ISTURBANCE RECORDER
The disturbance recorder function can record analog signals and binary status signals.
These signals are user configurable. The disturbance recorder function has a binary input
signal, which serves the purpose of starting the function. The conditions of starting are
defined by the user. The disturbance recorder function keeps on recording during the active
state of this signal but the total recording time is limited by the timer parameter setting. The
pre-fault time, max-fault time and post-fault time can be defined by parameters.
