VITP-PD
Ceiling Presence Detector
The VITP-PD presence detector switches are designed to provide automatic control of lighting via the Vitesse Plus marshalling box. They detect movement using a
PIR sensor and turn the load on. When an area is no longer occupied the load will
switch off after an adjustable time out period.
An adjustable internal light sensor provides additional energy saving in lighting
applications. When an area is occupied lighting is only switched on when the level
of natural light is below a preset level.
When the unit is first powered up the PIR sensor will always detect immediately
regardless of whether the room is occupied.
Wire the products simply by connecting to the relevant port of the
Vitesse Plus marshalling box using a Cat5 patch cord. An additional
RJ45 connector is provided to daisy chain sensors together.
The detector should be sited so that the occupants of the room fall
inside the detection pattern shown overleaf, at a recommended
height of 2.8m on the ceiling. Note that the lower the sensor is installed the smaller the detection range will be, subject to the parameters shown on the diagram.

Installation
1. Connect the unit to the marshalling box.
2. Set the LUX level to maximum and the time to minimum.
3. Apply power, the load should come on immediately.
4. Vacate the room or remain very still and wait for the load to switch off (should take no more than 2 minutes).
5. Check that the load switches on when movement is detected.
6. To set the final LUX level wait until the level of natural daylight is just enough that lighting is required. Starting with the LUX control fully clockwise (at minimum), very slowly turn the control anti-clockwise until the lights come on. Note that when the LUX control is at maximum then the
lights will always come on with occupancy.
7. Set the time required.

Detection Pattern
Fault Finding
LOAD DOES NOT COME ON
Check to see if the Vitesse Plus marshalling
box is powered up and the wiring is correct.
If the supply and wiring are good, check the
LUX level setting. Increase the LUX level setting to allow the controller to turn on at higher
ambient natural light level.
If the detection range is smaller than expected,
check the diagram above. Rotating the sensor
slightly may improve the range.
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for
longer than the selected timer setting.
Make sure that the sensor is not adjacent to
circulating air, heaters or lamps.
