3.4 Final Preparation of the Device
The used terminal screws must be tightened, including those that are not used. All the
plug connectors must be correctly inserted.
Caution!
Do not use force!
The permissible tightening torque must not be exceeded as the threads and terminal
chambers may otherwise 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 to be
found with the configuration parameters are set correctly (Section 2.1.3, Functional
Scope) and that all desired elements and functions have been set
ON
. Keep a copy of
all of the in-service settings on a PC.
The user should check the device-internal clock and set/synchronize it if necessary,
provided that it is not synchronised automatically. For further information refer to
SIPROTEC 4 System Description /1/.
The indication buffers are deleted under Main Menu

, so that in the future they only contain information on actual events and
states. The numbers in the switching statistics should be reset to the values that were
existing prior to the testing.
The counters of the operational measured values (e.g. operation counter, if available)
are reset under
Main Menu

.
Press the
ESC
key, several times if necessary, to return to the default display. The
basic window 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 so doing, possibly stored output relays will also be reset. Press-
ing the
LED
key also serves as a test for the LEDs on the front panel because they
should all light up when the button is pressed. 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.
If a test switch is available, it must be in the operating position.
The device is now ready for operation.
