Tools/Workpieces; Pneumatic/Hydraulic Systems; Risks During Operation Disturbances; Risks During Installation And Service - ABB IRB 6400R Product On-Line Manual

8.2 Tools/workpieces

It must be possible to turn off tools, such as milling cutters, etc., safely. Make sure that
guards remain closed until the cutters stop rotating.
Grippers must be designed so that they retain workpieces in the event of a power fail-
ure or a disturbance of the controller. It should be possible to release parts by manual
operation (valves).

8.3 Pneumatic/hydraulic systems

Special safety regulations apply to pneumatic and hydraulic systems.
Residual energy may be present in these systems so, after shutdown, particular care
must be taken.
The pressure in pneumatic and hydraulic systems must be released before starting to
repair them. Gravity may cause any parts or objects held by these systems to drop.
Dump valves should be used in case of emergency. Shot bolts should be used to prevent
tools, etc., from falling due to gravity.

9 Risks during Operation Disturbances

If the working process is interrupted, extra care must be taken due to risks other than
those associated with regular operation. Such an interruption may have to be rectified
manually.
Remedial action must only ever be carried out by trained personnel who are familiar
with the entire installation as well as the special risks associated with its different parts.
The industrial robot is a flexible tool which can be used in many different industrial
applications. All work must be carried out professionally and in accordance with appli-
cable safety regulations. Care must be taken at all times.

10 Risks during Installation and Service

Never use the robot as a ladder, i.e. do not climb on the robot motors or other
parts during service work. There is a serious risk of slipping because of the high
temperature of the motors or oil spills that can occur on the robot.
To prevent injuries and damage during the installation of the robot system, the regula-
tions applicable in the country concerned and the instructions of ABB Robotics must
be complied with. Special attention must be paid to the following points:
• The supplier of the complete system must ensure that all circuits used in the safety
