The front panel provides local operator interface with a liquid crystal display, LED status
indicators, control keys, and program port. The display and status indicators update alarm
and status information automatically. The control keys are used to select the appropriate
message for entering settings or displaying measured values. The RS232 program port is
also provided for connection with a computer running the EnerVista 469 Setup software.
The 40-character liquid crystal display allows visibility under varied lighting conditions.
While the keypad and display are not being used, the screen will display system
information by scrolling through a maximum of 20 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. Any trip, alarm, or start block is displayed
immediately, automatically overriding the default messages.
