TOF/Spot-car detection Installation guide
Overview
Electrical connection
Introduction
The TOF/Spot-car detection has an operating range of 3 m. The sensor measures the distance to an object. As soon as
the object is detected within the threshold, the output is switched. The sensor is able to detect all types of car surfaces,
independent of their colour or reflectivity.
Installation
The installation has to be carried out according to the following steps:
1. Mark clearly that the modifying system is out of service and switch off main power.
2. Define ideal position (optical axis min. 150 mm to parallel surface).
3. Drill a hole at the required position or use a mounting bracket.
4. Snap the TOF/Spot-car detection into the hole or mounting bracket
5. Connect the sensor to the control unit.
6. Teach-in the desired range
The TOF/Spot-car detection has been specially developed to monitor the area directly beneath a car park barrier.This ensures
that if a car remains under a raised barrier, the barrier cannot be lowered to damage the car.

Select the desired output logic for your control unit with the output selector (gray wire)
1. Place an object at the desired threshold
distance.
Attention: An offset of 150 mm is
required
2. Press the teach-in button on the rear side
of the sensor for more than 2 seconds
3. The status LED starts to blink for
approximately 30 seconds.
4. The threshold distance has been set
as soon as the LED stops blinking and
switches off.
5. Check functionality

Objects must interrupt the complete cross-section of the beam to be detected properly. If an object only partially interrupts the
beam’s cross-section, a correct distance evaluation cannot be guaranteed.
The enclosure rating of the sensor’s housing is IP65. Additional protection for heavy rain is strongly recommended. An
additional mounting bracket is available.
The sensor needs a background. If there is no background, it is possible that any object detected at a distance of 15 m or more
may be considered to be a car.
