Status and Event Reporting Features
General status reporting is available through the ASCII command interface using the RG-STAT (report
general, status) command or the optional front panel human-machine interface (HMI) with LCD display.
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. Several different HMI screens display the same information. Section 6, Reporting
and Alarm Functions, General Status Reporting, General Status Report details the location and number of
each of the HMI screens for every line in the 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).
The SER function of the relay records protective element output state 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 Function.
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
The following summarizes the reporting capabilities of the relay through the optional front panel HMI.
•
Flashing Trip LED: flashes during pickup of protective elements based on the pickup logic
expression set in the SG-TRIGGER command.
•
Trip LED (sealed-in): stays illuminated after trip logic goes TRUE based on the trip logic
expression set in the SG-TRIGGER command
•
\STAT\TARGETS\DETAILS (Screen 1.1.1): provides target data
•
\STAT\ALARMS (Screen 1.2.1): provides alarm data (including BKR FAIL, REC FAIL and REC
LO)
•
\REPRT\FAULT\M_REC\DETAILS (Screen 4.1.1.1): provides targets and fault summary data
•
\REPRT\SEQ (Screen 4.2): provides the number of new events logged by the SER since the last
new counter reset (resettable only through ASCII command RS=0), events must be viewed using
RS and RS-# commands listed in the previous paragraph.
For more information on HMI menu trees, see Section 10, Human Machine Interface.
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 ohm-meter or continuity tester to monitor the output contact status.
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 when you receive the relay.
Performing these steps tests each function of the BE1-CDS relay to confirm that no degradation of
performance occurred as a result of shipping.
Test Setup
When performing the test setups (connections) for each of the following steps, refer to Figure 13-1 for
terminal locations.
Test Equipment
Suitable test equipment requires a minimum of two current source elements, two voltage source elements
(for relay power and contact wetting voltage), and circuit monitoring with timing algorithms.
