Any use that is not in conformity with the instructions is considered improper and as such frees
the manufacturer from any liability regarding damage to things and/or persons.
Before switching on the unit for the first time, ensure that the mains power voltage
applied is between 80 and 260VAC.
Always switch off the Movacolor control cabinet and disconnect the mains power plug from
electrical power before performing maintenance.
Ensure that all parts are securely fixed to the extruder or injection molding machine.
Dangerous voltages are present inside the control cabinet for up to 2 minutes after it has been
switched off.

4Installation
Mechanical Installation
Most mechanical parts are pre-assembled, making installation quick and simple.
1. When installing a foreign main material hopper on top of a neckpiece, the top flange of the neckpiece
needs to be adapted. The lid of the neckpiece can be dismounted for easy machining.
2.
•Install the neckpiece directly on top of the
entrance of the production machine;
•Install the neckpiece in a 90-degree angle
to the machine barrel. This will optimize the
dosing accuracy in relation to vibrations of
the production machine;
•Make sure that the complete unit is mounted;
•horizontally levelled and fixed securely;
•Assure proper grounding to control cabinet,
neckpiece and dosing unit.
3. Connect the unit to the neckpiece by closing curled knob
clockwise.
Mount the unit in a 90-degree
angle to the machine barrel,
as shown in the picture.
Horizontally leveled (MCMicro
with 500ml hopper).

MC12 manual
Electrical Connections
The MC12-Micro controller is standard equipped with 3 connections:
1. Mains power cable,
2. Input cable
3. Motor cable
Before switching on the unit for the first time, ensure the mains power voltage being applied is between 80 and 260Vac.
Input (start) signal
The MC12-Micro needs an input signal from the production machine in order to operate.
Two different input signals can be used to control the dosing unit.
1. A potential free relay contact: Use the white and brown wire for the potential free contact.
2. A relay signal up to 24 Volt DC: Relay signals can be used for an extruder that has not a tacho signal. In
case of a powered relay signal connect the white wire to +24 VDC and the yellow wire to - side.
Also please have a look at APPENDIX B: MC12-Micro Wiring Diagram.

5Metering principle
The Dosing Cylinder® of Movacolor combined with a very
precise adjustable stepping motor ensures that the additive
output is accurate and regular. For every particular application
Movacolor provides different neckpieces but the most common
mounting of the neckpiece is between the production machine
and the hopper. In the figure below a cut through of the NST40
neckpiece can be seen.
During operation, the virgin material runs from the
machine hopper through the neckpiece (1) into the
machine. Inside the neckpiece the virgin material flow (4)
is divided into two streams by the cover plate(3). In the
space below the cover plate, the rotating cylinder (2) is
dosing additive.
Additive is added directly into the center of the virgin
material flow, just before it enters the production
machine (5). This is a great advantage over metering devices
that use batch pre-mixing because pre-mixing can
actually cause material separation. Separation of
materials results in an irregular additive flow into the
production machine.

6Operation
The Interface
General
•Connect motor before switching on the controller
•ALL changes has to be entered to acknowledge.
•A blinking value means the changed data is not acknowledged.
•To cancel a changed value, press the specific function button ( or ) again.
•Most functions have a designated key and LED on the interface. When a function is activated the LED
of that key/function will light up.
•All functions except the test function can be activated if the unit is started, (dependent on the
chosen configuration.)
•Only one of the following functions , , can be active at the same time. This means no other
function can be activated before the active function is deactivated
The unit can be set to different configurations, see paragraph 7.3.

MC12 manual
Start up
The MC12 software version is displayed shortly when the unit is switched on followed by the configuration
mode (con).
When the MC12 is set to configuration 2, the time function key is deactivated.
When a deactivated keys is pushed the unit will give a beeping signal.
For changing the unit configuration see paragraph 7.4.
Configuration
To make the configuration available,
keep speed and enter pressed while switching on the main power.
The configuration number will be displayed, press to switch between the possible configuration
and press to acknowledge. The software version will be displayed.
Timer
Timer mode is used for injection molding with a relay input signal. When the relay contact is made, the unit
will start dosing according the number of seconds that has been set with the time function.
Relay
A relay signal can be used in case working in extruder mode. With the relay input the unit will start dosing
when the relay contact is made and will stop when the relay is interrupted.
Speed and Timer
Speed and dosing time can be altered (time only in case of injection molding)
Speed = rotation of dosing system in RPM, (0,1 to 200 RPM)
Timer = time dosing system will rotate after start impulse, at input cable ( 0,1 to 999,9 sec)
Activate by pressing or , set the desired speed or time using press enter to
acknowledge

Production (Motor On/Off)
Press to start production. The function active LED will start blinking when the unit is waiting for an
input signal. The unit is dosing if the Start LED is lighted continuously.
Test (Material output), can only be used when unit is stopped
Test procedure to determine output of dosing system:
•Place dosing unit horizontally leveled (water level surface).
•Set the speed (and or) time (see settings)
•Press for Test
•Weigh the material dosed during test
•Adjust speed or time and repeat Test if necessary.
(Configuration 1): The unit will dose with the set speed and time.
(Configuration 2): The unit will dose for 30 seconds at the set speed
Emergency stop.
If the test is activated press stop to cancel a test.

7Maintenance
To keep the MC12-Micro functioning correctly, it is advised to perform regular maintenance.
Always switch off the control cabinet and disconnect the mains power plug from electrical power
before performing maintenance.
Weekly
•Clean the dosing tool (cylinder or auger) for proper operation;
•Check dosing tool (cylinder or auger) for wear out. The rubber coupling of a dosing cylinder is a typical
wear out part;
•Check the dosing cylinder bearing for smooth rotating.
Monthly
•Check the motor seal for abnormal wear out.

8System performance
The following variables may influence the accuracy and repeatability of the system:
1. Material properties. Easy flowing, non-sticky and non-static material that comes in the form of small
regular shaped granules or powder can be dosed very accurate and regular.
2. Periodical cleaning of the dosing cylinder and seals is necessary for proper operation.
3. Extreme vibrations and shocks can have negative influence on system performance.
4. An unstable relay signal has a negative influence on the repeatability.
5. With injection molding the shot to shot accuracy depends, besides the variables mentioned so far, on
the shot time in combination with granule size and weight. If relatively big and heavy granules have to
be dosed in a very short time, it will influence the shot accuracy and repeatability, because if only a
few granules are dosed during the shot, one granule more or less makes a big difference on the total
shot weight.
6. Vacuum or overpressure in the neckpiece caused by driers or hopper loaders.
7. Bridging or rat holing of the material inside the hopper can happen if the material is not free flowing.
8. Bridging or rat holing of the material inside the hopper can happen if the material is extremely static.
9. Extremely static material can contaminate the dosing cylinder.
10. In case of water cooled neckpiece, check if there is material build up around the dosing cylinder and
the water cooled pipe. Check also the water supply to the neckpiece.
