GOT-2770S User’s Manual
2.2.4 Safety Guidelines
This section presents recommended installation practices, and
procedures. Since no two applications are identical, these
recommendations should be considered as guidelines.
Hardware Considerations WARNING!
The system designer should be aware that devices in Controller
systems could fail and thereby create an unsafe condition.
Furthermore, electrical interference in an operator interface, such as a
GOT-2770S, can lead to equipment start-up, which could result in
property damage and/or physical injury to the equipment operator.
If you, or your company, use any programmable control systems that
require an operator or attendant, you should be aware that this
potential safety hazard exists and take appropriate precautions.
Although the specific design steps depend on your particular
application, the following precautions generally apply to installation of
solid-state programmable control devices. In addition, these
precautions conform to the guidelines for installation of Controllers as
recommended in the NEMA ICS 3-304 Control Standards.
Programming Considerations
To conform with ICS Safety Recommendations, checks should be
placed in the controller to ensure that all writable registers that control
critical parts of plant or machinery have limit checks built into the
program, with an out-of-limit safe shut down procedure to ensure
safety of personnel.
