1.7.3. Safety Precautions for Automatic Operation
(1) While posting a sign [Do Not Enter During Operation] up the safety fence gate,
ask the operators not to enter during operation. If the robot stops, you may
enter the safety fence under your full understanding of the situation.
(2) Be sure to check if any operators are inside of the safety fence when starting
the automatic operation. Operating without checking the presence of
operators may cause a personal injury.
(3) Before starting the automatic operation, check and confirm that the program
number, step number, mode, and starting selection are in the possible state
for automatic operation. If starting with the other programs or steps selected,
the robot could move in an unpredicted way, and lead to an accident.
(4) Before starting the automatic operation, check if the robot is properly located
to get started. Check whether the program number or step number is identical
with the location of robot. Even if it's all identical, accidents are still possible to
occur due to an abnormal movement when the robot is differently located..
(5) Be prepared to immediately press the emergency stop button when starting
the automatic operation. Immediately press the emergency stop button in
case of robot's unexpected movements or emergency.
(6) Be sure to detect any abnormalities by checking the route, condition, or
sound of robot movement. Sometimes the robot may be abnormally operated
including a sudden break down. However, it will show(give) a certain
indication before the break down. Understand the robot's normal condition
well in order to catch the symptom in advance.
(7) When any abnormality is detected from the robot, immediately stop and take
proper actions on it. Using the robot before any proper actions taken may
cause an interruption of produce as well as serious failure leading to a very
serious personal injury.
(8) When checking the robot’s movement after the proper actions taken for the
abnormality, do not operate the robot with operators inside of the safety fence.
Unexpected accidents are possibly to occur because its low reliability may
cause another abnormality.
