About this Manual:

PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This manual includes information on the EchoSpan series Ultrasonic Level Switch from FLOWLINE. 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:

FLOWLINE 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.

Proper Installation and Handling:

Only professional staff should install and/or repair this product. Install the switch with the included Viton gasket and never over tighten the switch within the fitting. Always check for leaks prior to system start-up.

Wiring and Electrical:

A supply voltage of 12 to 28 VDC is used to power the EchoSpan. Electrical wiring of the transmitter should be performed in accordance with all applicable national, state, and local codes.

Material Compatibility:

The enclosure is made of Polycarbonate (PC). The transducer is made of Polyvinylidene Fluoride (PVDF).

Make sure that the model, which you have selected, is chemically compatible with the application media.

Enclosure:

While the switch housing is liquid-resistant the EchoSpan is not designed to be operational when immersed. It should be mounted in such a way that the enclosure and transducer do not come into contact with the application media under normal operational conditions.

The enclosure has a flip cover with dual 1/2” NPT female conduit ports and an internal terminal strip for wiring.

To open the enclosure, you will need a small insertion tool such as a screwdriver. Loosen the locking screw located at the top front of the enclosure. Rotate the hinged cover up for 135° access to the faceplate and terminal strips. Before closing the enclosure, make sure that the enclosure gasket is properly seated, and that any conduit fittings, cable connectors or plugs are installed correctly and sealed.

Handling Static-Sensitive Circuits/Devices:

When handling the transmitter, the technician should follow these guidelines to reduce any possible electrostatic charge build-up on the technician’s body and the electronic part.

1. Always touch a known good ground source before handling the part. This should be repeated while handling the part and more frequently after sitting down from a standing position, sliding across the seat or walking a distance.

2. Avoid touching electrical terminals of the part unless making connections.

3. DO NOT open the unit cover until it is time to calibrate.

General notes for electrical connections, usage and safety:

Where personal safety or significant property damage can occur due to a spill, the installation must have a redundant backup safety system installed.

Wiring should always be completed by a licensed electrician.

Supply voltage should never exceed 28 VDC.

The sensor materials must be Chemically compatible with the liquids to be measured.

Design a fail-safe system for possible sensor and/or power failure.

Never use the sensor in environments classified as Hazardous.

Voltage Output

EchoSpan can be used as a 0 to 5 or 0 to 10 VDC output device. A resistor will need to be added to the circuit to enable a voltage output (refer to the wiring diagram below).

0-5 VDC output o Add a 250 Ohm resistor o Actual output will be 0.8 to 5 VDC

0-10 VDC output o Add a 500 Ohm resistor o Actual output will be 2 to 10 VDC

Getting Started:

EchoSpan can be configured before installation. The switch features non-volatile memory, so the set points configured before installation will not be lost when the switch is powered down. To start, all you need is the following information:

Basic Tank Information: o HEIGHT – Distance from the transducer face to the bottom of the tank. o FILL-H – Maximum fill height of the liquid from the bottom of the tank. o These values will all be in the same distance value (inches, centimeters, feet or meters) and will all be measured from the bottom of the tank.

Power: o Provide 12 to 28 VDC input power to the

EchoSpan.

Installation

The EchoSpan should always be mounted perpendicular to the liquid surface and installed using the provided Viton mounting gasket. Make sure that the fitting and transmitter threads are not damaged or worn. Always hand-tighten the transmitter within the fitting. Perform an installed leak test under normal process conditions prior to system start up. Note: The preferred mounting fitting for the LU80

series is the LM52-1400 (2” thread x 1” thread) reducer bushing.

Mounting Guide

1. Do not mount at an angle

2. Liquid should never enter the dead band

3. Side Wall: a. For LU80 Series - mount at least 2” from the side wall b. For LU81, LU83 & LU84 Series - mount at least 3” from the side wall

4. Do not mount where obstacles will intrude on sensor’s beam width a. See Specifications on page 8

5. Do not mount in a vacuum

6. Avoid mounting in the center of a dome top tank.

7. In cone bottom tank, position the sensor over the deepest part of the tank.

Do not install at angle relative to the liquid.

Do not install within

3” of tank sidewall.

Do not install with objects in the beam.

Do not install in applications with vacuum.

Installation in existing fittings

If the existing fitting is larger than the threads of the EchoSpan, select a reducer bushing such as the

LM52-1400 (2” thread x 1” thread) or LM52-2400 (3” thread x 2” thread).

Metal Tanks (LU80 series)

Flowline ultrasonic transmitters have been optimized for use in non-metallic fittings.

1. For best performance, avoid the use of metallic fittings. a. Use a plastic 2” x 1” reducer bushing, such as the LM52-1400 or a plastic 1” flange, such as the LM52-1850 for metallic tanks.

2. While installations directly into a 1” metal fitting are not recommended, acceptable results may be obtained if the 1” fitting is a half coupling in form and the outer diameter of the coupling is tightly wrapped in vinyl tape to dampen vibrations.

3. Flange (LU80 series): If installing on a flange, select a flange with a thread that is above the plane of the flange, such as the LM52-1850.

a. The LU81, LU81 & LU83 series works well with Flange installations.

b. Avoid the use of blind flanges with tapped threads or flanges where the threads are even with the plane of the flange, such as the Banjo 1" Poly ANSI Flange (series

AF100). c. Use a flange with a 2” thread and add a 2” to 1” reducer bushing to complete the installation.

2” Flange w/ thread out of plane

2” Flange w/ thread in plane

2” Flange w/

Reducer Bushing

Do not use thread in plane

4. Side Mount Bracket: For installations in open tanks and sumps, use the LM50 series side mount bracket. a. For the LU80 series, order the LM50-1001-1, which includes a 2”x 1” Reducer

Bushing. b. For the LU81, LU83 & LU84, series, order the LM50-1001 side mount bracket.

5. Stand Pipe: A standpipe maybe used to dampen turbulence or when foam is present in the application. a. Pipe can be made of any material. b. Select a minimum 3” ID pipe for the stand pipe. i. A 2” pipe is usable with the LU80 series, but is the minimum. ii. Pipes larger than 3” can also be used. c. Use a coupling and reducer bushing to attach the EchoSpan to the pipe. i. With the LU80 series, be sure to use a plastic reducing bushing such as LM52-

1400 2” T x 1” T fitting or the LM52-1410 2” S x 1” T fitting. d. The pipe length should run the measurement span and the bottom of the pipe should remain submerged at all times to prevent foam from entering the pipe. e. Cut a 45°notch at the bottom of the pipe and drill a 1/4”pressure equalization hole in the dead band. f. The pumps should not drive liquid past the open end of the stand pipe which causes the liquid in the pipe to oscillate.

Troubleshooting:

PROBLEM SOLUTION

TANK does not appear on the main menu:

Transmitter indicates a current over 23 mA:

Units function is set for PERCENT on EchoSpan: When Units is set for PERCENT, the TANK function is disabled. To re-enable

TANK, change units to INCHES, CM, FEET or METERS.

Display shows FULL: Level of liquid is above the FILL-H setting: Check the FILL-H setting, making sure the FILL-H setting is high enough so the level of liquid is below the FILL-H setting. The Fill-H setting is the distance from the bottom of the tank to the Full level of liquid.

Display shows EMPTY: Level of liquid is beyond the HEIGHT setting: Check the

HEIGHT setting, making sure the HEIGHT setting is low enough so the level of liquid is above the HEIGHT setting.

Display shows WARMUP: Typically occurs when power is being applied to transmitter.

Display shows LOST:

Display is opposite of the measured value:

Indicates a weak power supply, bad wire connections or the sensor is out of the operational range.

Sensor is in a Fail-Safe state. The return sound pulses are not reaching the transducer. First, cycle power off and on, waiting 5 seconds between the off and on states. If problem persists, check the installation fitting against the Installation instructions in the manual.

Check the DISPLAY setting. AIR mode indicates the distance from the liquid to the sensor. LIQUID mode indicates the height of liquid in the tank. Change the DISPLAY mode from AIR to

LIQUID or vice versa to correct.

Transmitter indicates a current of 0 mA:

Transmitter jumps to a current reading between 19 and 20 mA:

Check the wiring for an open circuit. An open circuit is the most common issue with a 0 mA signal.

Check the installation of the transmitter. Bad installation fittings will cause false signals near the top of the tank, which typically translates to a signal between 19 and 20 mA. Also look for interference just below the transmitter. If the transmitter is installed in a metal fitting, switch to a plastic fitting.

Immediately check the wiring for a short circuit. The EchoSpan is current limited to 22 mA. Anything above 23 mA indicates a short circuit.
