ppM FUNCTIONING DESCRIPTION
The formulas used by the microcontroller are the following:
- 1xN : N= (ppM * L/i) / (cc/iniez * Conc% * 10)
- 1/N : N = (cc/iniez * Conc% * 10) / (ppM * L/i)
In special cases when the result is very high, for example:
Rev 3.0
PROGRAMMING OF THE ppM FUNCTIONING
The pump receives the pulses from the water-meter and automatically calculates the dosage to
be performed according to the value of the programmed ppM, the concentration of the product,
liters of water that pass for each pulse trough the water-meter and quantity of product dosed for
each injection of the pump. All these parameters are set during programming, as in the following
section.
PROGRAMMING
Push and quickly release CAL button and scroll the menu using
+ and – buttons till the display shows "Function Type". Push
CAL to enter the submenu and then by pressing + and – button
choice " Function Pulse" and confirm pressing CAL.
Push + and – button to choice "Pul.Type ppM." and confirm by
CAL .
Push + and – button to choice the value of desired ppM. Confirm
by CAL .
Pushing + or – button choice the value of the % concentration of
the chemical. Confirm by CAL .
Push + and – button to choose the liters of water passing through
water-meter per each pulse and confirm by CAL .
Example: a 4 pulses / liter water-meter should be set to the
value of 0.25 L / i (result of the calculation 1: 4)
Possible values:
1imp = 0.25 / 0.5 / 1 / 2.5 / 5 / 10 / 25 / 50 / 100 / 250 / 500 / 1000
/ 10000 liters.
Push + and – button to choice the quantity of cc dosed for every
single injection.Confirm by CAL .
Push ESC button to esc the menu and go back in measure with
the ppM functioning just programmed.
