Risk Assessment

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 pendant (T1/T2 or MCP). 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.
The E-Stop circuit is Dual Channel (redundant, diverse, and control reliable). The stop
function is classified as NFPA Category 1.
See
for an E-Stop internal circuit diagram.
DANGER:
The Adept-supplied system components
provide a Category 3 E-Stop control system as defined by
EN 954. The robot system must be installed with
user-supplied interlock barriers. The interlocked barrier
must open the E-Stop circuit in the event of personnel
attempting to enter the workcell when Arm Power is
enabled, except for teaching in Manual mode. Failure to
install suitable guarding or interlocks could result in
injury or death.
