Page 18: Configuration
7.4 Configuration For initial setup the MC-Balance controller needs to be configured in the CONFIGURATION menu once. Depending on the configuration, some settings will be invisible in case they are not relevant. Highlighted Parameters are factory settings. : ENG / DE... - Page 19 18-30VDC A tacho signal up to 30 Volt DC. This is used when the MC-Balance 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.
- Page 20 The maximum voltage that can be applied to the MC-Balance 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.
- Page 21 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.
- Page 22 IP-address for use in a network environment (TCP/IP protocol). (For example 192.168.001.001) When a MC-Balance is part of a network, the controller must have an IP-address for identification. This IP-address has to correspond with the IP-address of your computer. Ask your network administrator for a unique address.

Page 24: Loadcell Calibration
7.5 Loadcell calibration When using a MC-Balance for the first time do an initial load cell calibration as follows: The unit must be mounted horizontally (water leveled) • Avoid vibrations during the load cell calibration. This will influence the calibration. -
Page 25: Material Pre-Calibration
With a pre-calibration it is possible to calibrate the unit before production is started, in this way the time needed to come in spec. can be reduced. The MC-Balance is a gravimetric / loss in weight dosing unit. When starting up the dosing unit for a new production run there is no direct information available about the loss in weight. - Page 26 To clear the material description fill in spaces or select an empty material calibration out of the list. How can I delete or rename a calibrated material? To delete one or more material see chapter 7.13. To delete all Materials select master reset MATERIAL in the CONFIGURATIONS <menu> and confirm.

Page 32: Filling The Hopper
The controller automatically detects when the hopper is manual filled. In the period that the hopper is being filled, the MC-Balance is dosing with a fixed RPM, this means the unit runs temporarily volumetric. As soon as the hopper filling is ready, the MC-Balance immediately continues to work gravimetric. - Page 33 How the EX (support frame for External hopper loader) works The function of the support frame is to use an foreign hopper loader in combination with the MC-Balance. The support frame is equipped with a knife gate valve for filling the hopper. The valve is normally closed.
- Page 34 Open the hopper lid and fill the hopper by hand. (filling will be detected automatically) The message “Low hopper level” appears when the hopper is empty. (default 700 gr.

7.11 Consumption The consumption menu will be visible when an automatic filling system is selected and enabled in HOPPER LOADER <menu>. Without use of the optional Movacolor filling system, accurate working of the consumption registration is not supported. With the Consumption function it is possible to view the total quantity of material dosed by the MC- Balance. -

Page 41: System Performance
Extreme vibrations and shocks influence system performance noticeably. Normally the system will be able to compensate for vibrations and shocks. The MC-Balance algorithm needs a certain time to weigh material loss and adjust the RPM accordingly. This time depends largely on the set point and the above mentioned two variables. -
