7.2 Removing an equivalent circuit
An active equivalent circuit can be identified in the “Replace” display, as in the following example:
Figure 29: View of an equivalent circuit
After rectifying a fault or e.g. replacing a module, the equivalent circuit can be reversed. This is
done by activating the radio button “undo replacement” in the column “Replace options” and then
pressing the “Submit” button. This procedure is necessary, regardless of whether the equivalent
circuit was set up manually or automatically. The U 100-C controller undoes the equivalent circuit
if the operating module can be restarted without a fault. This process is also documented in the
Replacement log file.
