6.7.5. Function 5 - Reversing (back suction)
Value: An integral number.
When the filling stops, the filler can be asked to produce a small back suction to prevent
dripping.
The back suction can be set at values between 0 and 10.
0 = no back suction
10 = maximum back suction.
The value has no relation to any other parameters and is solely a number of degrees of a rotor
turn. Consequently, the volume that is sucked back will depend on the tube diameter.
If a value outside the range between 0 and 10 is entered, the MC12 will automatically correct the
value to the closest value allowed and the operator has to accept it by pressing the
If the value of the parameter is changed during a fill, the new value will not be applied until the
start of the next fill.
6.7.6. Function 6 - Batch size
Value: Number.
Enter the number of fillings you want the filler to perform when started by
electrical signal.
There is a choice between 1 and 65,000.
When the filler is operating in an automatic system, where the system itself starts the filler each
time a bottle is in position, the value in this function must always be 1.
If a value outside the range between 1 and 65,000 is entered, the MC12 will automatically
correct the value to the closest value allowed and the operator has to accept it by pressing the
The value in Function 6 will only be active during filling, and after each fill the drive will wait for the
time delay specified in Function 7 before the next fill is started.
When the system has completed the number of fills entered in Function 6, the system will stop
and wait for a new
again carry out the number of fills entered in Function 6.
For filling in individual mode, the batch size should be entered for each single drive. For fills in
parallel or serial mode, the batch size should be entered in drive 0.
