Section 1: General Information INTRODUCTION This manual provides general installation and maintenance instructions for the Fairbanks Scales 9120 Series Omnicell. Almost every installation is different, so please adjust the following information, as needed, for your application. Specifications, parameters and application notes are included. This manual is meant to give general instructions for applying the Omnicell considering its inherent capabilities and limitations; it is not meant to be a scale design manual. Questions concerning specific applications should be directed to the appropriate Product manager. For complete 9120 Series installation you will also need to reference the necessary instrumentation manual. DESCRIPTION Fairbanks Scales Omnicells are a combination of two main components: Mounting assembly (captivates the load cell and provides means to fasten to the vessel and flooring). Load cell (the actual weight detecting device). The 9120 Series Omnicells will arrive preassembled, excluding the load cells. This mounting assembly is specifically designed to be installed without the load cell for easy installation. Load cell installation is done quickly, just prior to calibration. The 9120 Series Omnicells are available in standard capacities ranging from 7.5 t to 100 t. (t = metric tonne.) Higher capacities are available, contact the appropriate Product Manager. The load cells are constructed from stainless steel and are a rocker-column design. The mounting assembly is available in either a zinc-plated or cast mild steel or stainless steel construction. These Omnicells can be welded to the load carrier and the foundation. Welding eliminates problems of getting holes on the top and bottom line up. These assemblies are designed for a welded installation, so welding will not cause any service issues (load cell replacement). 11/12 6 51267 Rev. 2
Section 1: General Information The 9120 Series can be installed using mechanical fasteners (nuts and bolts). This installation method eliminates the need for onsite welding. It can also be a combination of welding and mechanical fasteners. For example, the top plate can use mechanical fasteners and the base assembly can be welded. Omnicell systems principle causes of problems are because of mechanical restrictions to, and interaction with, the weigh vessel. The cause is invariable excessive vessel or support deflection that needs be identified, if possible, during the design phase. Close attention should be made to ladders, catwalks, piping, and any items that restrict deflection of the vessel. The 9120 Series Omnicells are commercially approved for applications in the U.S., however Fairbanks Scales recommends contacting your local Weight and Measures Office prior to beginning any Omnicell installation that requires commercial approval.

Section 2: Company Service Information OVERVIEW Physical Installation Notes Check all devices for proper operation. If any error messages occur, refer to Troubleshooting or the proper manual of that device. Only those charges which are incurred as a result of the equipment's inability to be adjusted to performance specifications may be charged to warranty. No physical alterations (mounting holes, etc.) are allowed during installation. The installing technician is responsible that all personnel are fully trained and familiar with the equipment's capabilities and limitations before the installation is considered complete. All electrical assemblies must be replaced as assemblies or units. Replacement of individual components is not allowed. These components must be returned intact for replacement credit per normal procedures. All electronic and mechanical adjustments are considered to be part of the installation, and are included in the installation charge(s). Included is any required computer programming or upgrades. Included are any accuracy and/or operational specification changes. The AC receptacle / outlet shall be located near the Instrument and easily accessible. Electrical connections other than those specified may not be performed. Conferring with our Client The technician must be prepared to recommend the arrangement of components which provide the most efficient layout, utilizing the equipment to the best possible advantage. The warranty policy must be explained and reviewed with the customer. 11/12 9 51267 Rev. 2
Section 2: Company Service Information Installation Considerations Thorough application review should be conducted before, during and after installation: Determining Omnicell Capacity - Sizing the Omnicell (general rule) Take the overall live and dead load of the vessel. Multiply by 2, then divide by the number of support points (legs, typically). For example: 4 Legs 26,000 lbs dead load 74,000 lbs live load 26,000 + 74,000 100,000 x 2 200,000 4 50,000 lb for each Omnicell Loading The vessel will have 3, or more, tank legs. The Omnicells should be level and, under extreme cases, shimmed, so that the load is roughly equal on each Omnicell. Flooring - A thorough inspection of the flooring s deflections must be considered before installing an Omnicell system. Flooring must be rigid enough to handle the total load without deflection. Thermal contraction and expansion Horizontal vessels, in direct sunlight, can create thermal expansion issues. The floating rocker column design of the 9120 Series Omnicell easily handles most thermal expansion/contraction issues. Uplift and lateral constraints In extreme conditions (high winds or seismic activity) uplift and lateral stresses on the Omnicell system are a concern and should be considered when choosing the best Omnicell for the application. The 9120 Series Omnicell provides a degree of built-in uplift and lateral checking, refer to the product QuickFacts for a detailed explanation of the forces. In extreme conditions, additional checking is recommended. Isolate vessel Many external factors affect the accuracy and stability of an Omnicell system. Load cell signals can be affected by EMF sources such as electric forklifts, pumps, motors, etc. A well-isolated tank will provide more reliable results with fewer problems. 11/12 12 51267 Rev. 2
Section 2: Company Service Information Eliminate mechanical constraints The vessel should be fully supported on the Omnicells. Reduce or eliminate any mechanical issues which will interfere with the vessel s deflection, such as: rigid vertical or horizontal piping (use flexible piping when connecting to the vessel whenever possible), ladders, catwalks, etc. Orientation Orientation of the 9120 Series Omnicell isn t critical because of the rocker load cell design, however it is recommended positioning the load cell cables away from traffic areas. Heated or chilled vessels Consult with the appropriate Product Manager for any application with vessels that heat or chill the product inside the vessel. In these cases, special consideration may be required to isolate the temperatures. Load cell cabling The load cell cables should be routed away from areas where they could be damaged. Use drip loops at both the load cell and the junction box ends. Hazardous area If the Omnicells will be installed in a Hazardous Area, a document is required from the end user stating the Class, Division, and Group. 11/12 13 51267 Rev. 2

Section 4: Electrical Installation A. Analog Junction box Installation for analog instruments 1. Introduction The analog j-box should be installed on the vessel, and in an easily accessible location, whenever possible. It is recommended that it be installed in a vertical position. 2. Description The analog j-box has four (5) terminal blocks to connect four (4) load cells and one (1) for a cable that connects to the analog instrument. Load cells are adjusted using adjusting potentiometers. 3. Installation a. Boxes: The box has tabs for bolting to mounting brackets on the side of the vessel. Attach the ground wire lug to one of the mounting bolt studs and tighten securely to provide a good electrical ground. b. Wiring: Cable used in all wiring must be a minimum of 24 AWG. Use cable 20903 or equivalent. Load cell wiring color codes LCF-HR4020 Black Green Red White YYeel ll looww (-) Excitation (+) Excitation (-) Signal (+) Signal Shield 11/12 42 51267 Rev. 2
Section 4: Electrical Installation B. Wiring SSCs and PPSs for Intalogix systems 1. Introduction Intalogix systems utilize smart sectional controllers (SSCs) and pit power supplies (PPSes) for load cell excitation and signal processing. 2. Description SSC boxes have four (4) terminals, two (2) for load cells, and two (2) for interconnecting to other SSC boxes or terminating to a pit power supply. Make sure the proper number of SSC boxes are order based on the application requirements. All cell and scale adjustments are made via the Intalogix system instrument. 3. Installation Boxes: The box has tabs for bolting to adapters on the side of the modules. Wiring: Cable used in all wiring must be a minimum of 18 AWG. Use cable 17204 or 17246. Use appropriate service manual for the instrument being installed. a. Smart Sectional Controller Wire cells into each section s SSC per the appropriate manual. Remember that odd numbered cells go to TB1 location, and even numbered cells go to TB2 location. Load cell drain wires connect to the ground lug on the sectional controller box exterior. b. Grounding SSCs Intalogix systems must have two (2) ground rods in the pit for proper connection. Pit power supplies use a ground separate from the steel and SSC ground rod. c. Instrument-to-PPS cable connection Prepare the cable ends in the standard manner. Use the appropriate manual for wiring instructions of all SSCs and pit power supplies. Connect the instrument interface cable to the instrument in the in the scale house per the instructions in the appropriate indicator service manual. Note: Intalogix installations utilize a different numbering system for load cells because of digital addressing of the SSCs. Number the load cells as follows: With respect to the following starting position, face the vessel from where the instrument is located. The cell at the upper left (far side) of the platform is Cell 1. The cell positions along the far side will be odd cell number, and the near side locations will be even cell numbers. Note: SSCs have connections for two (2) load cells, TB1 and TB2. The oddnumbered cell should go to the TB1 connection, and the even-numbered cell to the TB2 connection. 11/12 44 51267 Rev. 2
Section 5: Maintenance Scale Maintenance 1. Check for accumulations of solid material under the Omnicells that may affect the accuracy (ice, frozen mud, debris). 2. Check to see that the customer is doing routine cleaning around the vessel. 3. Inspect load cells for damage to the ends/cables; check cups and O rings for damage. 4. The load cell bearing cups should be inspected, cleaned, and greased annually. 5. Inspect and adjust all check bolts (if applicable) using anti-seize on the threads. 6. Check for all clearances around the scale for any obstructions or interference with the free movement of the platform. 7. Check all check bolt clearances both with and without a concentrated load over each leg (support point), one at a time. 8. Check all load cells for plumb and level. 9. Inspect the boxes for leaks; the interior should be clean and dry. If there is moisture inside, clean and dry it thoroughly. Check all connections at the terminal blocks to ensure they are tight. 11/12 46 51267 Rev. 2
