UNCTIONING FEATURES
Constant
The pumps can work in four constant modes:
5. Capacity
When powered, the pump doses in constant mode at the selected frequency.
6. Period
When powered, the pump doses in constant mode at the selected frequency and for “X” amount of
time (sec. or min.) set. (ex: 10 sec at 90% frequency rate) This cycle is repeated every time the
pump is powered.
7. Quantity to dose
It is necessary to calibrate the pump initially (flow rate). When powered the pump doses a fixed
amount of product at the set time (ex. 20 ml. in 10 min.), then pump stops. This cycle is repeated
every time the pump is powered.
8. Cyclical
When powered the pump works in a time/cycle mode; (ex. it doses 10 seconds every 10 minutes)
at the set frequency.
Proportional 1xN
The pump for each pulse received on the “
INPUT
PULSE
” will perform “N” strokes at the set frequency.
Proportional 1xN (M)
The pump for each pulse received on the “
INPUT
PULSE
” will perform “N” strokes and can save the
extra strokes.
This mode can be programmed as follows:
3. Proportional: 1xN (M) Prop.
the pump save the extra strokes and perform them at the end of the current dosing at a
proportional frequency span on the time of the last two pulses received from the water meter.
4. Instantaneous: 1xN (M) Ist.
The pump gives instantly the remaining strokes at the set frequency and the extra strokes at the
proportional frequency span on the time of the last two pulses received from the water meter.
Proportional 1:N
The pump performs 1 stroke
every “N” pulses received by the water meter on the “
INPUT
PULSE
” .
Maximum frequency 30 Hz.).
PPM
The pump calculates automatically the strokes to inject for each pulse received from the water meter.
It is necessary to calibrate the pump initially and set the following parameters: the desired PPM, the type of pulse
water meter used (litres per pulse) and the concentration of the chemical product (in %).
Proportional in current
– mA
The pump doses proportionally to a 4-20 mA signal received on th
e “
INPUT
mA
”.
Proportional in Cl- J (A
– J Probe)
T
he pump doses proportionally by Chlorine reading (range
0,01- 5,00 ppm
) on Chlorine A- J probe input
.
Timer
The pump can be controlled by a daily or weekly timer and it’s possible to program up to 7 ON/OFF
operations per day.

THER FUNCTIONING FEATURES
Level alarm
The pump goes in low level alarm when on the “
INPUT
LEVEL
” there is a dry contact (ON/OFF).
This alarm has a filter of 5 seconds.
