Digital speed limiter with brake lever code and automatic reactivation

Digital calculation and control of speed and rpm

Function:

The digital speed limiter (DZB) is equipped with a powerful microprocessor that continuously calculates and analyses the speed and rpm.

Determining the speed:

• The speed is determined by the wheel sensor supplied together with a small self-adhesive magnet for the rim.
• The speed is calculated directly through the CDI ignition pick-up cable at each piston revolution.

Operating mode:

KMH Mode:

• In KMH mode, a maximum speed limit is set.
• The DZB accelerates the scooter by reducing the speed as soon as this limit is reached.
• A variably adjustable pre-stage allows for a gradual reduction in speed just before maximum speed, for a smooth transition.
• Below the set maximum speed, the speed remains unchanged.

Speed ​​Mode:

• The wheel sensor is not needed in speed mode.
• The DZB regulates the scooter only through the adjustable maximum speed.
• If the speed drops below the set limit, the DZB does not intervene to prevent a loss of power in the lower speed range.

Combined mode:

• The DZB operates simultaneously at the set RPM and KMH limit.
• Especially useful when a high-revving scooter needs to be set to a low top speed.

Programming and control:

Programming the maximum speed is done simply by pressing the internal programming button.

Deactivation:

• To deactivate the accelerator, a 6-digit Morse code is entered using the brake lever.
• To reactivate it, simply briefly turn the ignition off and on again.

Dimensions and installation:

• The DZB housing is compact (45x45x18 mm + mounting eyelet).
• The connecting cables are 45-50 cm long.
• The wheel sensor has dimensions of approximately 28x19 mm, with a cable length of approximately 50 cm.
• Installation is easy thanks to 4 quick cable connectors.
• Installation requires connecting +12V (switched via the ignition lock), brake signal, pickup signal and ground/minus.
• In KMH mode, the wheel sensor and wheel magnet must also be connected to the front or rear wheel.

The advantages in summary:

• Digital speed and rpm control
• Continuous programming
• Adjustable pre-stages for a smooth transition
• No power reduction below top speed in KMH mode
• No power reduction in the lower speed range in speed mode
• Automatic activation of limitation
• Deactivation of the brake lever via code
• Individually adjustable brake lever code
• Quick cable connector for easy installation
• Optimal workmanship for longer life

Supply and compatibility:

The scope of delivery includes the KMH rev limiter, 4 quick connectors, the wheel sensor with self-adhesive wheel magnet and detailed step-by-step installation instructions.

The DZB is compatible with most 2-stroke carbureted motorcycles (e.g. CPI and Keeway with Minarelli replica (1E40QMB)), but does not work with 4-stroke motorcycles, direct injection motorcycles, Morini engines and motorcycles with double pick-up.
