µDim Microwave Sensors
The µDim series of miniature microwave presence detectors provide automatic control of lighting loads with optional manual control. The unit comes
complete with a selection of fixing clips, allowing unobtrusive flush mounting of the sensor head into ceiling tiles or on to solid surfaces. It has been
designed so that it can be used for ceiling mounted or wall mounted applications. As microwave radiation penetrates plastic and glass, this unit has
been specifically designed to be mounted inside a luminaire.
Three versions are available: switched, 1-10V analogue, and DALI. All of which will switch incandescent, fluorescent and compact fluorescent
lighting.
The unit detects movement using a microwave sensor and turns the load on. When an area is no longer occupied the load will switch off after an
adjustable time out period has elapsed.

Power supply unit
• Connect the power supply via the terminal block on the power supply unit as shown overleaf. Live supply to the L terminal,
Neutral to the N terminal and the load to the LIVE OUT (L/out) terminal.
• Connect the sensor head to the power supply unit using the RJ11 connector, ensuring it “clicks” in place.
• In the case of dimming applications, connect the D+ and D_ connections to the corresponding terminals on the luminaire
dimming ballast.
• On power up, the load should come on immediately.
• Vacate the room or remain very still and wait for the load to switch off (on the factory preset, this should take approximately
15 minutes, but the timing out period can be adjusted down to 1 minute to help speed up the setup procedure — please
see next section for details on set-up & adjustment).
• Check that the load switches on when movement is detected.

5. Setup
µDim
Doc No: T13 144 1C
Setup
Positioning
• The detector should be sited so that the occupants of the
room fall inside the detection pattern shown in picture. Please
note that when ceiling mounting, the recommended ceiling
height of the sensor head is 2.4m. Note that the lower the
sensor is installed the smaller the detection range will be,
subject to the parameters shown on the diagram.
• Avoid direct sunlight entering the sensor.
• Do not site within 1m of forced air heating or ventilation.
• Do not fix to a vibrating surface.
• Avoid metallic objects directly in front of the sensor head.
• Do not fit to a suspended luminaire.
Settings adjustment:-
• On initial power up, the factory set default settings are:-
• Time = 20 minutes.
• Lux = Maximum (i.e. lights will switch on in full daylight on
detection).
• Sensitivity = Maximum.
Time
All versions — set the time period using the programming handset (see
section 6). The factory default is 20 minutes.
Lux
SL-MW-SW — the switch level on lux setting determines the ambient
light level at which the lights turn on. This can be set using the
programming handset (see section 6). Setting to maximum (level 7)
ensures that lights always come on (this is also the default setting).
SL-MW-AN/DA — switch level on described above is available using
the programming handset only. The push button lux adjustment
determines the dimming output level and can be set using push button
the programming handset light level and works as follows:
• During operation the output level varies very gradually.
However when the 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, allow the output level to settle by changing
very gradually.
• To disable the constant light function completely, set the level
to maximum.

LOAD DOES NOT COME ON
Check to see if the live supply to the circuit is good. Strap across the L
and LIVE OUT (where used) terminal to turn the load on.
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.
If the unit “false triggers” reduce the sensitivity using the sensitivity
settings (see section 4 and 5).
