Cycle counters [ct1] and [ct2]
The ejector is equipped with two counters. Counter 1 is increased with each valid pulse on
the suction signal input, and therefore counts the number of suction cycles in automatic
mode. Counter 2 is increased with each switch of the suction valve. The switching frequen-
cy of the air-saving function can then be determined from the difference between counters 1
and 2.

Counter 1
