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.

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.

4 Test (In)
Connect the emitter strip after the top pinout. Insulate the unused wires. See the
switching example sho wn on the following pag e see Figure 5. 8 on page 19.
Range input
The transmitter strip has a range input (pin 2) that adapts the transmitting power to
the relevant sensing range in the application. The trans mitte r attains a maximum
sens ing range of 1.6 m (or 2 m with option /35) if the input is open. If the
app lication requ ires a longer sensing range (6 m or 8 m with /35), the input
mu st be connect ed either to + UB or 0 V. The reduction in the tran smitting
power also preven ts extrane ous light from interfering with other sensors located in
the direct vicinity.
Test input
The transmitter strip has a test input (pin 4) tha t can be used to test th e function of
all switching outputs on the system by activating the test input or operate the
system in energy-saving mode. The inp ut can be connected either to + UB or 0 V.

Function tes t: When the strip is activated for le ss than 1.2 s, the
transmitter beams switch off and the outputs on the receiver strip switch on
in the same way as when a beam is interrup ted. The outputs for the height
control can also b e tested in this way, if the relevant h eight control
parameters are available.
■
Energy-saving mode: If the test input is activated for longer tha n 1.2 s, the
system switches to ener gy-saving mode with minimal energy c onsumption
and no func tions. The light grid reverts back to normal mode immediately
when the test input is dea ctivated .

Conne ct the receiver strip after the top pinout. All ou tputs are s hort-circuit pro of.
Insulate the u nused wires. See the switch ing example shown on the followin g
page see Figur e 5.8 on page 19.
Stability C ontrol Output (SC)
The SC switching output indicates an insufficient functional reserve and makes
status indicator 3 flash at 4 Hz with a delay of 5 seconds. T he SC switching output
only switches off o nce there is sufficient functiona l reserve again, for example, if
the front lenses are cleaned or the strips are read juste d.
Switching Output (C /Q)
This signal output is active (switch ed o n for da rk on, opp osit e for light on) if an
object is within the detection ran ge, or if a t aught-in object is detected . This is
shown by status indicator 3 and 4 respectively.

Height Control Outputs (H1 , H2, H3)
These three indepen den t signal outputs are active if objects in the detection field
match the position of the taug ht-in heigh t controls see c hapter 7.1.2. The outputs
then report the same statuses as the function status indic ators 5 (H1), 6 (H2), and
7 (H3 ). If no height controls are parameterized, the sign al outputs are always
inactive.
Connecting External Operating Buttons (Teach-In Input)
The receiver strip is equipped with a teach-in input. This input can be us ed to
route out the two operating buttons and to connect them externally. The function
of the me nu bu tton is connected via an external normally-op en contact to + UB.
The OK b utton is connected via an external no rmally-op en contac t to 0 V. To
prevent a short circuit when both normally-open con tacts are actuated
simultaneously, a 1 k /2 W resistor must be installed b etween the NO con tact
and 0 V.
Parameterization can be locked to prevent the menu button being pressed
unintentionally (keybo ard lock). To do this, set the external teac h-in input
permanently to + UB.

Grou nding/Shielding
The system does not require grounding in stand ard cases. If EMC faults occur,
use a grounding cable with the cable lug supplied in the scope of delivery. The
groun ding/shielding must always be moun ted on the receiver str ip. This is purely
functional grou nding rather than pro tective grou nding. It acts solely as a down
conductor for cab le-related faults and is not subject to any safety guidelines (e.g.,
personnel protection ).
Ground/s hield the d evice as follows:
19
LGS Series
Installation
1. Make up a groundin g cable (max. 1 mm2) using the s upp lied cable lug.
2. Remove one housing sc rew from the cover at the cab le end, us ing a Torx T8

6.1 Final Assem bly
Checkin g the Mou nting an d Settings
1. Check the position of th e ligh t strips in relation to o ne anot her. The emitter
strip an d receive r strip must be a ligne d with one another with an accuracy
of approximately ± 5°.
2. The light strips ca n be opera ted briefly to che ck that the final asse mbly has
been performed correctly. The light strips are a ligne d perfectly with each
other when the yellow status LED on the receiver strip does not light up continuously or flash.
3. Now secure the light strips. Check all screw connections and tighten as necessary.
4. Check the cabling, referring to the wiring diagrams.
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.
The sign al needs t o be calibrat ed to ac hieve the bes t possible resolution for the
relevant application. Therefore, after a ny m odifications to the ap plication
(installation situation), s tart the system to recalibrate the signal and maintain the
sam e level of availability.
The sign al output respond s to detected objects, h eavy s oiling on t he lenses, or
misaligned profiles. The electronics compe nsate for s ignal changes caused by
grad ual soiling or temperature changes. If a minimum o f one light bea m is
inter rupted, the output rem ains active until the light bea m is interrupted (with dark
on) or soiling is detected.
6.2 Commissioning the Light Grid
Commissionin g
1. Check that the light grid is in the co rrect position.
2. Switch on the supply voltage. The operating status indicators on the emitter
strip a nd receiver strip light up green.
3. If the status LED is n ot lit, the light grid is aligned. The status L ED lights up
when the device is misaligned or an object is detected.
The two s trips are per fectly aligned with one another and can now b e
configured see chapter 7.1.
To commiss ion and operate the light grid via th e IO- Link inter face, please refer to
the following sec tion see chapter 7.2.

7.1 Operating the Light Grid
No objects o r he ight controls are p arameter ized on delivery.
The grid is o perated using the to uch field o n the front of the receiver strip. The
system can be parameterized as required using the two operating elemen ts and
the icons on the receiver strip. Parameterize the light grid by pres sing the menu
button. The "Q" ico n flashes in parame teriza tion mode.
■
Rapid flashing means: The function is not yet activated /taugh t in (the LED
turns on briefly a nd then turns o ff for a long period)
■
Slow flashing means: The function is activated/taught in (the LED tur ns on
for a long per iod and then turns o ff br iefly)
Pressing the menu button again activates a ll parameterizable func tion s in
succes sion, and each relevant icon flash es b rightly.
To teach in or activate the current pa rameter, press the OK button .

signal tracking ensures that the response threshold
remains constant. Reflective obje cts that are
occasionally present along the detection fiel d can
distor t signal tracking and caus e switchi ng faults. In
the wor st-case scenario, permanent detec tion is
signaled even though there is no object in the
monitoring fiel d. In this case, the function must be
disabled.
Signal tracking is inactive in the factory setti ng.
Enable func tion: Pressing the OK button enables
signal tracking.
When signal tracking is enabled, the specifi ed
resolution is r eached. The value of the switchi ng
threshold is set to 60 %.
Paramete rization via IO-Link
Parameterization via IO-Link allows the resp onse
threshold and signal track ing to be defi ned
independently of each other.
=> Without tracking: The response threshol d can
be selec ted in 10 % increments between
0 = m inimum thres hold, 1 = 10 %, and 9 = 90 %.

7.1.2 Monitoring the object height with height controls
The LGS switching light grid has been designe d e.g. to monitor the load heights of
pallets. An H switching outp ut is t herefore allocated for every load height. For
example, the up per edge of the sm alles t object is taugh t in as height control 1
(H1), the upp er edge of the middle object as height control 2 (H2) and the up per
edge of the largest object as h eight control 3 (H3). No height output will switch on
for any ob ject smaller than height control 1. Only output H1 will switch on for
objects larger than or equal to height control 1 b ut smaller than heigh t control 2.
Larger o bjects will trigger outputs H2 and H3 as well. The assignm ent of more
than one beam to a height control is only possible via IO-Link. Switching output Q
is activated every time an object is detected.
Possible app lication-specific setting s:
■
Deactivate be am crossover
■

field
■

The switching light grid ca n identify solid or pe rforated objects in the de tection
field from the interrupted light beams. Output Q is switched f or the entire t ime that
the objec t is in the d etection field.
The object ca n also be set to a floating or fixed location in the detection field. If a
fixed p osition is conf igured , output Q will only switch o n if the identified o bjec t is
exactly at this taught location. The invers e ob ject identification operating mo de is
intended to detect ho les, e. g., in plates. Either individual holes or contiguous hole
patterns can be detected. The position of the outer edg e of the plate in the
detection field is irrelevant.
