SETTING UP FOR AUTOMATIC OPERATION.
When walk tests are complete, the unit can be switched to automatic operation :
The TIME setting controls how long the unit remains illuminated following activation & after
all motion ceases. The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the
maximum time (fully clockwise) is approx. 5 minutes. Set the control to the desired setting
between these limits.
The Lux control determines the level of darkness required for the unit to start operating. The
setting is best achieved by the procedure below:
Set the Lux control knob fully anti-clockwise. The unit will now start operating at dusk.
If you require the light to activate earlier, wait until the ambient light level reaches the level of
darkness at which you wish the lamp to become operative, SLOWLY rotate the control in a
clockwise direction until a point is reached where the lamp illuminates. Leave the control set at
this point.
At this position, the unit should become operative at approximately the same level of darkness
each evening. Observe the operation of the unit. If the unit is starting to operate too early (ie.
when it is quite light), adjust the control slightly anti-clockwise. If the unit starts to operate too late
(ie. dusk), adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
MASKING THE SENSOR LENS
The unit is supplied with a lens mask which allows the option to reduce the range of the sensor.
The lens mask simply clicks over the sensor. When fitting ensure that your chosen option is
facing forwards. The engraved arrow indicates the front of the sensor.
Ensure that the arrow marked on the lens is lined up with the arrow on the sensor. This will then
give an indication of the front of the detection area.
See Diagram H
Engraving on the lens indicates the effect on the detection range each segment will have.
These are 2m, 4m, 8m or 12m.
If no segments are removed then the sensor WILL NOT detect.
The desired range can be achieved by carefully removing the segments then repeating the walk
test after each segment has been removed until the desired detection area is achieved.
