Note: Always install the 2” Viton gasket with the LA19-5061. The G threaded version of the Ricochet will not seal unless the gasket is installed properly. Never overtighten the transmitter within the fitting. Always check for leaks prior to system start-up. When finished, re-assemble the display using steps 1 - 5 in reverse. When re-assembling the circuit boards be careful NOT to over-tighten the screws. Screw Terminal Connector J5 Wiring and Electrical: A battery supply of 18 VDC is used to power the LA19 transmitter and display. The system should never exceed a maximum of 36 volts DC. Electrical wiring of the sensor should be performed in accordance with all applicable national, state, and local codes. Ribbon Cable Connector Input Signal Board Material Compatibility: The Ricochet™ transmitter housing is made of Polypropylene (PP). The transducer is made of Polyvinylidene Fluoride (PVDF). The display is made of a High impact-resistant ABS plastic. Make sure that the model which you have selected is chemically compatible with the application liquids it will contact. Enclosure: While the transmitter and display are liquid-resistant when installed properly, it is not designed to be immersed. It should be mounted in such a way that the enclosure and diaphragm do not come into contact with fluid. Make a Fail-Safe System: Design a fail-safe system that accommodates the possibility of transmitter or power failure. In critical applications, FLOWLINE recommends the use of redundant backup systems and alarms in addition to the primary system. Display Board Disassembly Transmitter: The transmitter arrives from the factory pre-calibrated and pre-assembled. Use the following instructions below for wiring to the LA19. 1. First, remove the cap of the transmitter: 2. Look for the terminal block with two terminals. 3. Remove the terminal block to wire the LA19.

Do not install LA19 at an angle Avoid Interference from side of tank Avoid Interference from obstructions in tank LA19 will not operate in vacuum VACUUM CALIBRATION CALIBRATION Step Six Step Seven The LA19 is factory calibrated with a fixed measurement span of 12 feet. The 4 mA position is located 144" from the transducer face of the level transmitter. The 20 mA position is located 6 inches from the transducer face. Refer to the current to distance and distance to current conversion charts below for reading the current output. CALIBRATION The display must be calibrated to both a low level (LO) and high level (HI) in the tank. The LO setting is made by the LO potentiometer (R11) located below the display. The HI setting is made by the HI potentiometer (R9) located to the right of the display. Simply set the level of the tank to its lowest position and adjust the LO control to display the desired reading. Next, set the level of the tank to its highest position and adjust the HI control to display the desired reading. Complete the calibration procedure by making any minor adjustments to the LO and HI controls.

During normal operation, the LED will be ON continuously to indicate that the transmitter has power and a strong echo signal return strength. POWER LED 12-36 VDC (-) (+) GND Should the LED begin to FLASH, it indicates that the transmitter has no signal return strength and the device has gone into a failsafe condition. During the fail-safe condition, the current will increase up to 22 mA and hold until the acoustic signal is reacquired. Once re-acquired, the LED will turn back ON continuously and the current will indicate the appropriate measured value. 4-20 mA RICOCHET Alphasonic Transmitter Example: For a tank than is 100” tall with a full level of 90”. 1. Set the level to the empty position. 2. Adjust LO potentiometer to 0.0 on the display. 3. Set level to the full position (90” of liquid). 4. Adjust HI potentiometer to 90.0 on the display. To show gallons, calculate the volume of the tank in gallons at the 90” level. Substitute the new gallon measurement for the 90.0 value when setting the HI potentiometer. An optional method of calibration is to point the level transmitter at a fixed object outside of the tank. First, measure the distance from the bottom of the transducer to the lowest and highest level of liquid. Next, place the transmitter at the lowest level distance and adjust the LO potentiometer to the desired setting. Then, place the transmitter at the highest setting and adjust the HO potentiometer to the desired setting. Complete the calibration procedure by making any minor adjustments to the LO and HI controls. DECIMAL POINT SELECTION The decimal point jumper array (JP1) is located to the upper right corner of the display board. Place a jumper across the bottom pins for a display of of 199.9, across the middle pins for a display of 19.99, and across the top pins for a display of 1.999. MAINTENANCE Step Eight General: The LA19 battery powered level transmitter and display 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. Power: Make Sure that all power to the transmitter, controller and/or power supply is completely disconnected. 2. Sensor Removal: In all through-wall installations, make sure that the tank is drained well below the sensor prior to removal. Carefully, remove the sensor from the installation. 3.
