SENS (Sensitivity Adjustment)
•
The sensitivity can be increased by turning the knob towards (+)
and decreased by turning the knob towards (–).
•
Note:
temperature. The sensor is more sensitive at lower environmental
temperatures and vice versa.
TIME
•
The time duration is adjustable from. Turn this knob towards (+) to
increase the time, or turn it towards (–) to decrease the time.
•
Note: Once the light is activated by the PIR sensor, any subsequent
detection will restart the time again from the beginning.
•
The light will stay ‘ON’ until the duration of the time set by this
knob has expired.’
LUX (Lux Control Adjustment)
•
The LUX control has a built-in photocell that detects daylight and darkness .
•
☀
– Turning the LUX knob into this position means that the PIR sensor will turn the light ON at ‘Daytime’
(as well as at night time).
•
☽
– Turning the LUX knob into this position means that the PIR sensor will turn the light ON only at ‘Night’.
•
Desired LUX level can be set by adjusting the LUX knob between the ‘Daytime‘ and ‘Night’.
The PIR motion sensor has three adjusting knobs:
SENSITIVITY, TIME
and
LUX
.
Motion Sensor Settings
Good sensitivity walking
across the detection area.
Poor sensitivity
walking towards or
away from the sensor.
WALK THROUGH TEST
•
Set the TIME knob to min (–) the LUX level to (
☀
) and SENS knob to (+) position and wait approximately a minute
for the control circuit to stabilise. Do not stand within the sensing range of the sensor!
•
Direct the sensor towards detection area by adjusting the swivel joint on the sensor arm.
•
•
Walk slowly across the detection area. The sensor will detect the infrared radiation of the human body and turn
the light ON.
•
Test the coverage of the area by walking further away from the sensor until you get satisfactory result. Adjust the
direction of the sensor left or right or up or down if required.
•
Once you are happy with the direction, don’t forget to set the TIME and re-adjust the SENSITIVITY and LUX level
required from day (
☀
) to night (
☽
) operation.
