SECTION FOUR
OPERATION AND TESTING
WALK TESTING PROCEDURE
The sensor will rotate from left to right, and tilt forward or backward. Adjust the sensor to point in
the desired direction.
Set the adjustment controls on the underside of the unit (diagram C) to the following positions:
DUSK - Fully clockwise
DIMMER - Fully anti-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 as the unit goes through its "warm-up" period. After
approximately 1 minutes the lamp will extinguish. 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 illuminate. Now stand still until the lamp extinguishes (this should take approx. 5
seconds).
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.
If the detection area is too small for your requirements, try angling the sensor head up. This will
increase the coverage distance. Angling the head downwards will reduce the range should a
smaller coverage area be required.
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 DIMMER control determines the brightness of the lamp in the dimmed mode. Set the control
between minimum (fully anti-clockwise, dimmer OFF) and maximum (fully clockwise, 60% output)
at the desired level.
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 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. dusk), adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
