0.4 Hz to 0.8 Hz (used for non-power-state info like communication). Physical Layout:
Control panels on machinery must follow IEC 60073 color assignments to ensure consistent interpretation across international operations. For example, motor starter switches universally use red for STOP (aligning with traffic lights) and green for START or GO.
The standard provides guidelines for assigning meanings to indicators based on the state of the equipment. 1. Visual Coding (Colors and Shapes)
Organizations like ANSI (US), BSI (UK), or DIN (Germany) also provide access to this standard. IEC 60073:2002 iec 60073 pdf
Faulty state or hazardous condition (e.g., toxic leak, extreme overheating).
Since IEC 60073 has been adopted as a national standard in many countries, you can purchase it through:
standard (latest version IEC 60073:2002 ) provides the basic safety principles for human-machine interfaces, specifically the coding of indicators and actuators The standard provides guidelines for assigning meanings to
The most common application is color-coding indicator lamps. According to D G Controls , these are the standard meanings: Safety Meaning Process State Emergency or Fault (e.g., DC supply failure) Abnormal condition; requires attention Normal operation; "Go" status Action required by the operator (e.g., Reset) No specific safety meaning; general status Actuator Guide (Buttons & Switches) For buttons (actuators), the color often dictates the of command you are giving: : Used exclusively for Stop or Emergency Stop functions. : Typically used for Start or "On" functions. Yellow/Amber
In the modern industrial landscape, machine safety and operational efficiency rely heavily on effective communication between machines and operators. The provides the essential framework for this man-machine interface, setting global standards for how visual, acoustic, and tactile indicators should be coded to ensure safety and clarity.
State requires a defined operator action (e.g., pre-start checklist, manual reset). Operator must perform the commanded task before proceeding. IEC 60073:2002 Faulty state or hazardous condition (e
(Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators) is an international standard that defines how to assign specific meanings to signals.
For a simplified breakdown of how these rules apply in real-world hardware, the ABB Pilot Devices Guide provides practical implementation examples . INTERNATIONAL STANDARD IEC 60073
The standard specifies how different sound patterns convey distinct meanings:
