SLOW DOWN SYSTEM

HARDWARE | SLOW DOWN SYSTEM

In order to conform to safety standards most karting venues already adopt a series of basic preventive measures, such as mandatory helmet and protections mounted on the vehicle and on the track.
These are certainly essential precautions, which however have little or scarce impact on the factor that more than any other can bring about risky situations, namely the ability of the pilot to always keep his vehicle under control.
The most effective solution is not so much as to further restrain rental karts performances, since they are already very limited as compared to competition karts, but rather to provide equipment designed to adjust and limit the speed of all karts on the track in real time.

SHUTDOWN SYSTEM

The system we recommend is highly reliable and is designed to perfectly fit on four strokes engines. It combines two distinct devices that can be  easily installed  and used:

  • a shutdown transponder to be connected to the spark plug (for internal combustion engine karts) or to the coil (for electric engine karts) directly powered by the engine;
  • a remote control by which the track manager can control and adjust the vehicles speed when needed.

The two devices constantly interact, since the shutdown transponder detects the engine’s RPM/relais status  and sends the data to the remote control; this in turn enables the track manager to  regulate  each single  kart’s speed through its transponder, typically when improper or dangerous driving is involved. You have just to select the code of the kart you want to slow down and reset its max. speed. Once the penalty is over,   the speed limitation is taken away automatically. Dedicated buttons on the keyboard allow for quick speed adjustments even on selected groups or on all karts simultaneously, for instance when emergency operations have to be  carried out.

XTRA SECTOR CONTROL

By means of the Xtra Sector Control System the karts speed can be controlled in every section of the track. When an accident occurs the speed of the karts driving inside the dangerous zone is automatically limited and once the karts get outside the dangerous section, the speed limit is released.

The same system can be used for speed control. Once a kart drives into the pit area, the speed is automatically reduced while the other karts on the track retain their normal speed. When a kart exits the pits, the speed is set to normal.

As a further safety feature we suggest to adopt the Xtra Sector Control system on each section of the track where  accidents  are more likely to take place, typically  the pit-in / pit-out area or dangerous chicanes. In the first case the system automatically reduces the speed of the kart which is driving into the pit area, while all the other vehicles retain their speed, while iIn the second case case, when an accident occurs the speed of all the karts driving within  the dangerous sector will be   limited.

The Xtra.Sector Control System consists of one or more beacons placed along the track and a   sector  sensor  mounted on every kart connected to the Xtra.Shutdown transponder by means of the kart network port.

A loopwire, which will mark the sector starting point, is then   placed across the tarmac   and connected to the beacon.  Once the kart passes the loop the system automatically limits the speed according to the selected settings.
