Presence detectors

(incl. brightness sensors)

Mounting guidelines for presence detectors

■

Make sure that the workplace is right in the detection

zone of the presence detector – without any obstacles

such as shelves, plants, glass walls, etc. blocking the

detector

■

Keep in mind that moving machines, plants and animals

in the detection zone will be interpreted as movement

■

Avoid sources of rapid changes in temperature or light,

such as fans, incandescent or halogen lamps; air ﬂows

and light in the detection zone simulate movement

■

Mount at least 50 cm away from cables and radiators

Mounting guidelines for presence detectors with

brightness sensors

■

Avoid light sources that switch on or off, such as TVs,

in the detection zone; they simulate movement

■

Avoid light sources with a high infrared component;

they distort the daylight measurement

■

Make sure that the brightness sensor measures only

indirect, reﬂected light; direct sunlight distorts the

measurement results

■

Avoid shiny surfaces that are highly reﬂective

■

Keep in mind that thermal protection glass can inﬂu-

ence the daylight measurement; the tripping value

will be lower
