Control system: 

• Electric cabinet: used to house low-voltage electrical parts such as frequency converters;
• Manual operation panel: used to place buttons, knobs, instruments, etc;
• Power supply: AC 3 x 380V±5%, 50Hz;
• Control mode: electric control + hydraulic control;
• Power control and speed regulation mode: inverter start and control;
• Cooling method: air cooling and liquid cooling;
• Operation mode: touch screen operation;
• Digital temperature display table: material temperature;
• Emergency stop button: one alarm system: overtemperature alarm, overtemperature alarm stop, alarm close;
• Speed display: The touch screen displays the speed;
• Power indicator: one;
• Timer: one that controls both dispersion and agitation;
• Note: If you select the HMI system configuration, the control system related content is integrated into the touch screen control.

Safety interlocking system:

• Scram: After you press the SCram switch, the device stops immediately and no operation can be performed;
• Start mixing at low speed. Mixing: you can turn while lifting the bucket;
• High speed dispersion: the barrel can be turned only when it is raised into position;
• Safety lock in operation: when the machine is running and mixing, the mixing barrel cannot be lowered or opened;
• Prevent vacuum pipeline backflow: Special vacuum buffer tank design, can effectively prevent the vacuum pump oil backflow into the mixing tank phenomenon;
• Operation failure stop: inverter comes with overload, overcurrent, overvoltage, leakage, lack of equal protection;
• Stirring bucket lift: The stirring bucket can be lifted only after it is in place;
• No vacuum is discharged in the mixing bucket (no normal pressure is restored);
• The high speed dispersion can only be started after the stirring bucket is lifted into place;
• After the mixing drum is raised in place, it is equipped with a locking protection system to prevent the mixing drum from falling abnormally after rising to a high level during work;
• The dry mixing stage requires the stirring paddle to rotate while lifting the barrel.
