4.4.1 Safety measures
1. Referring to warning labels and manual
WARNING
• BEFORE STARTING INSTALLATION OR OPERATION OF THE ROBOT, BE SURE TO READ THE WARNING LABELS
AND THIS MANUAL, AND COMPLY WITH THE INSTRUCTIONS.
• NEVER ATTEMPT ANY REPAIR, PARTS REPLACEMENT AND MODIFICATION UNLESS DESCRIBED IN THIS MANUAL.
THESE TASKS REQUIRE SPECIALIZED TECHNICAL KNOWLEDGE AND SKILLS AND MAY ALSO INVOLVE
HAZARDS. PLEASE CONTACT YOUR DISTRIBUTOR FOR ADVICE.
NOTE
For details on warning labels, see "3. Warning labels" in "Safety instructions."
2. Draw up "work instructions" and make the operators/workers understand them
WARNING
DECIDE ON "WORK INSTRUCTIONS" IN CASES WHERE PERSONNEL MUST WORK WITHIN THE ROBOT SAFETY
ENCLOSURE TO PERFORM STARTUP OR MAINTENANCE WORK. MAKE SURE THE WORKERS COMPLETELY
UNDERSTAND THESE "WORK INSTRUCTIONS".
Decide on "work instructions" for the following items in cases where personnel must work within the robot safety enclosure to
perform teaching, maintenance or inspection tasks. Make sure the workers completely understand these "work instructions".
1. Robot operating procedures needed for tasks such as startup procedures and handling switches
2. Robot speeds used during tasks such as teaching
3. Methods for workers to signal each other when two or more workers perform tasks
4. Steps that the worker should take when a problem or emergency occurs
5. Steps to take after the robot has come to a stop when the emergency stop device was triggered, including checks for cancelling
the problem or error state and safety checks in order to restart the robot.
6. In cases other than above, the following actions should be taken as needed to prevent hazardous situations due to sudden or
unexpected robot operation or faulty robot operation as listed below.
• Place a display sign on the operator panel
• Ensure the safety of workers performing tasks within the robot safety enclosure
• Clearly specify position and posture during work
Specify a position and posture where worker can constantly check robot movements and immediately move to avoid
trouble if an error/problem occurs
• Take noise prevention measures
• Use methods for signaling operators of related equipment
• Use methods to decide that an error has occurred and identify the type of error
Implement the "work instructions" according to the type of robot, installation location, and type of work task.
When drawing up the "work instructions", make an effort to include opinions from the workers involved, equipment manufacturer
technicians, and workplace safety consultants, etc.
3. Take safety measures
DANGER
• NEVER ENTER THE ROBOT MOVEMENT RANGE WHILE THE ROBOT IS OPERATING OR THE MAIN POWER IS
TURNED ON. FAILURE TO FOLLOW THIS WARNING MAY CAUSE SERIOUS ACCIDENTS INVOLVING INJURY OR
DEATH. INSTALL A SAFETY ENCLOSURE OR A GATE INTERLOCK WITH AN AREA SENSOR TO KEEP ALL PERSONS
AWAY FROM THE ROBOT MOVEMENT RANGE.
• WHEN IT IS NECESSARY TO OPERATE THE ROBOT WHILE YOU ARE WITHIN THE ROBOT MOVEMENT RANGE
SUCH AS FOR TEACHING OR MAINTENANCE/INSPECTION TASKS, ALWAYS CARRY THE PROGRAMMING BOX
WITH YOU SO THAT YOU CAN IMMEDIATELY STOP THE ROBOT OPERATION IN CASE OF AN ABNORMAL OR
HAZARDOUS CONDITION. INSTALL AN ENABLE DEVICE IN THE EXTERNAL SAFETY CIRCUIT AS NEEDED. ALSO
SET THE ROBOT MOVING SPEED TO 3% OR LESS. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY CAUSE
SERIOUS ACCIDENTS INVOLVING INJURY OR DEATH.
See “7.1 Movement range” in “Safety instructions” for details on the robot’s movement range.
