Maintenance

System maintenance must be performed by Doosan Robotics or a company designated by Doosan Robotics. Maintenance is intended to keep the system operable or to return the system to an operable state in the event of a problem, and it includes repair work as well as system diagnosis of potential issues.

When maintenance work is completed, risk assessment must be performed to confirm whether the system satisfies required safety levels. Corresponding national and regional regulations must be observed during inspection, and all possibilities related to safety must be tested.

When performing work on the manipulator or controller, the following safety procedures and warnings must be observed.

• Maintain the safety settings of the software during maintenance work.
• If a particular part is defective, replace it with a new identical part or part approved by Doosan Robotics.
• The replaced part must be returned to Doosan Robotics.
• After completing the work, resume the safety function.
• Document the repair history of the robot system and manage related technical documents.
• Disconnect the power cable and make sure other power sources connected to the manipulator or controller do not supply power.
• Do not connect the system to a power source during maintenance.
• Check the ground connection before supplying power to the system.
• When disassembling the manipulator or controller parts, observe ESD regulations.
• Do not disassemble areas that supply power within the controller. Power supply areas may still be charged with high voltage (up to 600V) even after the controller is turned off.
• Take caution to prevent water or dust from entering the system during maintenance.
