Siemens Maxum II Service Manual

Increasing the Sensitivity
The sensitivity of the FPD can be increased by reducing the flow of combustion air. Most of
the time, the FPD cannot be ignited with a normal air/hydrogen ratio. If an electronic pressure
controller (EPC) is used for the combustion gasses an event will be written at the factory, which
will automatically adjust the flows during the ignition sequence. To obtain the recommended
flow settings for an analyzer, refer to the custom documentation supplied with that analyzer.
