1.1 OPERATOR SAFETY
Operator safety is the primary safety consideration. Because it is
very dangerous to enter the operating space of the robot during
automatic operation, adequate safety precautions must be observed.
The following lists the general safety precautions. Careful
consideration must be made to ensure operator safety.
(1) Have the robot system operators attend the training courses held
by FANUC.
FANUC provides various training courses. Contact our sales office for
details.
(2) Even when the robot is stationary, it is possible that the robot is
still ready to move state and is waiting for a signal. In this state,
the robot is regarded as still in motion. To ensure operator
safety, provide the system with an alarm to indicate visually or
aurally that the robot is in motion.
(3) Install a safety fence with a gate so that no operator can enter the
work area without passing through the gate. Equip the gate
with an interlock that stops the robot when the gate is opened.
The controller is designed to receive this interlock signal. When the gate is
opened and this signal received, the controller stops the robot in an
emergency. For connection, see Fig.1.1.
(4) Provide the peripheral devices with appropriate grounding (Class
1, Class 2, or Class 3).
(5) Try to install the peripheral devices outside the work area.
(6) Draw an outline on the floor, clearly indicating the range of the
robot motion, including the tools such as a hand.
(7) Install a mat switch or photoelectric switch on the floor with an
interlock to a visual or aural alarm that stops the robot when an
operator enters the work area.
(8) If necessary, install a safety lock so that no one except the
operator in charge can turn on the power of the robot.
The circuit breaker installed in the controller is designed to disable anyone
from turning it on when it is locked with a padlock.
