1.0 Introduction
This manual discusses several aspects about the RL101 below-the-hook scale (RL101 scale), including: configuration menu,
parameters, wiring diagrams and errors messages.
Manuals are available from Rice Lake Weighing Systems at www.ricelake.com/manuals
Warranty information is available at www.ricelake.com/warranties
1.1 Safety
Safety Definitions:
DANGER: Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. Includes
hazards that are exposed when guards are removed.
WARNING: Indicates a potentially hazardous situation that, if not avoided, could result in serious injury or death. Includes
hazards that are exposed when guards are removed.
CAUTION: Indicates a potentially hazardous situation that, if not avoided, could result in minor or moderate injury.
IMPORTANT: Indicates information about procedures that, if not observed, could result in damage to equipment or
corruption to and loss of data.
General Safety
Do not operate or work on this equipment unless this manual has been read and all instructions are understood.
Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Rice Lake
Weighing Systems dealer for replacement manuals.
WARNING
Failure to heed could result in serious injury or death.
Read this manual carefully before carrying out any handling operations or lifting any loads.
Never exceed the rated load limit of the unit.
Never use the scale in environments where there is the danger of fire or explosion.
Do not make alterations or modifications to the unit.
Never use the RL101 scale when it no longer fulfills the safety criteria.
Never clean the RL101 scale with solvents, aggressive substances or flammable products.
Never wash the suspended RL101 scale with direct water jets.
Never pour liquids on the RL101 scale.
Do not expose the suspended RL101 scale to atmospheric agents (sun, rain, etc.).
Do not allow minors (children) or inexperienced persons to operate this unit.
Do not use for purposes other than weight measurement.
Do not place fingers into slots or possible pinch points.
Do not use any load-bearing component that is worn beyond 5% of the original dimension.
Do not use this product if any of the components are cracked.
Do not remove or obscure warning labels.
Do not remove or replace supplied shackles and hooks.
Keep hands, feet and loose clothing away from moving parts.
To achieve a correct weighing result, the load must be raised by at least 2-5 in from the ground.
Before using the RL101 scale, ensure it is in proper working order.
Apply the load to the hook only when the load is resting on the ground.
Use the RL101 scale in non-condensing environments with moderate temperature and humidity levels.
Use the RL101 scale where there are no vibrations.
Never move the sample (load) with scale inline. The RL101 scale is a lift and weigh device designed to capture static weighments.

2.5 Weighing filters ()
Edits scale reactivity. “0” represents a minor filtering occurrence. Increasing
the occurrence rate provides more weight stability.
Weigh several times, changing the occurrence rate until the best compromise,
between reactivity and stability is obtained.
NOTE: Filters provide functionality for a variety of applications, however
RL101 applications utilize the Overhead Weighing filter (Section 2.5.1).
