1. Connect a Cat 5 (RJ45) patch lead from the back of the sensor to the relevant port on the
VitessePlus marshalling box. An additional RJ45 connector is provided to daisy chain
sensors together when being used with non-dimming marshalling boxes.
2. The detector should be sited so that the occupants of the room fall inside the detection pattern
shown in section 5, at a recommended ceiling height of 2.8m. Note that the lower the sensor is
installed the smaller the detection range will be, subject to the parameters shown on the
diagram.
3. Mount using one of the two options above overleaf.
4. On the side of the unit, use a small screwdriver to set the SENSITIVITY adjuster to maximum
(fully anticlockwise); the LUX level to maximum (fully anti-clockwise), and the TIME to
minimum (fully clockwise).
5. Power the unit up - the load should come on immediately.
6. Vacate the room or remain very still and wait for the load to switch off (this should take no
more than 2 minutes).
7. Check that the load switches on when movement is detected.
8. If required, adjust the sensitivity level down to reduce the range of detection.
9. For dimming applications the LUX adjuster determines the maintained illuminance level. When
the LUX is set to maximum (fully clockwise), maximum output will be seen from the dimming
ballasts. Adjust this down to get a lower output if required.
10. Select the time using the adjuster, fully anticlockwise is the maximum.
11. Using the UHS or UHS3 infra-red handset: the override on button turns the unit on
permanently; the override off button turns the unit off permanently; the cancel button cancels
the overrides. When an override is selected an LED will flash behind the lens inside the unit.
The UHS handset can also be used to set the lux levels - please refer to Section 4 (page 6) for
further details.
12. Using the DD-LCDHS programming handset; all the above parameters can be set - please
refer to Section 4 (page 7 and 8) for further details.
