Calibration Instructions for Ultrasonic System - Sii Part # 34701515 Note: System is pre-calibrated at factory. Use only if re-calibration is required. SII Trim/Installation/Set-Up Procedure for Ultrasonic Level Sensor Assembly with DST-2421-C30 Sensor - P/N 34701515 1. Locate all parts listed on routing information. 2. Mark location for tank fitting and control box. Have QA approve marked locations as meeting drawing/customer requirements. 3. Install fitting as per standard procedure for the fitting listed. 4. Install scrap HDPE plate on tank to allow mounting of control box by: a. Sand area on tank that is larger than scrap HDPE plate so all welding will be done on freshly sanded surfaces. b. Sand scrap HDPE plate so all welding will be done on freshly sanded surfaces. c. Clean any loose sanded material. d. Extrusion weld scrap HDPE plate to tank in proper location with a minimum of ¼” fillet weld on all 4 sides of plate. 5. Align control box centered on scrap HDPE plate and attach with screws provided. 6. Temporarily install the ultrasonic level sensor in the tank fitting. 7. Install sensor cord/wires for testing/set-up of the level sensor assembly as per the pictures on page 1-2. Be careful to not bend the pins when removing the display circuit board. 8. Install factory test power cord/wires for testing/set-up of the level sensor assembly as per the pictures on page 1-2. 1 Revised by N.L.E. – 9/2/14 9. Double check connections and power up the unit. 10. Record the reading given by control box. The control box is recording the liquid depth assuming that the tank is 300” tall (the programmed default value). Subtract this number from 300 and write down for later use. This will be the “EMPTYd” setting in step 14.a. 11. The control box is partially preprogrammed for most of the inputs necessary. The list of preprogrammed parameters is shown on page 3. 12. SII personnel must set the parameters in the “bASIC” and “APP TY” settings. When navigating through the settings, use the ENTER button to select and save changes to a parameter setting. When the BACK button is used, any changes to the parameter settings will not be saved. 13. Press ENTER to select the bASIC programming menu and press ENTER again to open the menu. From the bASIC programming menu, SII personnel are to make the following changes: a. Navigate to and enter the CUSTOM settings. Using the UP and DOWN buttons to change the letters and pressing ENTER to select the correct letters, spell out “GALLON”. Press ENTER again to save the setting. b. Navigate to and enter the VOLUNI settings. Change the volume units to option 3 (GALLON) and press ENTER. c. Navigate to and enter the dECIML settings. Change the decimal places from 1 to 0 and press ENTER. 14. Press BACK until you see the bASIC programming menu. Then press UP or DOWN to navigate to the APP TY programming menu and enter that menu. From the APP TY programming menu, SII personnel are to make the following changes: a. Navigate to and enter the L CALC menu. Then enter the EMPTYd setting and input the value from step 10. This may need to be adjusted slightly to get a zero reading when the tank is empty due to tank bottom warpage variations. b. Also from the L CALC menu, move to the FULL D setting and enter the full tank height. The full tank height for this setting is defined as the distance from maximum fluid height to sensor face. This can be the “full” tank level as with Captor tanks; the sidewall gallonage 2 Revised by N.L.E. – 9/2/14 of a vertical tank (most industrial tanks) or a level defined by the sales drawing for the order. If any of these distances are less than 12” from the sensor face, set the Tank Overflow Height at 12” from the sensor face. The maximum fluid height cannot be less than a level 12” from the sensor face as this is the sensor blanking distance minimum. c. Next, move to the L MULT setting and input the gallons per inch. There are two methods to determine the gallons per inch: 1. Take the tank’s rated capacity and divide that by the height in inches at the tank full level. (Tank Capacity / [EMPTYd – FULL D]) 2. Value of hundreds of gallons per inch can be done by the chart below. This number may have to be adjusted slightly to compensate for tank bottom warpage, thickness and shrinkage variations. Tank Dia. 36 40 42 48 60 64 72 86 Gallon/inch 4.28 5.30 5.86 7.67 12.02 13.67 17.33 24.80 Tank Dia. 90 95 96 102 108 120 142 Gallon/inch 27.05 30.17 30.81 34.68 38.56 47.95 67.12 16. Exit mode and review tank reading. The unit should now be showing the gallonage of the empty tank. This number should be zero. The number must not be less than zero and not more than 20. If it is outside this range, adjustments to settings are necessary. Please review for error and adjust as necessary. 17. Remove sensor from tank top and check for FULL D settings used in Step 14.b. Verify that it is correct and that the unit is operating correctly. 18. If the settings check in steps 16 and 17, then unplug the power cord from the control box, disconnect power and sensor cords, package sensor for shipment, remove and package control box for shipment (for non-insulated tanks only – If this is an insulated tank installation, leave the control box mounted to the tank and follow foamed tank procedures). Make sure operator’s manuals for sensor and control box are packaged and sent with the unit. Print and send a copy of the mode/description page with the control box. Make sure to write the settings used in modes set by SII. 3 Revised by N.L.E. – 9/2/14 APG 1006A PREPROGRAMMED / DEFAULT SETTINGS FOR SNYDER INDUSTRIES 4 Revised by N.L.E. – 9/2/14 APG 1006A PREPROGRAMMED / DEFAULT SETTINGS FOR SNYDER INDUSTRIES (continued) 5 Revised by N.L.E. – 9/2/14 APG 1006A PREPROGRAMMED / DEFAULT SETTINGS FOR SNYDER INDUSTRIES (continued) 6 Revised by N.L.E. – 9/2/14 APG 1006A PREPROGRAMMED / DEFAULT SETTINGS FOR SNYDER INDUSTRIES (continued) 7 Revised by N.L.E. – 9/2/14 APG 1006A PREPROGRAMMED / DEFAULT SETTINGS FOR SNYDER INDUSTRIES (continued) 8 Revised by N.L.E. – 9/2/14
