7.2.4.
Conditions
This section is used for parameterization of trigger and alert conditions for sensors, analog, and
digital inputs.
7.2.4.1.
Sensors
and analog inputs
For every sensor two types of fields are presented
–
one for the trigger conditions (“Min”,
“Max”
,
and “Hys.”) and another one for the wanted action.
“Min” and “Max” indicate the border of the working range for the monitored parameter.
The
“Max” trigger condition occurs when the value exceeds the trigger set point.
The
“Min” trigger
condition occurs when the value is lower than the trigger set point. In both cases, the
monitored parameter goes out of range.
Coming back in range for the observed parameter is considered when the value goes higher
than (Min + Hys) or lower than (Max
–
Hys). Hysteresis (“Hys”) is used to prevent excessively
triggering when the value fluctuates around the trigger point.
