Warning
. This device works at mains potential. Be sure to take care when working with electricity.
1.
Isolate the mains supply to the circuit at the main consumer unit whenever working on the
connections to the sensor.
2.
Make sure the load is connected and in working order.
3.
Connect the sensor via the plug-in terminal blocks. Live supply to the
L
terminal, load to the
L/
OUT
terminal and Neutral to the
N
terminal, all on the green terminal block. Earth to the
E
terminal stud on the sensor body. Dimming and external input connections should be made via
the plug-in terminal blocks as required according to the applicable wiring diagrams shown in
section 6.
4.
Two relay channels are provided, switched live and low voltage
—
if the channel is being used, set
the jumper to ―Auto‖, if it is not being used, set the jumper to ―OFF‖. To verify that the channel is
working, the jumper can be set to ―ON‖.
5.
Set the sensitivity to maximum (fully clockwise) and range to the desired distance. Note that the
range varies between 5m (minimum) and 30m (maximum) when using the adjusters. Alternatively,
use the DD-LCDHS-LR to set these parameters.
6.
Set the sensor to the appropriate angle then apply power and vacate the area for a minimum of 30
seconds while the sensor builds a ‗picture‘ of the area. Note that every time the sensor‘s range is
changed or the sensor is power-cycled, this step must be observed to ensure the proper operation
of the sensor.
7.
Walk towards the sensor until the load comes on, to find the detection range. The use of the ‘Walk
Test‘ setting using the DD
-LCDHS-LR will aid in finding this point by observing the flashing LEDs
within the sensor.
8.
Tune the sensor range to the desired point by adjusting the range and repeating from step 6. Note
that a large metallic object may be detected up to 2m further away than a person - sufficient
adjustment must therefore be made to account for this.
9.
Once the range has been set correctly, the sensitivity should be reduced as far as possible to a
point which still gives reliable detection at the same range.
10.
For dimming applications, set the light output level by using the lux adjustment.
During operation the output level varies very gradually. However when the lux level is
changed the unit automatically enters setup mode: in this mode the output level varies
rapidly. After the setup time the unit reverts to normal
When adjusting the output, allow the output level to settle by changing very gradually
To disable the maintained illuminance function completely, set the lux level to maximum
11.
Select the desired time-out using the adjuster or handset.
12.
Other parameters can be set using the handset, see section 5 for details.
