1.3. Safety during trouble shooting
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.
Trouble shooting work differs from this. While trouble shooting, 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 trouble shooting
This implies that special considerations unconditionally must be taken when trouble
shooting:
3HAC020738-001 Revision: K
• 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.
