Model MCB10A 6-3
6-2 : Troubleshooting
6-2-1 : Types of troubles
Introduction
The troubles that can occur when booting and starting up the instrument include the
following three types:
• Troubles caused by inconsistencies between the specifications and actual service
conditions of the instrument
• Troubles caused by mistakes in settings or operations
• Troubles caused by failures of the instrument
The troubles that can occur while running the instrument are divided into critical
failures and non-critical failures as described below, and they are recognized,
indicated or treated as such by the self-diagnosis function of the instrument.
If a trouble should occur, take the appropriate measure referring to the
troubleshooting guide given here.
Critical failure
A critical failure is defined as a state or failure that causes a grave hindrance to the
operation of the instrument and may lead to damage to the instrument itself if left
untreated. If a grave trouble occurs while the instrument is running, an error message
is displayed on the display panel of the main unit and the output continues to deliver
the value that was set in the direction of abnormality processing
Non-critical failure
A non-critical failure is defined as a state or failure that does not cause a grave
hindrance to the operation of the instrument. If some trouble occurs while the
instrument is running but the instrument judges it by self-diagnosis as a minor
trouble, the output does not switch to the abnormality processing output and the
instrument continues to deliver the instantaneous flow rate value.
