Internal cycle counters [ct1], [ct2], [ct3]
The ejector system has various internal counters.
Counter 1 is incremented with each external signal on the control line
SUC-
TION
and thus counts the suction cycles. In the case of ejectors with pulse
valves, each valid suction pulse is counted.
Counter 2 is incremented each time the internal suction valve changes state.
The difference between Counter 2 and Counter 1 can thus be used to find out
how often vacuum air saving function has been executed.
Counter 3 counts the number of faults which caused the diagnostic output to be
activated.
The counters can be reset with the aid of the menu.
