Description

Display operational and status events in chronological order beginning with the latest event. Operational messages include pickup and drop-out of enabled protections and alarms, pickup and drop-out of binary inputs, signal outputs, trips, relay diagnostics, and other relay operational information.

Display the target history log for the most recent system fault, from fault detection until drop-out. The fault number, beginning fault time and time resolution display first, followed by the applicable annunciations. Fault annunciations are available for distance protection, emergency overcurrent protection, fault location, high- resistance ground fault protection, and the internal auto-reclose function.

Display the target history log for the second to last fault. See address 5200 for available fault messages.

Display the target history log for the third to last fault. See address 5200 for available fault messages.

Display the annunciations generated for the last three ground faults for ungrounded systems (isolated or compensated).

Display the circuit breaker operation statistics.

Display the operational measured values, which are calculated based on the values entered for the protected system settings and on the relay rated frequency. The data displays in absolute primary values and in percent of the rated relay values.

For ungrounded systems, this address displays the measured values that occurred during the last ground fault.

Configure the binary inputs.

Configure the signal relays.

Configure the LEDs, including whether the indication is latched or unlatched.

Configure the trip relays.

Indicate whether the relay is part of a substation control system via the rear communications port.

Program the language selection, date format, substation identification numbers for the relay; select which operational messages to display, which fault event annunciations to display, etc.

Indicate which protection and operating functions are available in the relay, e.g., emergency overcurrent protection, fault location detection, internal auto-reclose, etc. Also identify the rated frequency for the protected system.

Program how the auto-reclose function interacts with the protection functions of the relay.

Set the date and time for the real-time clock. You can also specify a difference time, which is primarily used to synchronize the relay’s real-time clock with another reference.
