20. “MULTIPLY” WORKING MODE
MULTIPLY mode.
External pulses are multiplied by a value set during program session. The pump doses
with a frequency determined by this parameter.
Which parameters must be set ?
MULTIPLY (multiply factor)
TIMEOUT
mode [03]
multiply
multiply
010.00
Key
E
Use this mode if: connected pulse sender water meter produces few pulses and pump
must multiply them for correct dosing activities. See formula below to verify this value.
Minimum value accepted is 001.00. Setting a lower value the pump does not save the data.
Use
“UP”
key to modify the value. Press
“RIGHT”
key to move on next digit.
Press
“E”
key to save data and “
ESC
” to exit to main menu. Otherwise press
“ESC”
to
discard data and exit to main menu.
Use the following formula to find the divider to keep desired concentration.
[ppm] x [K]
( ————————————— ) = N
([imp/l] x
[cc]) x 1000
N - multiplier value to enter into the pump
[imp/l]- pulses/liter from pulse sender water meter
[cc]
- single injection product quantity of dosing pump
[ppm] - part per millions product quantity to dose (gr/m
3
)
[K] - product dilution coefficient.
If obtained “N” is < 1 then install a pulse sender water meter that produces less pulses. Otherwise use the “DIVIDE” mode and divice for 1/N.
It’s also possible to fix the problem trying to decrease product dilution.
Note: before to use this mode please set the “TIMEOUT” parameter as described at page 26.
