For the programming of tube diameter the individual drive is selected via Function 41 and the
tube diameter is entered under Function 2. In this way, the last drive may for instance fill a smaller
part of the total volume than the other drives in the system. This is done by applying a smaller
tube in the last drive.
When all drives have been programmed, the MC12 will automatically calculate which part of the
total volume the individual drives should fill, so that they are completed simultaneously.
This gives the best capacity.
Calibration is also carried out in drive 0, as the system perceives the whole system as one
single drive.
Functions 8 and 10 will be calculated on the basis of completed fills from the last drive and
Function 11 will be calculated on the basis of all drives.
6.7.31. Function 41 - Select filler (drive)
If several pumps are connected, this function is used for selecting the number of the filler to be
shown on the display and to be controlled via the keyboard.
Function 41 selects the drive to be programmed and shown on the display. The current drive
number is always shown in the top right hand corner of the display.
Press: <4>+<1>+, and display shows: “ENTER DRIVE NO.:”
The drive number required for the new drive can now be entered, followed by . The
system will then show the new current drive in the display indicating the new number in the top
right hand corner. If a drive number is entered which is not connected, the system will correct the
number to the lowest number representing a connected drive.
Drive 0
Drive 0 does not exist physically. Drive 0 is used as the current drive when the system works in
the parallel or serial mode.
Drive 0 in individual mode
Drive 0 is not used in this mode as all drives work with different parameters and applications.
Drive 0 in parallel mode
The following parameters are identical for all drives in the parallel mode and they are
consequently programmed in drive 0:
F 1: Volume F 2: Tube diameter
F 3: Velocity F 4: Acceleration/deceleration
F 5: Reversing F 6: Batch size
F 7: Delay F17: Timer 1
F18: Timer 2 F19: Timer 3
