1. Introduction
The TLS 500 measures the reflection from objects
compared with background reflection. Any change in
the values is detected as an object and the output
switches.
1.1. Functionality
After switching on the TLS 500, it calibrates a
background measurement and saves this as a
reference value. When an object enters the detection
area, the reflection value changes.
The bigger the difference in light reflection between
the object and the background, the easier it is to
detect said object. High sensitivity comes from a
clear contrast between a detectable object and the
background: For example curtain, cloth, rubber,
asphalt, wood, concrete, earth, terracotta, cardboard
in comparison to people.
Poor sensitivity comes from a reflecting background
like marble, metal, glass, bright objects on bright
background, dark objects on dark background and
no background (the sensor does not see the floor).
1.2. Features

2.2. Setup
It is recommended to carry out the system
installation according to the following steps:
1. Switch off main power for the installation area
and mark it clearly with out of service.
2. Complete the configuration of the TLS 500 by
adjustment the potentiometer (VR- and P-types only)
3. Screw the TLS 500 to the chosen location.
Important:
Do not over-tighten the mounting screws.
Do not drill additional holes into the TLS 500.
2.3. Configuration (VR- and P-types only)
There is a potentiometer at the back of the TLS 500.
1. Open the cover at the back of the TLS 500
carefully with a slotted screw driver.
2. Turn the potentiometer to either fully left or fully
right.
3. Adjust the potentiometer with a screw driver
according to the application.
VR-Type
On the VR-type, the operation range can be
adjusted.
Figure 3: VR-Type – Adjustable operating range (in m)
Because of different reflection ability, a correction
factor has to be taken into account for setting the
sensing distance.
Reference material Correction factor f
Kodak white 1.0
Kodak grey 0.6
Bright concrete 0.6 ... 0.8
Dry gravel 0.4 ... 0.5
Dark carpet 0.3 ... 0.5
Grey plastic floor (PVC etc.) 0.4 ... 0.8
Wood bright, cardboard brown 0.7 ... 0.8
Glass, metal plate 90° 1.2 ... 2.0
Black floor, asphalt 0.4 ... 0.5
Cotton white 0.5 ... 0.7
Card board dull black 0.1 ... 0.3
Condition: Beam axis perpendicular to surface
Example: TLS 500-VR on a wooden floor
Mounting height = 3 m and f = 0.7 … 0.8
Range setting: 3 m / 0.75 = 4 m
P-Type
On the P-type, the recalibration time can be
adjusted.
Recalibration time means the time until an immobile
person or object is accepted by the sensor as
background.

4. When the configuration is completed, close the
cover again.

3.3. Test Input
A test cycle works as follows: The emitter is
switched off and the output recognizes the change
and switches the output.
Important:
Please be aware that this works only with the N- and
P-type when they “see” the floor.
The test input cannot be used with the VR-type and
has to be connected to the Usp.
4. Start-Up and LED status
4.1. Start-Up
1. Switch on mains and/or power up the door
control unit.
2. After start-up, an LED comes on.
3. It is recommended to perform a test procedure
with the door control unit using the test input.
Important:
Check the detection area of the sensor. If
adjustments are needed, please switch off main
power and/or the door controller again for your own
safety.
4.2. LED status
The TLS 500 has a red and a green LED to indicate
its status which is dependent on the type.
TLS 500 type Field free Object detected
PNP-DO Red LED on Green LED on
PNP-LO Green LED on Red LED on
NPN-DO Red LED on Green LED on
NPN-LO Green LED on Red LED on
Example for a TLS 500 N-NPN-LO:
1. The TLS 500 shows via a green LED that there is
no object disrupting the detection area.
2. When a person enters the detection area the
TLS 500 switches the output and the LED to red.
3. The sensor cannot differenciate between an
object and a person. Therefore any object
entering the detection field is also detected.
4. When an object or person does not move for
more than 10 s, the TLS 500 accepts this object

as background and switches the output to free
again.
green red red
< 10 s
green
> 10 s
Figure 7: LED status for the TLS 500 N-NPN-LO
If there is no LED visible, please check the electrical
connections.
If the green LED is blinking (only N- or P-Type):
The sensor either sees no floor or the floor is
specular.
5. Maintenance and Disposal
5.1. Maintenance
Although the TLS 500 does not need regular
maintenance, a periodical functional check is
strongly recommended as follows:
Check the mounting position and detection area
of the sensor.
Clean the sensor with a soft towel and a little
soap water from dust or dirt.
5.2. Disposal
The TLS 500 should only be replaced if a similar
device is installed. Disposal should be done using
the most up-to-date recycling technology according
to local regulations and laws. There are no harmful
materials used in the design and manufacture of the
sensor. Traces of such dangerous materials may be
found in the electronic components but not in
quantities that are harmful.
