Original document
This document is an original document of SICK AG.
These instructions are only valid in connection with the 8016616 operating
instructions. You can find the operating instructions at www.sick.com.
The 8016616 operating instructions describe how to commission the MLG-2 light
grid.
These instructions supplement the specific requirements for commissioning with
the AFB box with CAN interface.
Connection, mounting, and configuration may only be performed by trained spe‐
cialists.
Not a safety component in accordance with the EU Machinery Directive.
Do not install the sensor in places exposed to direct sunlight or other weather
conditions unless this is expressly permitted in the operating instructions.
1 Product description
1.1 Intended use
The MLG-2 modular light grid is solely intended for the optical and non-contact
detection of objects, animals, and persons.
In the event of any other usage or modification to the MLG-2 (e.g., due to opening
the housing during mounting and electrical installation) or in the event of changes
made to the SICK software, any claims against SICK AG under the warranty will be
rendered void.

Function
The MLG-2 is an optical light grid consisting of a sender and a receiver. The light
beams from the sender elements encounter the receiver elements and form a
detection area. If an object is located between the sender and receiver elements,
the light beams will be blocked, depending on the size of the object (see graphic
of MLG-2 design).
The detection area is determined by the detection height and the sensing range
of the light grid. The monitoring height is determined by the necessary beam
separation and the number of beams. The sensing range of the light grid is the
distance between sender and receiver.

When setting the CAN offset via pin 18 CAN offset on the 19-pin male connector,
the current CAN offset is displayed on the 7-segment display.
2 Mounting
MLG-2
Mount the sender and receiver at the same height. The end with the cable
connection must point in the same direction for both devices.
When mounting, make sure that sender and receiver are aligned correctly. The
optical lens systems of the sender and the receiver must be located opposite one
another.
