The additional functions of the 7UT613/63x differential protection relay include:
• processing of messages,
• processing of operational measured values,
• storage of fault record data.
For a detailed fault analysis, information regarding the reaction of the protection
device and the measured values following a system fault are of interest. For this pur-
pose, the device provides information processing which operates in a threefold
manner:
Important events and states are displayed by LEDs on the front cover. The relay also
contains output relays for remote signaling. Most indications and displays can be con-
figured differently from the delivery default settings (for information on the delivery
default setting see Appendix). The SIPROTEC 4 System Description gives a detailed
description of the configuration procedure.
The output relays and the LEDs may be operated in a latched or unlatched mode
(each may be individually set).
The latched conditions are protected against loss of the auxiliary voltage. They are
reset
• On site by pressing the LED key on the relay,
• Remotely using a binary input configured for that purpose,
• Using one of the serial interfaces,
• Automatically at the beginning of a new pickup.
Status messages should not be latched. Also, they cannot be reset until the condition
to be reported has been cancelled. This applies to, e.g. indications from monitoring
functions, or the like.
A green LED displays operational readiness of the relay („RUN"), and cannot be reset.
It goes out if the self-check feature of the microprocessor recognizes an abnormal oc-
currence, or if the auxiliary voltage fails.
When auxiliary voltage is present but the relay has an internal malfunction, the red
LED („ERROR") lights up and the processor blocks the relay.
DIGSI enables you to control selectively each output relay and LED of the device and,
in doing so, check the correct connection to the system. In a dialog box you can, for
instance, cause each output relay to pick up, and thus test the wiring between the
7UT613/63x and the station, without having to create the indications masked to it.
Events and conditions can be read out on the display on the front panel of the relay.
Using the front operator interface or the rear service interface, for instance, a personal
computer can be connected, to which the information can be sent.
