5.4 Maintenance and repair
After maintenance and repair work, checks must be carried out to ensure
the required safety level. The valid national or regional work safety regula-
tions must be observed for this check. The correct functioning of all safety
circuits must also be tested.
The purpose of maintenance and repair work is to ensure that the system
is kept operational or, in the event of a fault, to return the system to an
operational state. Repair work includes troubleshooting in addition to the
actual repair itself.
The following safety measures must be carried out when working on the
robot system:
• Carry out work outside the danger zone. If work inside the danger
zone is necessary, the user must define additional safety measures to
ensure the safe protection of personnel.
• The training cell must be switched off, secured to prevent unauthor-
ized persons from switching it on again and disconnected from the
mains power supply.
• The EMERGENCY STOP devices must be actuated and the key for
the EMERGENCY STOP securely stored.
• If it is necessary to carry out work with the robot controller switched
on, the user must define additional safety measures to ensure the
safe protection of personnel.
• If it is necessary to carry out work with the robot controller switched
on, this may only be done in operating mode T1.
• Label the system with a sign indicating that work is in progress. This
sign must remain in place, even during temporary interruptions to the
work.
• The EMERGENCY STOP devices must remain active. If safety func-
tions or safeguards are deactivated during maintenance or repair work,
they must be reactivated immediately after the work is completed.
Faulty components must be replaced using new components with the
same article numbers or equivalent components approved by KUKA
Deutschland GmbH for this purpose.
Cleaning and preventive maintenance work is to be carried out in accord-
ance with the operating instructions.
Robot controller
Even when the robot controller is switched off, parts connected to periph-
eral devices may still carry voltage. The external power sources must
therefore be switched off if work is to be carried out on the robot control-
ler.
The ESD regulations must be adhered to when working on components in
the robot controller.
Water and dust must be prevented from entering the robot controller.
5.5 Decommissioning, storage and disposal
The training cell must be decommissioned, stored and disposed of in ac-
cordance with the applicable national laws, regulations and standards.
