6.3.4.5 Threshold LED color change
The viasis is supplied in several versions, with a numeric LED display with one or two LED
colors. Only the two color versions have a menu item for changing the LED display color de-
pendent of the measured vehicle speed. The color of the numeric speed display changes, for
example from yellow to red color, if a detected vehicle moves faster than the set “
Threshold
LED color change
” speed limit.
Also this option can be used to indicate the vehicle drivers that they drive too fast and their
vehicle speed exceeds the local speed limit.
The threshold is set like the other thresholds in the range from 5 km/h till 200 km/h (numeric
speed display color change deactivated).
6.3.5 Optimizing display
The viasis is equipped with a sensor for the environment brightness. With the measured values
the needed brightness of the display LEDs for a good visibility is calculated and controlled.
With the menu
Optimizing display
the LED display brightness can be influenced if needed:
Optimizing display
1. Operating time
2. Balanced
3. Visibility
Your choice 1...3?
If the option
Operating time
is chosen the display appears darker and reaches maximal 50% of
the possible brightness adjusted ex factory. If you choose
Visibility
the LED display appears to
be brighter in compare to the
Balanced
setting. Here the viasis reaches the adjusted maximal
brightness earlier and needs up to 50% more battery energy with the consequence of having a
reduced operating time with battery supply.
6.3.6 Menu extensions thresholds
The viasis can be equipped with several optional extensions, which can be divided in two
groups.
One group are the LED display extensions in form of LED warning symbols, which are inte-
grated in the numeric LED speed display field, which are shown alternating to the numeric
speed values, see chapter 6.3.6.1.
The other group consists of controlled switches as relays or power MOSFET transistors
switches or switched optical output units, like LED warning lamps, LED matrices with text or
symbols, which are activated additionally to the numeric LED speed display at the same time,
see also chapter 6.3.6.2 foll.
All switches or output units are activated by the excess of a set speed threshold by
the measured vehicle speed. More precisely an “on and an off speed threshold can
be set for each symbol, switch or peripheral device.
