Final Preparation of the Device
Firmly tighten all screws. Tighten all terminal screws, including those that are not used.
CAUTION
Inadmissable tightening torques
Non–observance of the following measure can result in minor personal injury or property damage.
²
The tightening torques must not be exceeded as the threads and terminal chambers may otherwise be
damaged!
In case service settings were changed, check if they are correct. Check if power system data, control and
auxiliary functions to be found with the configuration parameters are set correctly (Section 2 Functions). All
desired elements and functions must be set ON. Keep a copy of all of the in-service settings on a PC.
Check the internal clock of the device. If necessary, set the clock or synchronize the clock if the element is not
automatically synchronized. For assistance, refer to the /1/ SIPROTEC 4 System Manual.
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 (see also /1/ SIPROTEC 4 System Manual). The coun-
ters in the switching statistics should be reset to the values that were existing prior to the testing (see
also /1/ SIPROTEC 4 System Manual).
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 operation 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, also output relays probably memorized are reset. 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. Any LEDs that are lit after the
clearing attempt are displaying actual conditions.
The green “RUN” LED must be on. The red “ERROR” LED must not be lit.
Close the protective switches. If test switches are available, then these must be in the operating position.
The device is now ready for operation.
