Pre-Set Cut-Off
Prior to the dispenser reaching its preset amount, the solenoids are
switched to give a low flow rate. The “preset cut-off” sets the amount (in
litres), prior to the preset amount being attained, at which the solenoids will
switch to a low flow rate.
With the value set to 0.00, the default values are used. These are:
 LPG 0.75
 Oil 0.05
 Other products 0.32
The Preset Cut-off is calculated as follows:
[Price per Litre] X [over-run (displayed as a dollar value)] + default value as
above.
Example:
Price per Litre = $0.96
Dollar amount of fuel required = $20.00
After delivery price display shows: $20.01 ($0.01 is the over-run dollar
value)
New preset = (0.96 x 0.01) + 0.32 (Other Products) = 0.3296
0.3296 rounded up = 0.33
New preset cut-off to be entered is 0.33.
Setting the Pre-Set Cut-Off
Refer to C4000 Set-Up K Factor Switch Settings (see page 21) The Price
display shows 'PCut' and the volume display shows 'PCX.XX'. The range is
