Programming Of Multiplicator D - Burkert 8021 Notice D'utilisation

4 OPERATION
4.2 Programming of multiplicator coefficient D
The multiplicator D is programmed with the fourth rotary switch (see fig.3). The
correspondance between numbers on the rotary switch and the mutiplicator D is as follows:
Position
Coefficient D 0,01
(liter/pulse)
The Pulse Divider generates a pulse all KxD pulses from the 8020 / 8030 Inline, that is to
say at all Dx1 liter. In case of previous example 1 (K=46,6 puls/l), with a coefficient D=1,
it corresponds to a pulse all 46,6 pulses from 8020 / 8030, that is to say one pulse per liter.
If in the same case D=10, it corresponds to one pulse all 10 litres.
!
The multiplicator D must be confirmed by a reset (short-curcuit on jumper 8).
Essential condition: the product KxD must be greater or equal to 2. If it is not the case,
the Pulse Divider gives no output signal.
An user would like to generate a pulse all n liters (n different of basic multiplicators D). He
just have to programm the following caculated factor K:
K = K
calculated
where D is the first multiplicator greater than n.
Example: to get a pulse all 5 liters with a standard factor K of 46,6 (DN25 PVC), the
following factor K must be programmed:
K =K
calculated standard
Here D=10.
