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.
