Function

The TopScan2 series is a modular sensor system that can be used in a flexible manner for various requirements relating to the monitoring of
automatic doors. The system can be mounted for either static or mobile use. The housing can be easily shortened and up to five sensor modules
can be arranged side by side, whereby each beam can be configured individually. When it comes to the operating modes, there is the choice
between background suppression and background evaluation. The light or dark switching modes, detection range and closing edge alignment
can also be adjusted. These features make the TopScan2 active infrared scanner ideal for use with a wide range of automatic door systems.

Configuration information

Configuring the Monitoring Edge

The transmitter of each sensor features two beam position settings via which the monitoring edge can be aligned to the left or to
the right.

Detection range setting:

1. Rotate the adjustment screw counter-clockwise until the LED illuminates

2. Slowly rotate the adjustment screw clockwise until the LED goes out

3. Then rotate the adjustment screw further by 1/8 of a rotation

Angle settings:

By rotating the sensor around its rotational axis (1), the offset (2) of the detection
point to the wall can be easily changed. The angle setting can be continuously
adjusted from 0° to 30°.

Programming:

Both the switching mode and the operating mode can be configured via the
programming switch for each sensor.

Function Principle

The two large-area lenses (one for the infrared transmitter and one for the two photodiode receivers with ambient light filter) have
an optical center-to-center distance of approx. 150 mm, resulting in a light spot size of 75 mm x 75 mm. The angle of the two lens
systems can be adjusted to each other via a precision gear according to the principle of background/foreground suppression.
Such precisely defined focal lengths enable a precision detection range setting of up to 2500 mm.
The detection range can be extended up to 2500 mm and responds to any object in the detection area, with minimal effect from
the surface color and structure. Reflection levels that exceed the specified maximum detection range are not detected by the
sensor, even with highly reflective objects — for example corrugated aluminum plates or marble floors (with background
suppression). The detection fields of several devices can be overlapped without interference.

Background Suppression Operating Mode

In this operating mode, the background is "detected" but not actually evaluated (ignored). A reflection signal from an object within
the specified detection area is required as a switching signal.

Background Evaluation Operating Mode

The TopScan2 can also be used with a test option, regardless of whether or not there is an object/person in the detection area.
The receiver constantly sees the reflected light from the transmitter when the background is present. Testing is performed by
disconnecting the transmitter from the supply voltage.
The background is used as a reflector. If the light beam is broken by an object, a switching signal is triggered.

Application

• Protection mechanism for closing edges on automatic sliding doors and revolving doors

• Anti-collision protection for people/objects in the vicinity of revolving doors

• Edge and pinch protection for sliding doors

• Entry monitoring for buses and trains operated within the public transportation network
