User interface

The on-board Human Machine Interface (HMI) consists of a Liquid Crystal Display (LCD) and keypad. The HMI can be used to
obtain feedback from the local push button operations and as a configuration tool. The display screen is dot matrix and the
menu system is driven with the 4-button keypad. Changes can also be made to transmitter parameters via MODBUS
communications. Go to Appendix C, MODBUS
During normal operation, the operation screen (Figure 9) provides current values and operational information from the
transmitter.
HMI keypad
The local LCD display (Figure 10) is used to access the configuration and management menus. The left and right soft keys

select values from parameter lists. Access to the Main Menu is achieved by pressing the right soft key. Access to the Operator
