7.3.5 Control of the Isolator Replica
For test purposes, the isolator positions of all available feeders can be preset indepen-
dent of the state of the binary inputs. For this purpose, the system is to be set to test
mode via DIGSI. At the beginning of the test mode, the actual binary input positions of
the isolator apply. The setting of the isolator position during the test mode is made in
the dialog box "Generate indications" as desired.
Please pay attention that in DIGSI Device Configuration the operating mode Online is
prerequisite for the use of these test functions. Using parameter
OutEn BU-TEST (5112A/CU) you can enable the command output during the test
operation via relay. For safety reasons the pre-setting "No", i.e. the relay output, is
locked. This ensures that no accidental triggering may occur during the test mode. The
parameter OutEn BU-TEST (5112A/CU) is only effective during the test mode.
The following isolator status indications can be generated and transmitted to the pro-
tection device:
• OPEN position
• CLOSED position
• Not current (0-0)
• Intermediate position (1-1)

This also opens the "Simulation Mode" (Figure 7-10, page 282) in a dedicated window.
You can place this window on top using the icon in the taskbar.
When you "Close" the above window (Figure 7-9, page 281) the window "Simulation
Mode" will be closed, too.
