If the 469 is applied on a synchronous motor, it is desirable not to trip or alarm on power factor until the field has been
applied. Therefore, this feature can be blocked until the motor comes up to speed and the field is applied. From that point
forward, the power factor trip and alarm elements will be active. Once the power factor is less than either the Lead or Lag
level, for the specified delay, a trip or alarm will occur indicating a Lead or Lag condition. The power factor alarm can be
used to detect loss of excitation and out of step.
