Start Sequence
Stand-by
•
No fault is present.
The system is waiting for local or remote start signal.
Feed Gas Supply
•
Start of the air preparation system (optional).
•
The system is waiting for required inlet feed gas pressure.
If the pressure is not higher than the start level after 30 minutes,
the system stops and a fault message is generated.
•
The system is waiting for feed gas dew point (option).
If the dew point is above start level, the system purges feed gas via
the dew point purge valve (dew point > -56 °C atm).
If the dew point is not lower than the start level after 90 minutes, the
system stops and a fault message is generated.
•
The system is waiting for generator pressure.
After the system has been switched on for the first time or after a
fault in the safety chain, the system carries out the process:
pressure build-up generator.
