Echo Profile
(cont.)
- Review an existing Echo
Rejection Profile
continued from previous page
4.) Enter Level- use this entry to manually enter the
correct level value
Error messages:
"Echo to Close" indicates the liquid is too close to the antenna.
Liquid should not be closer than 30" (750 mm).
"Echo to High" indicates an echo being rejected is too large.
a.) Ensure it is not the actual liquid level
b.) Rotate the Launcher to minimize the echo
5.) Saved Echo Rejection Profile-
a.) Enable or Disable an existing profile
b.) Review Echoes from an existing profile
c.) Review Level value where existing profile was run

Loop Control
(select)
Select mode for Loop Control
Select Level or Volume.
24
4 mA Set Point
(xxx.x units)
Enter the value for the 4 mA
point.
During normal operation, mA value will clamp at boundary
defined by the Level Offset value (refer to #17).
25
20 mA Set Point
(xxx.x units)
Enter the value for the 20 mA
point.
During normal operation, mA value will clamp at boundary
defined by the Blocking Distance value (refer to #16).
26
Damping
(xx sec)
Enter the Damping factor.
A damping factor (0-45) may be added to smooth a noisy
display and/or output due to turbulence.
27
System Fault
(select)
Select the System Fault value.
Select 3.6 mA, 22 mA or HOLD (last value).
28
Echo Loss Fault
(select)
Select the Echo Loss Fault
value.
Select 3.6 mA, 22 mA or HOLD (last value)
29
Echo Loss Delay
(xxx sec)
Enter the value for the Echo
Loss Delay.
Select a value 0-1000; 30 is default
30
Safe Zone Fault
(select)
Select the Safe Zone Fault.
Safe Zone is a user-defined area just below the Blocking
Distance. Set this Fault if it necessary to ensure safe, reliable
high-level readings in critical applications. Choices are 3.6 mA,
22 mA, Latch 3.6 or Latch 22. If Latch 3.6 or Latch 22 is chosen,
the loop current will remain in alarm until it it cleared by cus-
tomer in SZ Latch below (refer to #32)
31
Safe Zone Height
(xx.x units)
Enter a Safe Zone Distance.
Enter a distance value that develops a zone just below the
Blocking Distance. At this point the unit will report a Safety
Zone Fault (refer to #30) if the level rises into this area.
32
Safe Zone Alarm
(Reset)
Clear Safe Zone Alarm
Clear a latched Safe Zone alarm.
33
Trim Level
(xxx.x units)
Enter a Trim Level value
Trim Level is an offset value to be used to force the transmitter
to output the proper Level. This should only be used after Tank
Height and Sensor Offset have been confirmed as correct.
-24 to +24 inches (-61 to +61 cm)
34
Pipe I.D.
(xx.x units)
Enter Pipe I.D.
For measuring in a standpipe/stillwell. Enter a value for inside
diameter of the pipe. Range of values 0, 3-20 inches
(0, 40-500mm). Value must be left as 0 if no standpipe/stillwell
is present.
35
Trim 4 mA
Fine tune the 4mA point.
Attach a mA meter to the output. If the output does not equal
4.00 mA, adjust the value on the display until meter reads
4.00 mA. This is not for setting the 4mA point (refer to #24).
