An essential design principle highlighted in IEC 60073 is that This accommodates color-blind operators and accounts for poor lighting conditions where colors might be distorted. 1. Shape and Position Coding

It is the definitive reference for IEC 60204-1 (Safety of machinery) and other safety standards.

Tactile coding ensures that operators can identify controls by feel, which is crucial in low-light environments or during high-stress emergency situations. iec 60073 pdf

In industrial automation and electrical engineering, clarity saves lives. The international standard establishes a unified framework for the colors and alternative codings used on indicator lights, pushbuttons, and other human-machine interface (HMI) components.

To assist color-blind individuals, it recommends placing Red at the top, Amber in the middle, and Green at the bottom.

Color is the most critical element of visual coding. IEC 60073 assigns specific, non-negotiable meanings to colors used on indicator lights and actuators (push-buttons). Meaning for Indicator Lights Meaning for Actuators (Buttons) Danger / Emergency Act to respond to danger (Stop) Emergency stop, fire alarm Yellow Abnormal / Warning Act to suppress abnormality Overload warning, reset Green Safe / Normal Act to initiate safe conditions Start machine, normal flow Blue Mandatory action Act requiring mandatory intervention Fill fluid, check gauge White/Gray Neutral / No specific meaning General initiate/stop functions General power on, cycle start 2. Acoustic Coding (Sounds) Tactile coding ensures that operators can identify controls

Color is the most effective means of attracting attention, but it must be used strictly according to the defined meanings: Safety Meaning Condition of Process/Equipment Emergency or Fault (e.g., E-Stop activated) Yellow Abnormal condition or transition state Green Normal condition; "Go" or circuit healthy Blue Requires specific operator action White No specific safety meaning; often used for auxiliary states
