devices.

The system designer must provide measures to ensure the safety of persons and sys‐

tems in accordance with the legal guidelines.

In the event of any other usage or modification to the MLG-2 measuring automation

light grid (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.

The module width is always 150 mm. The largest possible measurement field with of

3,150 mm results from the possible module number of 21. The smallest possible mea‐

surement field width is a measurement module with 150 mm.

NOTE

A maximum of 16 me

asurement modules can be used in one MLG-2 WebChecker. The

light grid can be filled with empty modules. A maximum of 19 empty modules may be

used and the total number of modules must not exceed 21.

There must be at least one measurement module on the connection side and on the

head side. If no empty modules are used, all active modules on the terminal compart‐

ment must be specified.

ts of sender optics, several sender elements (LEDs), and actuation

electronics. The receiver consists of receiver optics, several receiver elements (photodi‐

odes) and actuation electronics.

3.3.2 Measurement principle

Providing no object is located between the sender and receiver, the light beams from

the sender LEDs will hit the receiver LEDs.

If an object is located between the sender and receiver, the light beams will be inter‐

rupted, depending on the size of the object.

The MLG-2 works with the cross beam function. When the cross-beam function is

enabled, the light beam from a sender LED is received by three receiver LEDs in two

scans.

You get the most accurate measurement result when you place the material sheet or

sheets in the optimal object position. The optimal object position is the distance

between the sender and the object to be detected and is about 2/3 of the distance

between the sender and receiver, see figure 19, page 26. The light beams are distrib‐

uted uniformly at the optimal object position. The electronics in the receiver observe

the completely and partially interrupted light beams for evaluation. The exact object

position is determined energetically within a beam.

Scanning ranges

The oper

ating range is the distance between sender and receiver for which the MLG-2

works safely. The operating range is 2.5 m and takes into account an operating reserve.

Measurement field width

The MLG-2 consists of measurement modules and optionally empty modules. The mea‐

surement modules can be located on the connection side and on the head of the

MLG-2. Empty modules do not have LEDs.

The measurement field width is calculated from the ordered module number. Positions

9 to 11 represent the module number in the type code.

Beam separation and minimum object length

A minimum objec

t length is required so that an object is detected by the MLG-2.

t)

5 mm 4 mm

Additional minimum distances see "Req

uired minimum distances for an object",

page 28.

The minimum object length level depends on the following factors:

•

From the speed with which the object moves. The higher the speed, the longer the

object has to be.

•

The response time. The response time depends on the measurement field width.

The wider the measurement field width, the higher the scan time and the

response time.

3.5 Scan time

With the MLG-2, not all light beams are active at the same time. The light beams are

al

w

ays processed from the terminal compartment.

The scan time depends on the number of beams of the MLG-2. The higher the number

of beams, the higher the scan time.

The MLG-2 works with the cross beam function. When the cross-beam function is

enabled, the light beam from a sender LED is received by three receiver LEDs in two

scans.

rs

Figure 9: MLG-2 scan time, example of read direction of the connection side

The response times of the outputs result from the scan time.

T

he response time is the time it takes for an output to react following the detection of

an object. The typical response time is 3 × the scan time plus the transmission time to

the outputs. The optional Smoothing function can be used to multiply the response

time.

The data is transmitted in a cycle.

3.6 Operating reserve

The operating reserve defines the operational safety before contamination, vibrations,

mis

ali

gnment, temperature fluctuations, etc. cause the MLG-2 to produce incorrect

measurements.

The MLG-2 is subject to a certain level of contamination depending on its environment

and applica

tion. In principle, the MLG-2 must be cleaned regularly and a sensor teach-

in should be carried out after cleaning.

3.7 Minimum object attenuation

For the MLG-2 to detect the object, the object must dampen the energy of the light

beams eit

her completely or at least by 20%. An attenuation of 20% is achieved by mate‐

rials with a transmission of up to 80%.

If the MLG-2 is to detect partially transparent objects, in SOPAS ET, for the Sensitivity

parameter, you have to select the Medium or Fine option.

In materials with high transmission, the temperature difference between the operating

temperature and the temperature during teach-in must be less than ± 15 K.

The following prerequisites must be met:

•

The sender and receiver must be aligned precisely with one another.

•

The front screens from the sender and receiver must always be kept clean.
