6.7.11. Function 11 - Accumulated volume
Value: Litre
Nothing can be entered in this function, as it only displays the total volume used since the latest
reset of the function.
To reset this function, press the key.
The value of this function is updated at the completion of each fill.
If the value of accumulated volume is less than 1,000 litres, it will be displayed with 3 decimals. If
the value is equal to or more than 1,000 litres, it will be displayed with one decimal.
6.7.12. Function 12 - Maximum flow
Value: Volume per time unit.
Nothing can be entered in this function as it only displays the current maximum flow.
The read-out is based on the flow created when the rotor runs at the required velocity.
The function reads out how much liquid the system pumps through the tubes per time unit. This
unit can be changed in Function 71. See the information about Function 71.
The read-out will be updated immediately after changing the value in Function 2 or Function 3.
6.7.13. Function 16 - Pumping direction
Value: Clockwise or counter-clockwise.
As not all drives can work with more than one pumping direction, this function will only be active
when connected to a drive with that option e.g. GD30I.
Start by entering: <1>+<6>+ and display shows: “DIRECTION (1/2):”
1 = CLOCKWISE ROTATION
= product from top of pump
2 = COUNTER-CLOCKWISE ROTATION = product from side of pump
Thick creams require a feed hopper mounted on top of the pump and consequently, pumping
direction 1 is used.
For products which flow more freely and can be drawn up against gravity e.g. shampoo, the
suction tube is mounted on the side of the pump and consequently, pumping direction 2 is used.
Select the wanted value and press
6.7.14. Function 17 - Timer 1 (Disabled in FMB version)
Value: Seconds.
