Automated production processes are implemented in almost every factory environment operating today. Good LED indication practices should alert, inform and guide the operator. With the ever-growing number of automated processes and machines, keeping consistent signaling can become quite a challenge but must be implemented for the following reasons:

• The first generation of automation workers is retiring and work forces are shrinking. Those leaving the workforce are taking with them important knowledge of machine operation and in their place is a less experienced team.
• With the reduced process knowledge, having as much consistency in your signaling as possible will help lower the learning curve and result in better performance with predictable volumes of quality product.
• Lost and misplaced hard copy documentation during a crisis can result in increased downtime as the operator may be unaware there is a problem or unsure how to resolve it. With consistent signaling the operator will come to recognize warning signs that can be addressed before the process is halted.
• Standard signaling for common alarms allows the operator to quickly deduce the cause of a machine failure and either fixes the failure or calls maintenance with a clearer diagnosis of the problem.

When engineering your production floor layout, taking into account the basic signals that can be grouped and displayed in a consistent manner is essential for optimizing efficiency and quality. For alarm signaling the recently released ISA/ANSI 18.02 Alarm Management for the Process Industries provides excellent guidelines for indicating and prioritizing alarms. Having indicators on machinery or in stack lights for warnings or caution conditions should be standard as well. Addressing an upcoming error will be simpler and less expensive than the downtime once failure is realized. Implementing standards for your automated indicators and processes will improve your production floor in the following ways:

• Operators will learn your system quicker and be better able to respond when unexpected actions occur.
• There will be a greater tuning of your processes that will allow more consistent forecasting of product.
• You will achieve better diagnostic and more reliable data from your workers as they will better understand the systems.
