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. See Table 9.1).
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: Set Command Editing Keystrokes

<CTRL> X

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 or Text settings (see Table 9.1), the relay is disabled while it saves the new settings. If
changes are made to a Port setting, the relay is not 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” contact; see Figure 7.26) 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.
