SOURCE Monitored data source.
Almost all measured variables can be selected

Default value:
V a
MODE Relational operators
GREATER THAN, LOWER THAN the value in
the "VALUE" field.
Default operator: GREATER THAN
VALUE Monitored threshold.
PICKUP DELAY Delay before reporting the limit violation in seconds.
The delay refers to the appearance of the limit
violation or the point of exceeding the threshold
defined in the "VALUE" field. See the figure below
"Effect of delay".
Range: 0 to 10 s
Default value: 0 s
HYSTERESIS Threshold buffer, prolongs the limit violation.
The hysteresis refers to the disappearance of the limit
violation or the point when the level returns below the
defined threshold.
Range: 0.0 to 20.0 %
Default value: 0,0 %
The percentage refers to the threshold value in the
"VALUE" field. See the figure below "Effect of delay
and hysteresis".
STATUS Indicates whether the limit value is currently violated.
Yes, violation.
No, no violation.
