    OPERATION 16. SWITCHING THE COMPRESSOR After the pressure switch (6) is activated and circuit breakers FA13 (11) and FA14 (12) are turned to position I, the compressor air pumps sequentially come online (the air pumps in the second column or shelf react with a 2 s delay). Circuit breaker FA13 (11) functions as the main switch. The air pumps switch on (at ≤6 bar) and off (at ≥8 bar) automatically and are controlled by the LOGO! (13) controller and the pressure switch (6) based on compressed air usage.
