3.4 Final Preparation of the Device
The used terminal screws must be tightened, including those that are not used. All the
plug connectors are correctly inserted.
Caution!
Don´t use force! 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 modified during the
tests. Check if protection, control and auxiliary functions to be found with the configu-
ration parameters are set correctly (Section 2.1.1, Functional Scope). All desired ele-
ments and functions must be set ON. Ensure that a copy of the setting values is stored
on the PC.
The user should check the device-internal clock and set/synchronize it if necessary,
provided that it is not synchronized automatically. Further details on this subject are
described in /1/.
The indication buffers are deleted under Main Menu → Annunciation → Set/Re-
set, 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. The
default display appears in the display, e.g. the display of operational measured value.
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.
