SECTION FOUR
OPERATION AND TESTING
WALK TESTING PROCEDURE
The sensor will rotate from left to right. Adjust the sensor to point in the desired direction.
Set the two adjustment controls on the rear of the unit (diagram C) to the following
positions:
DUSK - Fully clockwise
TIME - Fully anti-clockwise
The unit will now operate during daytime as well as at night, illuminating the lamp at full
power for approx. 5 seconds each time. This allows testing to be carried out to establish the
best position for the sensor.
The lamp will immediately illuminate at full power as the unit goes through its "warm-up"
period. Try to remain outside the detection area during the warm-up period.
Walk across the detection area approx 5 metres from the unit. As you cross a detection
"zone" the lamp will switch to full power.
Start moving again. As you cross each "zone" the lamp will switch back to full power.
Repeat the above, walking at various distances and angles to the unit. This will help you to
establish the detection pattern.
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. 5 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. Wait until darkness falls.
When the ambient light level reaches the level of darkness at which you wish the lamp to
become operative (ie. At dusk), SLOWLY 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.
