The pump proportionally doses at a signal of 20-4(0) mA. On the basis of
the factory settings, the pump interrupts dosage at 20mA and doses at the
maximum set frequency when it receives 4 mA. These two values can be
modified during programming. The maximum frequency can be modified
during operation, by pressing the
keys at the same time to
increase the flow, or the
keys to decrease it.

The pump doses in proportion to an external signal (i.e.: impulse launch
counter). With every signal received, the pump makes the programmed
“n” number of strikes. The pump automatically sets the dosage frequency,
adapting it to the time that passes between two successive signals. It is
possible to set the time (timeout) in seconds, beyond which the pump
resets the interval count in order to avoid dosages over excessively long
times. The pump has a memory function, which signals the reception of a
signal during dosage. If set to Off, it merely sends a signal, if set to On it
sends a signal and memorises the impulses, then executes them when it
has finished receiving signals.
The value of “n” can be modified during operation, by pressing the
keys at the same time to increase the flow, or the
keys to
decrease it.
