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 unit 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: Powerswitch to set the machine on; thermal cut-out, mains voltage, thermistor protection lights; emergency button.

• Low noise
• Easily accessible and easy-to-use controls
• Easily replaceable vessels even with different diameters
• All main components are surface-mounted
• Easy access to the control unit, through back plate removal
