Status Reporting Features

General status reporting is available through the ASCII command interface using the RG-STAT (report
general, status) command. This report assembles all of the information required to determine the relay
status. For more information on general status reporting, see Section 6, Reporting and Alarm Functions,
General Status Reporting, General Status Report.

Fault reporting and target data is dependent on the proper setting of trip, pickup, and logic trigger
expressions (via the SG-TRIGGER command) and the assignment of protective elements to be logged as
targets (via the SG-TARG command).

While the design of the relay facilitates obtaining and verifying targets and event data, it is not always
necessary to utilize the relay functions to determine if the device operated while testing. You may simply
use an ohmmeter or continuity tester to monitor the output contact status.

The following is a summary of ASCII commands where target and event data may be viewed:

• RF provides a directory of fault summary reports in memory
• RF-# provides a summary report giving targets, timing and event data
• RG-TARG provides target data only
• RS provides a summary of sequence of events records
• RS-F# provides a detailed SER report for the selected fault event number
• RS-# provides a detailed SER report on the last numbered events

For more information on human-machine interface (HMI) menu trees, see Section 10, Human-Machine
Interface
. In addition, much of this information can be accessed through BESTCOMS

™. See Section 14,

BESTCOMS Software, for details.

Event Reporting Features

The SER function of the relay records protective element output changes, overcurrent element pickup or
dropout, input/output contact state changes, logic triggers, setting group changes, and setting changes.
For more information on event reporting, see Section 6, Reporting and Alarm Functions, Sequence of
Events Recorder
.

The following summarizes the reporting capabilities of the relay through the front panel HMI:
• Trip LED (Flashing): flashes during pickup of protective elements based on the pickup logic

expression set in the SG-TRIGGER command.

• Trip LED (sealed-in): stays lit after trip logic becomes TRUE based on the trip logic expression set in

the SG-TRIGGER command.

• TARGETS, Screen 1.2: Provides target data.
• ALARMS, Screen 1.3: Provides alarm data (including BKR FAIL, REC FAIL and REC LO).
• FAULT REPORTS, Screen 4.1: Indicates new fault reports
• EVENT REPORT, Screen 4.2: Gives the number of new events logged by the SER since the last new

counter reset (executed only by the RS=0 command). Events must be viewed using the RS and RS#
commands listed in the previous paragraph.

ACCEPTANCE TESTING

Although Basler Electric performs detailed acceptance testing on all new relays, it is generally
recommended that you perform each of the following acceptance test steps before installation.
Performing these steps tests each function of the BE1-700 relay to validate that the relay was
manufactured properly and that no degradation of performance occurred because of shipping. ASCII
communication is discussed throughout this section but BESTCOMS can also be used for the majority of
settings and tests. See Section 14, BESTCOMS Software, for details.

Test Equipment

Suitable test equipment requires a minimum of two current source elements, two voltage source
elements, and a contact wetting voltage. Test equipment should also have the capability of varying the
frequency and the angle of the voltage and current sources.

Refer to Figure 12-3 for a BE1-700C and Figure 12-4 for a BE1-700V.
