Description Corrective action
53 Transmission Lost The transmission is too low to
continue measurements.
Check that the alignment is correct. Check
whether the laser beam is being blocked.
Check whether the process window is
stained. For details, see “9.1
Maintaining the Laser Beam and
Transmission”.
54 Ref Trans Low The reference cell transmission is
too low.
Contact your Yokogawa service
representative.

10.2 Warning Display and Handling
A warning occurs when the various types of diagnostic information being monitored by the
TDLS8000 self-diagnostics function are outside the normal range. If a warning occurs, the
TDLS8000 output and display will respond in the following manner.
• The analog output is set to the specified state (the factory default hold setting is off).
• DO digital output is generated (for the digital output wiring, see “3.2.5 Wiring Digital
Outputs”).
• The DO LED (yellow) lights.
• The alarm indicator blinks on the YH8000 display.
• Alarm information is indicated over HART communication (see section 7.4).
• Alarm information is shown on the SCU display.
The following table shows the warning types and their corrective actions. Alarm numbers
are defined for warning type identification. These numbers are shared among the YH8000,
HART, and SCU displays, even though the abbreviations of the displayed warning names may
differ. Depending on the alarm, a sub number may also be displayed. This number is used by
Yokogawa service representatives for troubleshooting purposes.
