Final Preparation of the Device

SIPROTEC 4, 7SJ62/63/64 Handbuch
C53000-G1140-C147-A, Edition 07.2015
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 prop-
erty damage.
The tightening torques 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 if protection, control and auxiliary functions to be found with the configuration
parameters are set correctly (Section 2.1.1, Functional Scope). 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
SIPROTEC 4 System Description.
The annunciation buffers are deleted under MAIN MENU → Annunciations →
Set/Reset, so that future information will only apply for 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 counters of the operational measured values (e.g. operation counter, if
available) under MAIN MENU → Measured Value → Reset (see also SIPROTEC 4
System Description).
Press the E
SC
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 prob-
ably 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.
