1150 Error: Penning gauge (AN) fails to strike.
The Penning gauge cannot strike.
Check the pressure of the analyzer chamber. The following causes are inferred.
• The Penning gauge electrode is dirty.
• Faulty Penning gauge.
• Fault of the System I/O Board.
1151* Error: Turbo Pump (A, I) not at desired speed during penning gauge
turn ON.
When making a retry of the Penning gauge, the number of revolutions of the
turbomolecular pump (A/I) was not within the prescribed range.
Shutdown the instrument and then the vacuum turns ON.
1151* Error: Turbo Pump not at desired speed during penning gauge turn
ON.
When making a retry of the Penning gauge, the number of revolutions of the
turbomolecular pump was not within the prescribed range.
Shutdown the instrument and then the vacuum turns ON.
1152 Error: Backing solenoid valve (SVBK) did not open.
When the instrument transits from Shutdown mode to Standby mode, it failed
to open the backing solenoid valve (SVBK). (When the instrument is changing
from Shutdown Mode to Standby Mode).
Check the operation of the backing solenoid valve (SVBK). The following causes
are inferred.
• The backing solenoid valve connector came off.
• The backing solenoid valve is defective.
• There is a fault in the System I/O Board.
1153 Error: Interface solenoid valve (SVIF) did not open.
When the instrument transits from Standby mode to Analysis mode, it failed to
open the interface solenoid valve (SVIF) (When the instrument is changing
from Standby Mode to Analysis Mode).
Check the operation of the interface solenoid valve (SVIF). The following
causes are inferred.
• The interface solenoid valve connector came off.
• The interface solenoid valve is defective.
• There is a fault in the System I/O Board.
