Display Message

Action

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.
