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!
The settings should be checked again, if they were changed during the tests. Check if all protection, control
and auxiliary functions to be found with the configuration parameters are set correctly (Section 2.1.1 Func-
tional Scope, Functional Scope) and all desired functions are set to ON. Keep a copy of all setting values on a
PC.
The device-internal clock should be checked and set, if necessary.
The annunciation buffers are deleted under MAIN MENU → Annunciations → Set/Reset, so that future infor-
mation will only apply to actual events and states (see also SIPROTEC 4 System Description). 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).
Reset the counter of the operational measured values (e.g. operation counter, if available) under MAIN MENU
→ Measured Values → Reset (also see 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 box (e.g. the display of operational measured values).
Clear the LEDs on the front panel of the device by pressing the LED key, so that they show only real events and
states in the future. 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 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.
