SECTION FOUR
OPERATION AND TESTING
WALK TESTING PROCEDURE
The sensor will tilt forward or backward. Adjust the sensor to point in the desired direction.
Set the two adjustment controls on the underside of the unit (diagram C) to the following
positions: TIME - Fully anti-clockwise
DUSK - Fully anti-clockwise
The unit will now operate during daytime as well as at night, illuminating the lamp 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 minute 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, and there is no motion detected, the unit switches to automatic
sensing.
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(wait for 1 minute before adjusting):
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. The unit may operate when the dusk control is adjusted.
Please wait until the unit resets before making further adjustments. if the unit operates after dusk
setting is done, stop movement for 1 minute. The unit will then settle into normal sensing mode.
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.
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 H). For your information, 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.
