Chapter 2: Operational Safety Qualification of Personnel This guide assumes that all personnel have attended an OMRON training course and have a working knowledge of the system. The user must provide the necessary additional training for all personnel who will be working with the system. As noted in this guide, certain procedures should be performed only by skilled or instructed persons. For a description of the levels of qualification, we use the standard terms:
l Skilled persons have technical knowledge or sufficient experience to enable them to avoid the dangers, electrical and/or mechanical l Instructed persons are adequately advised or supervised by skilled persons to enable them to avoid the dangers, electrical and/or mechanical All personnel must observe industry-prescribed safety practices during the installation, oper- ation, and testing of all electrically-powered equipment. To avoid injury or damage to equip- ment, always remove power by disconnecting the AC power from the source before attempting any repair or upgrade activity.
Use appropriate lockout procedures to reduce the risk of power being restored by another person while you are working on the system. ! WARNING: PERSONAL INJURY OR PROPERTY DAMAGE RISK. Before working with the robot, every entrusted person must confirm that they: l Have received the guides (both this guide, and the robot user’s guide) l Have read the guides l Understand the guides l Will work in the manner specified by the guides Protection Against Unauthorized Operation The system must be protected against unauthorized use. The user or operator must restrict access to the keyboard and the pendant by locking them in a cabinet or using another adequate method.
2.10 Sound Emissions The sound emission level of the OMRON robots depends on the speed and payload. The max- imum value is 90 dB. (This is at maximum AUTO-mode speed.) ! WARNING: HEARING DAMAGE RISK. Acoustic emission from these robots may be up to 90 dB (A) under worst-case conditions. Typical values will be lower, depending on payload, speed, accel- eration, and mounting. Appropriate safety measures should be taken, such as ear protection and display of a warning sign. 2.11 Thermal Hazard The following warning applies to both the base and joints for SCARA robots. It applies to the base for parallel robots, and all joints for articulated robots. 18304-000 Rev. F Robot Safety Guide 21
