Page 3: Introduction
1. Introduction The RL1600 Weigh Module Kit provides an extremely accurate method for weighing medium and large capacity tanks, hoppers, bins, and reactors. The design uses a double-ended shear beam load cell (700Ω bridge) and transmits the load through a clamping load plate to the center of the load cell. This design is very effective in providing for thermal expansion/contraction with little friction. -

2. Mechanical Installation 2.1 General Installation Guidelines for Weigh Modules The mounting surface for the base and top plate must be level. After installation, the top and bottom plates must be level within ±0.5°. If the mounting surfaces are not level, then shims and or grout may be used to level the mount. If possible, check that the module is level when the vessel is fully loaded because excessive deflections in legs and supporting structures may cause additional side forces which greatly affect accuracy. -

2. Determine where to position the module and in which direction it should be oriented. The RL1600 is designed to allow for lateral movement in the direction perpendicular to the longitudinal axis of the load cell. These weigh modules should be oriented so that the movement due to thermal expansion/contraction is perpendicular to the longitudinal axis. - Page 6 Assemble the modules by attaching the load cell to the load plate and clamp using the lockwashers and clamp screws. Then, insert the load pins through the base plate and load cell. Secure the load pins with washers and cotter pins. Note: The arrow on the load cell should point in the direction of the load.

3. Load Cell Wiring 1. Route the load cell cables so they will not be damaged or cut. Cable should not be routed near heat sources greater than 150 °F. Do not shorten any load cell cable. The load cell is temperature compensated with the supplied length of cable. -

4. Junction Box Connections, Adjustments & Calibration Refer to the Junction Box manual for trimming details. Refer to the indicator manual for system calibration details. 5. Troubleshooting If the system powers up and gives some type of stable digital readout that varies with the load on the system, any system problems are probably caused by factors other than the load cells. - Page 9 Check possible indicator malfunction by using a load cell simulator to input a known good signal into the indicator. Disconnect each load cell’s signal leads at the junction box and check individual load cell outputs with a multimeter. Then check input/output impedances for comparison with load cell manufacturer’s specifications.
