TL01-Asensordescription
TL01-A is a microcontroller optic-electronic sensor that can detect printed lines, printed contrasts and
working material edges.
It can work with a contrast lamp when the internal lamps are inactive.
It is fitted with four keys for the calibration and to access the sensor’s advanced functions.
It features a four-digit display and a led-bar, used to indicate certain sensor parameters and the
positioning of the line/edge. There are LEDs used to provide further information on the operating status:
Main features
Reader of edges and coloured, continuous or interrupted lines on various backgrounds:
Printed light, printed dark, glossy, transparent, metallized, reflective, etc.
Easy to use:
Simple focus. Adjustment needs to be performed just once during the installation, even if the
material being used changes.
Immediate display of the reading area with the Laser pointer.
Simple and quick calibration in just a few seconds.
Automatic selection of the illumination colour for maximum contrast (the sensor activates the blue,
red or white lamps autonomously to achieve the maximum prominence of the line or edge).
Illumination for matt or glossy surfaces.
Possibility to disable the lamps if a contrast lamp is used.
Micrometrical electronic movement (E.M.D.) of the reading position, with the right and left arrows as
an alternative to the mechanical movement (micrometrical support), without reducing the viewing
area.
Reading metallized or matt surfaces without moving the sensor.
Remote keypad (optional) for installations where access to the sensor is difficult.
Sensor support is simple to adjust, solid and compact.

Quickstart-up
Position the sensor correctly as shown in the previous sections. Use the spacer supplied with the sensor
to find the best angle in relation to the contrast roller (the spacer must be positioned between the sensor
and the roller, so that the reference hole is higher than the sensor). Once the positioning operation has
been completed, remove the spacer.
Make sure that inside the field of view of the sensor there is a contrast to read (e.g. a white sheet with a
black line):
(if necessary, see the end of this manual, for two pages with a black line printed on them which can be
used to perform the calibration)
Focus
1.
2. The display will show a numerical value. Move the sensor closer or further away from the material
in order to achieve the maximum reflection value. The value is shown on the display. Then secure
the TL01-A in that position (if you have used a white background with black line, the value should
be between 4,5 and 8,5)
Optimal distance (maximum value displayed
and led bar completely on)
Too close/far (value displayed is not maximum,
led bar not completely on)
Keep the calibration/ contrast key
pressed for 2÷3 seconds, until the white
and blue lights switch on. When the
display shows “8888”, release the key.
The contrast read by the TL01-A is the
material edge (light), compared to the roller
The contrast read by the TL01-A is given
by the dark line printed on the material

3. If the contrast lamp is used, press the right arrow during the focus in order to disable the internal
lamps of TL01-A. (use the left arrow to activate them)
4. Remove the sheet, if it was used to perform the contrast procedure. Position the line or edge to
follow on the luminous spot:

VIEWING AREA:
The default viewing area of the TL01-A is 5mm.
You can change the field of view of the sensor by a minimum of 1mm and a maximum of 28mm:
1. press the right and left arrows contemporaneously;
2. the field of view, expressed in mm, will appear on the display as a number;
3. press the right arrow to increase the field of view,
or press the left arrow to reduce it;
4. once the desired value has been set, press the line/edge key.
READING DIRECTION:
To change the reading direction, press the line/edge key pressed for about 3÷4 seconds, until
the arrow indicating the reading direction lights up.
EDGE OR LINE:
To select whether to read line or edge, press the line/edge key briefly. The LED for the type of
reading selected, will light up automatically.
Line: Edge:
Line to follow Edge to follow

E.M.D. (Micrometrical Electronic Movement)
If necessary, you can move the line or edge to follow from ±0,1 to ±14 millimetres, from the position
indicated by the laser.
Simply press the right arrow for a positive movement,
or the left arrow for a negative movement.
Once a certain movement value is exceeded (±50% ca. of the viewing area set), the laser indicator
will start flashing.
The movement value will be reset automatically when you access the change the viewing area
function.
Attention! When the line reading mode is selected, the E.M.D. function is blocked each time that the
LED that signals the lack of the index line is active (LED on).
INTERRUPTED LINE FUNCTION:
You can activate the interrupted line function so that when the print is not present, the belt guide does
not perform any adjustment, but it remains in stand-by until the line appears again. This option is
available only if the line reading has been selected.
To activate this function keep the calibration/contrast and the left arrow keys pressed
at the same time. The line reading LED will start flashing, indicating that the function
is active.
To disable the function keep the calibration/contrast and the right arrow keys pressed
at the same time.
Attention! If this function is active, the wait time of the belt guide system must not be set (infinite wait
time) and the Work Zone of the belt guide must be less than 100.
SW VERSION:
Press the calibration/contrast and line/edge keys contemporaneously to display the
Sw version of the TL01-A.
