    TABLE OF CONTENTS Introduction ............. . Page 1 Site Preparation .

  • Page 5: Introduction

    The totalizer enclosure contains a simple manifold assembly and a Cardinal PTG-3K Pressure Transducer for each load cell. The Pressure transducers convert the hydraulic pressure generated by the load cell to an analog signal that is easily trimmed and summed.

  • Page 6: Installation

    INSTALLATION In most installations it is advisable to locate and install the cells before the vessel or weighbridge is set in place. If the cell stand assemblies are installed with the vessel or weighbridge in place, extreme care should be taken to ensure that the stability of the vessel or weighbridge is maintained during installation of the load cell stands.
  • Page 7 INSTALLATION, CONT. Next, mount the totalizer enclosure on a wall as close to the digital weight indicator as possible. The totalizer enclosure should be mounted with at least 24 inches of clearance below it to allow room to connect the hydraulic tubes running from the cells to the bulkhead fittings. The 2 inch conduit from the scale should be stubbed up directly under the left side of the totalizer enclosure for the easiest installation.
  • Page 8 INSTALLATION, CONT. Load Cell Tubes Suppressor Package Manifold Fittings Figure No. 4 (3 & 4-Cell Totalizer Enclosure with Suppressor Package) Connect the load cell tubes to the totalizer enclosure bulkhead fittings. The tubes are normally installed with the tube for cell #1 being installed toward the front of the enclosure with the odd cells on the left and even cells on the right.

  • Page 9: Gauging Sst Hydraulic Load Cells

    INSTALLATION, CONT. Gauging SST Hydraulic Load Cells Filling and bleeding the system is a very simple procedure. Begin by filling the pressure pump with oil and attaching it to the inlet port located on the outside, bottom right side of the totalizer enclosure.
  • Page 10 INSTALLATION, CONT. Gauging SST Hydraulic Load Cells, Cont. 3. Open Manifold valve number one and pump oil through circuit number one until no air bubbles are seen coming out of the load cell end of the line. 4. Now remove the plug at the load cell inlet fitting and install the tube. 5.

  • Page 11: Gauging H2.5K And H5K Hydraulic Load Cells

    Gauging H2.5K and H5K Hydraulic Load Cells The procedure for gauging the H2.5K and H5K load cells used in Guardian scales is significantly different than gauging the SST series of load cells. Where the SST series use a simple set of feeler gauges, the H2.5 and H5 load cells use a special gauging pin to gauge the correct amount...
  • Page 12 It is very important that you do not over fill the load cell. Small capacity Cardinal cells contain a diaphragm that can be damaged by over pressure. If the amount of oil in the cell is not known ALWAYS bleed all oil out of the cell to lower the piston and add fluid to bring it up to the correct height.

    FINAL ASSEMBLY IMPORTANT INSTALLATION NOTES! THE PURCHASERS OF FLOOR STAND TANK/HOPPER SCALE COMPONENTS ARE ADVISED TO INSTALL SAFETY STAY RODS. CARDINAL SCALE MANUFACTURING CO. (CSMC) WILL NOT BE RESPONSIBLE FOR THE STABILITY OF THE TANK. IT IS RECOMMENDED THAT ALL PIPE CONNECTIONS TO THE TANK BE FLEXIBLE.

  • Page 15: Indicator Installation

    INDICATOR INSTALLATION 1. Install the digital indicator. 2. The indicator cable is terminated at the Surge Suppression box located in the front door of the Totalizer enclosure. Make sure the surge suppression box is grounded back to the indicator and the AC power ground. Failure to provide a good ground will make the surge suppression inoperative.
  • Page 16 Refer to Figure No. 12. Figure No. 12 – J-Box Trim Assy. 5. If necessary the Guardian Linearization software in the indicator can be used to tweak out any small errors. 1780-M057-O1 Rev C  Hydraulic Floor Stand Tank/Hopper...

    MAINTENANCE Like any other scale the Guardian system needs routine maintenance to keep it working to its potential. Since there are no electronic components in the scale itself this is simplified on the Guardian.

  • Page 18: Troubleshooting

    TROUBLESHOOTING SST Hydraulic Load Cells If you are having a problem with a cell loosing fluid (it will always be weighing light) remove the gauge port and see if the gauge will go into the cell. If not, we need to determine for sure that the cell has lost oil.

  • Page 20: Ptg-3K Transducer Shooting

    TROUBLESHOOTING, CONT. PTG-3K Transducer The Cardinal PTG-3K pressure transducer is a simple device to convert hydraulic pressure into a voltage output that can be easily summed and trimmed. It can be checked much the same as a standard strain gauge based load cell.

  • Page 21: Recommended Sealing Procedure

    RECOMMENDED SEALING PROCEDURE If your Guardian Hydraulic Scale System is used in a commercial application and your local metrology laws require the use of physical sealing, a lead and wire security seal can be installed to prevent access to the interior components of the Totalizer Enclosure.
