MC-Balance manual 16
Configuration: Control mode
(GRAVI) Gravimetric mode or (RPM) Rotating mode
•
Gravimetric mode is set as default and operates on the base of loss-in-weight principle.
The output is measured and regulated continuously by controlling the motor speed.
•
Volumetric mode (RPM) can be used if no automatic feedback of the weight is required.
The weighing will not function in this mode and also the automatic hopper loader function will
not work.
Configuration: Prod. mode
Production mode
Selection of the machine on which the MC-Balance is placed.
(EXT) extruder or (INJ) injection molding
Configuration: Input mode
Type of input signal. Relay, Timer or Tacho
Timer mode is the standard setting for Injection molding.
Input mode is not visible in RPM prod. Mode. (Timer is used automatically)
For INJ in timer mode the start pulse should be min. 0,2 seconds.
For INJ in relay mode the start signal should be as long as the dosing time.
If INJ-Relay is selected the dosing machine will follow the machine relay time.
The controller will filter small changes out so that the regulation is not being influenced.
Big changes will be followed.
The screen shows the real machine relay time.
Input (start) signal
The MC-Balance needs an input signal from the production machine in order to operate.
Three different input signals can be used to control the MC-Balance.
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 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. It will function as a
start signal. Connect green to + VDC and yellow to the - side of the generator.
