The next set of conditions is the device warnings. The con-
dition will not jeopardize the level measurement. However,
knowledge of the condition may be useful in troubleshooting
the device.
The following table describes the conditions that can be
seen in Device Status:
OK None Normal operating mode.
User Access Password at the local display. Parameter values are being changed through the local interface.
Make sure
Transducer Block is taken out of serv
ice.
Factory Access Password at the local display. Parameter values are being changed through the local interface.
Make sure
Transducer Block is taken out of serv
ice.
Default Params Internal non-volatile parameters have
been defaulted.
Consult factory.
No End of Ramp No End-of Ramp signal detected. Consult factory.
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.
No Fiducial Fiducial signal is not being
detected.
1) Check connection between probe and transmitter.
2) Check for moisture on top of probe.
3) Check for damaged gold pin in the high frequency connector.
4) Consult factory.
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.
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 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.
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.
