Code alignment
In the grid navigation application, the position of the vehicle is determined in relation to
the code. This convention (code coordinate system) is preset in the factory setting for
the GLS100, see table 2

codes.

Code data: Number of the MultiCode label
Using the SICK MultiCode label is recommended as it is optimally tailored to the appli‐
cation. The SICK MultiCode label also enables the highest overspeeds to be reached.
Alternatively, single 2D codes or 2D MultiCodes in QR (single code only) or Data Matrix
(MultiCode) formats provided by the customer can be used. QR single codes must
correspond to the 21x21, 25x25, 29x29, 33x33 or formats. The maximum edge length
must not exceed 38 mm. The 2D codes must have a minimum size of 1 mm (code
module size). The type of code to be read out can be selected under the “operating
mode” setting. DM MultiCodes are selected in the factory setting.
When using customer codes, the module size may have to be configured (ModBus: Reg‐
ister 151/152. CANopen Index 0x02002 Sub 02). Factory setting for the module size is
1.0 mm. If the module size is configured incorrectly, the sensor cannot determine the
z-position correctly.

5.1.1 Mounting requirements
■
Typical space requirement for sensor, see "", page 42.
■
Comply with technical parameters such as the permitted ambient conditions for
the operation of the sensor (e.g., temperature range, EM interference), see "Ambi‐
ent data", page 43.
■
Protect the sensor from direct sunlight.
■
Only affix the sensor using accessories supplied for this purpose -> there are no
screw connections on the sensor.
■
Sensing distance: 100 mm (±30 mm)
The sensing distance is the distance from the front sensor edge (housing edge) to
the ground.
5.1.2 Scope of delivery
The following are included with delivery of the sensor:
•
GLS100 grid localization sensor
•
1 quick-start guide
Accessories:
Accessories (e.g., cables, fastening adapters) are only included with delivery if ordered
separately.
5.2
Mounting the sensor
Arrangement over guide track
The GLS100 must be positioned orthogonally to the 2D code to be detected.
To achieve the maximum overspeed, the sensor should be positioned perpendicular to
the direction of travel.

6 Electrical installation
6.1 Safety
6.1.1 Notes on electrical installation
CAUTION
Danger 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/protective extra-low voltage (SELV/PELV).
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 electrical installation must only be performed by electrically qualified person‐
nel.
■
Standard safety requirements must be observed when working on 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 user’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).
■
Electrical circuits connected to the device must be configured as SELV circuits
(SELV = safety extra-low voltage/PELV = protective extra-low voltage).
■
Protect the device with a separate fuse at the start of the supply circuit.
The IP enclosure rating for the sensor is only achieved if the connected cable is
completely screwed in.
