3.1
Overview
This
section explains how to operate the
ISGS
relay.
COn-
tained
1
n
th1
s
sect1
on are the keypad explanation,
relay
menu
structure, and the various parameter selections available
for
system
configuration.
To configure
the
relay the user must be granted access to
the protection parameters, which
requires
the correct
pass-
word. Access to the parameters
will
allow the user to
change configuration and protective
function
settings. lf the
user
"saves"
the changes, the
relay
will
update its
internal
parameter database and implement the new
parameters.
1f
the changes
involve
device configuration or
matrixing
(address
blocks 1000 through
1200,
or 6400),
rather
than
just
a parameter change, the
relay
can
require
up to 30
sec-
onds to
re-initialize.
This
will
temporarily
leave the circuit
unprotected.
Therefore, do not change the matrixing
{address block 6400) or the device
configuration
{address
blocks 1000 through 1200)
wh~e
the
relay is
in
service.
3.2
Data
Ports
The
relay
provides both RS -232 and, optionally, RS
-485
data interfaces. The RS-232 interface is located on the front
panel
of the relay and access to this
feature
is via a DB-9
connector. Connection to the
optional
RS-485
interface is
accomplished via pins 48,
49,
and 50 on the
rear
panel. Use
of either of these data interfaces
will
allow the same
level
of
access to the system as the
front
panel
keypad.
This
man-
ual
covers
only
keypad
operations.
If
you
require more
infor-
mation
about the data interfaces,
refer
to the appropriate
software
manual
(e.g
.• WinPM software or Wisdom
soft-
ware).
