Proceed as follows in order to check the binary inputs:
• Activate in the system each of the functions which cause the binary inputs.
• Check the reaction in the Status column of the dialog box. To do this, the dialog box
must be updated. The options may be found below under the margin heading „Up-
dating the Display“.
• Finish the test sequence (see margin heading below „Exiting the Procedure“).
If, however, the effect of a binary input must be checked without carrying out any
switching in the system, it is possible to trigger individual binary inputs with the hard-
ware test function. As soon as the first state change of any binary input is triggered
and the password No. 6 has been entered, all binary inputs are separated from the
system and can only be activated via the hardware test function.
Test of the LEDs The LEDs may be tested in a similar manner to the other input/output components. As
soon as the first state change of any LED has been triggered, all LEDs are separated
from the internal device functionality and can only be controlled via the hardware test
function. This means e.g. that no LED is illuminated anymore by a protection function
or by pressing the LED reset button.
Updating the
Display When the dialog box Hardware Test is opened, the present conditions of the hard-
ware components at that moment are read in and displayed.
An update is made:
• For the particular hardware component, if a command for change to another state
was successful,
• For all hardware components if the Update button is clicked,
• For all hardware components with cyclical updating (cycle time is 20 sec) if the Au-
tomatic Update (20 sec) field is marked.
Exiting the Proce-
dure To end the hardware test, click on Close . The dialog box closes. Thus, all the hard-
ware components are set back to the operating state specified by the plant states. The
processor system is restarted, then the device is ready for operation.
3.3.5 Checking the Setting Consistency
The 7UT613/63x device checks the settings of the protection functions against the
corresponding configuration parameters. Any inconsistencies will be reported. For in-
stance, earth fault differential protection cannot be applied if there is no measuring
input for the starpoint current between starpoint of the protected object and the earth-
ing electrode.
The device also checks the matching factors between the rated currents of the CT’s
and the operational currents of the protected object(s) as processed by the protection
functions. If very high deviations combined with sensitive protection settings are dis-
covered an alarm is output which also indicates the suspicious setting address(es).
Check in the operational or spontaneous annunciations that there is not any informa-
tion on inconsistencies.
