4. Introduction
The TOF/Start is a compact yet powerful sensor which detects
people and objects approaching an escalator and speeds it up in
time for them to step comfortably and safely aboard.
The TOF technology enables the TOF/Start to operate with all types
of backgrounds without any need to recalibrate. Usually mounted
under the handrails or flush mounted in the balustrade at the
approach area, it offers excellent detection capability over an area
of up to 2 m x 2 m with a beam angle of up to 70°.
There are two versions of the TOF/Start:
• The TOF/Start Basic offers people/object detection and a
blanking function to blank out fixed objects, such as bollards.
• The TOF/Start Advanced offers these features plus a cross-
traffic function.
4.1 Application
Figure 1: TOF/Start detects intending passengers approaching
an escalator.
4.2 Features of the TOF/Start
• Excellent detection capability, independent of
reflectance
• Ignores cross-traffic via intelligent direction
recognition
• Individual setting of the detection area
• Detection area operates with all types of background
• Insensitive to ambient light
4.3 Type description
Figure 2: Type description
5. Configuration
5.1 Type of threshold setting
The distance at which the sensor triggers an output is the
threshold. The TOF/Start requires a threshold setting for
the x-axis; note that the y-axis is fixed at 2 m. A factory
setting as well as a mixture of potentiometer and preset
are also possible. For requirements regarding a variable
y-axis, please contact your local CEDES representative.
Note: The sensor uses a ±120 mm (±4.72 in) hysteresis.
The hysteresis is the difference between the switching points
changing the status from 'free field' to 'object detected' and
back from 'object detected' to 'free field' compared to the
nominal limit.
5.1.1 Threshold setting via potentiometer
The threshold distance at which the sensor triggers an
output is set with a potentiometer for the x-axis on both
the Basic and Advanced versions. This is done using the
potentiometer at the back of the sensor. If the sensor points
to a background, the distance of the switching threshold
to the background is recommended to be set at 150 mm.

Important:
The scale is not printed on the sensor. However the
potentiometer can be adjusted in five fixed steps of 0.2
m; starting at 0.6 m (at the 7 o'clock position) up to
1.4 m (at the 5 o'clock position); see Figure 3 below.
Take a small screw driver and turn the potentiometer
to the required position.

6. Installation
Important:
The TOF/Start must be mounted under the handrail at a
minimum 10° mounting angle to the ground facing
upwards.
Figure 4: Mounting angle of TOF/Start
7. Input / Output description and
electrical connection
Generally the TOF/Start has one output that is triggered
if the detection field is interrupted. For this purpose, a
push-pull output is used. With the logic selector (gray wire,
Figure 6), the logic of the output signal can be configured
for “HIGH“ on object or “LOW“ on object operation
(Figure 5), according to the controller requirements.
The logic selection is performed during start-up.

Figure 6: Connection diagram
8. Start-up
1. Switch on mains and power up.
2. Check if LED lights up.
3. Check the distance setting and the reaction of the
sensor, including the status LED, by placing an object
into the detection area at different heights and widths.

10. LED signals
The red LED provides the sensor's status. The respective
LED is dimmed when the power is OK and the detection
field is free. The LED glows bright when an object is
detected and the respective output triggered. The LED is
visible from the front.
Figure 9: LED indicator
11. Cross-traffic
The TOF/Start Advanced features a cross traffic detection
function. If a person moves towards the escalator entrance
area, the TOF/Start Advanced triggers the output. If the
person only moves across the escalator entrance area, the
TOF/Start Advanced recognizes that the person does not
wish to use the escalator and does not trigger the output.
Important:
The cross-traffic activation zone begins at a 1 meter
distance from the sensor.

escalator entrance area. LED status is dimmed.
Figure 11: Person is detected entering detection area, moving
towards the escalator entrance area. LED status is
bright.

escalator entrance area. LED status is dimmed.

escalator entrance. LED status remains dimmed

12. Blanking
Both TOF/Start versions feature a blanking function. The
TOF/Start triggers the output when objects are dynamic
(moving) within the detection field. Static objects within the
detection field will be ignored and blanked out (after 30
seconds). This covers with objects that are already present
at power up (i.e. bollards).
Start-up:
Figure 14: Active blanking - start-up sequence with i.e. bollards.
Figure 15: After start-up the bollards are blanked out
from the detection field.
Active blanking:
Figure 16: The detection field is free.
Figure 17: A static object is placed in the detection field
(i.e a trash bag). The object will be detected.
Figure 18: After 30 s the static object will be blanked out and
the TOF/Start continues its operation with the new
geometry of the detection field.
13. Trouble shooting
If the problem persists, please contact your local CEDES
representative (www.cedes.com).

14. Maintenance
Although the TOF/Start 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 optical window with a soft towel and a little
soapy water.
15. Disposal
The TOF/Start should only be replaced if a similar
protection 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 the quantities that
are harmful.
