7 Programming
7.1 Programming principle
In the following, a parameter will be the value of a single function, i.e. volume, tube diameter
or velocity. A program will be a complete set of parameters which together will constitute the
PD12 work instructions.
The actual programming will be made on the MC12 and reference is made to the MC12
manual.
7.2 PD12 parameters
1. Volume
Value: ml
Range:
0.01 – 9999,9 ml. ml
PD12 can dispense from 0,1 to 9999 ml, but for volumes exceeding approx. 250 ml, the
capacity might not be adequate.
If the volume is changed, a recalibration should be made.
2. Tubes
Value: Inside diameter (i.d.) in mm
Range:
0.5 - 0.8 - 1.6 - 3.2 - 4.8 - 6.0 - 8.0.
If the tube is changed, a new calibration must always be made.
3. Velocity
Value: Revolutions per minute (rpm)
Range: :
30 - 400 rpm for tubing above Ø1.6 id.
30 - 500 rpm for Ø3.2 id. tubing.
30 - 600 rpm for tubing smaller than til Ø1.6 id.
If the velocity is changed, a recalibration should be made.
4. Acceleration/deceleration
Value: An integral number
Range:
1 – 100 for tubing larger than Ø3.2 id.
1 – 150 for Ø3.2 id. tubing
1 – 200 for tubing up to Ø1.6 id.
The acceleration and the deceleration will always be the same.
The lowest value (1) will give the slowest acceleration.
The highest value (200) will give the fastest acceleration.
If the acceleration is changed, a recalibration should be made.
5. Reversing (back suction)
Value: An integral number
Range: 0 - 10
If the rotor is moved a little backwards (reversing) after the completion of fillings, a minor
back suction will be created. This can prevent dripping from the filling needle.
The value "0" will give no reversing, but the value "10" will give maximum reversing.
ALWAYS make a recalibration if the reversing value is altered.
For other programming possibilities, reference is made to the MC12 manual.
