Introduction The RL4050LS can be used in a variety of tension weighing applications. Especially useful in marine and train applications, this electronic load shackle can be used in machinery lifting, towing, freight handling, and any other place where an ordinary shackle would be used. Backed with testing results from 40 to 180 F., the RL4050LS is available in capacities ranging from 5 tons to 100 tons. The unit is constructed of alloy steel that has been painted to provide additional protection against the elements Caution The installation should be planned by a qualified structural engineer. Each installation is unique, and this manual is meant to serve only as a general guideline for installation. Authorized distributors and their employees can view or download this manual from the Rice Lake Weighing Systems distributor site at 1

4 2. General Installation of the Load Shackle It is important to remember to always use load shackles below the specified load rating. The load must be applied in the primary load axis. Extraneous loads or compound stress must be avoided. Ensure that safety hardware, such as safety chains and rods, is supplied, when failure could cause injury or damage. And routinely inspect for signs of damage, excessive wear, or corrosion. If found, replace the unit. Do not jerk the load or apply the load at a high rate of speed. 1. Determine where the RL4050LS is to be placed. 2. Use the proper shackling hardware to ensure the unit is safe. 3. Connect the cable to the indicator (see Section 3 on load shackle wiring). Note: For optimum accuracy, use ISO washers and load in the center of the load pin. For safety, always use the supplied cotter pin. 3. Load Cell Wiring Each RL4050LS comes with a standard 25 foot weather resistant poly cable. Additional cable length, SS armored cable or Teflon cable is also available. 1. Route the cable from the load shackle using the six pin molex connector. Make sure the cable does not get crimped, damaged, or cut. The cable should not be routed near heat sources greater than 150 F. Do not shorten any load cell cable. 2. Connect wiring from the the load shackle to the indicator using the cable color code in the table shown below. Cable Color Red Black Green White Signal + Excitation - Excitation + Signal - Signal 3. The cable can be hooked directly to the indicator, no junction box is necessary. 4. Refer to the indicator manual for system calibration guidelines. Teflon is a registered trademark of E.I. Dupont 2

6 5. Limited Warranty Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed by the Distributor/OEM and accepted by RLWS. All weigh modules are warranted against defects in materials and workmanship for two (2) years. RLWS warrants that the equipment sold hereunder will conform to the current written specifications authorized by RLWS. RLWS warrants the equipment against faulty workmanship and defective materials. If any equipment fails to conform to these warranties, RLWS will, at its option, repair or replace such goods returned within the warranty period subject to the following conditions: Upon discovery by Buyer of such non-conformity, RLWS will be given prompt written notice with a detailed explanation of the alleged deficiencies. Individual electronic components returned to RLWS for warranty purposes must be packaged to prevent electrostatic discharge (ESD) damage in shipment. Packaging requirements are listed in a publication, Protecting Your Components From Static Damage in Shipment, available from RLWS Equipment Return Department. Examination of such equipment by RLWS confirms that the non-conformity actually exists, and was not caused by accident, misuse, neglect, alteration, improper installa tion, improper repair or improper testing; RLWS shall be the sole judge of all alleged non-conformities. Such equipment has not been modified, altered, or changed by any person other than RLWS or its duly authorized repair agents. RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible for shipping charges both ways. In no event will RLWS be responsible for travel time or on-location repairs, including assembly or disassembly of equipment, nor will RLWS be liable for the cost of any repairs made by others. THESE WARRANTIES EXCLUDE ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANT- ABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER RLWS NOR DISTRIBUTOR WILL, IN ANY EVENT, BE LIABLE FOR INCIDENTAL OR CONSE- QUENTIAL DAMAGES.
