5-8 Agilent 7500 Series ICP-MS Hardware Manual
5 Troubleshooting
The following causes are inferred.
• Either the large cover or the small cover is opened, or S24V is not supplied
for other reason---check the voltage of the S24V.
• The lenses or the lens and the chamber are touching each other.
• There is a fault in the HV driver board.
1021 Execution Error: Turbos slow speed must be done in Standby mode
and Vacuum pressure (AN) is low.
As the vacuum pressure (AN) exceeds the limit, the turbomolecular pump
cannot be changed to the operation mode (slow speed) (In Standby Mode).
• Check the pressure of the analyzer chamber. The following causes are
inferred.
• The vent valve is not closed or the seal is incomplete.
• The cover of the vacuum chamber is not closed or the seal is incomplete.
• The power of the rotary pump is not connected or the breaker is OFF.
• The rotary pump oil level is low or the oil is dirty.
• There is a leak in the gate valve.
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an
incomplete seal such as a pin hole or a defective O- ring).
• There is a fault in the Penning gauge or the System I/O Board
1022 Execution Error: Can not open bypass valve because of high cell
pressure.
The bypass valve cannot work because the reaction cell pressure is too high.
The following causes are inferred.
• Reaction gas is supplied.
1023 Execution Error: Reaction mode can be turned on and off only in
Analysis mode.
Attempted to execute a command only available in Analysis mode. It is not in
Analysis mode now.
1024 Execution Error: Reaction mode can not be turned on/off during
transitional period of Reaction- Standard transition.
Reaction mode can not be turned on/off during Reaction- Standard transition.
The mode is under transition now.
1025 Execution Error: Reaction gas can be flowed only in Analysis mode.
Reaction gas can flow only in Analysis mode. It is not in Analysis mode now.
