Important Information!
This Operator´s Manual contains important warnings and safety information to be observed by the
user.
This instrument is only intended for one area of application which is described in the instructions. The most important prerequisites for application, operation and safety, are explained to
ensure smooth operation. No warranty or liability claims will be covered if the instrument is
applied in areas other than those described or if the necessary prerequisites and safety
measures are not observed.
The instrument is only to be operated by qualified personnel capable of observing these
prerequisites.
Only accessories and supplies either delivered by or approved by AVL are to be used with the
instrument.
Due to the operating principle of the instrument, analytical accuracy not only depends on
correct operation and function, but also upon a variety of external influences beyond the
manufacturers control. Therefore, the test results from this instrument must be carefully
examined by an expert, before further measures are taken based on the analytical results.
Instrument adjustment and maintenance with removed covers and connected power mains are
only to be performed by a qualified technician who is aware of the dangers involved.
Instrument repairs are only to be performed by the manufacturer or qualified service personnel.
Symbol Explanation
Attention symbol - Refer to the Operator's Manual or Service
Manual for further instructions. This symbol is located on the
inside of the instrument.
Type B instrument symbol - An instrument of the B type falls under
safety categories I, II, or III, or has an internal power supply providing
the required insulation against discharge current and reliable ground
connections.
Important Information!

Operating Safety Information
• This instrument falls under Safety Category I.
• This instrument is a Class B instrument.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference’s, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communication. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does not cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio TV technician for help
Caution:
• The instrument is designed as a conventional device (closed, not waterproof type).
• Do not operate the instrument in an explosive environment or in the vicinity of
explosive anesthetic mixtures containing oxygen or nitrous oxide.
• This instrument is suitable for continuous operation.
• The power plug is to be plugged into a ground socket only. When using an extension
cord, make sure that it is of the proper size and is properly grounded.
• Any breakage of the ground lead inside or outside the instrument or a loose ground
connection can cause a hazardous condition when operating the instrument.
Intentional disconnection of the grounding is not permitted.
• When replacing the fuses, make sure that they are of the same type and rating as the
original fuses. Never use repaired fuses or short-circuit the fuse holders.

1 Introduction
The Service Manual for the 9120, 30, 40, 80, and 81 Electrolyte Analyzers
contains the technical information needed to ensure easy fault identification.
This manual is intended to be complementary to the Operator's Manual where
detailed instructions for operation, maintenance and troubleshooting are
provided.
As for all clinical instrumentation, a thorough understanding of the principles
of operation is prerequisite to attempting service of this product. Training
along with experience will enhance the use of this manual.
Service and repair of 9120, 30, 40, 80, and 81 analyzers should be performed
only by qualified repair technicians. Care should be taken when removing the
covers as hazardous voltages are exposed. Use only accepted electronic test
procedures and static protection when replacing and handling all electronic
parts.
This manual is divided into 9 chapters to facilitate location of technical information. Chapter 2 provides specifications and operating parameter information. Chapter 3 includes flow charts for all system functions and detailed
operation of system test procedures. In Chapter 4, all mechanical, fluidic and
electronic assemblies are described. Chapter 5 outlines routine maintenance
and troubleshooting procedures. Chapter 6 includes electronic adjustments
and Chapter 7 provides the system block diagram and all circuit schematic
diagrams and wiring interconnection information. In Chapter 8, part identification, location and description is provided by the illustrated parts list.
Finally, in Chapter 9 interface specifications are provided for the RS232
output.
