Agilent 7500 Series ICP-MS Hardware Manual 5-25
Check the number of revolutions and the current of the turbomolecular pump
(A), vacuum pressure (AN), vacuum pressure (BK), and S75 power voltage. The
following causes are inferred.
• A rise in the vacuum pressure.
• The connector of the turbomolecular pump (A) came off.
• Faulty turbomolecular pump power (S75).
• Faulty turbomolecular pump (A) or turbomolecular pump controller (A).
• There is a fault in the System I/O Board.
1143* Error: Turbo pump not at desired speed.
The number of revolutions of the turbomolecular pump went below the limit (In
Analysis Mode).
Check the number of revolutions and the current of the turbomolecular pump,
vacuum pressure (AN), vacuum pressure (IF/BK), and S75 power voltage. The
following causes are inferred.
• A rise in the vacuum pressure.
• The connector of the turbomolecular pump came off.
• Fault of the power (S75) of the turbomolecular pump.
• Fault of the turbomolecular pump or the turbomolecular pump controller.
• There is a fault in the System I/O Board.
1144 Error: Turbo pump cooling fan malfunction.
The number of revolutions of the turbomolecular pump cooling fan went down
abnormally or stopped (In Analysis Mode).
1145 Error: Turbo pump (I) not at desired speed.
The number of revolutions of the turbomolecular pump (I) went below the limit
(When the instrument is changing from Analysis Mode to Standby Mode).
Check the number of revolutions and the current of the turbomolecular pump
(I), vacuum pressure (IF), vacuum pressure (BK), and S75 power voltage. The
following causes are inferred.
• A rise in the vacuum pressure.
• The connector of the turbomolecular pump (I) came off.
• Faulty turbomolecular pump power (S75).
• Faulty turbomolecular pump (I) or turbomolecular pump controller (I).
• There is a fault in the System I/O Board.
1146 Error: Turbo pump (A) not at desired speed.
The number of revolutions of the turbomolecular pump (A) went below the
limit (When the instrument is changing from Analysis Mode to Standby Mode).
Check the number of revolutions and the current of the turbomolecular pump
(A), vacuum pressure (AN), vacuum pressure (BK), and S75 power voltage. The
following causes are inferred.
• A rise in the vacuum pressure.
