Vertical sunlight penetration
The optical element
provides greater pro-
tection from vertical
sunlight penetration.
SSP 192/105
Vertically incident sunlight is screened by the
car’s roof.
The optical element deflects less light onto the
photodiode. Cooling can be reduced as the
car’s occupants are not directly exposed to
heat radiation.
Effects of signal failure
No replacement function.
Self-diagnosis fault message
Open circuit/short circuit to positive.

Diagonal sunlight penetration
SSP 192/092
Particularly sunlight incident on the car’s
occupants diagonally from the front, i.e.
directly, increases the feeling of warmth.
The optical element deflects a large proportion
of diagonally penetrating sunlight onto the
photodiode. Cooling is increased to equalise
the effect of heat radiation on the body.
