Chapter 1 - Safety
1.2
Notes, Cautions, and Warnings
There are four levels of special notation used in this instruction handbook. In descending
order of importance, they are:
WARNING: If the actions indicated in a "WARNING" are not complied
with, injury or major equipment damage could result. A Warning
!
statement will typically describe the potential hazard, its possible effect,
and the measures that must be taken to reduce the hazard.
WARNING: If in a "WARNING" the actions are indicated with a
lightning bolt instead of an exclamation mark, an electrical danger or
shock is possible for personnel working with the system.
CAUTION: If the action specified in the "CAUTION" is not complied
with, damage to your equipment could result.
!
NOTE: A "NOTE" provides supplementary information, emphasizes a
point or procedure, or gives a tip for easier operation.
1.3
Risk Assessment – Category 1 System
Provided that instructed personnel who enter Adept 550 robot work envelope are wearing
protective headgear, eyeglasses, and safety shoes, it is highly unlikely that the Adept 550
Robot could cause permanent injury. Further, due to its small size, light payload capacity,
and limited reach, it is highly likely that such personnel could avoid being hit by the robot
even in a high-acceleration, runaway, failure condition.
In consideration of these factors, prEN1050 specifies use of a Category 1 Control System
per EN954. EN954 defines a Category 1 Control System as one that employs Category B
components designed to withstand environmental influences (such as voltage, current,
temperature, EMI) and that employs well-tried safety principles. The Adept 550 control
system (Control System) described in this Handbook employs hardware components in
its safety system that meet or exceed the requirements of the Machinery and Low Voltage
Directives.
Further, the control system is fully hardened to all EMI influences per the EMC Directive
(See Appendix C) and meets all functional requirements of ISO10218 – Manipulating
Robots Safely. In addition, a "soft" servo mode has been incorporated to limit impact
forces on the Operator and production tooling when the robot is operated in Manual
Mode.
In consideration of the above, the Adept 550 Control System meets or exceeds the
requirements imposed by the EN954-specified Category 1 level of safety, as evidenced by
the Manufacturer's Declaration at the front of this Handbook.
