Description of air pump controls

The air pumps are controlled in trios based on real demand. One trio is always set as the MASTER
(e.g. M1-3) and the others as SLAVE (e.g. M4-6). The set of three Slave air pumps operate under
the following conditions (see Fig. 20)

-

A waiting period (pressurising to the upper limit) of 1 minute under strong demand and 2
minutes under weak demand

-

Pressure drops below 6.2 bar (SLAVE)

-

Motor failure in the MASTER section

The lower limit settings ROTATE every 50 hours to ensure all the air pumps are evenly loaded.
