The HMI (Human/Machine Interface) Control Panel is connected to the microprocessor and is used to operate the unit and

The HMI control panel has a display and eight touch sensitive keys.
The display is capable of showing both text and graphics.
The keys on the left and right sides of the display are dedicated or single function keys. These are termed “hard” keys.
The four keys under the display are termed “soft” keys. The functions of these keys change depending on the operation being
performed. If a soft key is active the current key function is shown in the display directly above the key.
