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.
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 #
• RS-# provides a detailed SER report on the last # events
For more information on HMI menu trees, see Section 10, Human-Machine Interface.
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 HM:
• 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 BE1-951 relay to validate that the relay was
manufactured properly and that no degradation of performance occurred as a result of shipping.
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.
NOTE
Test connections referred to in this section are for an H1 style case relay. Refer
to Figure 13-1 (H1 case) for terminal locations. If testing a relay in an S1 case,
modify the current and potential test connections according to the terminal
locations shown in Figure 13-2 (S1 case) or Figure 13-3 (S1 double-end case).
