All messages are displayed on a 40-character LCD display to make them visible under poor
lighting conditions and from various viewing angles. Messages are displayed in plain
English and do not require the aid of an instruction manual for deciphering. While the
keypad and display are not actively being used, the display will default to user defined
status messages. Any trip, alarm, or start inhibit will automatically override the default
messages and appear on the display

location and downloaded through this port using the EnerVista 369 Setup software. Local

downloaded to the 369 Relay flash memory through this port. Upgrading of the relay
firmware does not require a hardware EPROM change.
