Operation
this, it is extremely important that the physical wimg
con-
nections of the protective circuit, includilg connections to
the circuit breaker, match the output connections of the
relay. If the matrixing of the ISGS relay is changed,
double-
check conformance to the wiring of the protective circuit,
and always perform a test to assure that operation of a
pro-
tective function results i1 trippilg of the circLit breaker.
Note:
Do not change matrixing of ISGS relay when the
associated prmary circuit is in service. In order to change
matrixilg, the ISGS relay must reinitialize. Durilg reilitializa-
tion, the ISGS relay does not provide protection.

3.12.2 Alternate Parameter Sets
The ISGS relay supports two sets of protection settings,
denoted as parameter set A and parameter set B. The relay
uses the parameter set designated as the active set in major
address block 7100. The parameter sets may
be
configured
as the system needs dictate. For example, parameter
set
A
may be used for protective settings used in the summer-
tme, whereas parameter set B might comprise the settings
appropriate to
w
ilter, when
low
er ambient temperatures
colid
allow
higher loadilg than i1 the summer. Alternatively,
parameter
set
A might be for normal production periods,
w
ith parameter set B for construction, periodic shutdowns
