6 Maintenance and Repairing
Maintenance and repairing must be performed in compliance with all safety instructions in this manual.
Repairing must be performed by an authorized system integrator or JAKA staff. Parts returned to JAKA should
be returned as specified in the Service Manual.
6.1 Safety Instructions
After maintenance and repairing, product must be checked to ensure the required safety level. The valid
national or regional work safety regulations must be observed for this check. The correct functioning of all
safety functions shall also be tested.
The purpose of maintenance and repairing is to ensure that the system is kept operational or, in the event
of a fault, to return the system to an operational state. Repairing includes troubleshooting in addition to the
actual repair itself.
The following safety procedures and warnings must be observed during the operation of the robot or
electrical cabinet:
DANGER:
1. Do not change anything in the safety configuration of the software (e.g.
the force limit). If any safety parameter is changed, the complete robot system
shall be considered as a new system, which means that the overall safety
approval process, including risk assessment, shall be updated accordingly.
2. Replace faulty components using new components with the same
article numbers or equivalent components approved by JAKA for this purpose.
3. Reactivate any deactivated safety measures immediately after the work
is completed.
4. Document all repairs and save this documentation in the technical file
associated with the complete robot system.
DANGER:
1. Remove the main input cable from the bottom of the electrical cabinet
to ensure that it is completely unpowered. Deenergize any other source of
energy connected to the robot arm or control box. Take necessary precautions
to prevent other persons from powering on the system during the repair period.
2. Check the earth connection before re-opening the system.
3. Observe ESD regulations during the disassembly of the parts of the
robot or electrical cabinet.
4. Avoid disassembling the power supply inside the electrical cabinet.
