The MC-TC needs an input signal from the production machine in order to operate.
Three different input signals can be used to control the MC-TC.
1.) A potential free relay contact.
Use the white and brown wire for the potential free contact.
2.) A relay signal 24 Volt DC*.
In case of a powered relay signal connect the white wire to +24 VDC and the yellow wire to
the 0 VDC.
* Note potential contact
Guaranteed OFF: 0-8VDC
Guaranteed ON: 18-30VDC
3.) A tacho signal up to 30 Volt DC.
This is used when the dosing system needs to be connected to an extruder that has a tacho
generator that produces a voltage linear to the extruder speed. When using a tacho
generator signal, make a connection between the white and brown wire. It will function as a
start signal. Connect green to + VDC and yellow to the - side of the generator.
The maximum voltage that can be applied to the MC-TC is 30 VDC. The tacho voltage has to be
reduced to 30 VDC if the tacho generator has a higher voltage output than 30 VDC at the
maximum extruder output capacity. See the diagram below.
Rx (kilo-Ohm) = (2,684 x (Max. tacho output VDC –5)) –66
If the extruder stops when connected to the metering unit, an isolated signal converter is needed.
Contact your agent or Movacolor for more information.
Tacho function
The tacho function is only available in extrusion mode.
This function can be used with extrusion when it is necessary that the dosing rate is automatically
adjusted to the extruder speed. In tacho mode an input voltage is linked to a dosing speed setting.
If the extruder speed changes, the tacho input voltage and speed of the dosing unit will change
accordingly.
A linear correlation between extruder speed (tacho input signal) and the needed dosing speed is
assumed. See graph.
The tacho function can be set in the PRODUCTION screen.

Tacho can be set manually or be synchonized:
Manual:
Fill in the voltage the tacho produced by the tacho generator at maximum extruder speed.
Synchronize:
Let the extruder run and select synchronize.
The tacho voltage P1 will be taken over automatically, enter the actual extruder capacity. This 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-TC tacho input is 30 VDC.
-The tacho signal must be a clear signal. Any failure in the voltage signal will be followed by
dosing variations.

3.4 Material curves
3.4.1 Offline Material curve learn function
Each material has its own flowing characteristic. This results in a material curve which is used for
accurate volumetric dosing. During system start, when there is not enough measurement info
available, the dosing system uses this curve. The speed of the dosing tool is then adjusted
according to the learned curve. Using a pre-calibration results in a faster system start, the system
will operate faster within the set specification.
The material curve learn function can be performed offline, to avoid waste of material. To do so,
slide the unit backwards and use a cup to gather the dosed powder.
1) Unit with option slide frame:
Slide the frame with unit backwards till the “click”
Before starting the material curve learn function, be sure that:
during calibration the dosing unit is horizontally fixed and also vibration free.
the correct dosing tool is mounted.
the hopper is filled with sufficient material.
the loadcell cable is connected to the controller.
the loadcell is calibrated.
The following parameters will be stored with a Material calibration, depending on the configuration:
CONFIGURATION parameters: Cylinder type : type of dosing cylinder or feed screw
Material Type : Normal or micro-granules
PRODUCTION parameters: Shotwth. : Shot weight
color% : Color amount (%)
dos.time : Dosing time (sec)
Ext. cap. : Extruder capacity (kg/h)
CALIBRATION parameters: Material name: Name of calibrated material
How to start the material curve learn function:
1. Press
In multicomponent setups it can be necessary to use the button to select the unit to be used.
2. Press the material “name” button and enter a material description.
3. Enter the production settings, recommended is to use the same settings as will be used in
the final production.
For injection molding:
the shotweight
the dosing time
dosing percentage

MC-TC manual
13
For extrusion:
extruder capacity (production rate)
dosing percentage
The ideal situation is to choose the same settings as used during actual production, however when the output is to high and learn
function cannot be completed within one hopper fillen, choose a lower capacity.
4. Press the start button
5. A question will appear that you need to check if the motor is connected, the hopper is filled
and if you want to prime the dosing tool, confirm the question.
6. The learning will take minimal about 3 minutes but can take more time depending on the
used material and production parameters.
It is possible to stop during the learning (for example to refill the hopper). When
“Stop&Save” is selected the learning will pause. There are 3 options:
= Stop learning and save the collected data.
= Stop learning without saving.
= Continue with learning.
7. The unit will execute the calibration procedure, the procedure will stop when the dosing is
within the calibration deviation range (default 5%), the material curve will be stored. This
material is now automatically selected for the current unit.
During the calibration the unit is regulating to his Setpoint. When this point is reached the
calibration will be saved automatically. On the basis of this point a complete curve is made on
bases of default pre-programmed curves.
