• Check for loose connection between boards
• Consult Factory
Loop Failure
The actual current generated in the 4-20 mA loop
differs significantly (> 1 mA) from the intended
loop current.
Consult Factory
SafeZoneAlrm
Level has risen to within SZ Height of Blocking
Distance point.
SZ Alarm notification choices:
i) 22 mA: loop driven to 22 mA while detected
level remains within SZ Height of Blocking
Distance point
ii) 3.6 mA: loop driven to 3.6 mA while detected
level remains within SZ Height of Deadband
iii) Latch 22 mA: loop held at 22 mA until
manually reset
iv) Latch 3.6 mA: loop held at 3.6 mA until
manually reset
v) None: safety zone not enabled. (default Safety
Zone Alarm state)
• Normal operation
• Change parameters to modify transmitter
actions
• Keep liquid from entering this area
Echo Lost
No valid echo from the liquid surface has been
received for a period exceeding the Echo Loss
Delay.
• Increase Turbulence setting
• Decrease Dielectric setting
• Increase Foam setting
• Increase ROC setting
• Increase LOE Delay
HiVolumeAlrm
The measured level exceeds the strapping table
SPAN by more than 5%.
• Increase the maximum Level/Volume capability
of the table
• Prevent liquid from reaching this level
HighFlowAlrm
The calculated flow exceeds maximum flow by
more than 5%.
Modify flow calculations or prevent liquid from
reaching this level.
