•
Environmental conditions: indoors, maximum altitude 2000 m, room temperature from 5 ° C to 40 °
C, maximum relative humidity 80% up to a maximum of 31 ° C (decreasing linearly until it is reduced to
50% at 40°C)
•
Classification with respect to protection against direct contacts: CLASS I, the equipment is supplied
with a protective conductor
Reference Standards
The dosing pump complies with the following directives:
•
2006/95/EC: "Low tension"
•
2004/108/EC: "Electromagnetic compatibility"
Operating functions:
When first turned on the user can choose between different operation modes as best illustrated in the
following chapters.
In general, the pump can operate in the modes specified in the following table.
Modes
Description
MANUAL
The pump doses in a continuous manner up to a maximum of 300 injections
per minute (the number of injections / minute changes as a function of the
maximum capacity). The flow rate is adjustable by the user in the
programming phase.
PROPORTIONAL
Meter
In this mode the pump receives impulses from an external meter, the pulses
are managed in one of the following operational functions:
•
1 x N: each impulse of the meter corresponds to the N injections of the
pump.
•
1 x N(M): each meter impulse corresponds N of the pump, with storage
for up to 4 * N impulses from the meter during dosing
•
1 / N: each N impulses of the meter corresponds to a single pump
impulse.
•
ml x imp: at each meter impulse the pump dispenses a pre-determined
amount of additive in millilitres.
•
l x imp: at each meter impulse the pump dispenses a pre-determined
amount of additive in litres.
PROPORTIONAL
ppm - ml x m3 from
the meter
The pump doses directly in ppm (Parts Per Million) or else in ml x m3
(millilitres per cubic metre).
The device automatically carries out all calculations necessary to
provide the required concentration.
