Caution!
Not a safety co mponent
The light grid is not a certified safety ligh t grid in accordance with EN 61496. It is
also not a safety com ponent under the terms of the EU Machiner y
Directive 2006 /42/EC. The ligh t grid must therefore not be used for the purpose o f
preventing r isk to individuals or parts of the bo dy.
Always operat e the device as desc ribed in th ese instructions to ensure that the
device and conn ected systems function correctly. The protection of operating
personnel and plant is only guaranteed if the device is operated in acco rdance
with its intended use.

4.1 Use and Application
LGS series: Tou ch it, save it—i ntelligent automation light grid with extras
Features
■
Adjustable b eam crossover for refining the resolution. The beam crossover
does no t alter the resp onse time
■
Optical synchronization o f both outer beams possible
■
Three separate o utputs for height control
■
Light-o n or dark- on op tions
■
Parameterizable object detection
■
Parameterizable bea m suppres sion (blanking )
■
Operation via touch field or extern al inp ut
■
IO-Link interface for ser vic e and process d ata, and for parameterization
Desc ript ion
In ad dition to the usual s tandard functions, LGS series light grids feature a range
of u seful extra functions previously found only in much more expensive dev ice
classes. These functions include ultra-quick ob ject detection even with beam
crossover, the option of identifying objects, and remote c ommunication via an IOLink interface. The blanking fun ction can be used to deactivate two connected
beam areas if unfavorable installation c onditions result in plant c omponents
exten ding into and interrupting the det ection field. The standby operating mode is
another feature for applications where light grids are n ot in con tinuou s op eration.
The LGS is modular in d esign and available with five different beam gaps (8 mm,
17 mm, 25 m m, 5 0 mm, and 100 mm) and detection field heights ranging from
100 mm to 3200 mm to enable extensive monitoring of the evalua tion a rea.
Integrated signa l evaluation means it is no t ne cessary to mo unt a sep arate
add itional switching device. The slimline profiles c an ea sily be mounted us ing
existing holes, the rear continuous groove, or the fixture s availab le as
accessories, enabling light grids in the LGS series to be used to maximum effect
and t ailored to the specific ap plication.
The switching light grid has one swit ching output, which displays an identified
object, and three height control outputs.
The LGS receiver strip also has an IO-Lin k interface, enabling advanced
parameter ization, extens ive configuration, identification, and diagnos is of the light
grid. This requires operation on an IO-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 b utton can also be replicated
externally via this input.

5.1 Preparation
Unpacking the Device
1. Check the p ackaging and con tents for d amage.
In the event of dam age, inform the shipping co mpany and notify the
supplier.
2. Check the p ackage contents against your order and the shipping do cuments
to ens ure that all items are presen t an d correct.
Should you have any q ues tions, direct them to Pepperl+Fuchs.
3. Retain the original pa ckaging in case the d evice is to b e stored o r shipped
again at a later date.
Note
Preven ting Extraneou s Light and Reflections
Situations in whic h the receiver is exposed to power ful extraneous light (e.g., from
flashing lamps or direct sunlight) must b e avoided. The influenc e of other optical
sens ors should also be prevent ed thro ugh s uitable positioning o r the use of
par titions. There must be n o reflective surfaces in the detection field, sinc e
reflections may prevent the detection of objects.
5.2 Mounting
Remember to kee p the detection field free of o bstac les wherever poss ible. The
first or last bea m in par ticular is used for visual synchron ization between the
emitter strip and the rece iver strip. If both synchronous beams are interrupted, the
detection field is no longer measured.

Installation
Figure 5.1 Light Grid Dimensio n Drawing
To mount the slim panels, use customized bore holes (d = 4.5 mm for M4 screws)
or a rear, continuous groove (for flat M6 nuts in accordance with ISO 4035).
Various fixtures are available for mounting the light grid see chapter 10.5.1.
Mounting Using the Rear Groove
There is a continuous g roove located on the r ear of the strip on the ligh t grid.
Standard flat M6 nuts in accordan ce with DIN 4 035 fit into this gro ove. Once these
nuts have been inse rted , they can b e use d to mou nt the light grid.
Mounting Using Holes D rilled by the Customer
The light grids can be mounted using user-defined holes. The ma ximu m screw
size is M4. Make sure you follow the instru ctions whe n po sitioning the hole.
Improper handling can damage the interna l electronics.
Drilling Holes
1. Mark the pos ition of the holes. Focus on the continuous line on the side of the
light grid .
2. Mark the p osition of the holes.
3. Using a 4.5 mm diam eter drill, drill all the way through the hous ing.
4. Deburr the hole.
5. Repeat the first steps until all ho les have been drilled.
6. Make sure that the aluminum chips do not scratch the optical surface.

Mounting
1. Align the em itter strip and rece iver s trip so the y are parallel with one another
and at the same height.
2. The strips must be aligned with one another with an accuracy of
approximately ± 5°.
3. During mounting , ensure that the two strips have the same orientation. (Cable
outlet facing eith er upward or downward on both strips.)
4. The maximum d etection range must not be exceeded.
