7.2 Safety during troubleshooting

7.2 Safety during troubleshooting
General
All normal service work; installation, maintenance and repair work, is usually
performed with all electrical, pneumatic and hydraulic power switched off. All
manipulator movements are usually prevented by mechanical stops etc.
Troubleshooting work differs from this. While troubleshooting, all or any power
may be switched on, the manipulator movement may be controlled manually from
the FlexPendant, by a locally running robot program or by a PLC to which the
system may be connected.
Dangers during troubleshooting
This implies that special considerations unconditionally must be taken when
troubleshooting:
422
• All electrical parts must be considered as live.
• The manipulator must at all times be expected to perform any movement.
• Since safety circuits may be disconnected or strapped to enable normally
prohibited functions, the system must be expected to perform accordingly.
DANGER
Troubleshooting on the controller while powered on must be performed by
personnel trained by ABB or by ABB field engineers.
