Important Notice to the User
This manual contains information for servicing YOKOGAWA’s MX100/MW100 Data
Acquisition Unit. Check the serial number to confirm that this is the correct service
manual for the instrument to be serviced. Do not use the wrong manual.
Before any maintenance and servicing, read all safety precautions carefully.
Only properly trained personnel may carry out the maintenance and servicing
described in this service manual.
Do not disassemble the instrument or its parts, unless otherwise clearly permitted by
this service manual.
Do not replace any part or assembly, unless otherwise clearly permitted by this
service manual.
In principle, Yokogawa Electric Corporation (YOKOGAWA) does not supply parts other
than those listed in the customer maintenance parts list in this service manual (mainly
modules and assemblies). Therefore if an assembly fails, the user should replace the
whole assembly and not components within the assembly (see “Note”). If the user
attempts to repair the instrument by replacing individual components within the assembly,
YOKOGAWA assumes no responsibility for any consequences such as defects in
instrument accuracy, functionality, reliability, or user safety hazards.
YOKOGAWA does not offer more detailed maintenance and service information than that
contained in this service manual.
All reasonable efforts have been made to assure the accuracy of the content of this
service manual. However, there may still be errors such as clerical errors or omissions.
YOKOGAWA assumes no responsibility of any kind concerning the accuracy or contents
of this service manual, nor for the consequences of any errors.
All rights reserved. No part of this service manual may be reproduced in any form or by
any means without the express written prior permission of YOKOGAWA. The contents of
this manual are subject to change without notice.
Note
YOKOGAWA instruments have been designed in a way that the replacement of electronic parts
can be done on an assembly (module) basis by the user. YOKOGAWA instruments have also
been designed in a way that troubleshooting and replacement of any faulty assembly can be
done easily and quickly. Therefore, YOKOGAWA strongly recommends replacing the entire
assembly over replacing parts or components within the assembly. The reasons are as follows:
• Repair of components can only be performed by specially trained and qualified maintenance
personnel with special tools. In addition, repair of components requires various special parts
and components, including costly ones. It also requires facilities where highly-accurate and
expensive maintenance equipment and special tools are provided.
• When taking the service life and cost of the instruments into consideration, the replacement
of assemblies offers the user the possibility to use YOKOGAWA instruments more effectively
and economically with a minimum in downtime.
