1.7 Troubleshooting
General
When troubleshooting requires work with power switched on, special considerations
must be taken:
• Safety circuits might be muted or disconnected.
• Electrical parts must be considered as live.
• The manipulator can move unexpectedly at any time.
DANGER
Troubleshooting on the controller while powered on must be performed by
personnel trained by ABB or by ABB field engineers.
A risk assessment must be done to address both robot and robot system specific
hazards.
WARNING
Never stay beneath a robot arm. Gravity and the release of braking devices can
create additional hazards.
A robot may perform unexpected limited movement.
WARNING
Manipulator movements can cause serious injuries on users and may damage
equipment.
