Siemens 7SJ82, Manual

Page: 1025 / 1638

Parameter:
Down integration time
•
Default setting
(_:13861:102) Down integration time
=
3.00 min
Use the parameter
Down integration time
in order to determine the duration until the internal integra-
tion value is linearly reduced from 100 % to 0 %.
For example, if the integration value is 52 %, a duration of 52 % × down integration time is required until the
integration value 0 % is reached. When using this parameter, the preloading of a capacitor can be considered
and therefore released quicker.
If you are knowledgeable about recovery time of stressed capacitors, they can be considered with this param-
eter.
Parameter:
Dropout delay
•
Default setting
(_:13861:7) Dropout delay
=
1.00 s
The parameter
Dropout delay
can be used to prevent resetting of the integral value in the event that the
measured value briefly falls below the dropout threshold.
