TYPICAL WIRING DIAGRAM

ADJUSTING THE CONTROLS:

It is assumed for the purpose of these instructions that the sensor will be connected to a floodlights

(total load <10 amps).

ADJUSTMENT CONTROLS DIAGRAM

75mm

The controls for 'TIME' , 'LUX' and 'SENS' (sensing distance) are all adjusted from the base of the sensor

head and are adjusted by the use of a small flat screwdriver. Care should be taken not to apply excessive

force to these controls.

TIME CONTROL

The 'TIME' control adjusts the length of time that the sensor remains on after being triggered. The time can

be adjusted from a minimum of 5 seconds (-) to a maximum of 7 minutes (+). This control can be adjusted at

any time with immediate effect however adjustments during the 'on' cycle should be avoided.

LUX CONTROL

The 'LUX' control allows the user to determine at what level of background light the unit will function. If the

control is moved to the sun position

the unit will trigger under full daylight conditions and if the control is

moved to the moon position

the units will only trigger in complete darkness.

As a guide the setting for triggering at dusk is when the control is ¾ the way between the

symbols.

Tip: To ensure triggering at your preferred light level, your initial set-up adjustment should be carried out at

the time of day you require your lights to illuminate. When the ambient light has reached your preferred level,

simply adjust your sensor to the point where your flood light illuminates.

SENSING DISTANCE CONTROL

The 'SENS' control allows the user to control the distance at which the unit will detect movement. Moving

the control (+) position sets the sensing range to maximum (approx.10 metres), while moving the control to

the (-) position sets the sensing range to a minimum (approx.1 metre).

SET UP AND ADJUSTMENT

Initial set up can be made during normal daylight hours with the final 'LUX' adjustment made later during the

required ambient light level:

1. Turn the power to the unit off at the wall light switch.

2. Adjust the 'TIME' control to minimum (-) on time.

3. Turn the 'LUX' control to

for daylight operation setting.

4. Turn the power on. (Note: Floodlights will remain on for approx. one minute as the unit resets and warms

up.)

5. Direct the sensor head window towards the area that requires monitoring.

6. Create movement in the monitored area and adjust the 'SENS' control until the correct triggering distance

has been achieved.

7. Increase the 'TIME' adjustment to your required floodlight illumination time.

8. The 'LUX' adjustment can also be made at this time, however its strongly recommended that the final

adjustment to the 'LUX' control is best made at the time of day when the background lighting level is

correct.

AUTOMATIC OR MANUAL MODE OPERATION

Your sensor unit can be operated in either an automatic or manual over-ride mode.

- The automatic mode will function as described above with the floodlights triggered by motion and

remaining illuminated for the selected time.

- The manual over-ride will allow the floodlights to remain on continuously.

The user can switch between manual and automatic modes with the light power switch.
