2. At dusk when you find the LUX level desired for operation, set the LUX
control knob to the position that the motion sensor will become active as
daylight declines.
SENSOR ADJUSTMENT
The sensitivity adjustment may be adjusted to compensate for seasonal
variations in temperature and to reduce unwanted activation. The optimum
sensitivity can be achieved by setting the SENS control knob initially to its mid-
point and then adjusting the control knob clockwise to increase the detecting
distance (up to 10 meters) or anti-clockwise to decrease the detecting
distance (down to 3 meters).
ADJUSTING THE FIELD OF DETECTION
The field of detection of the infrared
sensor can be adjusted 30 degrees in
either horizontal or vertical direction.
By means of horizontal adjustment,
the permanent 180
o
field of detection
can be infinitely directed to the right
or left of the mounting position.
By vertical adjustment, the detection
range can be reduced or
lengthened. This can be used to
reduce to incidence of unwanted activation caused by movements from
neighbours and from the street.
The best sensing is achieved by approaching the field of detection
perpendicular to its axis.
A delayed response is often obtained if the field of detection is approached
along the direction of its axis.
