Delivery and accessories
The xing screws and the terminal for connecting to the
KNX bus are included in the supply of the device. This
must be completed with a plastic adapter, a plate and
eventually a frame (all have to be ordered separately).
Finishing plate
The sensor is completed with an ekinex®plate in metal or
Fenix NTM®material. The plate must have (at least) a 50
x 50 mm window in combination with a plastic adapter for
‘NF, Deep or Surface series mounting.

Operation
The sensor reacts to the thermal radiation emitted by mo-
ving bodies. A person walking in the detection area across
the sections triggers the sensor.
The measurement of the room brightness is carried out by
an integrated light sensor; the brightness value, measu-
red in Lux, can be transmitted on the bus.
The internal brightness sensor can also be used to main-
tain a constant ambient brightness if a dimmable light
source is available.
Frame
The device is completed with a square ekinex®frame of
the form or ank series in metal or Fenix NTM®material.
The ‘NF (No Frame) versions, on the other hand, must be
mounted without a frame.

Switching, display and detection elements
The device is equipped with 2 switching elements, loca-
ted under the cover:
• a KNX programming button (1)
• a switch to select the operating mode Manual / ON /
OFF (2)
The following signaling and detection elements are also
visible through the lens:

3) Signalling and programming LED
The lighting channels have two operation modes, Auto-
matic or Semi-automatic:
• the automatic mode controls both switch-on and switch-
o󰀨, when a movement is detected;
• the semi-automatic mode requires manual switch-on,
which is maintained until movement is detected; it will
swich-o󰀨 only when no more movement is detected.
In automatic mode, a load connected to a lighting channel
will be switched on when movement is detected and (if
desired) the ambient light level is below a preset bright-
ness value.
When no movement has been detected for a program-
mable time duration, a stand-by phase can be entered,
during which the light can be dimmed to a lower intensity.
The HVAC channels act in a similar way as the Light Con-
trol channels, but with neither the standby time nor the
dependence from the light level.
Positioning
The actual detection range of the sensors depends on the
mounting height. It is recommended to install the device
at a height of 1.2 m - 2.0 m. The detection range is 9 m
at a height of 1.2 m - 1.5 m and up to 8 m at a height of
1.8 m - 2.0 m.

Mounting
The device has an IP20 degree of protection and is the-
refore suitable for use in dry indoor environments. The
device can be assembled on a round or square box.
To assemble the device, carry out the following opera-
tions:
• insert the plastic adapter (c) on the device (d);
• insert the bus terminal, previously connected to the bus
cable (see: “Connecting to the KNX bus network”), in
the appropriate seat on the back of the sensor;
• x the adapter-device assembly (c+d) by means of the
pair of screws (e) on the ush-mount wall box (a) with
suitable holes, possibly inserting (if applicable) the fra-
me (b) between the box and the adapter;
• snap-t the plate (f).
The optimal range is achieved walking through several
portions of the detection area.
Since the detector responds to temperature change, be
aware that the following conditions may cause lower sen-
sitivity:
• In very foggy days, the sensitivity may be less due to
moisture collecting on the lens.
• In very hot days, the sensitivity may be less since high
ambient temperature is close to body temperature.
• In very cold days when heavy clothing is worn, espe-
cially if the facial area is covered, very little heat will
be emitted from the body causing the unit to be less
sensitive.
Please also verify following conditions during installation:
• Avoid pointing the detector toward objects with highly
reective surfaces, such as mirrors, glass, etc.
• Avoid mounting the detector very close to heat sources,
such as heating vents, air conditioners, lights, etc.
• Avoid pointing the detector toward objects which may
sway in air currents, such as curtains, tall plants, etc.
The direction of movement a󰀨ects the sensitivity of the
detection.

Limitazione of the detection area
The detection area can be limited, in order to avoid
unwanted activations, by means of the supplied optical
shielding lters. The shield consists of three layers, each
divided into four units, capable of masking an angle of
approx. 50 ° each.
When mounting the device at a height of 1.2 m - 1.5 m,
the detection range is:
• Layer A: masks the area with a circle from about 0m
to 9m.
• Layer B: masks the area with a circle from about 0m
to 3m.
• Layer C: masks the area with a circle from about 0m
to 1m.

minal block included in delivery and inserted into the slot
of the housing.
Bus
KNX
The connection procedure is as follows:
• strip the KNX bus cables with the appropriate tool (not
included in the supply), exposing about 5-6 mm);
• nish the end with the clamp
• connect the device to the bus cable terminated by the
standard terminal block on the back of the device.
At this point it is recommended to carry out the commis-
sioning of the device (see “Commissioning”), or at least
the download of the physical address, using the program-
ming button placed close to the bus connector.
Please check the user manual for further details on instal-
lation and commissioning.
Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP, EK-AG1-TP or EK-AM1-TP). The use of other
power supplies can compromise the communica-
tion and damage the devices connected to the bus.

tomatically returns to normal mode; during the program-
ming process, the programming LED is turned o󰀨. Now
the device is programmed and ready for use.
Conguration and commissioning
Conguration and commissioning of the device require
the use of the ETS®(Engineering Tool Software) program
V4 or later releases. These activities must be carried out
according to the design of the building automation sy-
stem done by a qualied planner. For the conguration
of the device parameters the corresponding application
program or the whole ekinex®product database must be
loaded in the ETS program. For detailed information on
conguration options, refer to the application manual of
the device available on the website www.ekinex.com.
Important: After a download, it takes approxima-
tely 60 s for the sensor to stabilize before it enters
normal operation mode. During this settling period,
the sensor may not appear to react or perform its
programmed functions.
i
Warning! Do not mount on conductive surfa-
ce. Do not open the enclosure frequently. The
sensor is a low voltage circuit; never connect it
with the 230V line network. Do not run the KNX
wiring in the same conduit used by line network
wiring.
