Speed regulator H version, for A-tractor construction without high rpm to drive in 30

Speed controller, D version for e.g. diesel engines, engines with multiple ignition coils or
if you want to measure and break speed instead of speed.
However, the D version does not contain all the functions required for A -tractor, see the H version for this.

Connects to the generator output for tachometer or to inductive sensor* on drive shaft or speedometer output on gearbox
Controls the valve for fuel injection to the engine (diesel), or supply to ignition coils.
Setting is done in the same way as our other regulators.
Can be used to drive supply voltage to ignition coils in the cars that have 3 ,4 or 6 ignition coils, e.g.
Can be used with inductive sensor on drive shaft to measure and break speed instead of engine speed.
Can be used with speed signal from digital speedometer signal found on some Volvos.

This version works in the same way as other speed regulators, but is adapted for, among other things, diesel engines. Setting takes place by holding a number of revolutions and pressing a button. Then the speed is stored in a memory and when the cut-off speed is exceeded, the output that controls the fuel injection valve (or supply voltage to the ignition coils) is affected.

The yellow cable (speed regulator input) is connected to the generator output for the tachometer, or other signal whose frequency depends on the rpm/speed. The blue wire (speed controller output) connects to the electric solenoid that opens/closes the fuel supply to the engine. The output has a powerful driver and gives +12V output in normal mode, and 0V output when the break-in speed is exceeded.

The +12V that normally goes to the solenoid valve can instead be used as a +12V supply to the speed regulator (red cable). The blue cable from the speed controller is connected to the solenoid valve. The pictures are from a D24 Volvo engine.

Break on speed instead of RPM?

By measuring speed, let the RPM controller break on speed, you get the advantage that you can rev the engine freely and independently of which gear is in. You can measure by mounting a sensor* on the gimbal and connecting it to the D version's yellow cable. If you have a digital speedometer signal, you can use it and connect it to the regulator. On the Volvo 240, for example, there is a speedometer output on the gimbal from approx. model year 1986.

* Inductive sensor can be our product 03-185 or signal for the speedometer (however, it must be digital with a signal level between 0 and 5V- 12V). Unfortunately, it does not work with signals from standard ABS sensors, they have too weak a signal.

This model is also available with a shiftlight function< /strong>
Shiftlight is an addition to the speed controller in the form of a blue LED (diam 10mm). It lights up just before the set breaking speed is reached. It thus indicates "the breaking speed will soon be reached" and it is easier to stay within the desired speed.
