Date Code 20001006 Serial Port Communications and Commands 10-35
SEL-351 Instruction Manual
To issue the OPE command, enter the following:
=>>OPE <ENTER>OPE <ENTER>
Open Breaker (Y/N) ? Y <ENTER>Y <ENTER>
Are you sure (Y/N) ? Y <ENTER>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 2.6 and Table 2.7).
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
where: x is the output name (e.g. OUT1, OUT107, ALARM, OUT211 - see
Figure 7.28 through Figure 7.30).
y is the pulse duration (1-30) in seconds. If y is not specified, the pulse
duration defaults to 1 second.
To pulse OUT1 for 5 seconds:
=>>PUL OUT1 5 <ENTER>PUL OUT1 5 <ENTER>
Are you sure (Y/N) ? Y <ENTER>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 2.6 and Table 2.7).
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 OUT1 through OUT11 (Model 0351xT) or
OUT101 through OUT107 (Models 0351x0, 0351x1, or 0351xY) contacts are pulsed. The
PULSE command is primarily used for testing purposes.
