Setting Up for Automatic Operation
When walk tests are complete, the unit can be adjusted
for 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. 18 minutes. Set the control to the
desired setting between these limits.
The DUSK control determines the level of darkness
required for the unit to start operating. The setting is
best achieved by the procedure below:
Set the DUSK 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 (a small step at a time) rotate the control in a
clockwise direction until a point is reached where the
lamp illuminates. Leave the control set at this point.
Start moving again. As you cross each "zone" 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.
Masking the Sensor Lens
To reduce the sensor coverage, preventing detection in
unwanted areas, mask the sensor lens using the lens
mask sticker supplied (see diagram D). For your
information, the centre section of the lens covers short
range detection, and the outer edge of the lens covers
long range. Mask the sensor to suit your installation.
