3.3 Control devices
outside the robot's
restricted space
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.
3.4 Positioning of gauges
Pressure gauges, oil pressure gauges and other gauges should
be installed in an easy-to-check location.
3.5 Protection of electrical
wiring and
hydraulic/pneumatic
piping
If there is any possibility of the electrical wiring or
hydraulic/pneumatic piping being damaged, protect them with a
cover or similar item.
3.6 Grounding resistance
The protective grounding resistance of the robot power supply
should not be more than 100Ω.
3.7 Positioning of
emergency stop
switches
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.
3.8 Positioning of
operating status
indicators
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.
