Active Infrared Scanner TopScan-S

Functional Description

2 Functional Description
The TopScan-S is an active infrared triangulation scanner.
The TopScan-S has been designed for sensing while mounted on a swinging door panel.
The intended use of TopScan-S is to make safe automatic swinging doors in com-
plying with German standard DIN 18650. If used as intended, the sensor shall
DIN
influence the door movement through the safe door control only and not by direct
intervention, as only using the safe door controller and the sensor together consti-
tutes a protective device of EN ISO 13849-1:2006 Performance Level "c" Catego-
rie 2.
The modification of the construction/ arrangement of the installation without con-
sultation with the manufacturer could lead to dangerous situations.
2.1

Principle of Operation

Any objects entering the protected area will be detected by the infrared beams and will cause the relay
output to be switched off.
The beam spot produced by the infrared beam on the ground is approx. 1,1 cm x 8,3 cm in size (at a
mounting height of approx. 2 m).
The angle of the two lens systems can be modified by an adjustment mechanism. A sensor mounting
height of up to a maximum of 2.50 m can be set. The sensing range of the device is set to maximum
at the factory. The device includes an optical adjusting tool.
The sensor detects objects in its sensing field with little to no influence by the targets' color and sur-
face finish. Reflective and very dark objects are detected as well.
Several sensors can be operated in a master and slave combination in order to adapt the protected
area to the application's required sensing area (cf. Chapter 7).
By means of a six-position screw terminal, the master module is connected to the door controller. The
slave modules are connected to the master module by means of flat cables. The master module and
the slave modules are located in an aluminum profile together.

Installation and Initial Operation

Installation Check List

3.1.1 Installation of Aluminum Profile

1. Push the module holder (c) into the aluminum profile (b) and position the module holder at the
points where the modules will be mounted later.
2. Drill the mounting holes in the aluminum profile between the module holders (in Fig. 3.1 gray
surface).
Make sure that no chips remain in the aluminum profile.
Seal the borehole when mounting so that dripping water cannot penetrate the housing.

3. Only use flat-head screws to mount the aluminum profile (b) at the intended mounting height
(maximum 2.50 m).
Sawing recommendation for aluminum and plastic profiles:
Use a miter-box saw with a hack saw blade for both profiles.
Make sure that the plastic profile rests with the convex side facing outwards.
Saw carefully (risk of breakage).
The aluminum profile is non-critical during machining.
