Adept Cobra PLC600/PLC800 Robot User’s Guide, Rev C 33
2.10 Thermal Hazard
2.11 Working Areas
Adept robots have a Manual and an Automatic (AUTO) operating mode. While in
Automatic mode, personnel are not allowed in the workcell.
In Manual Mode, operators with additional safety equipment (see Section 2.13 on page
34) are allowed to work in the robot workcell. For safety reasons the operator should,
whenever possible, stay outside of the robot work envelope to prevent injury. The
maximum speed and power of the robot is reduced but it could still cause injury to the
operator.
Before performing maintenance in the working envelope of the robot, High Power (robot
power) must be switched off and the power supply of the robot must be disconnected.
After these precautions, a skilled person is allowed to maintain the robot. See Section 2.12
for the specifications.
2.12 Qualification of Personnel
This manual assumes that all personnel have attended an Adept training course and have
a working knowledge of the system. The user must provide the necessary additional
training for all personnel who will be working with the system.
As noted in this user’s guide, certain procedures should be performed only by skilled or
instructed persons. For a description of the level of qualification, Adept uses the standard
terms:
• Skilled persons have technical knowledge or sufficient experience to enable them
to avoid the dangers, electrical and/or mechanical.
• Instructed persons are adequately advised or supervised by skilled persons to
enable them to avoid the dangers, electrical and/or mechanical.
WARNING: You can burn yourself. Do not touch the robot
base or outer link shortly after the robot has been running
at high ambient temperatures (40-50°C) (104-122°F) or at
fast cycle times (over 60 cycles per minute). The robot
skin/surface temperature can exceed 85°C (185°F).
WARNING: Never remove any safeguarding and never
make changes in the system that will decommission a
safeguard.
