NOTE:
lf control power is lost while you are
changing the Address or Baud
Rate
(i.e.: while
you
are
still holding in the
"Trip Reset" push button), the display will
go blank and when the control power
is
restored, the Trip Unit will still retain the
previous Address and Baud Rate values,
as
if
you had not been trying to change
them.
NOTE: As shown in Figure 10-4, there
is a
space
to record both the
INCOMM Address and
the Cell Number (to identify the Breaker
location within the assembly) to the left
and below the display window. Because
Trip Units and Circuit Breakers of the same
rating are interchangeable, if more than
one has been withdrawn
for
maintenance
at one time, it is critical that each unit be
returned
to
its conect Cell location so that
the circuit has
the correct Address.
For example, if
two identical Breakers (one
whose Trip Unit Address is 001 and the
other whose Address is 100) were
switched, the INCOMM communications
system will be confused and the informa-
tion coming from the 001 Trip Unit, as well
as
the commands going to the
001 Trip
Unit, will actually involve the
1
00 circuit,
and vice versa.
