Comau Robotics Product Instruction

GENERAL SAFETY REQUIREMENTS
– Even if the Control Unit is not powered (main switch open), there may be
interconnected voltages deriving from connection to peripheral units or external
power sources (e.g. 24 Vdc input/output). Power off the external sources when
operating on involved system parts.
– Removal of panels, protection shields, grids, etc. is only allowed with the main
switch open and padlocked (where provided and necessary).
– Faulty components are to be replaced with others having the same Part No., or
equivalent components defined by COMAU.
– Trouble-shooting and maintenance activities must be carried out, whenever
possible, outside the protected area.
– Trouble-shooting executed on the control is to be carried out, whenever possible
without power supply.
– If necessary, during troubleshooting, intervene with the Control Unit powered; all
the precautions specified by Safety Standards must be observed when operating
in presence of dangerous voltages.
– Trouble-shooting on the Robot is to be carried out with the power supply powered
off (DRIVE OFF).
– At the end of the maintenance and troubleshooting operations, all the deactivated
safety devices must be reset (panels, protection shields, interlocks, etc.).
– Maintenance, repair and trouble-shooting operations must be concluded with the
check of the correct functioning of the Robotic system (Robot and Control Unit) and
all the safety devices, executed from outside the protected area.
– During the software loading phases (for example after replacement of electronic
boards) use only the original software handed over by COMAU. Scrupulously
follow the system software loading procedure described in the specific Instruction
Handbooks; after loading, always run a test cycle, remaining outside the protected
area.
– The disassembly of Robot components (e.g. motors, balancing cylinders, etc.) may
cause uncontrolled movements of the axes in different directions: before starting a
disassembly procedure, refer to the warning plates affixed on the Robot and to the
supplied Instruction Handbooks.
– On Robots equipped with balancing springs, it is forbidden to remove the protection
cover of the springs.
– Where fitted, always restore the protective casing if previously installed.
Decommissioning and Dismantling
– The decommissioning and removal of the Robot and Control System is exclusively
the task of Authorised Personnel.
– Move the Robot in transport position and mount the axes blocking brackets (when
required) referring to the plate affixed to the Robot and to the Instruction
Handbooks of the Robot itself.
– Before proceeding with decommissioning it is mandatory, depending on the type of
Control Unit:
Where required, the replaced safety components must be configured with the same
parameters as those removed.
