If a remainder is obtained when dividing by the
factor, then the unit adds the remainders together.
As soon as this sum reaches or exceeds "1", the
pump executes an additional stroke. Therefore on
average during the metering operation, the resul‐
tant number of strokes precisely matches the
factor.
The same applies to the
‘Metering volume’
as to the
‘Factor’
.
Using "Pulse control" you can ideally adapt the pump to the rele‐
vant process, for example in conjunction with contact water meters.

The
‘Batch’
operating mode enables you to pre-select large
metering volumes.
You can only select whole numbers but no fractions as the number
of strokes (figures 1 to 99,999).
You can trigger the strokes using the
[Clickwheel]
if you have
already switched to the
‘Push’
continuous display. You can also
trigger them via a pulse using the "External control" terminal.
The stroke rate can be set in ‘Batch’ operating
mode. It should normally be set to 12,000 strokes/
hour.
The maximum batch time that can be set is 10 000
s.
The maximum possible batch in automatic mode is
the feed rate (in litres or gallons) that the metering
pump can meter in 10,000 seconds at maximum
capacity.
You can also activate the
‘Memory’
function extension ("memory"
identifier). When
‘Memory’
is activated, the pump adds up the
remaining strokes, which could not be processed, up to the max‐
imum capacity of the stroke memory of 999,999 strokes. If this
maximum capacity is exceeded, the pump goes into fault mode.
