4.4.4 Proportional functioning by external pulses 1:N
ADSP9000026
Every time the pump receives a pulse from the water meter it perform the desired
strokes at the programmed frequency.
If the pump receives pulses from the water meter when it's performing a dosing the
pump manages this situation in two modes: proportional or instantaneous.
Instantaneous, the pump gives instantly the remaining strokes at the set frequency and
the extra strokes at the proportional frequency spans on the time of the last two pulses
received from the water meter.
Proportional, the pump save the extra strokes and perform them at the end of the
current dosing at proportional frequency spans on the time of the last two pulses
received from the water meter.
In this functioning mode there are three parameters to set:
Number of strokes to perform.

Setting from 0 to250.
 Frequency of the strokes per minute (SPM).
Setting from 1 to 150 or 180 (depends on the model).
Type of memory proportional or instantaneous.

Example: 1xN (M) = 1x15
The pumps gives 15 strokes at 60SPM frequency every time it receives a pulse from the
water meter.
keys to set the desired values.
Every time that the pump receive "N" pulses from the water meter, the pump performs a
stroke.
In this functioning mode there is only one parameter to set:
Number of strokes to divide (N).

Setting from 0 to 250.
Example: 1:N = 1:15
The pump performs a stroke every 15 pulses received from the water meter.
