1. Detector functions
The sensIQ S PIR presence detector comprises a passive infrared
(PIR) motion detector with integrated light-level sensor, integrated IR
receiver and integrated red light-emitting diode (LED) for indicating
a movement detected. The detector is capable of performing the
following functions:
1.1 Functions:
- Light output - lighting is switched ON and OFF in relation to
ambient brightness including basic light level function,
- Presence output - switching response irrespective of ambient
brightness,
- Close-up range output - signals detection in the close-up range,
- Photoelectric lighting controller,
- Light level measured.
The function to be used (activated) is defi ned by the "General
Settings" parameter window using the ETS3.f version of the
Engineering Tool Software (ETS) and higher.
Each of the detector functions provides the capability of setting a
period after which a detected movement is to result in activation of
the function concerned, of defi ning when the function concerned is
to be deactivated again after detecting the last movement and of
defi ning any light level from which the function is to be activated or
deactivated.
1.2 Light output:
When the light output is used for controlling lighting, it is switched
ON as soon as anyone enters the detection zone after darkfall but
only OFF again some time after the last person leaves the detection
zone. If a person returns to the detection zone shortly after leaving
it, the area is still illuminated, saving the need to switch the light
back ON again. "Stay-ON time" is set to a fi xed period. The soft-
start function allows you to choose the option of switching light ON
and OFF abruptly or of selecting "soft start" which is particularly
pleasant on the human eye as light is switched ON and OFF across
a dimming ramp. A further setting is provided in the form of the
basic light level function. As soon as ambient brightness falls below
the defi ned threshold, a basic level of lighting is switched ON and
can be dimmed to between 10 and 50%.
1.3 Presence output
This function watches over the detection zone. A signal is sent out
as soon as a person's presence has been reliably detected. A signal
is also sent out as soon as the presence of persons is no longer
being detected.
This surveillance function can, for example, be disabled during the
day and only enabled for a specifi c duration at night as well as over
the weekend.
1.4 Close-up range output:
You can only use this function for watching over the close-up
range near the sensor and operate further actuators in relation to
movement detected in the close-up range.
1.5 Photoelectric lighting controller:
The photoelectric lighting controller defi nes a light level threshold
(independently of the light output) at which an actuator is switched
ON irrespective of detected movement when ambient brightness
falls below this defi ned light level. This means that several lights can
be switched ON at dusk, with further lights then being switched ON
via the light output when movement is detected.
1.6 Light level measured:
The light level measured function emits the level of light currently
being measured at the motion detector's light level sensor either
after light level changes by a defi ned minimum amount and/or
cyclically after a defi ned interval.

2. IR remote control
The sensIQ S comes with an IR remote control for setting various
functions. Manual override (duration ON/OFF), holiday function,
light level by teach-IN (function learns current light level) and reset.
3. Test mode
The motion detector's "lighting test mode"can be switched ON and
OFF by means of the ETS.
"Lighting test mode" is used for testing reach. Lighting is switched
ON in response to any movement detected and regardless of
ambient brightness. To do this, the detector must have been
parameterised by ETS and its objects linked with the objects of the
buttons and actuators for lighting control.
In the lighting test mode, the red light-emitting diode integrated
in the presence detector briefl y fl ashed to indicate any movement
detected. In addition, the lighting stay-ON time is set to 8 s for the
duration of this test mode irrespective of the parameters selected
for the presence detector. No other function is active.
4. Behaviour after bus voltage fails and returns as
well as on re-starting and downloading
In the event of bus voltage failure, the motion detector also ceases
to operate as its electronic system is powered by the bus voltage.
Before bus voltage failure, all user entries are saved (light level
setting, stay-ON time, photoelectric lighting controller setting,
remote-control code, all disable statuses, all night lengths) so they
can be restored automatically when bus voltage returns after bus
voltage failure.
After bus voltage returns and after completely or partially uploading
the product database to the presence detector by ETS (i.e. after
re-starting) , the motion detector is disabled for approx. 40 seconds.
Lighting is switched ON at the start of disabling time and switched
OFF for approx. 2 seconds at the end of disabling time. From
then on, the detector is ready for operation and sends the latest
telegrams (outputs, light, presence, close-up range, photoelectric
lighting controller and light level measured) if the relevant outputs
were not disabled before bus voltage failed.
5. Behaviour after initial start-up and unloading
When installing a brand-new motion detector, it automatically goes
into "presence test mode" as soon as the bus voltage is applied.
In this mode, the red LED integrated in the motion detector fl ashes
to indicate any movement detected. This shows that bus voltage
is being applied to the detector and that it is in working order.
However, light-level control is deactivated and no telegrams can
be sent.
If the presence detector's calibration programme is "unloaded" by
ETS, the presence detector automatically goes into "presence test
mode" in just the same way as it does after initial start-up.
