Manual Dosing; Pulses Dosing - VERDER VP2-HT PULSE Manual De Regulación

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.
Manual dosing:
A) Deactive cycle
B) Active cycle
1. t = t : Istant of switching on of
1
the pump or istant of receiving
the enable signal
2. t = t : Istant of switching off of
2
the pump or interruption of the
enable signal

PULSES DOSING

For every N pulses received from the water-meter the pump doses the ml of chemical set in mL Dos. The dosing flowrate
is programmed in %Flowrate. The memory function allows to memorize all the impulses coming from the watermeter
while the pump is dosing and to perform the related dosing immediately after.
NB: it is important to define the flowrate of the pump in the Calibration menu.
