Direct Dim Microwave Presence/Absence Detector
Product Guide
CRBMWDD3

page 2
The CRBMWDD3 microwave presence detector provides automatic control of lighting loads with optional
manual control. It can be used on incandescent, fluorescent and compact fluorescent lighting and DSI or
DALI digital dimming ballasts over 1 or 2 channels. The CRBMWDD3 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. The CRBMWDD3 has a unique adjustable sensor
head that allows the area of detection to be optimised for the application.
The dimming channel of the detector can be used to control the light output of luminaires that are fitted
with dimming ballasts. 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).
The switching channel of the detector can either be used to isolate the supply to the dimming ballasts
(saving on the standby current of the ballasts) or to switch a separate channel of standard, non-dimming
luminaires.
Two input terminals can be used to manually override the dimming levels and override the lights on or off.
The flexibility of having two channels and two switch inputs allows the following example scenarios:
1. Dim an outside row of luminaires whilst internal fittings are switched
2. Provide absence detection (see below) for two separate channels
3. Maintained illuminance system with manual up/down controls
An integral infra-red sensor in the unit allows the unit to be programmed using the optional CRPHS
programming handset. This gives complete flexibility over many of the operating parameters. Without the
handset, manual adjustments can be made to the sensitivity, lux and time settings using controls
accessible behind the lens.
The UHS user handset can be used to change output lux levels and override the lights on or off.
Two standard units are available:
CRBMWDD3 - presence detection:
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.
CRBMWDD3/ABS - absence detection:
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. Note that the CRBMWDD3 can be programmed to
absence detection using the programming handset.
In most applications the CRBMWDD3 can be used with simple manual adjustment. However, the
CRBMWDD3 unit has a comprehensive set of features that can be set using the CRPHS handset.
Alternatively the units can be commissioned as follows:
On-site commissioning service - please contact our sales department for details.
Pre-commissioning service - the units will be despatched to site with the correct features set. The
part number will read CRBMWDD3/PRG followed by the project reference number. Please contact
our sales department for details.

Ideal for large office or classroom
Ideal for corridor or aisle applications
Ideal for open plan areas and offices
LOAD DOES NOT COME ON
Check to see if the live supply to the circuit is
good. Strap across the L and LIVE OUT 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.
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for a
greater time period than the time out period set
using the switch.
Make sure that the sensor is not adjacent to
vibrating surfaces or objects (e.g. ventilation
equipment).
The unit may pick up movement through thin
partitions or walls. Reduce the sensitivity by
turning the adjuster anticlockwise.

3. Wiring & Fixing
Wire the products using the diagrams shown in section 10.
To switch from more than one position simply wire two or more units in parallel using the Live,
Neutral, Switched Live and manual switch wires only. The dimming connection must be wired to
one unit only.
The detector should be sited so that the occupants of the room fall inside the detection pattern
shown in section 11.
Corridors or aisles: the unit should be placed at the end of the corridor or aisle and the sensor
head should be angled to look down the corridor or aisle.
Open plan areas and offices: the unit can be mounted in a corner looking outwards in which
case the sensor head should be angled, or the unit can be mounted in the centre of the area
with the sensor head flat.
Note that the higher the sensor is installed the shorter the detection range will be.
Sites as far away as possible from any lighting or ventilation equipment.
Do not fix to a vibrating surface.
Do not fix to a suspended luminaire.
Site as far away as possible from the surface of metal objects.
Mount using one of the two options overleaf.
1. Make sure the load is connected and in working order.
2. Isolate the mains supply to the circuit at the main consumer unit.
3. Connect the sensor via the terminal blocks. Live supply to the Lterminal; load to the L/OUT
terminal; Neutral to the N terminal on the green terminal block. Dimming / external connections
should be made as required according to the applicable wiring diagrams shown in section 10.
4. Use a small screwdriver to set the LUX level adjuster fully clockwise, the time to minimum (fully
anticlockwise) and the sensitivity to maximum (fully clockwise) using the diagram in section 8.
5. Apply power—the load should come on immediately.
6. Vacate the room or remain very still and wait for the load to switch off (should take no more than 2
minutes).
Check that the load switches on when movement is detected.
7. For dimming applications, set the light output level by using the LUX adjustment thumbwheel or
the handset. See section 9 for handset operation.
During operation the output level varies very gradually. However when the LUX 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 the output, allow the output level to settle by changing very gradually.
To disable the maintained illuminance function completely, set the LUX level to maximum
9. Select the time out range using the adjuster, fully clockwise is the maximum.
10. The area of detection can be varied by altering the angle of the sensor head and the sensitivity
adjuster. Note: on maximum sensitivity this unit is extremely sensitive to movement and may
detect through glass, thin walls or partitions. If this causes a problem reduce the sensitivity by
turning the adjuster anticlockwise.
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 inside the unit. The UHS handset can also be used
to set the lux levels—see Section 9.5
Note: the above adjustments can also be made using the CRPHS handset instead of the
manual

When there is a requirement to have an ‗Off‘ state that requires a permanent dimmed level. Then use the
DSI / DALI ―pair‖ to both switch and dim, and a live feed direct to the ballast. Set the ‗Off value‘ (section
4.10 in the Programming section) to a value greater than zero to achieve a permanent dimmed level for
the ‗Off‘ state. See the diagram below for wiring details.
