4 Hardware Configuration
This chapter explains the device startup and how to config-
ure the basic ISGS relay parameters. The relay must be con-
figured with certain system parameters, such as phase
sequence and frequency. In addition, information regarding
the manner in which the ISGS relay is connected in the
installation must be configured.
All parameter changes require a password. Refer to
Section 3.3 for instructions on how to enter your password.
Viewing parameter settings does not require a password.
Note: The ISGS relay is not password protected
when making parameter changes through
Wisdom software.
Perform parameter changes using steps 1 through 9 of the
standard operating procedure described in Section 3.5.
4.1 Startup
This section describes the content of address block 0000
represented by the initial Power On display and the initial
Power On Meter display.
When the relay is powered on, following a brief hardware ini-
tialization check, the green System LED illuminates and the
LCD shows the contents of address 0000. First, the Power
On display indicates your relay configuration. After approxi-
mately five seconds, the Power On display is replaced by the
Power On Meter display showing two values. Prior to placing
the relay in service, verify that the correct relay configuration
was preloaded at the factory. To return to the Power On dis-
play, press the Direct Addr key and key in 0000 followed by
the Enter key.
4.1.1 Power On Display
The two lines of the Power On display indicate your relay
configuration. Line 1 contains the function address 0000 and
the relay’s firmware version. Line 2 identifies the relay’s cata-
log number which depends on the options you ordered with
your relay (see Figure 4.2 for catalog numbers).
Reading from left to right in Figure 4.1, line 1 shows the
address block 0000 and the ISGS firmware version
ISGS-3V3.00. Line 2 displays the catalog number
D553100VSDF00000. The first character of this number, D,
indicates a 120 VAC power supply, the fourth character, 3,
voltage inputs for energy metering, and the eighth through
eleventh characters, VSDF, indicate Under/Overvoltage pro-
tection, Negative Sequence Voltage protection, Directional
Overcurrent protection, and Under/Overfrequency protec-
tion, respectively.

4.1.2 Power On Meter Display
The Power On Meter display consists of two measured val-
ues. The default setting for Line 1 displays average current,
and Line 2 shows average current demand. The type of
default values displayed can be changed in address block
7000, Operating Parameters, described in Chapter 7.
Figure 4.3 Power On Meter Display
The Power On Meter display is replaced with other informa-
tion anytime an event message is displayed or the LCD is
used to set parameters or check logs. To return the LCD to
the Power On Meter Display, press the Trip Log key followed
by the Target Reset key.
