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.

Product Description

Operation indicator and status indicator on the receiver

The control panel on the receiver unit consists of 12 indicator elements. The two

outer two symbols act as control elements (touch buttons). The receiver unit can

be parametrized via menu selection on the control panel (see chapter 5.1).

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.
