3.3.1 Sliding window demand values
The sliding window demand value is the arithmetic mean of all measured values that occur
within a configurable averaging time. "Sliding" means that the interval for the demand
calculation is continuously shifted as a function of time.

Figure 3-1 Sliding window demand
The sliding window demand values are updated 60 times per set averaging time. A lower
limit of 200 ms applies here. If an averaging time of 3, 5 or 10 seconds is set, the demand
value is formed with fewer values.
Available sliding window demand values
SENTRON PAC4200 supplies sliding window demand values for a large number of
measured variables:
● Per phase or as a total value over all phases
● With the maximum and minimum values as well as the time stamp for the maximum and
minimum values
The "Measured variables – overview" table above lists the available sliding window demand
values.
The sliding window demand values are represented on the display and can be called via the
communication interfaces.
