6.7 Description of functions
The individual functions will be described in the following:
6.7.1. Function 1 -Volume
Value: Choice of ml and grams as unit.
Function 1 informs the system of the volume to be filled.
Value Option Related Function(s)
Min Max
0.01 9999.9 ml. or gram 72
The entered value must be between 0.01 and 9999.9. If a value outside these limits is entered,
the MC12 will correct the value to the nearest value within the limits and ask for acceptance via
.
When a volume is entered, the system will calculate the new parameter value which will then be
used from the start of the next fill. At the same time, the status line will be updated.
For an individual fill only the parameter value for the drive in question will be changed.
For parallel or serial filling, the volume should be entered in drive 0 and the parameter value will
be calculated for all connected drives.
6.7.2. Function 2 - Tube diameter
Value: Inside diameter of the tube in mm.
Drive type Tube inside diameter in mm
PD12P 0.5 0.8 1.2 1.6 3.2 4.8 6.0 8.0
Enter the tube diameter used. The MC12 will only accept original Flexicon tube diameters.
The diameters are specified in the manual for the drive and can be read on the tube gauge
supplied with the drive.
As most of Flexicons drives are of the peristaltic type and work with tubes, the system must know
the current tube diameter.
When programming a drive that does not use tubes as pumping element, this function will not be
activated.
The tubes should be indicated by their inside diameter and from these data the MC12 will
calculate how many revolutions the selected pump head should make in order to dispense the
required volume.
If an unrecognised tube diameter is entered for the selected drive, the MC12 will not accept this
diameter but will instead ask for a tube diameter from the original Flexicon range.
