Connect the unit to the mains and switch power on.
After a short delay, the unit will switch ON. This is
indicated by the red LED see diagram C. Any attached
lights will also illuminate.
Setting up for automatic operation
The DUSK (LUX) 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 and Time Delay control knob fully anti-
clockwise. Wait until darkness falls.
When the ambient light level reaches the level of
darkness at which you wish the lamps to become
operative (ie. At dusk), 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.
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 (ie. when it is quite light), adjust
the control slightly anti-clockwise. If the unit starts to
operate too late (ie. only when it is very dark), adjust
the control slightly clockwise.
Continue to adjust until the unit operates as desired.
The Time Delay setting allows the user to determine at
which time after the required darkness level is reached
the lights will illuminate. This is beneficial in areas
where intermittent light/darkness exposure is possible
ie:- car headlights, or shadows.
Turning the adjustment knob fully anticlockwise will
illuminate the lamps 2 seconds after the lower lux level
is reached.
Turning the adjustment knob fully clockwise will
illuminate the lamps 5 minutes after the lower lux level
is reached. This will eliminate possible on/off
switching due to intermittent light/darkness exposure.
