3. Aiming And Adjustment
When power is applied to the sensor, it will start working in
AUTO MODE. If you need to check and adjust the
coverage pattern of sensor, following FIG.F, you canturn
adjusting knob of TIME control to " – ", LUX control to
+
R
º
METER control to "+". Thereafter, you can do "WALKTEST"
and the sensor will operate in any ambient light level and
go off about 6 seconds after each detection.
1. Follow FIG. F – Start outside the pattern and walk across
the pattern until the control unit go on and off, repeat it until
you are satisfied with the coverage.
2. Eliminating unwanted detection. To mask a lens segment,
use the black colour electric tape and cover only the lens
segment which is viewing the potential problem area such as
an open doorway. Caution must be observed so that the lens is not scratched or damaged, after
properly masking a lens segment, recheck by walk testing for proper detection.
4. Normal Operation
Power switch of the sensor ON, the sensor will automatically turn into "AUTO" mode.
This "AUTO" mode is for normal operation.
1. Set the "TIME" control. The minimum setting is about 6 secs. The maximum is about 12 minutes. This
period starts after the movement in the detection coverage.
2. Set the "LUX" control. Turn adjusting knob to (
º
) and the device only operates during the period of
darkness. Turn adjusting knob to (
+ ) and the
R
º
device will operate in any degree of brightness.
Turning the switch OFF will turn off the sensor and the controlled unit. When switching the power switch
ON, the sensor will automatically switch ON (in AUTOMATIC MODE). Leave the power switch ON for
normal operation. The sensor will either switch the light on at night or the whole day – depending on
the setting of the daylight sensor. (LUX)
Note:
-
In
, the timer remains on for about 6 seconds. But, when the object keeps moving in the
auto mode
detecting area, the timer will renew its counting time and not turn off until 6 seconds after the object
stops moving.
-
Conditions which may cause lower sensitivity:
1. On very foggy nights sensitivity may be less due to moisture collecting on the lens
2. On very hot days sensitivity may be less. High ambient temperature and surrounding
inanimate objects may be close to body temperature making the unit appear to be much less
sensitive.
3. On very cold days when heavy clothing is used, especially covering the facial area, very little heat
will be emitted from the body causing the unit to appear less sensitive.

Cleaning – Wipe with damp cloth only. Soaps or polishes may damage the sensor lens.
