2.1 Foundation Installation
For installation, reference the foundation drawings supplied with the scale. · Do not start construction of the foundation without having certified prints. · Pour the scale slab(s). · Pour the approach slab and, if applicable, intermediate section over rebar or optional anchor bolts. · Use Handbook 44 and AAR Handbook Guidelines for Legal for Trade
NOTE: Anchor bolts should protrude from the concrete enough for the lower base plates to be secured onto them.=

IMPORTANT: Failure to heed the following could result in damage to the concrete and equipment.

The concrete foundation must cure in a moist state for at least seven days (three days for high-early concrete). At seven days, standard concrete is approximately 75% of its maximum strength and can handle moderate loads. Loading of a slab before it reaches 75% of maximum strength may damage the foundation. * Standard concrete does not reach full strength until after a 28-day cure.

3.0 Junction Box and Grounding
Electrical conduit is pre-installed at the factory and only needs to be connected between the modules and from the modules to the junction box. Following conduit work, load cell cables are routed through each conduit from the load cells to the junction box. All load cell cabling used for this installation comes in the shipping container. The layout pattern for the electrical conduit on a three module rail scale installation is shown in Figure 3-1.

Junction Box and Grounding
3.1 Load Cells to Junction Box
Each load cell is equipped with 30 ft of load cell cable, sufficient to reach a centrally-located junction box on standard scales. A conduit adapter and a 14 in section of 3/4 in flexible conduit is supplied for both ends of each load cell cable located at the load cell and at the junction box. The main conduit that runs between these 14 in flexible end sections are 3/4 in galvanized metal. The conduit is already installed on the deck.
NOTE: Flexible conduit can not come in contact with the ground. Plastic tie wraps are included in the hardware shipping box and should be used to tie up the flexible conduit.
If using a single B module, some of the conduit runs are not used. These conduit runs are used when more than one B modules are installed.
3.2 Junction Box Connections
Each junction box is large enough to hold the summing board, transient protection devices, packaged desiccant and extra load cell cable coiled inside the enclosure. An industrial corrosion inhibitor and desiccant such as the RLWS Industrial Corrosion Inhibitor (PN 16037) should be added to the junction box enclosure before final closure.
NOTE: Summing card mounted within the junction box is used to make all cable terminal connections. All terminal pins are clearly marked as to function.
3.3 Junction Box to Indicator
Fifty eight (58) feet of six-wire homerun cable is supplied for wiring the junction box to the indicator. It is run in 3/4 in galvanized metal conduit from the junction box to the indicator. Conduit for this purpose is to be obtained locally. A 30 in flexible conduit section and conduit connector is provided where this cable exits the junction box. Do not run any other electrical cables in or near the conduit to the indicator.
3.4 Indicator to Peripherals
All 3/4 in conduit for cabling from the indicator to remote displays and other peripheral devices is to be obtained locally. Conduit runs may be buried in a trench or secured above ground. Use separate conduit runs for AC power and DC data lines to avoid interference. As a general guideline, run AC and DC cables in separate trenches if possible. If DC data cables must run in the same trench as AC power lines, separate cables as much as possible (preferably more than 34 in apart).
3.5 Single-Point Ground Conductor
A bare 10 gauge solid wire is to be run from the scale frame to the grounding lug on the junction box then underground to the main AC power earth ground. If the DC transient protection board is installed, the ground conductor should also be connected to the transient protection board’s ground lug.
3.6 Electrical Ground Connections
IMPORTANT: A single-point grounding system is required. Improper grounding systems can cause corrupted data from ground loop current flows and costly lightning damage to electronics.
Always strive for a single-point grounding system. Do not drive ground rods at the scale location which establishes separate earth grounds for the scale. These separate earth grounds will not share the same zero reference as the existing earth ground for the AC power system. This difference in electrical potential invites ground-loop current flow between the separate grounds, often corrupting serial data like RS-232, which depends on a stable zero reference.
In addition, a separate earth ground system at the scale can actually invite lightning or power surge damage:
· A minor power line surge should immediately be shunted to ground. If a separate ground system exists at the scale with a lower potential than the main ground, the surge may travel out to the scale ground rod, damaging load cells on its way.
· A nearby lightning ground strike may instantly raise the zero potential of a ground rod at the scale location, while leaving the scale house ground rod unaffected. That lightning surge will now take the easiest path to the lower- potential ground–through the scale wiring and back to the scale house ground, possibly damaging the indicator on its way.
Therefore, the best grounding system for the scale is the same grounding system used for the incoming AC power system. The 120 VAC power source used to power the indicator will be connected to an existing earth grounded rod system at the scale house or other building where the indicator is located. This should consist of a double ground rod system of two 5/8 inx 8 ft copper rods driven 8 ft deep at the service entrance where the local utility company brings their lines into the building.

13

Survivor PL – Low Profile Modular Railroad Track Scale
The local utility company can test the resistance of the existing ground rods with a clamp-on megohmeter that measures zero resistance. A reading of 3¾ or less is acceptable as a ground. If the test determines that the grounding system is inadequate, the utility company can suggest methods to improve the system. It’s crucial that the scale owner authorize and make the recommended improvements to assure an adequate electrical ground. Do not connect the scale to the AC power supply until the grounding system is adequate.
Be certain each load cell grounding strap is securely connected to the top plate and bottom plate of each load cell mount. There should be metal-to-metal contact with no presence of paint or grout. This strap is designed to channel power surges on the deck around–rather than through–the load cell to ground

Grounding Strap

Figure 3-2. Grounding Strap on Load Cell Mount
These, and all, ground connections must be torqued to a specified value and retorqued at regular service intervals. A thick coating of anti-oxidant grease should be maintained on all ground connections to prevent corrosion.
A separate grounding system conductor must extend uninterrupted from the main service panel ground to the scale to protect load cells and scale wiring from lightning and other transient damage. This ground wire conductor must be an unsheathed #10 copper wire or larger. Run the bare ground wire conductor intact from the AC power ground rod to the scale in a separate trench. Bring the wire up from the trench near the junction box and attach it to the ground lug of the junction box. A #10 bare ground wire is run from the ground lug of the junction box to one of the junction box mounting studs on the scale frame, thus grounding the scale frame to the same single-point ground as the AC power for the indicator.

Survivor PL – Low Profile Modular Railroad Track Scale

4.0 Trimming and Calibration

IMPORTANT: See the Association of American Railroads (AAR Scale Handbook) at http://www.aar.org for specifications on rail testing procedures.
Load cells are trimmed as paired sections, referred to as Section Signal Trimming, until each sectional output is equal. Adjustments to each section should be done at least twice.

4.1 Equipment Required
This trimming operation can be done using a weight cart parked in various locations on the scale. Final verification of equal output trimming, however, will require test weights to be placed on the deck in various locations.

Trim Load Cells
Connect all load cells to the summing board terminals in the junction box.
Connect the main interface cable from the junction box to the indicator.
Turn on the indicator.
Turn all load cell potentiometers in the junction box clockwise until a clicking noise is heard when continuing turning. This eliminates any initial resistance so all signals are at full strength.
Park the loaded weight cart in the middle of the scale, with the wheels centered over the center line of the two end load cell mounts (Figure 4-2).
Record the indicator reading.

7. Move the weight cart to the next load cell pair center line and record the indicator reading. 8. Continue until all pair readings have been recorded. 9. Choose the lowest reading as the reference section, do not adjust this reading. 10. Using the section potentiometers, reposition the weight cart on the other sections and trim the sections to match the
reading of the reference section. 11. Recheck section readings a second time as the adjustment made may be interactive. 12. Repeat the procedure for the paired sections on Scale Section 2. 13. Place railroad test car on each section for final certification.

Trimming and Calibration
4.2.1 Static Testing of a Track Scale A shift test is required to ensure the scale is preforming within applicable tolerance and to verify a rail car can be accurately weighed from any direction or at any position on the scale.
Begin the shift test by documenting the current readings for the sections, in both directions, before any repairs or adjustments are made. After repairs and adjustments are made, document the readings again. A weight of at least 80,000 lb (36,300 kg) must be used for track scale certification, except for Interim Approval (returning a scale temporarily to service after repairs, refer to the AAR Scale Handbook).
Sections of the scale need to be numbered 1, 2, 3 etc., from left to right when standing at the indicator, facing the scale deck (see Figure 4-1). Normal sectional placement positions of a scale Test Weight Load, when performing a shift test, are designated from left to right (view from the indicator) as 1R, 2L, 2, 2R, 3L 3, 3R, etc. The numbers represent the sections, the letters (when affixed) indicate whether the body of the Test Weight Load lies to the left or right of the section, with one pair of wheels or jacks directly over the section.
The following are standard combinations of normal Test Weight Load placement positions (using a four-section scale as an example).
· 1R, 2, 3, 4L · 1R, 2L, 2R, 3L, 3R, 4L When testing a two-section scale, the standard combination of normal test car positions is 1R, Center 2L.
When using self-propelled test cars, place the entire car on the left, center and right end of the scale load receiving element. Test Weight Cars shall be uncoupled at both ends to avoid coupler error.
NOTE: Refer to the AAR Scale Handbook for more information.
4.2.2 Strain Test In addition to the standard test, the scale should be strain tested by using a load and a scale Test Weight Load or known test weight.
1. Place the load on the scale and record its weight.
2. Add the Test Weight Load or test weight to the scale.
3. Record the combined weight and subtract the load weight from the combined weight of the load and the test weight. The difference between the value of the load and the load plus the test weight should be equal to the test weight. If not, the difference must not exceed the applicable tolerance as applied to the test weight.
NOTE: One half of the rail car can be used as a load if the scale is too short to accommodate an entire rail car plus the test weight load or test weight.
Refer to the AAR Scale Handbook for more information.
