Setting Entry Error Messages
To change a specific setting, enter the command shown in Table 6.5.
Setting Entry Error Messages
As you enter relay settings, the relay checks the setting entered against the
range for the setting as published on the relay setting sheet. If any setting
entered falls outside the corresponding range for that setting, the relay
immediately responds
Out of Range and prompts you to reenter the setting.
In addition to the immediate range check, several of the settings have
interdependency checks with other settings. The relay checks setting
interdependencies after you answer
Y to the Saves Settings? prompt, but
before the settings are stored. If any of these checks fail, the relay issues a
self-explanatory error message, and returns you to the settings list for a
correction.
Table 6.5 SET Command Format
SET n m s TERSE
where:
n is left blank or is D, G, L, F, R, M, or P to identify the class of settings.
m is blank (1) or is 1, 2, or 3 when n = G or L for group settings.
m is left blank or is F, 1, 2, 3, or 4 when n = P.
s is the name of the specific setting you want to jump to and begin setting.
If s is not entered, the relay starts at the first setting (e.g., enter 50P1P to
start at Phase Overcurrent Trip level setting).
TERSE instructs the relay to skip the settings display after the last setting.
Use this parameter to speed up the SET command.
If you want to review the settings before saving, do not use the TERSE
option.
