Page 3: Safety Precautions
SAFETY PRECAUTIONS Step Two About this Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This manual includes information on the LVU-90 series continuous non-contact level transmitter from OMEGA. Please refer to the part number located on the sensor label to verify the exact model which you have purchased. -
Page 4: Installation
WIRING Step Four Follow the instructions in Step 3 for wiring to the LVU-90. 1. Wiring to an OMEGA Continuous Controller (LVCN-51): Connect the (+) terminal to the positive 24 VDC, 25 mA terminal on the controller. Connect the (-) terminal to the GND terminal on the continuous controller (See illustration below). - Page 5 CALIBRATION Step Six The LVCN-90 is factory calibrated with a fixed measurement span of 6 feet. The 4 mA position is located 72" from the transducer face. The 20 mA position is located 3.6 inches from the transducer face. Refer to the current to distance and distance to current conversion charts in step seven for reading the current output.

Page 6: Maintenance
MAINTENANCE Step Eight General: The LVCN-90 series level transmitter itself requires no periodic maintenance except cleaning as required. It is the responsibility of the user to determine the appropriate maintenance schedule, based on the specific characteristics of the application liquids. Cleaning Procedure: 1.
