Chapter 5: ARGUS
5.1 ARGUS movement detector, surface-mounted
INSTABUS ARGUS 220 Connect
Art. no. 6315 ..
Version 03/04 8
Setting the brightness
The brightness threshold can be infinitely adjusted in a
range between approx. 3 lux and 1000 lux. In daytime
operation (sun symbol), the ARGUS switches after
each movement, regardless of the external brightness.
In night operation (moon symbol), it only reacts below
3 lux (darkness).
Setting the time
This makes it possible to set the overshoot time of the
connected loads. This is the time period from the last
detected movement until the load is switched off. De-
pending on the ETS application, the overshoot time is
either set in the ETS program (infinitely between
3 seconds and 152 seconds) or directly on the ARGUS
(six steps of approx. 1 second to approx. 8 minutes).
|
Once the load has been switched on, the set
brightness threshold is ignored. Depending on
the settings in ETS, each registered movement
can reset the overshoot time. If the movement
detector no longer switches off, it is probably
because it is continually detecting new move-
ments and is thus always extending the
overshoot time.
Masking out individual areas
Using the four inserts supplied, you can shield unwan-
ted zones and sources of interference from the area of
detection.
1 Place the inserts exactly on those areas of the sen-
sor head which should be masked from detection.
2 Ensure that the brightness sensor (A) is not cove-
red as the sensitivity to light is otherwise reduced.
