SEL-351A Relay Instruction Manual Date Code 20080213
Serial Port Communications and Commands
Command Explanations
To issue the OPE command, enter the following:
==>OPE <Enter>
Open Breaker (Y/N) ? Y <Enter>
Are you sure (Y/N) ? Y <Enter>
==>
Typing N <Enter> after either of the above prompts will abort the command.
The OPE command is supervised by the main board Breaker jumper (see
Table 2.5 and Table 2.6). If the Breaker jumper is not in place (Breaker jumper
= OFF), the relay does not execute the OPE command and responds:
Aborted: No Breaker Jumper
PUL Command (Pulse Output Contact)
The PUL command allows you to pulse any of the output contacts for a
specified length of time. The command format is:
PUL x y
To pulse OUT101 for 5 seconds:
==>PUL OUT101 5 <Enter>
Are you sure (Y/N) ? Y <Enter>
==>
If the response to the Are you sure (Y/N) ? prompt is N or n, the command
is aborted.
The PUL command is supervised by the main board Breaker jumper (see
Table 2.5 and Table 2.6). If the Breaker is not in place (Breaker jumper =
OFF), the relay does not execute the PUL command and responds:
Aborted: No Breaker Jumper
The relay generates an event report if any of the OUT101–OUT107 contacts are
pulsed. The PULSE command is primarily used for testing purposes.
Access Level 2
Commands
CON Command (Control Remote Bit)
The CON command is a two-step command that allows you to control Relay
Word bits RB1–RB16 (see Rows 27 and 28 in Table 9.5). At the Access
Level 2 prompt, type CON, a space, and the number of the remote bit you
wish to control (1–16). The relay responds by repeating your command
followed by a colon. At the colon, type the Control subcommand you wish to
perform (see Table 10.8).
where:
x = the output name (e.g., OUT101, OUT107, ALARM—see
Figure 7.26)
y = the pulse duration (1–30) in seconds. If y is not specified,
the pulse duration defaults to 1 second.
