Open Loop
Working principle
In open loop configuration the amount of dosing of the color unit is adjusted to the level of regrind dosed by
the regrind unit, regrind is fed to the system by either a ME, EX, MFD or 3PH hopper loader or knife gate
when using a MCHigh Output.
If at system start no regrind is available (hopper weight below EMPTY level), the regrind unit will not start
dosing. The color unit will dose it’s nominal %. To start the regrind unit, manual activation of the loader
system is required.
The loading system will now. Be able to start while the system is switched off!
When during production no regrind is available, the unit will give an alarm. As soon as the regrind material
hopper is below EMPTY level, the regrind unit will stop dosing. The color unit dosing amount will increase to
nominal to maintain color level. To restart the regrind dosing, the manual activation of the loader system is
required.
