Risk Assessment; Emergency Stop - Techman Robot TM5 Series Manual Book

1.7 Risk Assessment

Before using and installing this product, the user must perform the necessary risk assessments based on
the conditions of use. Refer to the regulations specified in the documentation, such as ISO-10218-2,
ISO-12100, and ISO-15066 for details. The purpose of the risk assessment is to predict possible
accidents during the operation, and prevent the occurrence of accidents or reduce the severity of injuries
effectively with appropriate protective measures. Therefore, the scope of the risk assessment must
include any operation of the machine. Once a risk assessment has been conducted, the user may use
the relevant external components (e.g. sensors, emergency stop devices, fencing or other barrier
devices) and configuration of safety-related parameters in the operating system to prevent potential
accidents during operations. External safety-related components should be installed as directed. Refer
to Chapter 2 for the safety settings of the operating system and how other safety components should be
used.
TM Robot expressly indicates that the major significant residual risk below may exist:
1. Excessive rotation of the 6th joint may result in the fingers being caught between the rear-end of the
camera module and the 5th joint module.
2. The palm or fingers may get caught between the end module and the body of the robot during robot
motion or Hand Guide Instruction.
3. Injuries due to collision with the robot.
4. Injuries due to being hit, crushed, or pinched between the robot and a hard surface.
5. Injuries caused by loose screws which are used to fix the robot to the base.
6. TM Robot explicitly states that serious residual risk may exist in the following scenarios: There is a
risk that improper configuration of the collaborative zone or safety space, as well as the running of
incorrect projects, may lead to the robot colliding at full speed with the human body within the
collaborative space.
