The ventilators are controlled by flow monitors. If no air flow is detected
after a short waiting time has elapsed, the system is switched off and a fault
is reported. You acknowledge this by pressing the stop switch.
In addition to the flow monitors, the ventilation monitoring system requires
an evaluation circuit with a number of switching devices. The evaluation
circuit can be replaced by a single LOGO! module.
