QUICK REFERENCE GUIDE
469 MOTOR MANAGEMENT RELAY – QUICK REFERENCE GUIDE 3
Programming can be accomplished via the front panel. To simplify programming and
provide a more intuitive interface, setpoints can also be entered with a PC running the no-
charge EnerVista 469 setup software provided with the relay. Actual values and setpoints
can be displayed, altered, stored, and printed. If settings are stored in a setpoint file, they
can be downloaded at any time to the front panel program port of the relay via a
computer cable connected to the serial port of any personal computer.
