Introduction
1 Introduction
1.1 Purpose of These Brief Instructions
These brief instructions contains basic instructions for operating the device. How-
ever, the manual takes priority over the brief instructions.
1.2 Product documentation on the internet
You can view all the relevant documentation and additional information on your
product at http://www.pepperl-fuchs.com. Simply enter the product name or
model number in the Product/Key word search box and click Search.
Select your product from the list of search results. Click on the information you
require in the product information list, e.g., Technical documents.
A list of all available documents is displayed.
1.3 Intended Use
The measuring LGM light grid consists of an emitter and receiver strip. Located
between the strips is the measuring range consisting of infrared light beams.
When an object enters the measurement field, one of several selectable measur-
ing methods sends out data on the interrupted beams via I/O-Link. The reading is
in mm.
Application areas
■Warehousing and material handling, packaging industry
Always operate the device as described in these instructions to ensure that the
device and connected systems function correctly. The protection of operating per-
sonnel and plant is guaranteed only if the device is operated in accordance with
its intended use.
The device and its input and output circuits must be operated from a power supply
that fulfills the requirements of P LV/S LV systems.
Only use recommended original accessories.
The operating company bears responsibility for observing locally applicable
safety regulations.
Caution!
Not a safety component
The light grid is not a certified safety light grid in accordance with N 61496. It is
also not a safety component under the terms of the U Machinery
Directive 2006/42/ C. The light grid must therefore not be used for the purpose of
preventing risk to individuals or parts of the body.

Introduction
Installation and commissioning of all devices may be performed only by trained
and qualified personnel.
It is dangerous for the user to make changes and/or repairs. Additionally, doing so
voids the warranty and excludes the manufacturer from any liability. In the event of
any serious errors, stop using the device. Secure the device against unintended
operation. To have the device repaired, return it to your local Pepperl+Fuchs rep-
resentative or your sales center.
Note
Repairs
If the light grid requires repair, please send the emitter and receiver together to
Pepperl+Fuchs.

Installation
3 Installation
3.1 Mounting
Make sure the detection field is free from obstacles. The first and last beams
within the detection field are used for optical synchronization of emitter and
receiver units. If both beams are blocked, synchronization is lost and the mea-
surement is inhibited. The system is preconfigured for operation wth cable outlet
upwards. For installation with cable outlet downwards, the receiver unit can be
configured via IO-Link for the zero-point reference on the cable side.
Figure 3.1 Light Grid Dimension 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 brackets are available for mounting the light grid .
Mounting Using the Rear Groove
There is a continuous groove located on the rear of the strip on the light grid. Stan-
dard flat M6 nuts (in accordance with DIN 4035) fit into this groove. You can mount
the light grid using these inserted nuts.
Mounting Using Customized Bore Holes
You can mount the light grid using user-defined holes. The maximum screw size is
M4. Make sure to follow the instructions when positioning the hole. Improper han-
dling can damage internal electronics.
