the LGS series to be used to maximum effect
and tailored to the specific application.
The switching light grid has one switching output, which displays an identified
object, and three height control outputs.
The LGS receiver strip also has an O-Link interface, enabling advanced
parameterization, extensive configuration, identification, and diagnosis of the light
grid. This requires operation on an O-Link master.
The SC (stability control) diagnostic output indicates an insufficient functional
reserve, e.g., due to misalignment or soiling. The receiver strip can be taught in for
various objects via a teach-in input. The touch button can also be replicated
externally via this input.
