Fuel filter (4) is made up of a filtering cartridge with water
separator, inside which electronic unit (6) is housed.
Water accumulation capacity is equal to 140 cm3.
Electronic unit (6) includes water present sensor, (optional)
filter clogging sensor and temperature sensor.
Water present sensor
Water present sensor detects water present in the filter
starting from 110 cm
sensor provides values of:
- low voltage in presence of water;
- high voltage in absence of water.
Characteristics
12V nominal voltage (8V minimum -16V maximum)
Absorbed current:
- lower than 15 mA in rest conditions;
- lower than 150 mA in alarm conditions (including load).
Voltage on load:
- in rest conditions: higher than 11.8 V;
- in alarm conditions: lower than 3.9 V.
At key-on operation, the sensor makes a self-test issuing 2.5
second duration sound signal.
