Step Three About this Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This manual includes information on the LVCN‐40 Series level indicator from OMEGA ENGINEERING. Please refer to the part number located on the switch label to verify the exact model configuration, which you have purchased. User’s Responsibility for Safety: OMEGA ENGINEERING manufactures a broad range of level sensing technologies. While each of these sensors is designed to operate in a wide variety of applications, it is the user’s responsibility to select a sensor model that is appropriate for the application, install it properly, perform tests of the installed system, and maintain all components. The failure to do so could result in property damage or serious injury. ... -

LVCN‐414, LVCN‐210 & LVCN‐318 Series sensor and display the level per the sensor’s configuration. The sensor does require configuration with the LVCN‐414‐SW 6.0 software (especially if any relays are to be used). For a copy of the LVCN‐414‐SW 6.0 software, please go to http://www.Omega.com/ftp, click on the Flow, Level, pH, Environmental, and Pressure Section, select Products and then click on the LVCN414 folder. Before attaching LVCN‐40 Series to any sensor, configure the LVCN‐414, LVCN‐210 & LVCN‐318 Series sensor to LVCN‐414‐SW 6.0 software via the Fob. Once the sensor is ... -
Page 7: Wiring
WIRING Step Five Wiring LVCN‐40 Series to any LVCN‐414, LVCN‐210 & LVCN‐318 Series Sensor: LVCN‐40 Series and associated level sensor require a 12 to 28 VDC power supply to operate. The maximum cable distance between LVCN‐40 Series and the sensor is 15’ (4.5m). Follow the below steps to wire LVCN‐40 series with the sensor: LVCN‐40 Series Sensor Wiring identical for all series of LVCN‐414, LVCN‐210 & LVCN‐318 Series Sensors. Use only the Red, Black, Green and White wires. 1. Connect the Red and Black wires of both LVCN‐40 Series and the sensor to the 12‐28 VDC power supply. 2. Connect the Green and White wires of LVCN‐40 Series to the corresponding Green and White wires of the sensor. 3. Isolate the Green and White wires from active power to prevent a short of the configuration circuit. Adding a Loop Powered Display General Safety Where personal safety or significant property damage can occur due to a spill, the application must have a redundant backup safety system installed. Wiring should always be done by a licensed electrician. Supply voltage should never exceed 28 VDC. Protect the sensor from electrical spikes by isolating the power. Design a fail‐safe system for possible indicator and/or power failure. Never use the sensor in environments classified as Hazardous. 7 ... - Page 8 UNDERSTANDING LVCN‐40 SERIES Step Six Level Height vs. Volume: The latest version of LVCN‐414‐SW 6.0 software has a new feature which allows the sensor to be configured to read either the height of the liquid or the volume of the liquid. This selection is made under the Sensor Output Units selection of either Volume (volume of liquid) or Distance (height of liquid). See the chart below for the engineering unit options available for both Distance and Volume. Units of Measurement Distance Volume Inches Gallons Cm Liters Feet Meters There are 6 different tank shapes that you can select with LVCN‐414‐SW 6.0 Software. Rectangular Tank Vertical Cylinder Tank Vertical Cylinder Tank with Cone Bottom ...

Page 9: Linear Vs. Non-Linear
UNDERSTANDING LVCN‐40 SERIES Step Six Linear vs. Non‐Linear: Two of the shapes (Vertical Cylinder Tank and Rectangular Tank) will always provide a linear output, regardless of selecting Distance or Volume. The remaining four shapes (Vertical Cylinder Tank with Cone Bottom, Horizontal Cylinder Tank with End Caps, Horizontal Cylinder Tank with Spherical End Caps and Spherical Tank) will have a linear output when Distance is selected, but will have a non‐linear output when volume is selected. Vertical Cylindrical Tank Horizontal Cylinder Tank with End Caps In the above illustration, 10” of liquid will always In the above illustration, 10” of liquid does not be equal to 100 gallons of liquid (1” = 10 gallons). equal 100 gallons. The 10” at the bottom represents a rise of 62.8 gallons where the change ... -

UNDERSTANDING LVCN‐40 SERIES Step Six Example #2 (Current Output): in the illustrations below, the 4mA signal is set at 0” (0.0 gallons) and the 20 mA signal is set to 60” (600.0 gallons). In the Vertical Cylindrical Tank, 40” of liquid will output a current signal of 14.67mA. However, in the Horizontal Cylindrical Tank with End Caps, 40” of liquid will output a current signal of 15.41mA. A simple loop display set with 4mA = 0 gallons and 20 mA = 600 gallons will show two different volumes based upon the tank shape configuration. Vertical Cylindrical Tank will show 400.0 gallons ... -

Page 12: Installation
INSTALLATION Step Seven LVCN‐40 Series is designed for typical panel mount installations, either located within an instrument panel or through the wall of a NEMA box enclosure. Panel Mount: The maximum cable distance between LVCN‐40 Series and LVCN‐414, LVCN‐210 & LVCN‐318 Series sensor is 15’ (4.5m). Follow the below steps to install the indicator in a panel or NEMA box enclosure located near the sensor: 1. Drill (1) large 0.75” (19.1mm) diameter hole in the panel for the cable and nipple. 2. Drill (1) small 0.25” (6.4mm) diameter hole 0.83” (21.1mm) below the large hole that will prevent the installed indicator from rotating off center. ... - Page 13 GETTING AROUND LVCN‐40 SERIES Step Eight LVCN‐40 Series features a 6‐digit display with relay indicators and a three‐button user interface.

GETTING AROUND LVCN‐40 SERIES Step Eight Changing a Pump Set Point: Sensors (LVCN‐414, LVCN‐210 & LVCN‐318 Series) with relays have (1‐4) channels active on the LVCN‐40 Series. If after accessing the MENU, PUMP appears in the display, then at least (1) relay is configured for pump or valve control. Simplex pump control has (1) ON and (1) OFF setting. Duplex pump control (2‐pumps) has a third additional LAG setting. Note: Prior to making any changes, we recommend that you write down all existing set point values. The example below highlights a duplex pump system in an automatic empty or automatic fill operation with (1) LAG, (1) ON and (1) OFF set point. Use the following steps to change your simplex or duplex pump control settings. ... -
Page 15: Changing An Alarm Set Point
GETTING AROUND LVCN‐40 SERIES Step Eight Changing an Alarm Set Point: Sensors (LVCN‐414, LVCN‐210 & LVCN‐318 Series) with relays have (1‐4) channels active on the LVCN‐40 Series. If after accessing the MENU, ALARMS appears in the display, then at least (1) relay is configured as an alarm. The Alarm settings may be in any combination of LOW and/or HIGH alarms (4‐HIGH, 1‐LOW & 3‐HIGH, 2‐LOW & 2‐HIGH, etc.). Note: Prior to making any changes, we recommend that you write down all existing set point values. The example below highlights a 2‐LOW and 2‐HIGH alarm operation with (4) set points. Use the following steps to change your alarm settings. Steps to change Alarm settings: 1. Hold SELECT for 5 seconds to enter the MENU. 2. Press SELECT when ALARMS appears. 3. Press SELECT when the set point (HIGH2, HIGH 1, LOW1, LOW2) you want to change appears. 4. Press the UP and DOWN buttons to increase or decrease the set point to the desired value. To scroll faster, hold SELECT while pressing UP or DOWN. ... -
Page 16: Troubleshooting
TROUBLESHOOTING Step Nine Display Descriptors: The following are the display’s operational descriptors, meaning and corrective action: WARMUP is seen when power is first applied to the sensor and LVCN‐40 Series. WARMUP WARMUP indicates that the display is waiting for the sensor to acquire and send a valid level reading. MENU Indicates the menu for configuration of relay set points. PUMP PUMP is the identifier for the relay set points affecting Pump or Valve operations. OFF is the relay set point that turns OFF the pump. ON is the relay set point that turns ON the pump. LAG is the set point that turns ON the lag pump. ALARM Alarm is the identifier for the relay set points affecting Alarm operations. HIGH # HIGH # is the relay set point that energizes a high alarm relay. LOW # LOW # is the relay set point that energizes a low alarm relay. Not All four wires are properly connected to the sensor. Check the wiring between the CHECK WIRES LVCN‐40 Series and the level sensor. The attached sensor is not running a version of the firmware (50.0 or higher) that is UPDATE FW REV compatible with LVCN‐40 Series. Connect the LVCN‐414, LVCN‐210 or LVCN‐318 Series to the LVCN‐414‐SW 6.0 software and update the firmware. 16 ... - Page 17 17 ...
