An industrial wafer baking machine is complex in terms of control technology. The ignition process of the gas-fired long-tube burner alone comprises 20 individual steps. Numerous other process steps are added as the baking process continues. The wafer machine specialist Franz Haas-Waffelmaschine therefore decided in favor of a flexibly configurable, safe miniature control system that can be used to monitor and control not only the functional safety but also the burner control and thus the entire safety technology of the baking machines.
