2.2.2
Sum value function
The
T060Ei
the
double
channel
weighing
version
(D
option)
foresees
the
possibility
to
handle
the
sum
value
of
the
two
channels.
The
value
can
be
displayed
both
pushing
and
in
association
with
one
or
more
threshold
relays
alarms
(see
chapter
2.5).
In
case
of
systems
with
capacity
or
different
unit
measure,
the
operator
mus
realign
the
value
to
the
same
unit
measure,
deciding
which
of
the
two
channels
must
be
taken
as
reference
channel.
I.E.:
Channel
1F.S.
10.00t
and
channel
2
1000kf
F.S.
considering
channel
1
as
reference
channel(parameter
PRIOR
),
we
should
return
the
channel
2
to
a
display
in
t.
In
order
to
get
this
the
T060E
with
parameter
MULTIP
allows
dividing
or
multiplying
the
channel
value.
In
our
example
dividing
by
1000
the
channel
2
value
is
displayed
as
for
channel
1
in
t.
According
to
different
systems
capacities,
multiplying
or
dividing,
it
is
possible
to
sum
values
with
the
same
measure
unit.
2.2.3
Management of the zero
The
external
inputs
can
be
used
to
reset
potential
zero
derivatives
or
deviations
relative
to
the
weighing
system.
The
AZM
limit
is
valid
in
both
ways,
therefore
the
actual
field
is
‐
100.0%
.+100.0%.
The
input
is
active
on
the
closing
panel.
Weight
resetting
is
carried
out
after
conversion
and
linearization
operations
which
are
not
influenced,
causing
a
vertical
translation
of
the
transmitter’s
response
curve.
Zeroing
affects
all
transmitters’
functions:
display,
serial
transmission,
analogue
output
and
threshold
management
are
all
linked
to
the
correct
weight
value.
The
reset
value
is
lost
if
the
equipment
is
turned
off.
The
non
‐
reset
total
weight
value
can
be
checked
locally
by
pressing
key
DEC:
by
keeping
this
key
pressed,
the
instrument
displays
the
total
weight
value.
