o The battery has exceeded an initial limit, the LD-250 continues to operate but
charging is deferred until the battery has returned to within its temperature
limits.
o The battery has exceeded its temperature limits and the LD-250 will shut
down immediately.
• The LD-250 has an ingress protection rating of IP20 and is not liquid-proof. Keep
floors dry because liquids might get into the AMR. Damp, dusty, or greasy floors
might also cause its drive wheels to slip or skid. Such traction problems can affect
both braking and accuracy.
3.2 Non-intended Use
When deploying an AMR, anticipate potential risks to personnel and equipment. OMRON
intends the LD-250 for use in a carefully controlled and managed environment with
restricted access granted only to trained personnel.
You should conduct a risk analysis before you deploy the LD-250 in other environments. For
example, deployments in areas that are open to general public access such as retail stores.
Application of the LD-250 in such areas generally requires additional safety measures.
OMRON does not intend the LD-250 for deployment in environments that contain:
• Hazardous (explosive or corrosive) atmospheres.
• Ionizing or non-ionizing radiation.
• Extreme heat or humidity.
• Floors that are damp or have any standing water.
IMPORTANT: The LD-250 is not waterproof. Keep all floors dry. Dampness can cause drive
wheels to slip, affecting both braking and navigation.
In addition, OMRON does not intend the LD-250 for deployment in the following
environments:
• Life-support systems.
• Residential installations.
• Mobile installations, including moving floors or any type of land vehicle, watercraft,
or aircraft. (LD-250 navigation is assisted by a gyroscope embedded in the LD-250
Core. For accuracy, the gyroscope requires a stationary environment).
IMPORTANT: Observe all instructions for operation, installation, and maintenance provided
in this guide and in the Mobile Robot LD Safety Guide.
Non-intended use of an LD-250 can:
• Cause injury to personnel.
• Damage the LD-250 or other equipment.
• Reduce reliability and performance.
