GEL DOSAMATIC PP Installation, Use And Maintenance Manual page 51

Which parameters must be set?
DIVIDE (division factor)
Enter the multiplication value according to the type of water meter with impulse
sender the pump is fitted with. It is recommended to use this mode if the water
meter produces few impulses (i"P" "CTFI") and it is necessary to divide them to
let the pump complete dosing properly.
Minimum value accepted is 001.00. If you set a lower value, the pump does not
accept the signal and does not save data.
Use "UP" key to modify the entered value.
Press "RIGHT" key again for next digit (unit).
Press "P" key to save the entered value and "ESC" to exit to main menu, or only
press "ESC" to exit without saving.
How to calculate the multiplication value?
N division value to be set
[imp/l] impulses/litre from water meter with impulse sender
[cc] quantity of product dosed per single injection (expressed in cc) of the metering pump used
[ppm] product quantity to dose expressed in parts per millions (gr/m
[K] dilution coefficient of the product to dose 0<K<=1. Pure product K=1
If N value, previously calculated, is < 1, it is necessary to install either a water meter with impulse sender
that produces more impulses per litre or a metering pump with a higher flow rate per unit (CC). It is possible
to solve the problem by setting the pump to "MULTIPLY" mode and multiply by 1/N. In some particular
applications it is also possible to fix the problem by decreasing the dilution factor of the product to dose.
Should the quantity dosed be higher than the one you need, just increase the division factor (N) set in the
knob on the metering pump.
5.3 "MULTIPLY" working mode
The impulses supplied by a water meter connected to the pump are divided by the value set during
programming. The pump doses with a frequency set by this parameter.
Which parameters must be set?
MULTIPLY (multiplication factor)
TIMEOUT
Enter the division value according to the type of water meter with impulse sender
the pump is fitted with. It is recommended to use this mode if the water meter
produces few impulses (i"P" "CWFA") and it is necessary to multiply them to let
the pump complete dosing properly.
Minimum value accepted is 001.00. If you set a lower value, the pump does not
accept the signal and does not save data.
