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. 12 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;
1. Set the DUSK control knob fully anti 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 in a clockwise direction until a point is reached where the
lamp illuminates.
3. 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 (i.e. when it is quite light) adjust the control slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark).
Adjust the control slightly clockwise.
• Continue to adjust until the unit operates as desired.
Masking the Sensor Lens
• To restrict the sensor coverage, preventing detection in unwanted areas,
mask the sensor lens using the masks provided in the accessory pack
(see diagram below).
• The top section of the lens covers long range detection, the bottom
covers short range. Similarly the left and right lens sections cover the
left and right detection areas respectively.
