Typical Cycle

The following table describes a typical hydraulic cycle.
Operator Action
Lift the nozzle
Nozzle lever opened.
Nozzle lever closed and nozzle
is hung up.
Function
These show the pressure of the supply pumps. Ensure the
biodiesel gauge is always 2 psi higher than the diesel
gauge.
Measure the flow of biodiesel and diesel.
Fuel is passed through these before being dispensed.
Provide on/off flow control for both diesel and biodiesel.
What happens at the dispenser
The C4000 activates the pumps. The solenoids open and
the fill commences.
Diesel is continuously dispensed, and the biodiesel
solenoid pulses on and off to ensure the correct blend
ratio is delivered. Fuel flow is metered.
After 10 litres is dispensed, the blend ratio is checked,
and then continuously monitored. If an incorrect ratio is
being dispensed an error will occur.
The solenoids close and the pumps stop after the fill has
ended.
