CHAPTER 5 Periodic Inspection
(2) Inspection to be performed with the controller turned on
WARNING
• The robot controller must be installed outside the safeguard enclosure, to
prevent a hazardous situation in which you or anyone enter the safeguard
enclosure to inspect the controller while it is turned on.
• Bodily injury may occur from coming into contact with the fan while it is rotat-
ing.
• When removing the fan cover for inspection, first turn off the controller and
make sure the fan has stopped.
1) Check that no one is inside the safeguard enclosure, and then turn on the
controller.
2) Place a sign indicating the robot is being inspected, to keep others from
operating the controller, programming unit or operation panel.
3) Check the following points from outside the safeguard enclosure.
Checkpoint
• Cooling fan at rear of controller
(3) Adjustment and parts replacement
1) After inspection, if you notice any adjustment or parts replacement is
needed, first turn off the controller and then enter the safeguard enclosure
to perform the necessary work. After adjustment or replacement is fin-
ished, again review the checkpoints outlined in (1) and (2) above.
2) If repair or parts replacement is required for the robot or controller, please
contact your YAMAHA dealer. This work requires specialized technical
knowledge and skill, so do not attempt it by yourself.
• Check if the fan rotates normally.
• Check if objects blocking the fan are located and remove
if any are found.
• Check for abnormal noise from the rotating fan. If
abnormal noise is heard, visually check and remove the
cause. If no cause is found, contact YAMAHA dealer.
• Check for dust on the fan cover. Remove and clean if
necessary.
