Faceplate Interface
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 setpoints 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.
There are three groups of LED indicators. They are 469 Status, Motor Status, and
Output Relays.
