Final Preparation of the Device
The used terminal screws must be tightened, including all screws that are not used. All plug connectors must
be inserted correctly.
CAUTION
Do not use force!
The permissible tightening torques must not be exceeded as otherwise the threads and terminal
chambers may be damaged!

The setting values should be checked again if they were changed during the tests. Check in particular
whether all protection, control and auxiliary functions in the configuration parameters are set correctly
(Section 2.1.1 Functional Scope) and that all desired functions have been set to ON. Make sure that a backup
copy of all setting values is stored on the PC.
Check the internal clock of the device. If necessary, set the clock or synchronize the clock if it is not synchron-
ized automatically. Further details on this subject are described in /1/ SIPROTEC 4 System Description.
The indication buffers are deleted under Main Menu → Annunciations → Set/Reset so that they only contain
information on actual events and states in the future. The counters of the switching statistics should be reset
to the values prior to the testing.
The counters of the operational measured values (e.g. operation counter, if available) are reset under Main
Menu → Measurement → Reset.
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).
When you press the LED key, the displays in the Web Monitor are deleted so that these will only show informa-
tion about real events and states in the future. In this context, any memorized output relays are reset. Pressing
the LED key also serves as a test for the LEDs on the front panel, because the routable LEDs should all light up
when the button is pressed. Any LEDs that are lit after the clearing attempt display actual conditions.
The green “RUN” LED must light up, whereas the red “ERROR” LED 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.
