3.4 Final Preparation of the Device

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 apply force!
The tightening torques must not be exceeded as the threads and terminal chambers may otherwise be dam-
aged!
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 functions must be switched ON. Ensure that a copy of the setting values is stored
on the PC.
Check the internal clock of the device. If necessary, set the clock or synchronize the clock if the element is not
automatically synchronized. Further details on this subject are described in /1/.
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. 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 → Measurement → Reset.
Press the ESC key, several times if necessary, to return to the default display.
Clear the LEDs on the front panel by pressing the LED key, so that they only show real events and states. In
this context, saved output relays are reset, too. 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 pressed. If the LEDs display states relevant by that
moment, these LEDs, of course, stay lit.
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.
