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.
• Use a thin flat blade screwdriver to make adjustments.
• The Time control knob at fully anti-clockwise is Test Mode, slightly adjust
to above the T is minimum time approx. 1 min, whilst the maximum time
(fully clockwise) is approx. 30 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
6
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.
