Siemens SENTRON PAC4220 - 2.3.4 Other Properties of Measured Variable Representation

The values are updated at time-synchronized, parameterizable intervals:
• A default per
iod length of 10seconds is set for the measured values of average 1 (󹪝le 1).
• A default period length of 15minutes is set for the measured values of average 2 (󹪝le 2).
• Harmonic average (󹪝le 3)
The averaging time can be set between 3 seconds and 1 year.
2.3.4 Other properties of measured variable representation
Zero point suppression level
The zero point suppression level can be set in 0.1% steps in the range from 0% to 10% of the
primary rated current of the external current transformer (default value 0.0%). Currents within
this range are indicated on the display with "0" (zero).
Lowest limit of operating hours counter
1)
The operating hours counter starts as soon as load is measured at the current input. The lowest
limit can be set in 0.1% steps in the range from 0% to 10% of the primary rated current of the
external current transformer (default value 0.0%).
As long as the current value remains below the de󹪝ned lowest limit, the operating hours
counter is not incremented.
1)
This function will be available at a later time via a 󹪝rmware update.
