The 469 Motor Management Relay was designed to display lagging angles. Therefore, if a
system condition would cause the current to lead the voltage by 45°, the 469 relay will
display such angle as 315° Lag instead of 45° Lead.
When the currents and voltages measured by the relay are zero, the angles displayed
by the relay and those shown by the EnerVista 469 Setup software are not fixed values.
