The
total
power
meter
function
calculates
the
sum
of
the
active
energy
of
all
channels
at
which
the
power
meter
function
was
activated.
The
object
can
be
selected
as
well
to
Wh
as
to
kWh.
Via
the
parameter
“Sending
object
value”
can
be
determined,
if
the
object
sends
its
current
value
only
on
request
or
in
adjustable
time
intervals.
Furthermore
it
can
be
adjusted,
if
the
power
meter
shall
hold
its
current
value
or
if
they
shall
set
to
zero
again
after
a
download.
The
total
power
meter
has
in
contrast
to
the
power
meter
for
the
single
channels
no
reset
object.
The
total
power
meter
function
calculates
always
the
sum
of
all
single
channels.
So,
a
reset
of
all
single
channels
causes
automatically
a
reset
of
the
total
power
meter.

Monitoring
exceedance/deviation
of
load
An
observation
of
the
load
can
be
activated
for
every
channel
for
an
exceedance
of
a
comparable
worth
as
well
as
for
a
deviation
of
this
worth.
The
total
current
measurement
can
only
observe
a
exceedance.
The
possible
settings
are
shown
at
the
following
illustration:
