9-2 Setting the Relay Date Code 20001006
SEL-351 Instruction Manual
See Section 10: Serial Port Communications and Commands for information on serial port
communications and relay access levels. The SET commands in Table 9.1 operate at Access
Level 2 (screen prompt: =>>). To change a specific setting, enter the command:
SET n m s TERSE
where n = L, G, R, T, or P (parameter n is not entered for the Relay settings).
m = group (1....6) or port (1....3). The relay selects the active group or port if m is not
specified.
s = the name of the specific setting you wish to jump to and begin setting. If S is not
entered, the relay starts at the first setting.
TERSE = instructs the relay to skip the SHOWSET display after the last setting. Use
this parameter to speed up the SET command. If you wish to review the
settings before saving, do not use the TERSE option.
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 9.2.
Table 9.2: Set Command Editing Keystrokes
Press Key(s) Results
<ENTER> Retains setting and moves to the next setting.
^ <ENTER> Returns to previous setting.
< <ENTER> Returns to previous setting section.
> <ENTER> Moves to next setting section.
END<ENTER> Exits editing session, then prompts you to save the settings.
<CTRL> X Aborts editing session without saving changes.
The relay checks each entry to ensure that it is within the setting range. If it is not, an “Out of
Range” message is generated, and the relay prompts for the setting again.
When all the settings are entered, the relay displays the new settings and prompts for approval to
enable them. Answer Y<ENTER> to enable the new settings. If changes are made to Global,
SER, Text, or Port settings (see Table 9.1), the relay is disabled while it saves the new settings. If
changes are made to the Relay or Logic settings for the active setting group (see Table 9.1), the
relay is disabled while it saves the new settings. The ALARM contact closes momentarily (for “b”
contact, opens for an “a”; see Figures 7.28 and 7.29) and the EN LED extinguishes (see Table
5.1) while the relay is disabled. The relay is disabled for about 1 second. If Logic settings are
changed for the active group, the relay can be disabled for up to 15 seconds.
If changes are made to the Relay or Logic settings for a setting group other than the active setting
group (see Table 9.1), the relay is not disabled while it saves the new settings. The ALARM
contact closes momentarily (for “b” contact, opens for an “a”; see Figure 7.28 and 7.29), but the
EN LED remains on (see Table 5.1) while the new settings are saved.
