Things to check
Check the Product Volume
Range
Check Distance to Product,
Product Level and Distance to
Interface, Interface Level (if
Two Liquid selected) values
are valid
Verify parameter:
Product Volume Value
Status is not GOOD
Check Sensor Configuration
Check Distance to Product,
Product Level value.
Check Distance to Product,
Product Level value.
Check Distance to Interface
and Interface Level value and
Measured Product is selected
as Two Liquid (Non Flooded)
Check the Electronic Housing
temperature units.
Read FEATURE_SEL.
Read LIM_NOTIFY.

Recommended action
Ensure that Product Volume
Range has valid ranges and units
assigned.
Verify that sensor and correlation
algorithm configuration.
Verify that correct Volume
Calculation type is selected and
correct tank configuration is
assigned in the Auxiliary
Transducer Block.
Ensure Auxiliary Transducer Block
is in AUTO mode.
Verify that correct Measured Type,
Dielectric constant, Sensor height,
Maximum Product Height, Probe
Type, Probe Length and Blocking
Distance High and Low values are
assigned.
Verify that correct Correlation
Algorithm Surface and Interface
values are assigned by reading
Echo curve again.
Verify sensor configuration and
correlation algorithm configuration
Verify sensor configuration and
correlation algorithm configuration
Ensure that proper unit is
assigned to Electronic Housing
temperature.
Reports are not selected in
FEATURE_SEL. If features do not
include Reports then the host
must poll for alarms.
Set LIM_NOTIFY to a value higher
than zero, but not higher than
MAX_NOTIFY.
