Type Of Alt. Fuel Level Indicator - A.E.B. AEB215 Manuel D'utilisation

VEHICLE CONFIGURATION
TYPE OF ALT. FUEL LEVEL INDICATOR (Fig. 15)
Indicates to the LEONARDO E.C.U. the type of GAS level sensor that is utlilized on the vehicle.
A.E.B.
Select this option if any A.E.B. type L.P.G. or C.N.G. sensor (either
"optic" or "resistor" type) is used.
0-90 OHM
Select this option for any L.P.G. sensor with a variable resistance
from 0 Ohm (empty) to 90 Ohm (full).
NON STANDARD (Fig. 16)
Select this option if an L.P.G. or C.N.G. resistor type sensor with a
DIRECT variable signal (ohmmic value) is used. This value must be
low on empty and high on full.
NON STANDARD INVERTED
Select this option if an L.P.G. or C.N.G. resistor type sensor with an
inverted variable signal (ohmmic value) is used. This value must be
high on empty and low on full.
In a case where the "NON STANDARD" resistor type sensor is used, it
is necessary to verify first of all if the signal is DIRECT or INVERTED.
To this end, it is necessary to access the second page of DATA
DISPLAY (Fig. 17) and read the LEVEL readout.
If with a full tank the value of LEVEL is high (about 200), the sensor
is of the DIRECT type, thus "NON STANDARD" must be entered.
If the value of LEVEL is low (about 10), the sensor is INVERTED, thus
"NON STANDARD INVERTED" must be entered.
After the above has been established, it is necessary to enter the
correct references for LOW, 1/4, 2/4, 3/4, and full by proceeding as
follows:
- have pen and paper ready;
- move the sensor's indicator manually, starting form the full position
and writing the corresponding number for each reference mark (EMPTY,
LOW, 1/4, etc.);
- enter the values that have been noted in the corresponding areas
by means of the hand-held tester.
FULL TANK LEVEL = value of LEVEL with a full tank; the four GREEN
LED's are on.
3/4 REFERENCE = value of LEVEL when the 4/4 led goes out.
2/4 REFERENCE = value of LEVEL when the 3/4 led goes out.
1/4 REFERENCE = value of LEVEL when the 2/4 led goes out.
LOW REFERENCE (example in Fig. 14) = value of LEVEL when the
low fuel led is on and the 1/4 led goes out.
VALUE FOR EMPTY TANK = value of LEVEL with an empty tank.
These parameters are displayed only if "NON STANDARD" or "NON
STANDARD INVERTED" sensor is selected.
ONLY LOW FUEL SENSOR TYPE (Fig. 19)
Select this option if a sensor with the exclusive function of indicating
low fuel for L.P.G. or C.N.G. is used.
