• The Plasma RF cable came off or the cables are defective.
• Malfunction of the Shunt condenser and Series condenser (Faulty XYZMN
Board is also probable).
• The power cable to the plasma RF generator comes off.
• Faulty plasma RF generator.
1204 Error: Turbo is not slowing at Ar purge.
During the argon purge, the number of revolutions of the turbomolecular pump
did not go below the limit within the prescribed time. The power of the
turbomolecular pump was forcibly switched off (When the instrument is
changing from Standby Mode to Shutdown Mode).
Check the number of revolutions and the current of the turbomolecular pump.
After detecting this error, the display of the number of revolutions and the
current of the turbomolecular pump will be incorrect. To check the number of
revolutions and current, start from Standby mode again.
During the argon purge, if the number of revolutions of the turbomolecular
pump does not go down, the following causes are inferred.
• Faulty turbo pump controller.
• Faulty System I/O Board.
1205 Error: Turbo is not slowing at Air purge.
During the air purge, the number of revolutions of the turbomolecular pump
did not go below the limit within the prescribed time. The power of the
turbomolecular pump was forcibly switched off (When the instrument is
changing from Standby Mode to Shutdown Mode).
Check the number of revolutions and the current of the turbomolecular pump.
After detecting this error, the display of the number of revolutions and current
of the turbomolecular pump will be incorrect. To check the number of
revolutions and the current, start from Standby mode again.
During the air purge, if the number of revolutions of the turbomolecular pump
does not go down, the following causes are inferred.
• Faulty turbo pump controller.
• Faulty System I/O Board.
1206 Error: Turbo speed did not drop down following purge cycle.
After the purge, the number of revolutions of the turbomolecular pump did not
go below the limit within the prescribed time. The power of the turbomolecular
pump was forcibly switched off (When the instrument is changing from
Standby Mode to Shutdown Mode).
Check the number of revolutions and the current of the turbomolecular pump.
After detecting this error, the display of the number of revolutions and the
current of the turbomolecular pump will be incorrect. To check the number of
revolutions and the current, start from Standby mode again.
