Threshold
(communication object
Change Threshold value 1
)
The threshold value evaluation is carried
out after bus voltage recovery using the
parameterized threshold, whereby the last
status threshold detected in operation is
used for comparison. Should no Status
Threshold exist before bus voltage failure,
the factory set status (hysteresis limit
undershoot) is assumed.
The currently saved thresholds in the
SA/S are overwritten with the values
parameterised in the ETS, if the overwrite
parameter at download is set to yes.
When parameterised to no, the values
stored via KNX are retained.
Overwrite Threshold 1 can be
parameterised (parameter window
X: General
).
The Threshold 1 stored
in the SA/S will be
restored.
