3.4.1.4 Qualification of Personnel
You must make sure that all personnel who work with or around AMRs have appropriate
training and have a thorough working knowledge. Provide the necessary additional training
for all personnel that work with the system.
As described in this guide, and the Mobile Robot LD Safety Guide, you should allow only
skilled persons or instructed persons to do certain procedures:
• Skilled persons have technical knowledge or sufficient experience to enable
them to avoid either electrical or mechanical dangers.
• Instructed persons are adequately advised or supervised by skilled persons to
enable them to avoid either electrical or mechanical dangers.
For example, replacing a battery is a task for a skilled person, while an instructed person can
complete the task of charging a battery. All personnel must observe industry-prescribed
safety practices during the installation, operation, and testing of all electrically-powered
equipment.
IMPORTANT: Before working with the AMR, every person must confirm that they:
• Have the necessary qualifications and training.
• Have received the manuals (both the robot user’s manual, and the Mobile Robot LD
Safety Guide).
• Have read the manuals.
• Understand the manuals.
• Will work in the manner specified by the manuals.
3.4.1.5 Payload Movement and Transfer
A typical AMR application uses a payload structure to transport objects within a facility. For
example, the AMR might pick up and carry a crate of engine parts from one conveyor belt
then deliver it to another conveyor belt.
During movement and transfer, you must actively monitor and confirm the transfer
operation to make sure that it completes successfully. If any operation fails, a fail-safe
interlock must trigger an AMR E-Stop condition. An E-Stop condition prevents the AMR from
moving until you resolve the problem and confirm that it is safe to restart operations.
Your facility should provide such fail-safe interlocks between the AMR and any facility
equipment with which it interfaces. After you attach your payload to the AMR, verify the
correct operation of the fail-safe interlock as part of your risk assessment.
3.4.1.6 Configurable Warning Buzzer
The LD-250 has a configurable warning buzzer. Configure this buzzer as appropriate for the
facility in which the AMR operates. By default, the buzzer sounds when the AMR is moving
in any direction other than forward motion.
