MANUAL DOSING
There are 2 manual dosage types:
1) With the Cycle parameter deactive (
Cycle [dea]
) the dosage is constant at the defined flowrate (% Flowrate)
2) With the Cycle parameter active (
Cycle [act]
) the dosage is constant at the defined flowrate (% Flowrate) but is
also cyclical with programmable ON (Ton) and OFF (Toff) times. Furthermore, the dosing can be activated after a
programmable delay (Td) when the pump is switched on or when the enable signal is received. The enable input
is optional and therefore may not be present. See the Connections diagram on page 18. NB: if the optional enable
is present, you can choose whether to activate it or not in the SET UP menu; page 20.
In the menu
Dosing
, select by the cursor "Manual" and
press
ENTER
.
Use the ▼▲ buttons to select the parameter to be
changed and press
ENTER
.
In the figure on the left you can see the factory
parameters with cycle disabled and with active cycle.
Td
:this is the time in seconds (from 0-9999sec) that the
pump waits before dosing the chemical after its
switching on or after receiving the enable signal.
Ton
:this is the time in seconds (from 0-9999sec) of
dosing
Toff
: this is the time in seconds (from 0-9999sec) of
stop dosing.
Manual dosing:
A) Deactive cycle
B) Active cycle

mA DOSING
This dosing is proportional to the mA current received from the input. The proportionality range and the flowrate can be
freely programmed.
In the menu
Dosing
, select by the cursor "mA" and
press

whenever necessary to confirm the
change.
If you want to esc programming and return to
