WRITE TO UNIT
After you have entered configurations, selected and configured the Tank
Shape and entered the Tank Values, click “
Write to Unit
” and load the
configuration into the memory of the sensor. When completed, this
configuration will remain inside the sensor memory and will not change
unless the sensor is connected to the software and a new configuration
is written to the sensor. Loss of power will not change or lose the
configuration within sensor memory.
Next, use the file management features to save your configuration by
clicking “
Save Config File
” and print your wiring diagram by clicking
“
Wiring Diagram
.”

Save Config File
“
Save Config File
” will save this configuration as a text file which can be loaded back into LVCN414-SW by
pressing the “
Open Config File
” button. It is good practice to save the configuration file for each different
configuration with a unique name for easy identification. If using multiple sensors in identical applications, then
use of a single configuration file is recommended.
“
Wiring Diagram
” will display a PDF file showing the unique wiring for the specific configuration created in
LVCN414-SW. The PDF can be printed or emailed. It is good practice to save the wiring diagram as a
backup
.
“
Advanced
” is a feature setting designed to help solve performance or operational issues for specific
applications. Changing these setting will alter the factory default performance or operation, of your sensor.
Increase Output Filtering
: Placing a check mark in the box will increase the filtering (averaging) of the
analog output. Use this filter if the 4 to 20 mA output requires
a smoother output for the application such as open channel
flow measurement.
Decrease Output Filtering
: Placing a check mark in the box
will eliminate all filtering (averaging) of the analog output which
enables a pulse by pulse level reading. Use this filter to see
changes in level after every echo pulse.
Note:
Never check increase output filtering and decrease output
filtering at the same time.
Stabilize Output in Dead Band
: Placing a check mark in the
box will activate a filter to hold the output at Full if the level
enters the dead band of the LVU500 series. This filter requires the level to leave the dead band at a
smooth and steady rate.
Reduce Fast Level Jump Response Time:
Changes the sensor’s response time from 60 seconds to
10 seconds. This filter prevents the sensor from making a quick jump in level if a false signal suddenly
appears. Change the response time if application involves expected quick level changes.
Increase LOST Response Time:
Changes the sensor’s response time from 60 seconds to 180
seconds. This filter sets the time the sensor waits before entering a LOST state. Change the response
time if you want to delay the sensor from stating LOST.
