In Valve management, you can enter:
➤
Current valve : Number of the valve/pump combination – this can be se-
lected using the Valve - and Valve + buttons.
➤
Impulses per litre : The output of the metering pump is calculated from the
electrical pulses of the volume counter or shaft encoder using the number
of pulses per litre (K factor). This factor is determined from the metering
pump output. The K factor has to be recalibrated from time to time by
volumetric measurement as the output of a metering pump declines with
increasing wear in operation (see section 5.5.2 on page 51).
➤
VOC share : Proportion of solvent in the materials used as a percentage
(VOC = Volatile Organic Compounds).
➤
Double stroke error : Minimum duration of an error-free double stroke, at
below which a corresponding alarm is to be output (approx. 700 ms).
Press the Save button to save your input.
5.5.8 Recipe management
The data for the valve/pump combination in use on the unit must be recorded
in Valve management before you can set up recipes.
Press the button in the Setup menu
shown on the left to open the Recipe
management input window.
Enter the following data to set up a
recipe:
➤
Current recipe : Recipe number
– this can be selected using the
Recipe – and buttons.
You can create up to 10 different
recipes.
➤
Designation : Recipe name.
Fig. 78: Recipe management
➤
Valve A : Number of the valve/pump combination through which the A com-
ponent used in the recipe will be delivered.
➤
Valve B : Number of the valve/pump combination through which the B com-
ponent used in the recipe will be delivered.
➤
Mixture A : B : Desired volumetric mixing ratio between the A and B com-
ponent. If the mixing ratio is defined by weights, you have to convert the
weights into volumes.
Volume = Weight
Density
Weight = Volume . Density
➤
Pot life : Pot life is the period in which the mixed material can be processed
from the time of it being mixed until the material increasingly cures.
➤
Controller tolerance : Permissible deviation from the desired mixing ratio.
The tolerance range is factory set to ± 3%. If the deviation is greater than
the pre-set tolerance, the controller intervenes to correct.
