The advantage is that you can
set different advance for each
output. This way it is possible to
switch off a pump and later
close the valve.
Binary outputs have 4 options
for setting in batch mode. They
set or from outside with the
help of module E in Batch Stop
mode. During this phase there
is no reaction to external signal
Batch Start. If there is no any
preset outputs' advance, after
flowing of the set batch volume
comes switching to phase 0
(Stop). Outputs will send signal
for batch stop (switch off pump,
close valve). Because of the
late reaction to the output signal
a partial overflow of the set
batch volume will take place
and display will show negative
volume. That's why it is suitable
to send a signal for batch stop
in advance as it is described
below.
Phase 3 - Finish
In practice we need to send a
signal for batch stop in ad-
vance. It is mainly because of
the inertia of the technical
equipment (valves, pumps).
Phase 3 represents time when
one of the outputs have sent in
advance signal for batch stop.
According to the ability to fore-
cast exactly the advance, the
batch can slightly overflow
which means to go to phase 0
or the batch will not finish and
will go to phase 3. In this case it
is possible to go to phase 0 by
choosing Reset or from outside
with the help of module E in
Batch Stop mode. In the same
time takes place presetting of
the volume batch accroding to
the preset value. Second possi-
bility is to start new batch
choosing restart or from outside
with the help of module E in
Batch Start mode.
The binary outputs in batch
mode enable setting of the ad-
vance by volume when the out-
put is activated, if the remaining
batch volume is smaller than
the preset volume advance.
Second possibility is to set time
advance when the flowmeter's
logic calculates what time re-
mains to the end of the batch
according to the actual flow.
Both possibilites can be com-
bined. Output reacts to the

can indicate condition when
runs the batch (phase 2) or to
sent a pulse for batch finish/
interuption. Pulse length can be
set from 10 ms up to 2550 ms,
step 10 ms. Both output modes
can work in both polarities.
