Installation and Commissioning

Safety8.2 Tools/workpiecesIt must be possible to turn off tools, such as milling cutters, etc., safely. Make sure thatguards remain closed until the cutters stop rotating.Grippers must be designed so that they retain workpieces in the event of a power failureor a disturbance of the controller. It should be possible to release parts by manualoperation (valves).8.3 Pneumatic/hydraulic systemsSpecial safety regulations apply to pneumatic and hydraulic systems.Residual energy may be present in these systems so, after shutdown, particular caremust be taken.The pressure in pneumatic and hydraulic systems must be released before starting torepair 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 preventtools, etc., from falling due to gravity.9 Risks during Operation DisturbancesIf the working process is interrupted, extra care must be taken due to risks other thanthose associated with regular operation. Such an interruption may have to be rectifiedmanually.Remedial action must only ever be carried out by trained personnel who are familiarwith 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 industrialapplications. All work must be carried out professionally and in accordance with applicablesafety regulations. Care must be taken at all times.10 Risks during Installation and ServiceTo prevent injuries and damage during the installation of the robot system, the regulationsapplicable in the country concerned and the instructions of ABB Robotics mustbe 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 safetyfunction are interlocked in accordance with the applicable standards for that function.• The instructions in the Product Manual/Installation must always be followed.• The mains supply to the robot must be connected in such a way that it can be turnedoff outside the robot’s working space.Product Manual 11
