If you have a non-standard installation or setup requirement that is not addressed here, please refer to the EchoSpan® Manual or other support documentation located at flowline.com. WE DO YOUR LEVEL BEST Thank you for purchasing EchoSpan®. The sensor provides integrated LCD and three push-button configuration. This quick start includes everything you’ll need to get the sensor up and running. COMPONENTS Depending on how the sensor part number that was shipped, EchoSpan® comes with a Viton® gasket for installation and the Quick Start. EchoSpan® LU81-5101 & LU81-5161 LU83-5101 & LU83-5161 LU84-5101 & LU84-5161 Viton® gasket (2”) P/N: 200129 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. 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. Note: If using the Flowline LM90-1001 (liquid tight fitting) on the ½” conduit, the cable minimum is 0.170” (4.3mm) and the maximum is 0.450” (11.4mm). | 2 QS301550 Rev D1 MOUNTING THE ECHOSPAN ® The sensor should always be mounted perpendicular to the liquid surface using the provided Viton® mounting gasket. Insure that there are no restrictions or obstacles in the path of the acoustic signal. For further mounting information, please refer to the EchoSpan® manual at www.flowline.com. Mounting with a Tank Adapter: Select a tank adapter fitting, such as the LM52-2890. Mounting in Riser: As installations with tall, narrow risers can impede the acoustic signal. 2" diameter risers should be no taller than 5". Larger diameter risers should be no taller than 12". For best results, follow a 2:1 Height to Inner Diameter ratio (example: 8” High to 4” Inner Diameter). Mounting in Side Mount Bracket: Use Flowline's LM50-1001 side mount bracket. LM50-1001 Shown QS301550 Rev D1 3 | IMPORTANT MOUNTING GUIDELINES 1) Never mount the sensor at an angle. 2) Liquid should never enter the dead band. 3) Mount at least 3” from the side wall. 4) Never mount the sensor in a vacuum. 5) Do not obstruct the sensor’s beam width. Mounting with a Stand-Pipe: A stand-pipe may be used to dampen turbulence, separate surface foam from the point of measurement or increase performance in heavy vapor. When mounting the sensor in a stand-pipe, the minimum diameter of the pipe is 3”. Larger diameter pipes can be used. The pipe should be attached with a coupling or tank adapter and reducer bushing. Avoid the use of multiple pipe fittings when possible. An ideal mount would be to select a 3” tank adapter (S x T or S x S) and connect the pipe to the inside slip and use a reducer bushing to attach the sensor (see example below). 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. Cut the bottom end of the pipe at 45° and drill a 1/4” pressure equalization hole within the sensor’s dead band. Locate the stand-pipe away from pump outlets and/or other sources of substantial turbulence which might cause the liquid in the pipe to oscillate. 3” x 2” Reducer Bushing (TxT) 3” Tank Adapter (S x T) 3” PVC Pipe Stand-Pipe Example | 4 Stand-Pipe Mounting QS301550 Rev D1 WIRING THE ECHOSPAN ® The following wiring diagram can be used for the 4-20 mA output of the EchoSpan®. Notes on 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. The sensor must be chemically compatible with the application. Design a fail-safe system for possible sensor and/or power failure. Never use the sensor in classified hazardous environments. Wiring to Common Devices Wiring to Loop Display QS301550 Rev D1 Wiring to Generic PLC Wiring to DataView™ LI55 series 5 | TOP-LEVEL MENU The sensor is configured with the three buttons on the sensor face (UP, DOWN and SELECT) and the sensor’s LCD. To access the sensor’s Toplevel menu, simply hold down the SELECT button for five seconds. The display menu will automatically begin to scroll through the TOP-LEVEL MENU. When the menu scrolls to an item you wish to configure, simply press the SELECT button to choose that item. The TOP-LEVEL MENU will continue to scroll through the following (UNITS – TANK – SAFE – TGCAL – VALUES – HELP – RUN), If you miss your selection, it will appear again shortly. To return to the TOP-LEVEL MENU, press SELECT when EXIT appears. To return to Operational Mode of the sensor, press SELECT when RUN appears in the TOP-LEVEL MENU. Note: To speed up the scrolling of the values on the display, hold down the SELECT button while holding down the UP or DOWN buttons. Set Units: The EchoSpan® displays information in the following units: inches, feet, centimeters, meters or percentage. The value shown on the display represents the amount of liquid in the tank. 1) In TOP-LEVEL MENU mode, select UNITS. 2) Next, select INCHES, FEET, CM, METERS or PERCNT. SAVED will display. 3) Finally, select EXIT to return to the TOP-LEVEL MENU. Measuring Sensor Height and Fill-Height: HEIGHT – Distance from the transducer face to the bottom of the tank. FILL-H – Maximum fill height of the liquid from the bottom of the tank. Note: The Height and Fill Height settings also determine the 4 to 20 mA current span. The Height setting determines the 4mA position and the Fill-H setting determines the 20 mA position. | 6 QS301550 Rev D1 Set Height and Fill Height: This setting customizes the reading for your installation. Follow these instructions to set the height and fill height for your tank: 1) In TOP-LEVEL MENU mode, select TANK. 2) Select HEIGHT. 3) Use the UP and DOWN buttons, set the HEIGHT of your tank. 4) To enter the value, press and hold SELECT for 2 seconds and release. SAVED will display. HEIGHT is now set. 5) Select FILL-H. 6) Use the UP and DOWN buttons, set the HEIGHT of your tank. 7) To enter the value, press and hold SELECT for 2 seconds and release. SAVED will display. FILL-H is now set. 8) Select EXIT to return to the TOP-LEVEL MENU. 9) Select RUN to return to Operational Mode. Note: The Height and Fill Height settings also determine the 4 to 20 mA current span. The Height setting determines the 4mA position and the Fill-H setting determines the 20 mA position. Select Fail-Safe Output / LOST: In the event the sensor does not receive an echo, the Fail-Safe Current Output or LOST setting can be set to output a current of 4mA, 20mA, 21mA, 22mA or HOLD (last known value). During failsafe, the display will read LOST. 1) In TOP-LEVEL MENU mode, select SAFE. 2) Select 4mA, 20mA, 21mA, 22mA or HOLD. SAVED will display. 3) Select EXIT to return to the TOP-LEVEL MENU.
