Mounting height
There is a rule of thumb: place the sensor at least as
high above the monitored Door Clear zone as the
intended width / depth of the active Door Clear
zone. Example: The active Door Clear zone should
top the optical axis by 50 mm to the left and to the
right. To cover the entire zone width (up to 100
mm), the sensor must be placed 100 mm above the
upper edge of the active Door Clear zone.
In the DC configurator, configure the corresponding
distance on the z-plane (e.g. 500 - 1800 mm), see
Fig. 14.
The opening angle of the sensor´s field
of view α is approx.:
• 40° in entry and exit direction
and
•
50° parallel to the direction of
travel.
Sensor to door, walls and
floor distance
Place the sensor at a distance of 5 to max. 20 cm
from the door to avoid false status messages due to
reflections from the glass and a DC zone that
extends too far into the room.
Strong reflections from walls or floors can cause
the sensor to detect interfering objects within the
configured Door Clear zone. Leave a distance of at
least 200 mm between the configured Door Clear
zone and the floor or the reflecting walls. 
Avoidance of false, “not clear” door status
messages.
• The increased distance between
door and sensor reduces
malfunctions caused, for example,
by glass reflections.
• Occasionally, IRMA MATRIX distance
measurements show a fault
tolerance, which is caused by
different light conditions, specimen
and series scattering, aging etc.
Movable door elements
The configured Door Clear zone must not contain
any movable door elements. Non-static objects in
the surrounding area visible to the sensor are not
likely to be regarded as “background”. Therefore,
measure exactly the space between movable door
elements and enter the x and y values in the Config
Tool (mm), then click APPLY.
• A door element entering the
monitored detection zone triggers a
“not clear” status.  Prevents the
door from closing
Assessment of the surrounding area
with a side effect
An object permanently located in the sensor´s field
of view in the function area is regarded as part of
the surrounding area. The time it takes for an
object to fuse with the sensor-internal background
• Luggage located in the active Door
Clear zone, which leads, for
example, to an “not clear” status
