Min/Max Measurement Setup

2.23.5
Minimum and maximum values are calculated by the 7SJ80. Time and date of the last update of the values
can also be read out.
2.23.5.1

Functional Description

Minimum and Maximum Values
The minimum and maximum values for the three phase currents Ι
the three phase-to-phase voltages V
V , the real power P, reactive power Q, and apparent power S, the frequency; and the power factor cos ϕ are
0
calculated as primary values (including the date and time they were last updated).
The minimum and maximum values of the long-term averages listed in the previous section are also calcu-
lated.
The minimum and maximum values can be reset at any time via binary inputs or by using the integrated
control panel or the DIGSI software. Additionally, the reset can be carried out cyclically, starting at a preset
point of time.

Setting Notes

Minimum and Maximum Values
The tracking of minimum and maximum values can be reset automatically at a programmable point in time.
To select this feature, address 8311 MinMax cycRESET should be set to YES. The point in time when reset is
to take place (the minute of the day in which reset will take place) is set at address 8312 MiMa RESET TIME.
