Step 5
Repeat Steps 3 & 4, walking at various
distances and angles to the unit. This will
help you to establish the detection pattern.
Step 6
If the detection area is too small for your
requirements, try angling the sensor head up.
This should increase the coverage distance.
Similarly, angling the head downwards will
reduce the range should a smaller coverage
area be required. You should find that the
head will move quite freely in its ball-and-
socket mounting.
Step 7
Carry out Walk Tests and adjustments until
you are happy with the coverage area.
Setting up for automatic
operation
When Walk Tests are complete, the unit can
be set for automatic operation as follows:
Step 1
The TIME setting controls how long the lamp
load remains illuminated following activation
and after no further movement is detected.
The minimum time (TIME control fully anti-
clockwise) is approx. 5 seconds, whilst the
maximum time (TIME control fully clockwise)
is approx 15 minutes. Using a flat bladed
screwdriver, set the control to the desired
setting between these limits.
Step 2
The LUX control determines the level of
darkness required for the unit to start
operating each evening. The setting is best
achieved by the following procedure:
- Set the LUX control knob fully
anti-clockwise. Wait until evening.
- When the ambient light level reaches the
level of darkness at which you wish the
lamp to become operative (i.e. at dusk),
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 over a period of a few
days. If you find that the unit is starting to
operate too early (i.e. when it is quite light),
adjust the control slightly anti-clockwise.
If the unit starts to operate too late
(i.e. only when it is very dark), adjust the
control slightly clockwise.
Continue to adjust until the unit operates
as desired.
