3.2 Product characteristics
3.2.1 Product features
The MLS is a non-contact sensor used to determine the position of a magnetic line tape
or t
he posit
ion of up to three line tapes simultaneously; these tapes are primarily used
in conjunction with AGCs (autonomous guided carts).
The sensor is also capable of detecting defined markers positioned adjacent to the
actual line.
NOTE
Fr
om firmware version 5, an inertial measuring unit (IMU) is integrated as an additional
navigation aid which allows for detection of the current orientation of the sensor (see
"Inertial measuring unit", page 49).
Other new features of firmware version 5 are:
Bitmap, see "Bitmap", page 42
Track optimization, see "Track optimization", page 43
Temperature sensor, see "Temperature sensor", page 52
Event detection, see "Event detection", page 52
3.2.2 Operating principle
Principle of operation
T
he MLS de
termines the position of the magnetic tape via a row of hall sensors. The
raw data from the hall sensors is fed into an algorithm to calculate the position of the
line tape.

R
e
solution refers to the minimum position change of the magnetic tape relative to the
sensor that can be reflected in the sensor output.
Cycle time
The cycle time indicates the time interval within which the sensor can provide a new
output signal.
Repeatability
Repeatability refers to the change in output signal when the relative position of the
magnetic tape to the sensor does not change.
Orientation of the sensor
The orientation of the sensor indicates the tilt of the sensor around the gravity axis
(expressed with roll and pitch angle) as well as the rotation of the sensor around this
axis (expressed by the yaw angle).

5.3 Mounting of the magnetic tape
To navigate AGCs, the MLS is aligned to the Line Center Point of a magnetic tape, which
specif
ies the route of the AGC. The magnetic tape is stuck to the ground or embedded
in the ground. The criteria for selecting the suitable magnetic tape are described in
chapter 3.2.3. SICK offers respective self-adhesive magnetic tapes as accessories for
the MLS (see www.sick.com/MLS).
NOTE
The f
ollowing information is based on internal test results. However, this does not mean
that all users do not have to test the suitability of the magnetic tape for their intended
purposes.
5.3.1 Preparation
The SICK magnetic tape is well-suited for laying in the inner area. The following points
mus
t be ensur
ed before mounting the magnetic tape:
The surface must be fixed, flat and closed.
°
Moisture and contamination such as dirt, grease, dust, etc. must be removed
to make sure the magnetic tape will really hold. Use clean cloths and solvents
(e.g. benzine, acetone, pure alcohol) or floor cleaners with degreasing effect.
Make sure the substrate can tolerate any solvents used.
Any paint surfaces must adhere firmly, be free of solvents and silicone and be
completely dry.
After cleaning with solvents, let the substrate air out for about 10 minutes.
The ambient and surface temperature should be at least +15 °C; if applicable,
provide for supply of warm air before, during and after processing. This activates
the adhesive very well.
The route should be as free of ferromagnetic materials as possible.
A sample adhesion of the magnetic tape is recommended.
5.3.2 Laying
Before laying the magnetic tape, plan out the route on the ground in line with the layout.
Gaps should be a
voided, magnetic tape overlaps can be used in a targeted manner
(see intersections).
Remove about 10 cm of protective paper from the back of the magnetic tape.
Place the exposed end of the strip in the correct position and press down on it.
Use your hand to peel off the rest of the protective paper and rub the strip firmly
with your other hand. With a suitable pressure roller or a wood roller, press down
on the marking tape.
With wide strips, always roll from the center to the edge to roll out air pockets.
Curves
The magnetic tapes from SICK are suitable for laying curves with large radii. A minimum
curve radius of 1.5 m must be observed. For smaller curve radii, cut up the magnetic
tape and stick the pieces together so they are flush. When selecting the curve radius,
make sure that the “field of view” of the MLS on the AGC does not leave the route,
which causes detection to fail.

For
ks
To make forks, one track per side can be detected in addition to the main route. If the
diverters are stuck together so that the forked track comes directly out of the main
track, data output as improved track detection at diverters is recommended (can be
adjusted via index 0x2006, subindex 1, see "Process data objects", page 34).

Intersections
For t
rack intersections (the track tapes cross at a 90° angle), one track should be com‐
pletely glued over the other. Splitting a track band and attaching a bump to the through
track band is not recommended. This causes difficulties with track detection. If the sen‐
sor detects such a situation, however, it outputs the following process data:
#LCP = 7; LCP1 = LCP2 = LCP3

The MLS can detect and differentiate between both magnetic tape with north pole on
the t
op side (5337613) and south pole on the top side (5337614). To limit zones on a
route, it is therefore possible to change from one magnetic tape to the other in a tar‐
geted manner.
Markers
The MLS is capable of detecting magnetic codes using so-called markers next to the
main track. For a detailed description, see chapter chapter 8.6.
5.3.3 Protection
To protect the magnetic tape if there is a strong mechanical load, a protective tape or
pr
o
tective epoxy layer can be attached to the magnetic tape.
In general, rotating or turning vehicles on the magnetic tape, as well as moving objects
like pallets against the tape, should be avoided. If this cannot be avoided, lowering the
magnetic tape into the ground is recommended.

6 Electrical installation
6.1 Safety
6.1.1 Notes on the electrical installation
CAUTION
Dan
ger due to incorrect supply voltage!
An incorrect supply voltage may result in injuries from electric shocks and/or damage to
the device.
Only operate the sensor with safety extra-low voltage (SELV).
NOTICE
Sensor damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
Only carry out wiring work when the power is off.
Only connect and disconnect electrical connections when the power is off.
The e
lectrical installation must only be performed by electrically qualified person‐
nel.
Standard safety requirements must be met when working in electrical systems.
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
Wire cross-sections in the supply cable from the customer’s power system must be
designed in accordance with the applicable standards. When this is being done in
Germany, observe the following standards: DIN VDE 0100 (Part 430) and DIN VDE
0298 (Part 4) and/or DIN VDE 0891 (Part 1).
Circuits connected to the device must be designed as SELV circuits (SELV = Safety
Extra Low Voltage).
Protect the device with a separate fuse at the start of the supply circuit.
A shielded cable is not required in order to adhere to the electromagnetic compatibility
guideline
s specified by EN 61000-6-2/4. It is recommended, however, especially when
working with longer connecting cables.
The IP enclosure rating for the sensor is only achieved if the connected cable is com‐
pletely screwed in.

grouped into the following four groups according to their sensitivity to interference
or radiated emissions:

Group 1: C
ables very sensitive to interference, such as analog measuring
cables
°
Group 2: Cables sensitive to interference, such as sensor cables, communi‐
cation signals, bus signals
°
Group 3: Cables which are a source of interference, such as control cables
for inductive loads, motor brakes
°
Group 4: Cables which are powerful sources of interference, such as output
cables from frequency inverters, welding system power supplies, power
cables
b
Cables in groups 1, 2 and 3, 4 must be crossed at right angles, see figure 8.
b
Cables in groups 1, 2 and 3, 4 must be routed in different cable channels or
metallic separators must be used, see figure 9 and see figure 10. This
applies particularly where cables of devices with a high level of radiated emis‐
sion, such as frequency converters, are laid parallel to sensor cables.
