5.0 Troubleshooting and Diagnostics
The PULSAR Model R96 transmitter is designed and engi-
neered for trouble-free operation over a wide range of oper-
ating conditions. The transmitter continuously runs a series
of internal self-tests and displays helpful messages on the
large graphic liquid crystal display (LCD) when attention is
required.
The combination of these internal tests and diagnostics
messages offer a valuable proactive method of troubleshoot-
ing. The device not only tells the user what is wrong, but
also, and more importantly, offers suggestions on how to
solve the problem.
All of this information can be obtained directly from the
transmitter on the LCD, remotely from the Fieldbus host
system, or by utilizing PACT
ware
and the PULSAR Model
R96 DTM.

PC Program
The PULSAR Model R96 offers the ability to perform
more advanced diagnostics such as Trending and Echo
Curve analysis using a PACT
ware
DTM. This is a powerful
troubleshooting tool that can aid in the resolution of any
diagnostic indicators that may appear.
5.1 Diagnostic Parameters
As mentioned above, the PULSAR Model R96 measure-
ment engine runs through a series of self-tests and will
detect and report faulty operation. The TRANSDUCER
BLOCK displays this diagnostic information in the STA-
TUS INDICATOR parameter. Refer to Section 5.1.3 for
more information on specific diagnostic indicators.
Note: Within the TRANSDUCER BLOCK,
BLOCK_ERROR is not used except for indicating Out of
Service (OOS).
For the first few seconds after power is applied to the Model
R96 transmitter, the LEVEL_STATUS/QUALITY is
“Uncertain,” the SUB_STATUS is “Initial value,” and the
LIMIT attribute is shown as “Constant.”
When the Model R96 is operating properly, the
LEVEL_STATUS/QUALITY is shown as “GOOD,” and
the SUB_STATUS is “Non-Specific.”
