MWS6-DD
Ceiling microwave presence detector – DALI / DSI
Overview
The MWS6-DD microwave presence detector provides
automatic control of lighting loads with optional manual
control. The MWS6-DD 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.
Output Channel 1 comprises a mains voltage relay capable
of simple on/off switching, while Output Channel 2 provides
dimmable control of either DALI or DSI type ballasts.
Functioning as a presence detector, the unit can turn lights
on when a room is occupied and off when the room is
empty. Optional settings allow lights to be turned off in
response to ambient daylight, or to implement a maintained
illuminance (daylight harvesting) system.
The flexibility of having two channels and two switch inputs
allows the following example scenarios:
Dim an outside row of luminaires whilst internal fittings
are switched
Provide absence detection for two separate channels
Maintained illuminance system with manual up/down
controls
All functionality is fully programmable using an IR handset.

Installation
Choosing a Suitable Location
The detector should be sited so that the occupants of the room fall inside the detection pattern shown opposite).
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.
Sensor functionality
Detection Mode
The Detection Mode for both output Channels 1 and 2 can be set to behave in Presence or Absence mode:
Presence When movement is detected the load will automatically turn on. When the area is no longer occupied the
load will automatically switch off after an adjustable time period.
Absence The load is manually switched on. When the area is no longer occupied the load will automatically switch
off after the adjustable time period has elapsed.
In either case, 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
Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level
parameters.
Maintained Illuminance (daylight harvesting)
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 or daylight harvesting).
Burn-in
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 MWS6-DD is able to dim the lamps
using DALI/DSI, 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.

Power-up test procedure
When power is applied to the unit, the load will turn on immediately.
Set the timeout to 10 seconds, 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.
The unit is now ready for programming.
Fault finding
What if the load does not turn ON?
Check that the live supply to the circuit is good.
Check that the load is functioning by bypassing the sensor (e.g. link terminals L and L/ Out on Channel1).
If the detection range is smaller than expected, check the diagram on page 2. Rotating the sensor slightly may
improve the detection range. If still reduced it may be compromised by the ceiling construction / material. Add the
supplied 20mm spacer ring. See page 4 for fitting details.
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 Time Out Period.
Make sure that the sensor is not adjacent to vibrating surfaces or objects (e.g. ventilation equipment).
The unit may pick up movement through glass, thin partitions or walls. Reduce the sensitivity.

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.
When a manual operation occurs, either via the switch input or the infrared, it
invokes the timeout period.
Example 1: a detector in presence mode has a detector timeout of 15 minutes and
a manual timeout of 3 minutes. W hen the user leaves the room they press the off
button. The sensor will revert to automatic after 3 minutes, and then walking back
in the room will turn the lights on.
Example 2: using the settings above, the user turns the lights off (say for a
presentation) but stays in the room. Every time a movement is detected, the
manual timeout period is re-triggered, but when it doesn’t pick up for the short
timeout period, the sensor will timeout and revert to automatic. This means the
lights may turn on inadvertently during the presentation, if the occupants are still
for the manual timeout period, so adjust the timing carefully.
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. Lux Time
enables absence detection to be implemented with a lux off level set. When the
button is pressed, the lights will go on, regardless of ambient light level. However,
if there is sufficient ambient light, they will turn off again after the Lux Time. Note
that whenever the an external switch is pressed, whether in absence or presence
mode, if the lights were out because of the lux level, they will be immediately
turned on again for at least the Lux Time.
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.
Disables detection, leaving the relay output permanently off with the dimming
output operational. This mode is used when the unit is for maintained illuminance
only.
The On Delay to allows the first channel to switch on after the second channel. A
typical application for this would be where a detector is controlling lighting and air
conditioning in an area. When the occupant is detected, the lighting will be turned
on immediately, whereas the air conditioning may be turned on after 15 minutes. If
the area is vacated and the detector times out before the delay, then the air
conditioning would never go on. The delay can be set only for channel 1 using the
on delay parameter.
When the detector turns off, a delay is instigated to prevent retriggering. In certain
circumstances this delay may not be enough. T his parameter allows the delay to
be changed.
