1. USE
This microwave presence detector provides automatic control of
lighting loads with optional manual control.
It 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 and turns the load on. When an area is
no longer occupied, the load will switch off after an adjustable timeout
period.
These units come complete with accessories allowing flush mounting in
suspended ceilings or surface mounting on ceilings, or side mounting
on a luminaire.
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.
The flexibility of having two output channels and two switch inputs
allows the following example scenarios:
− Dimming an outside row of luminaires whilst internal fittings
are switched
− Providing absence detection for two separate channels
− Installing a maintained illuminance system with manual
override controls for dimming
This detector has an adjustable sensor head that allows the detection
area to be optimised for the application.
All functionality is fully programmable using an infrared configurator.

4. CONNECTION
Channel 1 (switched output) can either be used to switch a set of
luminaires, or to isolate the mains supply of DALI/DSI dimming ballasts
(saving on the standby consumption of the ballasts).
Multiple loads can be connected in parallel as long as the maximum
total load is not exceeded.
Channel 2 (dimmable output) can be used to dim DALI/DSI ballasts or
dimming transformers.
The ballasts/transformers can be connected in parallel as long as the
maximum number is not exceeded.
The wiring examples below show common installations using this
detector.

6. OPERATION
Detection mode
Presence: When movement is detected, the load will automatically
switch on. When an area is no longer occupied, the load will switch off
automatically after an adjustable time period.
Absence: The load is manually switched on. When an area is no longer
occupied, the load will switch off automatically after the adjustable time
period has elapsed.
In either case, Presence/Absence, sensitivity to movement of the PIR
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.

Regulation according to light level
The detector measures the overall light level in the detection area, then
calculates and dims the luminaire lighting to achieve a preset Lux level
(maintained lighting 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 data sheet for more details).
Operation - By setting the “Burn-in” parameter, you can select a time
during which the lamps are not allowed to deviate from maximum
dimming. 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.
7. SETTINGS
The detector functions are controlled by a number of parameters which
can be changed or programmed by an infrared configurator.
In combination with configuration tool 0 882 40, the Legrand Close
Up smartphone app can be used to view and modify all the detector
parameters with online help.
Point the infrared configuration tool at the detector for all read/write
operations.
Valid commands will be indicated by a red flashing LED on the product,
and the lighting switches off automatically for all read/write operations.
Before changing the settings, an initialisation operation must be
performed as suggested in the Legrand Close Up configuration app:
1 - Click on “Scan product settings”
2 - Click on “Settings details/copy”
3 - In the menu at the top right (…) select “Initialise”
4 - Click on “Write product settings”
This operation allows predefined setting of certain parameters.

General parameters
LED operation
test Off - ON or Off When this option is activated, a red LED on the sensor flashes when it detects movement. Use this function to check that the sensitivity levels are suitable.
Inhibit
detection No - Yes/No
Disables presence/absence detection so that the detector does not control
switching, only dimming. Use this mode for light regulation without automatic
control according to occupancy.
Timeout 20 minutes -0 to 99
minutes
Once the detector is turned on, this value sets how long the lights will stay on once
movement has ceased. Select 0 for a 10-second period (for commissioning only).
Manual timeout
period 10 minutes -0 to 99 minutes
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. When the user leaves the room, they press the Off
button. The sensor will revert to automatic mode after 3 minutes. Walking back into
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 if it doesn’t pick up anything over a short period,
the detector will revert to automatic mode. This means that the lights may come on
inadvertently during the presentation, even if the occupants are still present during
the manual timeout period, so adjust the timing carefully.
On sensitivity 8 9 1 (min)
to 9 (max) Sensitivity level for detecting movement when the detector is already on.
Off sensitivity 8 9 1 (min)
to 9 (max) Sensitivity level for detecting movement when the detector is off.
On delay 0 minutes -0 to 99
minutes
The On delay allows the first channel to switch on after the second channel.
Atypical application for this would be when 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 before the detector times out, then the air conditioning will not
have come on. The delay can be set for channel 1 only using this parameter.
Detection mode Presence - Presence
or absence
Presence mode allows the output to turn on when movement is detected and
off when movement ceases. Absence mode allows the output to turn off when
movement ceases, but must be manually turned on first.

General parameters (continued)
Lux Off level 999 225 1-950,
999: disabled
Sets a maximum light level above which the PIR sensor is disabled, preventing the
lights from being turned on by movement.
Lux On time 0 - 0 to 99
minutes
When the ambient light drops below the Lux On Level, this is the delay before
the lights come on. If at any time during the timed delay the Lux level position
is reversed, the process is cancelled. A minimum time of 15 seconds is defined
for a value of 0. If you try to turn on the lights using a manual control, the lights
will come on regardless of the ambient light level. However, if there is sufficient
ambient light, they will turn off again after the Lux Off time.
Lux Off time 0 1 0 to 99
minutes
When the ambient light exceeds the Lux Off Level, this is the delay before the lights
go out. If at any time during the timed delay the Lux level position is reversed, the
process is cancelled. A minimum time of approximately 15 seconds is defined for
a value of 0.

output will toggle between this value and completely off depending on the switch
level On and Off values. For example, if it is light outside, the fittings will be off if
there is no occupancy. If it is dark outside, they will adopt the preset off value. This
feature is only enabled if “Min value” is set to 99.

8. TROUBLESHOOTING
1. If the load does not switch on
- Check that the live supply to the circuit is correct.
- Check that the load is functioning by bypassing the detector (link terminals L and L/Out).
- If the detection range is smaller than expected, see the Performance section. Rotating the sensor slightly may improve the detection range.
2. If the load does not switch off
- Ensure that the area is left unoccupied for longer than the timeout period.
- Ensure that the detector is not affected by circulating air, heaters or lamps.
3. In the event of“false tripping”, reduce the sensitivity settings.
4. If the light level is often too low
- Increase and adjust the value of the “Lux level for regulation”parameter: from 150 up to 200.
- Adjust the value of the following parameters:
• Lux On Level = Lux level for regulation - 5
• Lux Off Level = Lux level for regulation x 1.5
Example:
- Lux level for regulation = 180
- Lux On level = 175
- Lux Off level = 270
- Lux Off time = 1
- Min value: 82%
5. If the lighting loads never switch off (minimal lighting)
• Reduce and adjust the value of the “Lux Off level”parameter” in steps of 10 or 20
Example:
- Lux level for regulation = 150
- Lux On level = 145
- Lux Off level = 215
- Lux Off time = 1
- Min value: 82%
6. If the light level is too high
- Reduce and adjust the value of the “Lux level for regulation”parameter.
- Adjust the value of the following parameters:
• Lux On Level = Lux level for regulation - 5
• Lux Off Level = Lux level for regulation x 1.5
Example:
- Lux level for regulation = 130
- Lux On level = 125
- Lux Off level = 195
- Lux Off time = 1
- Min value: 82%
