Comment
Safety Zone Flt
Safety Zone Alarm has been tripped.
Decrease level in vessel.
No Signal
No level signal being detected.
1) Ensure Dielectric setting is correct for the measured medium.
2) Increase Sensitivity
3) Confirm Probe Model is proper for the dielectric of the medium.
4) Consult factory.
EOP<Probe Length
End of Probe signal from a dry probe
is out of range.
1) Ensure the Probe Length is entered correctly.
2) Set Dielectric to a lower dielectric range.
3) Consult factory.
4) Ensure proper Blocking Distance.
Lvl<Probe Length
Apparent position of the upper level
pulse is beyond the end of the probe.
1) Check entered Probe Length.
2) Change Threshold to Fixed.
EOP High
End of Probe signal is out of range.
1) Ensure Probe Length is entered correctly.
2) Consult factory.
High Volume Flt
Level more than 5% above highest point
in strapping table.
1) Verify strapping table is entered correctly.
2) Signal amplitude may be lower than desired.
Hi Temperature
Present temperature in electronics
compartment is above 80 C.
1) Transmitter may need to be moved to ensure ambient
temperature is within specification.
2) Change to remote mount transmitter.
Lo Temperature
Present temperature in electronics
compartment is below -40° F (-40° C).
1) Transmitter may need to be moved to ensure ambient
temperature is within specification.
2) Change to remote transmitter.
Default Cal
Factory set default calibration
parameters are in use. Level reading
may be inaccurate.
Consult factory.
No Steam Target
No steam target detected on
Model 7x5 probe.
Consult factory.
Initializing
None
Program is initializing. This is a transient condition.
May be Flooded
Loss of level signal possibly due to
flooding. Twin Rod probes only.
1) Decrease level in vessel.
2) Set Dielectric to lower range value.
3) Replace with Model 7xR Overfill probe.
Dry Probe
None
Normal message for a dry probe. End of Probe signal is being
detected in correct location.
Weak Signal
None. Signal amplitude is lower than
desired.
1) Set Dielectric to a lower range value.
2) Increase Sensitivity.
