Min/Max Measurement Setup
Minimum and maximum values are calculated by the 7SK80. Time and date of the last update of the values
can also be read out.
2.18.5.1 Description
Minimum and Maximum Values
The minimum and maximum values for the three phase currents I
three phase-to-phase voltages V
the thermal measured value of overload protection Θ/Θ
power S, the frequency; and the power factor cos ϕ are 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 calculated.
The min/max values can be reset via binary inputs, via DIGSI or via the integrated control panel at any time. In
addition, the reset can also take place cyclically, beginning with a pre-selected point in time.
2.18.5.2 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.
The reset cycle in days is entered at address 8313 MiMa RESETCYCLE, and the beginning date of the cyclical
process, from the time of the setting procedure (in days), is entered at address 8314 MinMaxRES.START.
