SEL-387E Instruction Manual
The front-panel LEDs remain remapped until the front panel times out, the TAR R command is
executed, or the <TARGET RESET> button is pushed.
Refer to Section 4: Control Logic for a list of the Relay Word bits and their corresponding rows.
TAR R (Reset Targets)
Access Levels 1, B, 2
The TAR R command resets the default row for the TAR and TAR F commands to 0, and
remaps the second row of front-panel LEDs to display Row 1, which is the standard target
display. It also resets any tripping front-panel targets.
Use the TAR R command to return the front-panel LEDs to the standard targets when you are
done using the TAR or TAR F command for testing.
TEST DB
Access Levels B, 2
Use the TEST DB name 01 [name02…name10][s] command to pulse up to 10 binaries (Relay
Word bits), where name01…name10 are the Device Word bits that are to be pulsed and s is the
number of seconds to pulse the binaries. The range for s is 1 to 30 seconds with a default of one
second. If the binary is a logical 0, the command will pulse it to one. If the binary is a logical 1,
the command will pulse it to zero. This command affects both SER and IEC 61850
communications.
TFE (Through-Fault Event Report)
The TFE command displays the following data for each individually recorded through-fault
event:
• Date and time of the through fault
• Duration (seconds) of the through fault
• Maximum current (Amps primary) for each monitored current input
The following cumulative values (updated for each new through-fault event) are also displayed:
• Through-fault count
• Simple I
2
t calculation for each monitored current input
There are various choices for the TFE command, listed briefly below. Refer to Section 5:
Metering and Monitoring for a complete description of the through-fault event reports:
TFE Displays cumulative and individual through-fault event data. The twenty (20) most
recent individual events are displayed.
TFE A Displays cumulative and individual through-fault event data. All the most recent
individual events are displayed, up to 1200.
TFE C Clears/resets cumulative and individual through-fault event data.
