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.
