Foil 17
Activation of the „Brushes“ function causes lowering of the brush head to the so-called
central position. The lifting element does not attain the lower limit position before
cleaning with increased ground pressure. The brush head lifting element thus has 3
micro-switches integrated, one each for the upper, the central and the lower limit
position.
Extracting the side brush unit is possible only after the brush head had lowered or in
other words: if the central position micro-
switch does not switch, the „brush lowering
completed“ signal is missing and the side brush does not swing out. This signal
depends on the central position micro-switch only such that swinging out of side brush
is possible as well for cleaning with increased brush ground pressure. Since on its way
down to the lower limit position the central position micro-switch had been triggered
even if no fault occurred during cleaning with increased ground pressure.
