Dispense not correct (too much)

To much material has been dispensed so there is nothing the controller can do. Of course the relations within the recipe will corrected by re-calculations.

After the first dispense try in all of the above mentioned cases a new dispense rate will

be calculated. If the measured dispenserate (measured weight / dispense time) differs from the used dispenserate a correction can be made. A correction is only made if the difference between the measured- and used dipenserate is less then the boundary (dispenseRateVarBand). This method prevents the controller calculating incorrect values e.g. if a hopper runs out of material. The new dispenserate is calculated by the next algorithm:

dispenseRate = ((4 * dispenseRate) + (measuredWeight/dispenseTime))/5

When all components of a recipe are dispensed the contents of the weighbin is dumped in to the mixer chamber. The weighbin dumps the material by opening a valve for a given time. This time (weighbinDumpTime) is a parameter which can be changed. It is also possible to start the mixer at this time (see mixer-mode). There are two conditions for opening the weighbin valve:

Condition 1. The mixbin-vale may not be open (if present)

Dispensed material must be mixed first before it can be used. Therefore the mixbin-valve and weighbin-valve may not be open at the same time.

Condition 2. The mixerchamber may not be full

If the input-device indicates a full mixerchamber no material may be dumped into it (it is full)

2.7.7Calculations

In order to be able to dispense with high accuracy, the actual measured weights will be used to recalculate the requested weight of the next component. The dispense will be optimised if possible in order to guarantee a good batch (good relation).

IMPORTANT

Best dispense order is:

Regrind, Natural, Additive
