3.2 Function
The linear measurement sensor is a device that can measure product travel paths
up to 10km without moving parts. The device with its visible, red LED light beam
orientates itself by means of a barcode tape attached along the product travel path. By
reading the barcode, the device determines the absolute position and delivers this via
an interface.

Figure 1: Functionality schematic diagram
Determining bar code tape alignment
On startup, the device initially detects the alignment in relation to the barcode tape (0°
or 180°). The device automatically adapts itself to the alignment that is detected, and
starts outputting position values.
If there are no barcodes in the field of view when the device is started up, the device
selects the orientation which it detected before being deactivated. The device starts
position value output as soon as barcodes with the expected orientation are located in
the field of view.
3 FUNCTION AND USE
12 O P E R A T I N G I N S T R U C T I O N S | OLM100 8014310/1KE8/2023-07-06 | SICK
Subject to change without notice

Error F4 and the measured value "0" are output if an unexpected alignment is detected,
and this also applies if the alignment is changed during the product travel path. In
such a case, position values are not output until after the supply voltage has been
interrupted and the new alignment has been detected successfully (if the "Detect tape
position during operation" function has not been activated via SOPASET).
NOTE
In the delivery condition, the tape position is assumed to be 0°, i.e. the alignment of
the device and the barcode tape to each other is such that the lower edge of the device
(black part of the housing) and the lower edge of the barcode tape are directly opposite
each other.
During running operation, the alignment of the bar code tape can also be altered using
SOPAS ET see "Configuration and servicing with SOPAS Engineering Tool (SOPAS ET)",
page 28 or by configuration marks see "Configuration marks", page 14.
NOTE
If the barcode tape is mounted in the entire system with an alignment of 180° in
relation to the device, then it is necessary to make sure that the barcode tape is
located in the field of view when the device is started for the first time.
Error condition
If the device detects an error condition during the traversing (e.g. no barcode tape, or
barcode tape defective), this is immediately suppressed and extrapolated measured
values are output. The extrapolation time depends on the measured value history and
in the delivery condition is max. 160ms.
The measured value "0" is output if the error status is present for longer or exists from
the moment of switching on. Individual faulty bar codes do not have any effect on the
measured value.
Error statuses can be interrogated via the data interface. Alternatively, the SOPAS
ET software is also available for this in conjunction with the Ethernet configuration
interface.
3.3 Type label
There is a type label on the device that provides all relevant information.

The print resolution must be at least 1200dpi (pixels per inch). Page or size adjustment
must be deactivated.
3.5.1 Control marks
NOTE
For devices with an SSI interface, no control marks can be used due to the interface.
The purpose of control marks is to trigger a certain action in the device:
■Output of the control mark value at the data interface
Control marks can be stuck onto the barcode tape at selected points (e.g. switches).
When doing this, make sure that the cut markings of the fiducial are congruent with the
cut markings of the position mark that has been stuck over.
NOTE
In order to obtain a continuous distance value, it is necessary to ensure that there is a
position mark directly before and after a control mark. A maximum of one control mark
is permitted in the field of view of the device. Therefore, at least two position marks
must lie between two control marks.
Output of the value via the data interface
The information on a control mark consists of a letter (A, B, C, D or Z) followed by two
digits (0 - 9). All other control codes are output via the data interface as ASCII hex
values. The control code must be interpreted byte-by-byte as ASCII characters. In this
case, the most recently read control code is always output every cycle.
3.5.2 Configuration marks
Configuration marks are special barcodes with which parameters in the device can be
adjusted. After reading the configuration marks, the change is stored permanently in
the device.

To change a parameter, the appropriate configuration mark is placed in the field of
view of the device. The device confirms reading a configuration mark with both LEDs on
the upper part of the side of the housing (Power and Status). The responses have the
following meanings:
Signal Meaning
Both LEDs flash green Parameter has been changed.
Both LEDs flash orange Parameter was already set and remains
unchanged.

5 Mounting
5.1 Mounting procedure
1. Applying barcode tape see "Attaching the barcode tape", page 17.
2. Mounting the device see "Mounting the device", page 22.
3. Establishing electrical connection, see "Electrical installation", page 25.
5.2 General data on the bar code tape
The barcode tapes have a nominal length of 20m; they are supplied rolled up with
the smallest number on the outside. The particular measuring ranges are selected so
that successive barcode tapes can be placed against one another without gaps. The
sequential roll number is located on the barcode tapes to make it easier to maintain
the correct sequence.
Irrespective of the starting code required, bar code tapes with a customer specific
measuring range always begin with the sequential roll number "1".

5.3 Attaching the barcode tape
The orientation of the barcode tape in relation to the device must remain the same
throughout the entire product travel path (alignment always 0° or always 180° in
relation to the device).
For the best adhesion, the temperature of the surface and the barcode tape must be
between 15 and 25°C at the time of application.
Align the barcode tape with a reference edge (e.g. rail) of the product travel path and
stick this onto the smooth, dry surface that is free from grease and dust, without any
tension, folds or creases. The surface must be free of grease, dust and other soiling.
Small expansion joints and minor points of unevenness can be stuck over. At disruptive
points which would cause the barcode tape to be significantly distorted were it to be
stuck over, it is possible to cut out an individual barcode at the corresponding cut
marks.

To ensure optimum linearity, the distance between the two cut marks at the resulting
gap must be 30mm. At least two contiguous barcodes must follow after a gap. Contin‐
uous output of position values by the device is ensured if the width of the gap is not
more than 30mm and the barcodes were separated cleanly at the cut mark.
It is recommended that the self-adhesive, cut-to-length blank labels should be stuck
over the gap in order to allow it to be traversed without problems see "Blank labels for
repair codes or control marks", page 53.

A sequence of barcode tapes with discontinuous measuring ranges is not allowed,
otherwise a continuous position cannot be indicated. Where there is non-continuity (e.g.
at diverters), the device outputs a corresponding jump in the position value as soon as
at least two sequential barcodes of the new measuring range have been identified.
The device cannot output negative position values. Therefore, in applications in which
it is necessary to go below the 0cm position (e.g. turntables, diverters), it is recom‐
mended to dispense with the measuring range 0…20m, or else to remove the first two
position codes 0cm and 3cm.
NOTE
Affix the barcode tape as near as possible to the vertical in order to avoid dust build‐
ups.

5.3.1 Applying barcode tape in horizontal curves
A minimum radius must be complied with for horizontal curves. This depends on the
mounting position of the device. As a rule, the device should be mounted on the axis
of rotation if possible. Tangential differences, referred to below as L, leading to the
device swiveling in or out during the course of a curve mean that larger curve radii are
required. This requirement applies both to outer and inner radii.

5.3.2 Applying barcode tape in vertical curves
To apply barcode tape along a vertical curve, cut the barcode tape at the cut marks
and fan it out. The maximum angle must not exceed 3°. This corresponds to a gap d of
1.5mm. This produces a smallest case minimum radius of 500mm. The voids created
by fanning open should not have a shiny surface, in order to ensure an optimum
function reserve.
