6.0 Diagnostic Parameters
The E3 MODULEVEL measurement engine runs through
a series of self-tests and will detect and report faulty opera-
tion. The MODULEVEL TRANSDUCER BLOCK
displays these faults in the DEVICE_STATUS parameter.
Refer to Section 8.3.3 for more information on specific
faults and warnings.
BLOCK_ERROR is not used except for indicating Out of
Service (OOS).
When the Model E3 transmitter is initially powered on, the
measurement engine does not have enough valid measure-
ment cycles to make a decision about the output level. For
the first twenty-two measurement cycles after power is
applied, the QUALITY is “Uncertain,” the SUB_STATUS
is “Initial value,” and the LIMIT attribute is “Constant.”
When the Model E3 is operating correctly, the QUALITY
is shown as “GOOD,” and the SUB_STATUS is “Non-
Specific.”
While changing the transmitter operational parameters
using the local display or through the system configuration
tool (with the MODE_BLK in OOS), the output might be
inaccurate because of the changing parameters. When the
device is in a mode where operational parameters can be
changed, the MODULEVEL TRANSDUCER BLOCK
will still output level but the QUALITY will be shown as
“Bad” and the SUB_STATUS is “Out of Service.”
