MC-Balance manual 18
Manual
:
Fill in the voltage the tacho produced by the tacho generator at maximum extruder speed.
Automatic
:
Let the extruder run and select Set tacho:
YES
.
The tacho voltage P1 will be taken over automatically and is linked to the set motor speed P2 (in
RPM mode) or calculated motor speed (in GRAVI mode)
During production, the motor speed P2 can be changed. The new speed is linked to the previous
stored voltage and the graph will change accordingly.
During production, the voltage P1 can be adjusted to the current tacho input voltage (manually or
automatically) as shown above. The new voltage is linked to the previous stored speed and the
graph will change accordingly.
-The maximum voltage that can be applied to the MC-Balance is 30 VDC.
-The tacho signal must be a clear signal. Any failure in the voltage signal will be followed by
dosing variations.
Configuration: Fill. System
Filling system, NO(None), ME, MV or EX (see chapter 7.10)
Configuration: Filling start
Function: When it is detected that the hopper is running empty the filling system will switch on.
The filling system will start loading when the weight in the hopper is 800 grams (default) or less.
The default value can be changed manual if necessary (depending on the material properties).
Also with EX hopper loader selected this is the weight level for opening the knife gate valve to fill
the hopper.
Only visible when a filling system is selected.
Configuration: EX-H level
The filling knife gate valve will close if the weight in the hopper is 2500 grams (default) or more.
Only visible if EX (External / foreign) hopper loader is selected.
Configuration: EX-HH level
HH level is High level warning. If the weight in the hopper reaches 3000 grams (default) or more a
warning will be given.
Only visible if EX (External / foreign) hopper loader is selected.
Configuration: Hopper empty
The system will give an “Low hopper level” message if there is less then 700 (default) grams of
material in the hopper. For this system to work correctly it is necessary that the load cell calibration
is done with an empty hopper and the hopper lid in place. This system will always be active.
The default value can be changed manual if necessary (depending on the material properties).
See also chapter 7.12 for how to set this message to alarm or warning.
