4 USER INTERFACES 4.1FRONT PANEL INTERFACE
The front panel provides local operator interface with a liquid crystal display, LED status indicators, control keys, and pro-
gram port. The display and status indicators update alarm and status information automatically. The control keys are used
to select the appropriate message for entering setpoints or displaying measured values. The RS232 program port is also
provided for connection with a computer running the 750/760PC software.
The 40-character liquid crystal display is backlit to allow visibility under varied lighting conditions. While the keypad and dis-
play are not being used, the screen will display system information by scrolling through a maximum of 30 user-selected
default messages. These default messages will only appear after a user programmed period of inactivity. Pressing any key
during default message scrolling will return the display to the last message shown before the default messages appeared.
Trip and alarm condition messages will automatically override default messages.
