Changing the Operating State
When clicking one of the buttons in the column Action for the first time, you will be prompted for the pass-
word no. 6 (for hardware test menus). After correct entry of the password, individual annunciations can be
initiated. To do so, click on the button Send on the corresponding line. The corresponding message is issued
and can be read out either from the event log of the SIPROTEC 4 device or from the substation control system.
As long as the window is open, further tests can be performed.
Test in Message Direction
For all information that is transmitted to the central station, test the options in the list which appears in
SETPOINT Status:
•
Make sure that each checking process is carried out carefully without causing any danger (see above and
refer to DANGER!)
•
Click on Send in the function to be tested and check whether the transmitted information reaches the
central station and shows the desired reaction. Data which are normally linked via binary inputs (first
character ">") are likewise indicated to the central power system with this procedure. The function of the
binary inputs itself is tested separately.
Exiting the Test Mode
To end the System Interface Test, click on Close. The device is briefly out of service while the start-up routine
is executed. The dialog box closes.
Test in Command Direction
The information transmitted in command direction must be indicated by the central station. Check whether
the reaction is correct.
