MODEL 1000
5.1
TROUBLESHOOTING AND REPAIR CONCEPT
The most efficient method for maintaining (repairing) the Model 1000 GC System is based on a
unit-replacement concept that permits returning the system to operation as quickly as possible.
Sources of trouble, such as printed-circuit assemblies, valves, etc., are identified during
troubleshooting test procedures and are replaced at the lowest level practical with units in known
working order. The defective elements are then either repaired in the field by reference to the
applicable instructions or returned to Emerson Process Management for repair or replacement.
5.2
ROUTINE MAINTENANCE
The Model 1000 GC System will perform accurately for long periods with very little attention.
However a bi-monthly record of certain parameters will assist greatly in assuring that your Analyzer
is operating to specifications. The GC System Maintenance Checklist should be filled in bi-monthly,
dated, and kept on file for access by maintenance technicians as necessary. See next page. This
gives you a historical record of the operation of your Analyzer, enables a maintenance technician to
schedule replacement of gas cylinders at a convenient time, and allows quick troubleshooting and
repair when it becomes necessary. A chromatogram, a configuration report, and a raw data report
should also be made and filed with the checklist, furnishing a positive dated record of the Analyzer.
The chromatogram and reports will also prove valuable in comparison with the chromatograms and
reports run during troubleshooting.
Copy the GC System Maintenance Checklist (next page) as necessary for your files. If you have a
problem, please complete the checklist and reports, and have the results available when calling
Daniel Measurement Services (DMS), a division of Emerson Process Management, with a problem.
Also have the Sales Order number when calling. The Sales Order number can be found on the upper
right hand corner of the upper electronics housing of the Analyzer. The chromatograms and reports
archived when your Analyzer left the factory are filed by this number (i.e. "HE-xxxxx") or (xxxxx).
Two numbers may be found. Record both numbers. One is the sales order number and the other is
the serial number.
