Carry out soundness test after each service and fault rectification. 2.4 Alterations to the construction of the equipment All conversions require written approval from Max Weishaupt GmbH. No additional components may be fitted, which have not been tested for use with the equipment.
Installation and operating instruction Combustion Manager W-FM 50 3 Product description 3 Product description 3.1 Function 3.1.1 Burner Control A burner control for oil and gas burners is integrated in the combustion manager. It controls the sequence of operation, monitors the flame and communicates with all components.
Installation and operating instruction Combustion Manager W-FM 50 3 Product description 3.1.3 Valve proving The valve proving gas pressure switch checks if the valves are tight. It signals the combustion manager if the pressure increases or decreases to an impermissible level during valve proving.
Installation and operating instruction Combustion Manager W-FM 50 3 Product description 3.1.5 Calculation A calculation can be triggered in modulating commissioning, if P1 and P9 are pro- grammed. During a calculation, a straight line is generated from the operating point displayed to P1 or P9.
Installation and operating instruction Combustion Manager W-FM 50 3 Product description 3.1.7 Referencing the actuator In operating phase Ph10 (Home Run) the combustion manager references the actuators, whereby the actuator drives over a reference marker.
