3.5.3 MCHybrid
The dosing algorithm of the MCHybrid is a self-learning algorithm. The system adopts automatically to the
material flow characteristics.
Together with the default dosing characteristics related to the mounted and configured dosing valve, the
system is able to learn and dose within 10% of its set point within about 3 batches.
During system start up the material flow characteristics are unknown, to avoid overloading of the weighing
bin the self-learning algorithm starts at 50% of the configured batch weight. As soon the material flow
characteristics have been determined, 100% of the configured batch weight will be dosed.
When the dosing accuracy cannot be met, a notification will arise mentioning the wrong dosing valve is used
or configured.
Extreme vibrations and shocks influence system performance noticeably. Normally the system will be able to
compensate for vibrations and shocks.
Changing set points during dosing of a batch will be adopted the next batch.
Periodical cleaning of the dosing valves, weigh bin and mixer is necessary for proper operation.
Reset regulation
• Reloading the material file resets the actual learned material flow characteristics;
• Switching the power OF and ON again will cause a total reset of the regulation.
