Fig 72.
A float sensor is fitted to the fuel tank to measure the level
of fuel in the tank. A magnetic float rises up a tube
containing a series of 5 ohm resistors with switches in
parallel. The fuel level is displayed to the operator by
means of a bar graph gauge. The actual values can be
displayed via the EMS SET+MODE menu. Both the actual
value and bar graph values should be an average of
consecutive readings to provide a degree of dampening to
prevent false readings
Text warnings are provide for both reserve fuel and low fuel
conditions. Low fuel is also backed up by a flashing bar
graph.
The low fuel condition must be present for one consecutive
minute before the "LOW FUEL" warning is displayed.
The reserve fuel condition must be present for one
consecutive minute before the "RES FUEL" warning is
displayed.
