indicators
The robot controller, teach pendant and mini-pendant should be
installed outside the robot's restricted space and in a place where
you can observe all of the robot's movements and operate the
robot easily.
Pressure gauges, oil pressure gauges and other gauges should
be installed in an easy-to-check location.
If there is any possibility of the electrical wiring or
hydraulic/pneumatic piping being damaged, protect them with a
cover or similar item.
The grounding resistance of the robot power supply should not
be more than 100Ω.
Emergency stop switches should be provided in a position where
they can be reached easily should it be necessary to stop the
robot immediately.
(1) The emergency stop switches should be red.
(2) Emergency stop switches should be designed so that they
will not be released after pressed, automatically or
mistakenly by any other person.
(3) Emergency stop switches should be separate from the
power switch.
Operating status indicators should be positioned in such a way
where workers can easily see whether the robot is on a
temporary halt or on an emergency or abnormal stop.
Note: The UL-Listed robot units have motor ON lamps on their
robot arms.
