For

identified
with
a
"
T
"
,
located
at
lower
left
of
stationary
contact
block
,
the
index
mark
on
the
movement
frame
will
coincide
with
the
"
0
"
mark
on
the
time
dial
when the
station
-
ary
contact
has
moved
through approximately
one
-
half
of
its
normal deflection
.
Therefore
,
with
the
stationary
contact
resting against
the
backstop
,
the
index
mark
is
offset
to
the
right
of
the
"
O
"
mark
by
approximately
.

.
The
placement
of
the
various time dial
positions
in
line
with
the
index
mark
will
give
operating
times
as
shown
on
the
respective
time
-
current
curves
.
For
double
trip
relays
,
the
follow
on
the
