SEL-387E Instruction Manual
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.
TIM (Time)
Access Levels 1, B, 2
The TIM command displays or sets the time stored by the internal clock. The time is set or
displayed on a 24-hour clock basis, not a.m./p.m. View the current time with TIM<ENTER>.
To set the clock, type TIM t1<ENTER> where t1 is the new time in hours:minutes:seconds; the
seconds are optional. Separate the hours, minutes, and seconds with colons, semicolons, spaces,
commas, or slashes. The following example sets the clock to 23:30:00:
=>>TIM 23:30:00<ENTER>
23:30:00
=>>
A quartz crystal oscillator provides the time base for the internal clock. You can also set the
time clock automatically through the relay time-code input using a source of demodulated
IRIG-B time code.
Note: After setting the time, allow at least 60 seconds before powering down the relay or the
new setting may be lost.
TRI (Trigger an Event)
Access Levels 1, B, 2
The TRI command generates an event record. The command is a convenient way to record all
inputs and outputs from the relay any time you want (e.g., testing or commissioning). The event
type is recorded as TRIG any time the
TRI command is issued.
