The event logging can be set to "Status", the occurrence of a pre-defined event will be logged
with time and date. The pre-defined events are "Error in device", "Application error", "Out of
specification". for more information, refer to
Error messages on page 33.
"Limit"
If the event logger is set to "Limit" the event of a parameter exceeding a pre-set limit can be
logged.
"Measurement"
Choose the parameter for which the events should be logged.
"Threshold" and "Hysteresis"
The threshold is the limit setting. The hysteresis is the change required before the limit event
can be logged again.
Example: Threshold is set to 10 m
3 /h, hysteresis to 1 m 3 /h. An event will be logged if the flow
exceeds 10 m
3
/h. Another event can only be logged after the value
has gone under 10-1= 9 m 3 /h.
"Polarity"
If the polarity stands on "Normal" the polarity of the parameter is regarded. If the polarity stands
on "Absolute value" the direction of flow is not regarded and events will be logged at for example
both negative and positive values.
"Direction"
"Normal" or "Inverse" shows the direction of exceeding the threshold setting in order to log an
event. Normal is when the threshold value is passed by an increasing value of the parameter.
