The setting values should be checked again, if they were modified during the tests. Check if protection,
control and auxiliary functions to be found with the configuration parameters are set correctly (Section

copy of the setting values is stored on the PC.
The user should check the device-internal clock and set/synchronize it if necessary, provided that it is not
synchronized automatically. Refer to the SIPROTEC 4 System Description for more information on this.
The indication buffers are deleted under Main Menu → Annunciation → Set/Reset, so that in the future
they only contain information on actual events and states. The counters in the switching statistics should be
reset to the values that were existing prior to the testing (see also SIPROTEC 4 System Description).
The counters of the operational measured values (e.g. operation counter, if available) are reset under Main
Menu → Measurement → Reset (see also SIPROTEC 4 System Description).
Press the ESC key, several times if necessary, to return to the default display. The default display appears in
the display (e.g. display of operational measured values).
Clear the LEDs on the front panel by pressing the LED key, so that they only show real events and states. In
this context, saved output relays are reset, too. Pressing the LED key also serves as a test for the LEDs on the
front panel because they should all light when the button is pushed. If the LEDs display states relevant by that
moment, these LEDs, of course, stay lit.
The green "RUN" LED must light up, whereas the red "ERROR" must not light up.
Close the protective switches. If test switches are available, then these must be in the operating position.
The device is now ready for operation.
