4.1 Trig signals The trig conditions affect the entire disturbance report. As soon as a trig
condition is fulfilled, a complete disturbance report is recorded. On the
other hand, if no trig condition is fulfilled, there is no disturbance report,
no calculation of distance to fault, no indications, and so on. This implies
the importance of choosing the right signals as trig conditions.
A trig can be of type:
• Manual trig
• Binary-signal trig
• Analogue-signal trig (over/under function)
4.1.1 Manual trig Manual trig starts from the built-in MMI or from a front-connected PC (or
SMS). This is found on the MMI menu tree at:
DisturbReport
Manual Trig
4.1.2 Binary trig A trig on a binary signal can be activated on either a logical 1 or a
logical 0. When a binary input is used as trig, the signal must stay for at
least 15 ms to be picked up.
Note that when a binary signal is programmed to trig on a logical 0, this
signal is not presented as an indication in the disturbance report.
4.1.3 Analogue trig All analogue signals are available for trigger purposes, no matter if they
are recorded in the disturbance recorder or not. But the Disturbance
Recorder function must be installed in the terminal.
