ADDITIONAL FEATURES WITH AIR PUMP
Operation principle
Standard Version
The Air Pump technology generates a re-mix of the acid inside the battery by a constant delivery of air
pumping.
The battery charger controls the air pump by an auxiliary contact (generally AUX1).
An air injection cycle along all the charging period is held as per requirements of the battery
specifications.
Pressure sensor version
Further to the characteristics of the standard version it is also available an electronic circuit equipped with
an air pressure sensor.
At the beginning of the charging process, the sensor verifies that the pressure in the circuit is included in
a definite window between a minimum and a maximum value (look at the following table). When an
anomaly occurs the battery charger will modify the charging factor by effecting a charge without detecting
and controlling the Air Pump
