CHOICE OF 

FUEL FLOAT

CHOICE OF FUEL FLOAT. 

The control unit is programmed for a float with rheostat, suitable for 

FUEL LEVEL indication.

MANAGEMENT OF FUEL W

It is possible to program the use of a 

float with contact that closes to     

 

ground when there is no fuel.

PROGRAMMING OF OHMIC VALUES OF FUEL FLOAT

It is possible to program 10 resistive values, 

corresponding to the characteristic curves 

of other floats.

WARNING

:  It is necessary to program

 

at least 2 values (to obtain good 

 

precision in the control of the fuel, we

 

recommend programming at least 4 values).

 

If just one value is programmed or 

 

non-monotone values are programmed, the   

 

fault is detected
