2.2 Proportional to external impulses
This funtion allows the pump to work in a proportional
way to the impulses received.
Programming “1xN 1xN(M) 1/N“
: Push the
START/STOP button to put the pump in pause and
programming mode. Through the arrow
◄ ►
scroll the
menu untill you can see 1xN 1xN(M) 1/N. Through the
arrow ▼ set the function desired.
1xN Function:
(this function multiples the impulses
received from an external digital signal, ex: water meter.
The pump ignores the arrival of the impulses while working). Fig. B
Programming:
to activate the 1xN function it can go, through the arrow into the corresponding menu and
through the arrows
◄ ►
choose the number of impluses the pump has to realise per every one received. By
pressing again the arrov ▼ you can programm through
◄ ►
the working frequency. Press the ▼ or
▲
arrow to
escape and the START/STOP button to start dosing with the new settings, the display visualizes the option you
have selected (see Fig. B).
1xN (M) function:
this function adds to 1xN the MEMORY function as follows:
- impulse frequency > max frequency pump:
“
the impluses received during work are memorized and used in
a sequence way as long as their exhaustion”.
- impulse frequency < max frequency pump:
“between the impluse received and the following one the pump
distributes uniformly the pumps to avoid dead times”.
Programming:
to activate the 1xN(M) function it can go into the under-menu to act
1xN(M) function and through the arrows
◄ ►
choose the number of impluses made by
the pump for every impluse received. By pressing again the arrov ▼ you can
programm through
◄ ►
the working frequency. Press the ▼ or
▲
arrow to escape and
the START/STOP button to recommence dosing with the new settings, the display
visualizes the option you have selected (see Fig. B).
1/N Function:
(this function divides the impulses received from an external digital
signal, ex: water meter, impulse trasmitters).
Programming:
through the arrows ▼ it can go into the menu to activate 1/N function,
and through the arrows
◄ ►
choose the number of impulse the pump has to receive to
realize one pump. Press the ▼ or
▲
arrow to escape and the START/STOP button to
recommence dosing with the new settings, the display visualizes the option you have
selected (see Fig. B).
2.3 Proportional dosing from milliAmp (mA) current signals
This function enalbes the operator to programm 2x set points with respective stroking
speeds across the whole of the milliamp input signal or a selected band within the
signal range.
Programming:
push the button START/STOP to put the pump in pause and enter
the programming mode. With the arrows
◄ ►
button scroll through the menu untill
mA is displayed.
Press the ▼ arrow to display the mA set point N°1 (it is standard set to 4.0 mA). With
the
◄ ►
arrows increase or decrease the milliamp value required.
Press the ▼ arrow to display the mA set point N°2 (it is standard set to 20.0 mA),
with the
◄ ►
arrows increase or decrease the milliamp value required.
Press the ▼ arrow to display the frequency at set point N°1 (it is standard set to 0
imp/min) and with
◄ ►
arrows increase or decrease the stroking rate required.
Press the ▼ arrow to display the frequency at set point N°2 (it is standard set to 120
imp/min) and with
◄ ►
arrows increase or decrease the stroking rate required.
Press the ▼ arrow to display over mA set point N°1 and with
◄ ►
arrows select
either STOP or CONTINUE. This will either permit or inhibit dosing if the set point is
passed.
