Warnings Table 6-3 is a list of diagnostic messages that may be displayed on the
Integral Display, on the Model 375 Field Communicator or by the Radar
Configuration Tools (RCT) software. Warnings are less serious than errors
and in most cases do not result in Analog Output alarms.
Warnings are indicated by a message at the bottom of the RCT workspace. To
see the warning message do one of the following:
• Click the Read Gauge Status icon in the toolbar at the top of the
RCT workspace.
• 1. Open the Advanced section in the RCT workspace Project Bar and
click the Device Commands icon,
or
choose the Device Commands option from the View menu.
2. Open the folder named Diag and double-click the Read Gauge
Status option.
Table 6-3. Warning messages.
Message Description Action
Reference pulse not
found. Possible cause:
• Reference pulse immersed in
high dielectric liquid.
• Wrong threshold level T1.
• Hardware error.
• View the waveform plot and check
amplitude threshold T1.
• Check that the tank is not overfull.
No level pulse is
found. Possible cause:
• Wrong threshold level T2.
• Liquid level in Dead Zone or
below probe end.
• View the waveform plot and
check amplitude threshold T2.
Interface pulse not
found. Possible cause:
• Wrong threshold level T3.
• Interface level too close to the
upper product level.
• No level pulse detected.
• View the waveform plot and
check amplitude threshold T3.
Internal temperature
out of range. -40 ºC<Internal Temperature<85 ºC. Contact Rosemount service
department.
Volume computation
warning. • Volume configuration error.
• Strapping table error. • Check that correct tank type is
selected for volume configuration.
• Check that tank dimensions for
volume are correct.
• If strapping table is used, check the
level vs. volume points.
Immersed probe. • Wrong threshold level T4.
• Reference pulse immersed in
liquid.
• View the waveform plot and check
amplitude threshold T4.
