HL 356 Demo unit, gas burner
The HL 356 demonstrates the basic functioning of an original gas burner and its typical behaviour in case of faults. Standard industrial components are used. All operating states of the burner are simulated, allowing this demo unit to be operated without gas and flames. The unit is therefore totally non-hazardous and has no gas or waste gas lines. On the front panel is a graphical representation of the controller unit connection. Important electrical monitoring points (controller unit terminals) on the burner are accessible for fault analysis using lab jacks and bridges on the front panel. Faults can thus be checked either during operation under voltage or with no voltage as an isolated component.
