Example: If I have connected my pump to a water-meter of the CB1 range able to provide pulses (1 pulse/l), and I have
selected n=8, this will mean that for every pulse received from the water-meter my pump will provide 8 strokes. That is to
say, for each litre of water passing through the water-meter the pump will dose 8 strokes.
Once the value has been set, it must be confirmed by pressing the Enter key. Then it is possible to go on to set the
Memory function (see below).
The indication OFF (or ON) will appear on the display, to signal that the Memory function has been disabled (or
enabled). The Memory icon will flash.
The arrows keys or can be used to change the indication (ON or OFF).

This function consists of storing any external pulses in the event that the pump was not able to provide all the
programmed strokes. These pulses are stored by the microprocessor, up to a maximum of 65,535, and the “missing”
strokes are returned as soon as possible, for example when no more external signals are received by the pump
(example: no more water is running through the water-meter).
- Memory function set to OFF (Memory icon extinguished)
The pump does not store the excess pulses, however it does signal a situation of under- dosing, causing the display to
indicate ALL2. This will disappear as soon as the set parameters are reinstated.
- Memory function set to ON (Memory icon illuminated)
As soon as the pump starts to store the excess pulses, the Memory icon will start to flash, until all the corresponding
strokes have been returned.
If the storage capacity is exhausted (more than 65,535 pulses stored) the alarm will also be activated (the Memory
icon will continue to flash)
Dosing of the pulses that have been stored can be interrupted by pressing both the and keys at the same time.
Dosing of the pulses will then be resumed starting from the next incoming external signal (example: if the water starts
to run through the water-meter again).
WARNING: If the dosing pump is switched off, any pulses stored will be deleted.
Press Enter to confirm the selected settings and exit from programming. The indication Prog will appear on the display for
about one second, after which the value of previously set flow rate will appear.
To start the pump press the START/STOP button (the Stop icon will be extinguished). While the pump is working on the
display will appear the number of strokes the pump is dosing (count down).
WARNING: The pump may stop due to a possible pump-stopping signal given by the level probe (Level icon illuminated and
Alarm LED steady on). Please see the section on Checking the level of liquid to be dosed.
