VITP-MW3A
VitessePlus microwave presence detector
The VITP-MW3A microwave presence detector provides
automatic control of lighting loads via the VitessePlus
marshalling box.
The VITP-MW3A detects movement using a highly
sensitive microwave detector. This works by emitting low
power microwave signals and measuring the reflections as
the signals bounce off moving objects.
Functioning as a presence detector, the unit can turn lights
on when a room is occupied and off when the room is
empty. When used with a non-dimming LCM settings allow
lights to be turned off in response to ambient daylight. If a
dimming LCM is used the detector can be set-up to
implement a maintained illuminance (constant light)
system.
The VITP-MW3A has a unique adjustable sensor head that
allows the area of detection to be optimised for the
application.

Note. If the range is compromised by the ceiling construction /
material. Add the supplied 20mm spacer ring. See page 3 for
fitting details.
Sensor functionality
When movement is detected the detector sends a signal to the VitessePlus marshalling box (LCM). The LCM is
programmed to either, turn on the load (Presence) or the load is manuallly turned on via a switch (Absence). When the
area is no longer occupied the load will automatically switch off after an adjustable time period.
Sensitivity to movement of the microwave sensor can be adjusted using the Sensitivity parameter.
HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.
Switch Level On/Off (with non-dimming LCMs only)
Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level
parameters. See page 7 for programming details.
Maintained Illuminance (with dimming LCMs only)
The detector measures the overall light level in the detection area and calculates the correct output for the luminaires, to
achieve a preset lux level (maintained illuminance).
Burn-in (with dimming LCMs only)
Overview
It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of time
to guarantee lamp life (refer to the manufacturer’s datasheet for details) As this VITP-MW3A is able to dim the lamps via
the VitessePlus LCM (lighting control module), the product provides a facility to disable this for a given period of time.
Operation
By setting the “Burn in” parameter, you can select a time during which the lamps are not allowed to deviate from
maximum output. The unit counts the time, and even remembers how long has elapsed in the event of a power failure.
To cancel the burn in function, simply select a time of 0. Note that when the lamps are changed, the burn in time should
be set again.

Choosing a Suitable Location
The VITP-MW3A is designed to be ceiling mounted and must satisfy the following criteria:
Avoid positioning the unit where direct sunlight may enter the sensor element.
Do not site the sensor within 1m of any lighting, forced air heating or ventilation.
Do not fix the sensor to an unstable or vibrating surface.
Avoid metallic objects directly in front of the sensor head.
The VITP-MW3A is designed to be mounted using either:
Flush fixing, or
Surface fixing, using the optional Surface Mounting Box (part no. MWS3A-DBB).
Both methods are illustrated below.

Power-up test procedure
When power is applied to the unit, the load will turn on immediately.
Set the timeout to 10 seconds (commissioning only) vacate the room or remain very still and wait for the load to switch
off .
Check that the load switches on when movement is detected.
Fault finding
What if the load does not turn ON?
Check to see if the Vitesse Plus marshalling box is powered up and the wiring is correct. Disconnect both RJ45
connections on the Cat 5 patch lead and re-connect, ensuring that they “click” into position, making good connection.
Check that the “lux hold off” setting is not keeping the lights off because there is sufficient ambient light.
If the detection range is smaller than expected, check the diagram above. Rotating the sensor slightly may improve
the range. If still reduced it may be compromised by the ceiling construction / material. Add the supplied 20mm
spacer ring. See page 3 for fitting details.
If the LED is flashing at regular intervals, this shows that the detector is being overridden. Press the cancel button on
the handset.
HINT: The Walk Test LED function can be used to check that the unit is detecting movement in the required area.
What if the load does not turn 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.
If the LED is flashing at regular intervals, this shows that the detector is being overridden on. Press the cancel button
on the handset.
Readback function (UNLCDHS handset only)
The UNLCDHS has the ability to read back the settings stored in a device.
To read back individual parameters
Navigate to the parameter and press the ‘R’ (Read) button whilst pointing at the device. The handset will click
when the parameter has been read back, the device will flash its LED, and the value will be shown against the
parameter in the menu.
To read back all of the parameters in a menu
Press and hold the ‘R’ (Read) button for more than 1 second.
The handset will click every time a parameter is received
The device will show multiple flashes of its LED
All of the values will be shown against the parameters in the menu.
The individual parameters may be edited and then saved as a ‘Macro’.
Notes
If a parameter(s) has been missed because of a communication error, the missing value(s) is replaced by dashes.
When reading back, the outputs of the LCM will temporarily be switched off, and will return to their normal state 2
seconds after the read back has been completed.

Basic programming - UHS5
The functionality of the VITP-MW3A is controlled by a number of parameters which can be
changed or programmed by any of the following devices:
UHS5 Infrared Handset. See below for programmable functions.
UNLCDHS Infrared Handset (with LCD). See user guide for full programming details.
For most basic programming operations the UHS5 handset can be used and the following procedures
are based on using this device.
Point the handset at the Sensor and send the required programming commands to the unit as shown
below.
Valid commands will be indicated by a red LED flash. See page 1 for details of other LED responses.
Note: other functions on the UHS5 which are not shown below are not applicable to this product.

When set to On this causes a red LED to flash on the sensor when it detects
movement. Use this feature to check for adequate sensitivity levels.
Once the detector is turned on, this value sets how long the lights will stay on once
movement has ceased. Select 0 for 10 second delay – use for commissioning only.
Sensitivity level for detecting movement when the detector is already on. *UHS5
sets Sensitivity On and Off to the same value.
Sensitivity level for detecting movement when the detector is off. *UHS5 sets
Sensitivity On and Off to the same value.
If the detector measures the lux level and decides that the output needs switching
on or off as a consequence, the lux time must elapse first. If at any time during the
timed delay the lux change reverses then the process is cancelled.
Select No for a 30 second delay on start up. If Yes is selected, there will be no
delay on start up and the detector will always power up detecting.
Restores factory default settings
Increase light level. Reverts when occupancy cycle complete.
Decrease light level. Reverts when occupancy cycle complete.
If the lights are off, sending the IR command will turn them on immediately and
revert to automatic operation using the manual timeout period.
If the lights are on, sending the IR command will turn them off immediately. After
the manual timeout period (described above), the sensor will revert to automatic.
