Risk Assessment

Without special safeguards in its control system, the Adept Quattro s650 robot could
inflict serious injury on an operator working within its work envelope. Safety standards in
several countries require appropriate safety equipment to be installed as part of the
system.

Table 2-2

lists some of the safety standards that affect industrial robots. It is not a

complete list. Safeguards must comply with all applicable local and national standards for
the location where the robot is installed.

Exposure

When Arm Power is ON, all personnel must be kept out of the robot work envelope by
interlocked perimeter barriers. The only permitted exception is for teaching the robot in
Manual Mode by a skilled programmer (see

“Qualification of Personnel” on page 32

), who

must wear safety equipment (see

“Safety Equipment for Operators” on page 33

) and carry

the T1 pendant. Therefore, exposure of personnel to hazards related to the robot is limited
(seldom and/or short exposure time).

Severity of Injury

Provided that skilled personnel who enter the robot work envelope are wearing
protective headgear, eyeglasses, and safety shoes, it is likely that any injuries caused by
the robot would be slight (normally reversible).

Avoidance

A programmer must always carry the pendant when inside the work envelope, as the
pendant provides both E-Stop and Enabling switch functions.

For normal operation (AUTO mode), user-supplied interlocked guarding must be installed
to prevent any person entering the workcell while Arm Power is ON.
