3.4 Menu
The ISGS relay menu (or memory map) is organized in a hier-
archical structure that is made up of address blocks and
addresses. The first level consists of address blocks. Each
address block represents one complete function or two
related functions and is identified by a unique four-digit num-
ber ending in two zeros (for example, 1500). Refer to
Figure 3.1.
The second level consists of individual addresses confined to
an address block. Each address represents a part of a func-
tion—the changeable parameter—or the measured value of
a displayed parameter. The parameter is identified by a
unique four-digit number that consists of the first two digits
of the address block and two digits indicating the parame-
ter’s number within the address block (for example, 1502).
Refer to Figure 3.1.
Figure 3.1 Example of Menu Structure Displaying Address
Blocks with Two Related Functions, an Individual Function,
and an Unavailable Function.
A complete ISGS relay menu with parameter listing is pro-
vided in Appendix C. The various parameter settings are
shown in the respective section describing the complete
function.
Only certain protective function parameters have two set-
tings. All A settings are grouped under parameter set A, and
all B settings are grouped under parameter set B. Each
parameter set automatically includes all the regular parame-
ters that can be programmed to only one setting at a time
and, therefore, apply to both sets. Examples are protective
function enable settings and matrixed output contacts such
as waveform buffers and blocking. For more information on
parameter sets, refer to Section 6.11.

The LCD identifies functions that include parameters config-
urable for A and B settings by preceding the function’s
address block number with the letter A or the letter B,
depending on which parameter set is currently displayed.
Refer to Figure 3.2.
Figure 3.2 LCD Display of a Function that Includes
Parameters Configurable for A and B Settings.
In addition, when scrolling through the individual parameters
of an ISGS relay, the LCD identifies each parameter that is
configurable for A and B settings by preceding the parame-
ter’s address number with the letter A or the letter B,
depending on which parameter set is currently displayed.
Refer to Figure 3.3
Figure 3.3 LCD Display of a Parameter that is Configurable
for A and B Settings
When accessing the ISGS relay menu through the keypad,
the Arrow keys allow scrolling through all available functions
and parameters. If an option is not installed, the LCD only
displays the address block that is reserved for this option. In
this case, second level addresses are not available.
3.5 Standard Operating Procedures
Before attempting to display or configure any of the relay
data, ensure that the relay has control power which is indi-
cated by the system LED (green) being lit.
The steps for displaying data, configuring parameters, saving
data, and switching to the alternate parameter set for either
display or configuration are described in detail in Table 3.1,
Standard Operating Procedures.
