Control During Operation

7-177SA6 Manual

C53000-G1176-C133-1

If the device is provided with analog outputs allocated to certain measured values

during the configuration according to Section 5.1, they can be read out in the display

(e.g. analog instrument).

Except for the current measured values the user can also read out the minimum,

maximum and long-term measured values. The interval range for the calculation of the

average value was set in Subsection 6.21.4.

The following average values are available:

• I

dmd, I

dmd: the measured values of the phase currents and

symmetrical positive sequence system;

• Pdmd, Pdmd Forw, Pdmd Rev: the active power as a whole and separately

according to Demand Forward and Demand Reverse;

• Qdmd, QdmdForw, QdmdRev: the reactive power as a whole and separately

according to Demand Forward and Demand Reverse;

• Sdmd: the apparent power.

For the following values both the minimum and the maximum values are available:

• I

, I

: phase currents and the symmetrical positive sequence system of the

currents;

• I

d, I

d: average values of the phase currents and the symmetrical

positive sequence of the currents;

• U

L1–E

, U

: phase-earth voltages and symmetrical positive sequence

system of the voltages;

• U

L1–L2

, U

L2–L3

, U

L3–L1

, 3U

: phase-phase voltages and the triple zero voltage;

• PForw, PRev, QForw, QRev, S: active and reactive power separately according to

Demand Forward and Demand Reverse as well as apparent power;

• Pd, Qd, Sd: average values of active, reactive and apparent power;

• cos ϕ Pos, cos ϕ Neg: power factor separately according Demand Forward and

Demand Reverse;

• f: frequency.

From the

Device Front

With a device ready for operation, first press the key. The 0$,10(18 appears.

Use the key to select the menu item0HDVXUHPHQW, and switch to the list of

measured values using the key. The 0($685(0(17 selection appears. See figure

7-19.
