Lifting each nozzle opens the switch which is indicated
by a 1 on the associated digit.
INPUT 2
1 up to 5
REAR Nozzle Switches
Lifting each nozzle opens the switch which is indicated
by a 1 on the associated digit.
INPUT 4

12.15 Checking Input Status
When in Stack Test press the
f
key again to display the available stack input groups.
The digits in each group relate to the following inputs:
Key Points
1. The motor must be on and the valves open to set flow
rates. Press
5
to store the current setting for fast flow.
2. The number in the top row of the price window (
A or B
)
is the valve percentage.
C
3. The numbers in the bottom row (
B
and
C
) are front and rear flow rates.
4. Pressing
3
and
9
will open both front and rear valves allowing them to be set
at the same time.
5. Where there is high flow diesel the flow rate must be set for each hose individually.
Ensure the flow rate does not exceed the nameplate Qmax value. The valve % must
be set and saved to limit the flow to less than the Qmax.
6. Higher flow rates are not necessarily better. A flow rate of 30 – 38 L/min is optimal.
40 L/min or greater will likely cause the nozzle to trip with tight filler necks.
7. A change of 1 - 2% can affect flow rates by several litres per minute.
