8. Setting Up for Automatic Operation
(Auto Mode)
• When the walk tests are complete, the unit can be adjusted for
automatic operation.
• The Time ON setting controls how long the unit remains illuminated following
activation and after all motion ceases.
• The minimum time (fully anti-clockwise) is approx. 3 seconds, whilst the
maximum time (fully clockwise) is approx. 18 minutes. Set the control
to the desired setting between these limits.
• The Dusk (Lux) level setting determines the level of darkness required for the
unit to start operating. The setting is best achieved by the procedure below;
1. Set the Dusk (Lux) level control knob fully clockwise.
2. 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 knob in
an anti-clockwise direction until a point is reached where the lamp illuminates.
3. Leave the control knob 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
(i.e. when it is quite light) adjust the control knob slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark).
Adjust the control knob slightly clockwise.
• Continue to adjust until the unit operates as desired.
• Walk across the detection area. Each time you are detected the lamp
will illuminate.
• Now stand still until the lamp extinguishes (this should take approx. 3 seconds).
Start moving again after 2 seconds, and the lamp will illuminate.
• Repeat the above, walking at various distances and angles to the unit.
This will help you to establish the detection pattern.
• If the detection area is too small for your requirements, try angling the sensor
head up. Angling the head downwards will reduce the detection area should
a smaller range be required.
