Additionally, if GPS synchronization is used, check that the GPS signal is received: ap-
proximately 3 seconds after startup of the processor system, the message „>GPS
failure“ „OFF“ appears.
3.3.3 Checking the System Interface
Prefacing Remarks If the device features a system interface and uses it to communicate with the control
centre, the DIGSI
®
device operation can be used to test if annunciations are transmit-
ted correctly. This test option should however definitely not be used while the device
is in service on a „live“ system.
DANGER!
Sending or receiving annunciations via the system interface by means of the
test function is a real information exchange between the SIPROTEC device and
the control centre. Connected operating equipment such as circuit breakers or
disconnectors can be operated in this way!
Non-observance of the following measure will result in death, severe personal injury
or substantial property damage.
Equipment used to allow switching such as circuit breakers or disconnectors is to be
checked only during commissioning. Do not under any circumstances check them by
means of the testing mode during „real“ operation performing transmission and recep-
tion of messages via the system interface.
Note
After termination of this test, the device will reboot. Thereby, all indication buffers are
erased. If required, these buffers should be extracted with DIGSI
®
prior to the test.
The system interface test is carried out Online using DIGSI

• Double-click in the list view on Generate indications. The dialog box Generate
indications is opened (see Figure 3-19).
Structure of the
Dialog Box
In the column Indication, all message texts that were configured for the system inter-
face in the matrix will then appear. In the column Setpoint you determine a value for
the indications that shall be tested. Depending on the type of message different enter-
ing fields are available (e.g. message ON / message OFF). By clicking on one of the
buttons you can select the desired value from the pull-down menu.
