SEL-387E Instruction Manual
TFE n Displays cumulative and individual through-fault event data. The n most recent
individual events are displayed, where n = 1 to 1200.
TFE P Preloads cumulative through-fault event data.
TFE R Clears/resets cumulative and individual through-fault event data.
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.
