(5) Make sure that the robot manipulator and the wiring and piping of controller,
interlock panel, and timer should not be placed in the way of operator's
working range so that they would not be directly stepped on by FORK and
LIFT. There is a possible danger of accident if the workers are affected by
electricity or the wiring is down.
(6) Place the controller, interlock panel, and handling stand within the sight of
robotic performance. It may cause a serious accident to operate the robot
while the operator is working, or the robot is malfunctioning in an invisible
sight.
(7) Restrict the robot's working envelope by using soft limits and mechanical
stopper if the necessary working envelope is narrower than the holding
workable envelope. It is possible to stop the robot in advance when it moves
beyond its normal working envelope due to an abnormal condition. (Refer to
the 『Robot Manipulator Maintenance Manual』.)
(8) Welding spatters directly on the operator or around him may cause burning or
fire. Install such devices as a glare shield or a cover in the full sight of
robot's working envelope.
(9) Make sure that the device indicating the robot's running condition whether
automatic or manual mode must be noticeable even in the far distance. In the
case of automatic start-up, warning with a buzzer or warning lamp is also
valid.
(10) Make sure that there is no projecting part in the robot's peripheral equipment.
Cover it, if necessary. It usually may cause an accident if the operator comes
in touch with it. And it may lead a serious accident if the operator is
astonished at the sudden movement of robot, and conducts it.
(11) Don't make the system designed to allow the workers to carry the Work in
and out using their hands through the safety fence. It could be a cause of
accident associated with compressing or amputating.
