The O
PERATOR
scroll box allows user to select greater than or less than for analog magnitude;
The V
ALUE
text field allows user to enter the magnitude value associated with greater than or less than
operator;
The H
OLD TIME
text field allows user to enter the time in milliseconds, where the threshold needs to be
exceeded to be considered valid;
The H
YSTERESIS
text field allows user to enter a percentage of the V
ALUE
, the quantity monitored needs to
exceed that percentage in order to end the event and to reset the threshold detector.
Once the threshold is created, it appears in the configuration interface menu. When selecting the threshold, a
screen shows the characteristics of the threshold selected, as shown in Figure 27 . It is possible to edit the
value, hold time, and hysteresis.
