If an appropriate software is installed in a computer, it is possible to connect oneself,
through the serial interface, to the "VOILA PLUS" panel box thus allowing modification of
various parameters and function display.
With the Tester it is possible to display :
- stepper motor position through a three figure display.
- Lambda feeler position.
The change over switch is not included in the "VOILA PLUS" package, IT HAS TO
BE BOUGHT SEPARATELY.
The connection to the BLUE wire of the change over switch (GAS exit service) is
necessary for the activation of the "VOILA PLUS" only during GAS operation. During the
PETROL operation, all connections will be reset as from starting point.
The stepper motor has the task of adjusting the GAS flow inducted by the engine while
keeping carburetion within optimum values, in every working condition. To do so, the "VOILA
PLUS" panel box elaborates the T.P.S., Lambda Feeler and Rev motors signals.

T.P.S. is mechanically connected to the throttle valve, and sends a voltage signal to the
injection panel box that varies in proportion with the throttle opening angle. "VOILA PLUS"
uses the same information for the GAS carburetion control.
- T.P.S. is LINEAR TYPE when voltage, depending on change of throttle position,
gradually increases or decreases .
- T.P.S. is SWITCH TYPE when the voltage goes from minimum to maximum or vice versa
no sooner the accelerator is slightly pressed.
- T.P.S. of a MONOBOSCH has the potentiometer throttle with two signal wires that are
different from each other. Select the MONOBOSCH function only if you are connected to
wire N. 2. It is recommended, nevertheless, connecting wire N. 4 as well.
- The panel box can work even if the T.P.S. is not present, it is however
recommended to connect this wire whenever possible.
