4.2.2 Programming of multiplier coefficient D
The multiplier D is programmed with the fourth rotary switch (see Fig. 4.1). The
correspondance between numbers on the rotary switch and the mutiplicator D is as follows:
Position
Coefficient D 0.01
(litre/pulse)
The Pulse Divider generates a pulse all KxD pulses from the 8030. that is to say at all Dx1
litre. In case of previous example 1 (K=52,91 puls/l), with a coefficient D=1, it corresponds
to a pulse all 52,91 pulses from 8030. that is to say one pulse per litre. If in the same case
D=10. it corresponds to one pulse each 10 litres.
Confirm the multiplier D by a reset (short-circuit on jumper 8 - Fig. 4.1 ).
!
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.
In order to generate a pulse all n litres (n different of basic multiplicators D).
It is necessary to program the following caculated factor K:
K = K
calculated
where D is the first multiplier greater than n.
Example: to get a pulse all 5 litres with a standard factor K of 52,91 (DN25 PVC), the
following factor K must be programmed:
K =K
calculated standard
Here D=10.
