FUNCTIONS
All electronic controls and warning devices are placed on the disperser Control Panel. The hydraulic-operated lifting distributor is located on the machine body: it must be operated together with the ON switch of the hydraulic control panel motor on the Disperser control panel.
The Control Panel also includes: the potentiometer for stirring shaft speed adjustment, digital rev-counter with display, the ON - OFF -RESET push-buttons for Inverter and EMERGENCY button control.
The Switch board with the Inverter features the following controls:
- Power switch to set the machine on
- thermal cut-out, mains voltage, thermistor protection lights
- emergency button
OPERATION AND MAINTENANCE
- Low energy consumption: power consumption depends on the power actually supplied by the Inverter by setting the power-knob
- Low noise
- Easily accessible and easy-to-use controls
- Easily replaceable vessels even with different diameters
- All main components are surface-mounted. Access to pulleys and belts by removing upper
- metal-plated lid of the machine head
- Easy access to the power unit, through back plate removal
- Inside column lubrication unit on external bearing column.
ALTERNATIVE VERSIONS
