Product description
RDW Flash Lights (Optional)
Two relay outputs are provided on two 2-wire cables for connection to external RDW signal
lights on the left and right front of the truck.
If the truck is in lane, both RDW lights are illuminated continuously
If the truck is moving unintentionally too close to the left bund wall, only the right light is
illuminated. The left RDW light will not be illuminated anymore.
In case of unintentional read departure to the right (center of the lane), only the left
RDW light is illuminated. The right RDW light is not illuminated anymore. This informs
truck drivers in the opposite direction that the truck is leaving the lane.

Black Spot Warning
TPS provides a function to mark mine site areas with GPS positions. Each GPS position
defines a position in world coordinates with a circular area around it. This area is called
“black spot” (1). This function can be used for two purposes:
On mine site may be locations where the road departure warning system has no usable
roadside barrier as a side reference. These locations may be crossroads,
loading/unloading or construction areas. These areas may be marked by their positions,
disabling the RDW function in their vicinity and thus suppressing false warnings.
Also the position is used for “black spot” marking and identification. Black spots are
hazardous areas like intersections, construction areas, crushers and workshops. TPS
warns the operator when the truck is entering a black spot to raise operator’s attention.
If the black spot is activated for the area the truck is currently placed or driving, the GPS
position is stored and a black spot with the radius of 80m (by default) is created and
stored.
Inside black spot areas, the driver may also disable all acoustic warnings (2). Therefore,
the speaker-icon is shown while the truck is inside the black spot area. Pressing this icon
disables all sound output.
The sound output is automatically turned on again when leaving the black spot area. This
function may be used to mute TPS while the truck is in maintenance in a workshop.
Note that for the correct function of black spots, GPS must be available.
