Overload Protection Springs
Lift up Protection Screw
Overload Protection Screw
All seven models of the 10" x 10" and 12"x12" SL series have stainless steel covers and frame systems. All models use a single point load cell. The 10, 20, 30, 50, and 100 lb models come standard with a potted single point load cell that offers extra protection against water infiltration but is not designed for washdown use. The 30, 50, and 100 lb models can also be supplied with an RL1140 stainless steel load cell. Extra load cell protection is also available in optional stainless steel “clamshells” which enclose the load cell. See Section 5.0 for information about clamshell installation. All load cells come with
The SL series scales use a sensitive 4-point, spring-plate suspension to minimize shock and overload damage susceptible of light-capacity scales. The system uses a bolt and an overload protection spring at each of four loading points beneath the top cover (see Figure 1-1). Each spring is set for a specific tension so that it will compress to prevent overload damage. If a potentia at that corner compresses. When the spring compresses, the load is taken off the load cell. This eliminates the possibility of overloading the load cell. Likewise, if a load more than 150% of total capacity is placed anywhere on the deck, the springs will compress and remove the load from the load cell.
In addition to the overload protection spring, the SL models inc beneath the load cell to help prevent overload damage.
To protect the load cell from being acciden spider, a lift up protection screw is incorporated into the design (see Figure 1-2).

Larger models in the series use mild steel frames and stainless steel deck covers for light washdown with a damp sponge. All models are available with mild steel or optional stainless steel underbody frame construction. The standard load cell is a single point load cell. Options include a stainless steel RL1140 load cell for 12" x 12" and 12" x 18" models and protective stainless steel clamshells for all models using a single point load cell. All load cells come with 10 feet of cabling.

2.1 Leveling Scale

Remove the scale from the shipping container and place it in the desired location. Lift off the deck cover and locate the bubble level. Adjust the four corner feet until the scale is level and all feet contact the support surface so the scale does not rock. Lock the jam nuts on the feet when the final level is correct.

2.2 Connecting the Load Cell Cable

All models come with 10 feet of color-coded load cell cable.
Do not cut this cable. The load cell is temperature-compensated for an exact cable length of 10 feet.
See your indicator manual to determine the proper load cell cable input connectors. Use the following color codes to wire the load cell cable.

2.3 Grounding the Scale Base

Bench scales can build up a static electricity charge during weighing operations. If powerful enough, this charge can travel through the load cell cable to the indicator. To prevent this, all bench scales should be adequately grounded so that static charges and transient electrical surges can drain directly to ground. Recommended practice is to connect the scale base to an AC ground circuit using at least #12 wire. All BenchMark scales have either a grounding screw or a hole for such a grounding screw located on the bottom of the lower frame for this purpose.
Installation 5

3.0 Calibration

It is recommended that the scale be “exercised” by loading it to near capacity two or three times before calibration to be certain that everything is seated. To calibrate your BenchMark:
1. With no load on scale, place the indicator in its calibration mode and perform a zero calibration.
2. Place test weights on platform equal to 70%–100% of scale’s capacity. If several weights are used, they distribute them evenly around the platform.
3. Perform a span calibration.
4. Remove the test weights and check the zero reading. If necessary, repeat the calibration process.
See the indicator manual for the specific indicator calibration procedure.

5.3 Installing Protective Clamshells

Important
UPPER CLAM SHELL
LOWER CLAM SHELL
Stainless steel enclosures called clamshells are available to provide extra protection for the load cell of every BenchMark scale. All clamshells are pre-drilled for load cell screws, overload screws, and cables. Any existing load cell shims or spacers are installed inside the clamshells.
1. The lower clamshell fits inside the upper cl part of it touches the load cell, then tighten the lower load cell screws to the specifications given Section 5.1 or Section 5.2.
When installing the upper clam shell, position it so there is clearance on all sides to prevent any binding problems with the lower clam shell.
2. Tighten the upper load cell screws to the required torque.
3. When installation is complete
, reset all overload protection screws as described in Section 5.1 or
Section 5.2.
4. Calibrate the scale according to the proce
amshell and is installed first. Position the clamshell so that no

BenchMark Series 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 systems and components are warranted against defects in materials and workmanship for two 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 nonconformity, 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 nonconformity actually exists, and was not caused by accident, misuse, neglect, alteration, improper installation, improper repair or improper testing; RLWS shall be the sole judge of all alleged nonconformities.
• 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 MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER RLWS NOR DISTRIBUTOR WILL, IN ANY EVENT, BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.
RLWS AND BUYER AGREE THAT RLWS’S SOLE AND EXCLUSIVE LIABILITY HEREUNDER IS LIMITED TO REPAIR
OR REPLACEMENT OF SUCH GOODS. IN ACCEPTING THIS WARRANTY, THE BUYER WAIVES ANY AND ALL OTHER CLAIMS TO WARRANTY.
SHOULD THE SELLER BE OTHER THAN RLWS, THE BUYER AGREES TO LOOK ONLY TO THE SELLER FOR
WARRANTY CLAIMS.
No terms, conditions, understanding, or agreements purporting to modify the terms of this warranty shall have any legal effect unless made in writing and signed by a corporate officer of RLWS and the Buyer.
