Low gas pressure before fuel
changeover
Selected fuel gas pressure is too low and therefore not ready to
run
• Warning
• Check selected Fuel Gas Pressure
• Check gas pressure sensor wiring
Selected fuel cannot be run
Selected fuel is not fully commissioned
• Warning
• Check that selected fuel is properly commissioned for Dual Fuel Output Mode
• Check if FGR and/or Golden Start points are optioned but not commissioned
*When option 12 is set to 3 for trim and combustion limits, the combustion limits are evaluated once per trim cycle.
A combustion limit error will occur if the current exhaust value has crossed the combustion limit for the number
of trim cycles set in parameter 17 (the default value is 3 cycles).
