Active infrared scanner

The programming switch can be accessed by carefully removing the cover with the lens assembly from the housing. A small slot-

head screwdriver can be used to carefully lift off the cover by the slots located on the sides of the cover.

Each switch is on when the switch position is down (ON); if the switch position is up, then the switch is switched off (OFF).

The table below shows the various programming options.

The ProScan is a 12-beam energetic light scanner based on the principles of active infrared. The beams, which are switched

independently, enable the sensor to fan out across an extremely wide and narrow detection field in the area of the door.

The clearly defined, fan-shaped detection field on the ProScan can be set manually in four areas: half fan to the right, half fan to

the left, central fan and full detection field.

Immediately after being switched on for the first time, the ProScan programs the reflected pattern of the detected background as

the reference signal. During this process, the ProScan automatically adapts to the relevant installation and assembly

environment. Since each of the individual light beams on the ProScan independently programs its specific reception level, there

is no need to manually configure complex sensitivity settings.

Once the programming phase is complete, the light reflected from each of the 12 light beams is evaluated. Each time there is a

difference between the reflected value of an individual light beam and the reference signal, a switching process is initiated.

"Open Time" Function

The ProScan is a self-programming device, and automatically adjusts to changes in its environment. If the ProScan detects a

stationary object that does not correspond to the programmed reference signal (for example, a suitcase), ProScan interprets this

as a permanent change in the environment and initiates a new self teach-in process after a preset time (referred to as "Open

Time") has elapsed. Open Time can be adjusted to meet customer application requirements.

"Suitcase" Function

After a background has been changed, the ProScan "Suitcase" function allows the reference to be adjusted back to the original

background. Once a self-taught object, such as a suitcase, is removed from the detection field again, ProScan returns to the

original reference. A new learning process is not required.

Compensating for long-term drifts

The ProScan is able to compensate for long-term drifts. Using this function, changes to the ground reflectance (for example,

caused by rain or snow), as well as temperature fluctuations and dirt on the optical surface or ground are automatically

compensated for.

Test input (optional)

Using the integrated test input, the overall function of the ProScan can be reliably checked by testing all 12 light beams

simultaneously.
