Problem
Software believes probe is
flooded (level very near top of
probe)
Possible configuration issue
with single rod probe
Possible obstruction in tank
affecting single rod probe
Transmitter loose or discon-
nected from probe
Action
None
None
None
End of Probe signal from a
dry probe is out of range
End of Probe signal is out of
range
Highest level signal
detected is below Probe
Length
End of Probe signal is
below Probe Length
None. Signal amplitude is
lower than desired
Corrective Action
Check actual level. If probe is
not flooded, check for buildup
or obstructions near top of
probe. Select higher dielectric
range. Check for condensation
in probe connection. Add
Blocking Distance.
1. Increase Blocking Distance.
2. Increase Dielectric Range.
1. Increase Dielectric Range
until obstruction is ignored.
2. Relocate probe away from
obstruction.
Ensure transmitter connected
securely to probe.
Comment
Normal Operating Mode
Program is initializing, level reading
held at 4 mA setpoint. This is a tran-
sient condition
Normal message for dry probe. End of
probe signal is being detected.
• Ensure probe length is entered
correctly.
• Set transmitter to a lower dielectric
range.
• Ensure probe length is entered
correctly.
• Consult factory.
• Ensure probe length is entered
correctly.
• Ensure probe length is entered
correctly.
• Set transmitter to lower dielectric
range
• Increase sensitivity
