24 Adept Cobra PLC600/PLC800 Robot User’s Guide, Rev C
2.3 Precautions and Required Safeguards
This manual must be read by all personnel who install, operate, or maintain Adept
systems, or who work within or near the workcell.
The table below shows the standards that the robot system has been evaluated to meet.
Safety Barriers
Safety barriers must be an integral part of a robot workcell design. Adept systems are
computer-controlled and may activate remote devices under program control at times or
along paths not anticipated by personnel. It is critical that safeguards be in place to
prevent personnel from entering the workcell whenever equipment power is present.
The robot system integrator, or end user, must ensure that adequate safeguards, safety
barriers, light curtains, safety gates, safety floor mats, etc., will be installed. The robot
workcell must be designed according to the applicable local and national standards (see
Section 2.8 on page 32).
The safe distance to the robot depends on the height of the safety fence. The height and
the distance of the safety fence from the robot must ensure that personnel cannot reach the
danger zone of the robot.
The Adept control system has features that aid the user in constructing system safeguards,
including customer emergency stop circuitry and digital input and output lines. The
emergency power-off circuitry is capable of switching external power systems, and can be
interfaced to the appropriate user-supplied safeguards. See Chapter 5 for information on
safe and effective use of the robot.
WARNING: Adept Technology strictly prohibits
installation, commissioning, or operation of an Adept
robot without adequate safeguards according to
applicable local and national standards. Installations in EU
and EEA countries must comply with EN 775/ISO 10218,
especially sections 5,6; EN 292-2; and EN 60204-1,
especially section 13.
