2 Product description
The ekinex
®
p esence detecto is a KNX S-mode device fo the indoo detection of occupancy and
movement of people, with an effective detection ange of 360° thanks to its th ee passive inf a ed (PIR)
senso s.
The detection ange can be fu the extended by employing mo e ekinex
®
p esence detecto devices as slave
units. Two channels C1 and C2 a e available fo the lighting function; these can be used to achieve a
constant b ightness cont ol by using C2 as an offset input espective to C1 (f om -50% to +50%).
The light intensity in constant b ightness cont ol is measu ed by the integ ated b ightness senso ; its value is
made available fo bus t ansmission in Lux units (2 byte). An o ientation light function can be p og ammed
with a standby value (in %) and a du ation value (in minutes o hou s).
The channel dedicated to HVAC applications allows the independent cont ol of te minal devices dedicated to
Heating, Ventilation and Ai -Conditioning.
The device is equipped with an integ ated bus communication module and is designed fo ceiling flush
mounting. Seve al ve sions a e available which diffe in the detection ange and in the lens and f ame type.
The device powe supply is taken f om the KNX bus and no auxilia y powe supply is equi ed.
2.1 Versions
The device is available in fou ve sions which diffe in the detection ange (eithe 16 o 30 m) and the f ame
shape ( ound o squa e).

2.3 Operation
The p esence detecto eacts to the the mal adiation emitted by moving bodies. A pe son that c osses the
monito ed a ea automatically activates the lighting. As soon as the senso does no longe detect any
movement, a delay is sta ted (whose du ation is configu ed th ough ETS) afte which the lighting is switched
off.
If the standby mode is active, the lighting is maintained at a lowe b ightness level as an o ientation light fo
the length of the configu ed standby time.
2.4 Light intensity measurement
The ambient light intensity is measu ed by an integ ated b ightness senso having a linea output p ofile and
an additional filte matched to the human visual sensitivity.
The light senso is capable of sending a bina y teleg am (On o Off) to signal a light intensity level which is
highe o lowe than a configu ed th eshold value, ega dless to the ope ation mode. The measu ed
b ightness level in Lux units can fu the be t ansmitted on the KNX bus.
2.5 Lighting channel
Two ope ating modes can be chosen fo the lighting channel du ing the configu ation phase:
•fully automatic
•semi-automatic
The fully automatic mode has th ee diffe ent states, i.e. ready, active and passive, whe eas the semi-
automatic mode only has the ready and active states. In semi-automatic mode, the lighting is not activated
afte the detection of a movement, but only afte p essing an exte nal pushbutton.
2.6 HVAC Channel
The HVAC channel has the same ope ating modes and communication objects as the lighting channel; the
detection of movement and p esence is enhanced though, int oducing the “long du ation” p inciple. The
detection is based on seve al time windows (f om 2 up to 20) of equal width; in eve y one of these windows
at least one movement must be detected in o de to yield a positive esponse.

3 Configuration
The ope ation of the device is defined th ough the softwa e-configu ed settings.
In o de to configu e the device, the ETS3 softwa e tool (o late ve sions) is equi ed, togethe with the
ekinex
®
application p og am APEKSP2TP##.vd4 (## stands fo the ve sion numbe ). This latte can be
downloaded f om the ekinex website www.ekinex.com.
Please note that the configu ation p og am is exactly the same fo all fou device types which a e subject
of this manual; as a matte of fact, as can also be seen f om section 2.2 (Scope of Supply), the code used
in the p og am name is the code of the “ba e” device, and the diffe ence betwees the fou device types lies
enti ely in the kind of pa ts assembled on the ba e device.
The application p og am allows the use to access, within the envi onment of the ETS configu ation tool, the
configu ation of all of the device’s wo king pa amete s. The application p og am file must be loaded in ETS
(optionally the enti e database of all ekinex p oducts can be loaded in one single step); the eafte , any
numbe of devices of the co esponding types can be added to the cu ent ETS p oject.
The configu able pa amete s fo the device a e desc ibed in detail in the following sections.
The configu ation can (and usually will) be defined enti ely in an off-line fashion, i.e. without being connected
to a device o a KNX netwo k; the t ansfe of the configu ation to the device(s) will the efo e happen in a late
phase (the p og amming phase, desc ibed in the following section).

4 Commissioning
Afte the device has been configu ed within the ETS p oject acco ding to use equi ements, the
commissioning of the device equi es the following activities:
•elect ically connect the device, as desc ibed in the p oduct datasheet, to the bus line on the final
netwo k o th ough a pu posely setup netwo k fo p og amming;
•apply powe to the bus;
•switch the device ope ation to p og amming mode by p essing the p og amming pushbutton located
on the ea side of the housing. In this mode of ope ation, the p og amming LED is tu ned on steady;
•upload the configu ation (including the physical add ess) to the device with the ETS p og am.
At the end of the upload, the ope ation of the device automatically etu ns to no mal mode; in this mode the
p og amming LED is tu ned off. Now the device is p og ammed and eady fo use on the bus.

5.5 Brightness
Pa amete s:
Brightness
This menu allows to set the pa amete s fo the output communication objects 8 (B ightness th eshold
switch value – Switch, 1 bit) and 9 (B ightness value – Lux, 2 bytes).
Transmission of the lux
value in case of change of This pa amete enables the t ansmission of the b ightness value, i.e.
communication object 9, eve y time the selected th eshold (see pa amete
Brightness value threshold for switching) is exceeded by the specified value.
Available values ange f om 10 Lux to 1800 Lux o OFF.
Please notice that this value is the variation respective to the threshold
value.
The default value is 100 Lux.
Cyclical transmission of the
lux value Available values ange f om 5 s to 30 min o OFF.
The default value is OFF.
Brightness value threshold
for switching Available values ange f om 10 Lux to 2000 Lux o OFF.
The default value is 300 Lux.
Hysteresis Available values ange f om 5 Lux to 200 Lux o OFF.
The default value is 30 Lux.
Object value for ON Selects which value of the switch communication object 8 co esponds to
the active state of the th eshold compa ation.
Available values a e ON o OFF.
The default value is ON.
Object value for OFF Selects which value of the switch communication object 8 co esponds to
the inactive state of the th eshold compa ation.
Available values a e ON o OFF.
The default value is OFF.
Transmission filter Selects which state changes fo the th eshold activation t igge the
t ansmission of the switch communication object 8.
Available values a e: ON and OFF; neither ON nor OFF; only ON; only OFF.
The default value is ON e OFF.

AD calibration value* In o de to co ectly set this pa amete , the AD calib ation value
(communication object 10) should be ead th ough ETS, and the value
should be input in this field.
Warning. In the ETS G oup Monito , when eading o sending this value, the
Data Point Type 7.001 pulses 2-byte counter, unsigned) should be used.
The value ead f om the AD will appea in the “Received value:” field as e.g.
