The sensor used in PHOTASGARD
sensitivity is in the range of 350 nm to 820 nm. Therefore with its special filter the sensor is predestined for exposure measure ment of
daylight and ⁄ or for measuring artificial light of high colour temperature (similar to sunlight).
COMMISSIONING: Open the cover by carefully loosening the centric screw and remove the cover. If you want to set the brightness dependent
movement, set the threshold value for the desired ambient conditions using the "Threshold" potentiometer. The "Hold time" potentiometer is
used to set the hold time. The other potentiometers are used to calibrate the respective measured variable.
NOTES (W): This device is used for the detection of persons in up to 10 meters distance. The temperature difference between persons to be
detected and ambience must be greater than 5 K. When motion is detected, the potential-free relay output switches. The hold time for the
output, measured from the time when last motion was detected, can be pre-set between 4 seconds and ca. 17 minutes. The sensor is characterized
by its wide reach while being small in size. The potential-free changeover contact is used for switching extra-low voltage only.
In all KINASGARD ® motion sensors and presence detectors, a high-end variant infrared sensor with enlarged angle of aperture is exclusively
used. Because of the patented lens system with 20 individual lenses, only very small dark areas are resulting, which even at a distance of 10 m
are only a few centimeters wide, safely detecting also small motions. The sensor recognizes changes in the infrared radiation spectrum, so in
heat radiation, resulting form the movement of persons or objects. Such movements generate a temporary change of the temperature gradient
in the field. Because of the always present body (heat) radiation, this sensor is excellently suitable for the detection of persons. The temperature
difference between sensor and object must be > 5 K.
