SEL ASCII Protocol and Commands
When you issue the SET command, the relay presents a list of settings one at
a time. Enter a new setting or press
<
Enter> to accept the existing setting.
Editing keystrokes are shown in Table 7.47.
The relay checks each setting to ensure that it is within the allowed range. If
the setting is not within the allowed range, the relay generates an
Out of
Range
message and prompts you for the setting again.
When all the settings are entered, the relay displays the new settings and
prompts you for approval to enable them. Answer Y <Enter> to enable the
new settings. The relay is disabled for as long as one second while it saves the
new settings. The SALARM Relay Word bit is set momentarily, and the
ENABLED LED extinguishes while the relay is disabled.
SHOW Command (Show/View Settings)
When showing settings, the relay displays the settings label and the present
value from nonvolatile memory for each setting class. See Table 7.48 for the
SHOW command settings and Table 7.49 for the command format.
