The parameters above are:
Volume
The volume to be dispensed at each filling. Please note that to avoid
overfilling the first dispense (before calibrating) will be approximately 80% of
the requested filling.
Tube The tube number (1 to 10) used selected from the tube table. The tube table
is specific for the pump type and can be downloaded from the pump
controller (please see next section). The tube table for each pump type is
found in appendix 2 in this manual.
Speed The revolutions per minute of the pump. If the product is foaming the
revolutions may have to be lowered. The speed range is 30 to 600; however,
the upper value is dependent on the pump type and the selected tube size.
Please see the details in appendix 2.
Acceleration A number indicating the ramp up and down when starting/stopping the
dispensing. The range is 1 to 200 rpm/s. The upper value is dependent on
the pump type and the selected tube size.
Reverse A number indicating the reversing of the pump after dispensing to avoid
dripping of the product between dispensing. The reverse is a number in the
range 0 to 10. The physical reversing is dependent on the pump type. For a
PD12 the value 10 gives ¼ reverse rotation where for a PD22 the value 10
gives a full reverse rotation.
Density The density of the product to use when calibrating. When calibrating the
weight of the filled amount of the product is entered. If the product has a
density other than 1 the MC100 has to take that into the calculation of the
pump data for filling to convert to volume. The density must be in the range
0,5 to 2,0 g/cm
3
. Please note the conversion to integer as described above.
Calibration value The weight of the product in g filled (found by subtracting the weight of the
vial from the total weight of the filled vial). When receiving the weight MC100
calculates new pump parameters for the actual pump and send it to the pump
controller. The pump will use the new setting from the first dispensing after
having received the new data.
If the volume is changed the calibration is reset. To avoid overfilling the
fillings after entering a new volume will be approximately 70 – 80% of the
requested filling volume. Hereafter a new calibration must be made.
Please note that if the calibration value is outside the limits (below 50% or
above 200% of the volume) a warning is generated and the calibration value
is ignored.
When transmitting and receiving the value for calibration please note the
conversion to integer as described above.
Please consult the manual for the actual pump type for a more detailed description of the parameters.
