Cold

>N<
Pulse
inputs
A
and
B
of
MULTICAL®
403
can
be
used
for
cold
water
leakage
monitoring.
Basically,
however,
cold
water
leakage
monitoring
is
only
active
on
input
A,
unless
otherwise
agreed
with
the
customer.
When
MULTICAL®
403
is
used
for
leak
monitoring;
the
sensitivity
is
determined
by
the
configuration
of
the
N
‐
code.
Leakage
monitoring
is
measured
over
a
period
of
24
hours.
The
N
‐
code
defines
the
resolution,
by
which
the
24
hours
are
divided;
48
intervals
of
half
an
hour,
24
intervals
of
one
hour
or
12
intervals
of
two
hours.
If
the
meter
registers
minimum
one
pulse
during
each
of
these
intervals
over
the
full
period,
info
code
8,
which
indicates
leakage,
is
activated.
The
info
code
is
not
activated
until
after
the
24
‐
hour
period,
however
it
is
reset
again
as
soon
as
the
meter
registers
an
interval
without
pulses.
The
table
below
shows
the
three
available
N
‐
codes.
Upon
receipt
of
order
the
N
‐
code
is
configured
at
2
by
default
(unless
otherwise
informed
by
the
customer).

Pulse
outputs
C
and
D
>PP<
MULTICAL®
403
has
2
pulse
outputs
(C
and
D)
which
are
placed
on
the
communication
modules
(see
paragraph
11
for
further
details
on
modules).
The
pulse
outputs
provide
output
from
selected
counter
registers,
which
are
determined
by
the
selected
country
code.
As
the
meter
has
two
pulse
outputs,
it
is
possible
to
provide
output
from
two
of
the
following
counter
registers
via
pulse
outputs
C
and
D
respectively:
E1
(Heat
energy)
E3
(Cooling
energy)
V1
(Volume)
Note:
As
selected
counter
registers
are
configured
by
country
code,
configuration
cannot
be
changed
after
delivery.
Pulse
outputs
are
by
default
configured
with
the
following
registers:

The
resolutions
of
pulse
outputs
always
follow
the
least
significant
digit
in
the
display,
which
is
determined
by
the
CCC
‐
code
(see
paragraph
3.2.3)
e.g.
at
CCC=419:
1
pulse/kWh
and
1

.
Pulse
outputs
C
and

are
placed
on
selected

modules.
