Intended use
2.1
Use limits
2.1.1
The sensors can be used only, if conditions of item 1.1.5 of the present user manual are
met.
2.1.2
Configuration and parameters of the area, where the sensors are installed, and also
requirements to that area should meet requirements of items 1.2.2.1, 1.2.2.2.
2.1.3
The input signal level depends on height and weight of a person, his speed of
movement, point of crossing the area and relief.
2.1.4
The signal at the input of the sensor may be changed influenced by precipitation, small
animals, electromagnetic interference, trees and wings of a gate entering the detection
zone, with amplitude comparable to the human intrusion.
2.1.5
The following factors can affect the input signal: extensive buildings or objects
(fences, walls etc.) near the detection zone, uneven terrain, snow or vegetation on the
area. If such factors take place, due to reflections and interferences the detection zone
is distorted.
2.1.6
On objects with the increased lightning statics, it is necessary to use lightning units.
The lightning units should be used when the length of connecting lines exceeds 300 m.
2.2
Preparation for use
2.2.1
Safety measures
2.2.1.1
Installation, commissioning and maintenance of the sensor are allowed to persons who

2.2.1.2
When maintaining the sensor, the safety rules by working with equipment under
voltage up to 1000 V should be followed.
2.2.1.3
