Fault 263—Host communications: GPIB (or HPIB)defective
Status message: GPIB (or HP-IB) defective
The communications between the GPIB (or HP-IB) chip and the mainboard
are faulty. Most likely, the mainboard is faulty. Communication between the
GC and the other device will halt.
Fault 264—Sampler communications: RS232 defective
Status message: Sampler RS232 defect
The communications between the RS232 chip and the mainboard are faulty.
Most likely, the mainboard is faulty. Communication between the GC and the
other device will halt.
Fault 265—Front inlet: invalid pids
Fault 266—Back inlet: invalid pids
Status message: F inlet invalid pid or B inlet invalid pid
pid is an abbreviation for the constants used in the algorithm that controls
temperature. This fault means that the module calibration is no longer valid.
Fault 267—Front detector: invalid pids
Fault 268—Back detector: invalid pids
Status message: F detector invalid pid or B detector invalid pid
pid is an abbreviation for the constants used in the algorithm that controls
temperature. This fault means that the module calibration is no longer valid.
Fault 269—Pneu aux module: invalid pids
Status message: Pneu aux invalid pid
pid is an abbreviation for the constants used in the algorithm that controls
temperature. This fault means that the module calibration is no longer valid.
