Serial Port Communications and Commands
SEL ASCII Protocol Details
TIM (Time)
Access Levels 1, B, 2
The TIME 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 h:m:s; 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.
TRI (Trigger an Event)
Access Levels 1, B, 2
The TRIGGER command generates an event record. The command is a
convenient way to record all inputs and outputs from the relay at any time you
want (e.g., testing or commissioning). The event type is recorded as TRIG any
time the TRI command is issued.
Table 7.9 THE Command Choices
THE
Displays a thermal monitor report that indicates
the present thermal status of the transformer.
THE C
Clears the hourly profile, daily profile,
and thermal event data archives.
THE D
x y
Retrieves daily profile data from day x to day y.
If x and y are omitted, retrieves entire profile data.
If x or y is omitted, retrieves profile from day x (y) to present.
THE H
x y
Retrieves hourly profile data from day x to day y.
If x and y are omitted, retrieves entire profile data.
If x or y is omitted, retries profile from day x (y) to present.
THE
n
Displays saved thermal monitor report n
where n = 1 is the most recently saved report.
THE P
n
Loads preset value of accumulated insulation loss of life.
THE R
Clears the hourly profile, daily profile, and thermal
event data archives and resets the total loss-of-life values.
THE T
Displays the four temperature inputs received
from an SEL-2032, an SEL-2030, or an SEL-2020.
NOTE: After setting the time, allow
at least 60 seconds before powering
down the relay or the new setting may
be lost.
