Front Panel 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 750/760 Setup
software.
The 40-character liquid crystal display (LCD) allows visibility under varied lighting
conditions. When the keypad and display are not being used, system information is
displayed by scrolling through a maximum of 30 user-defined default messages. These
default messages appear only after a user-defined period of inactivity. Pressing any key
during default message scrolling returns 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.
