3.2. Output signals

The following diagram shows the output signal behavior based on an object detection or test input signal.
Figure 6: Timing diagram

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
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
PNP-DO Red LED on
PNP-LO Green LED on
NPN-DO Red LED on
NPN-LO Green 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
