Amatrol’s ET200S Stack Light training system connects to the 890-ET200SF’s Output Module and covers stack light function and operation in relation to safety PLC applications. Stack lights provide long distance indication of a machine or process’ operating state or condition. This visual, and sometimes audio, indicator allows for operators to quickly assess the problem and gives maintenance technicians information regarding the fault type.
The ET200S Stack Light training includes a five segment stack light, a variable volume annunciator with bracket, a connecting cable, student curriculum, and an instructor’s guide. The 89-SLET200’s curriculum covers a variety of important learning topics including: the function of a stack light; Siemens 8WD44 signal column component identification; the function of the controller’s memory clock bits; stack light operation; and controlling a stack light by modifying a PLC program.
What Does a Stack Light Do?
Stack lights are used to indicate the status or condition of a machine or process from a distance. A traditional stack light contains one or more colored lights, or segments, stacked in a column. Each segment is limited to one color. Each light can be on, off, or blink on/off. The color when lit, and whether it blinks, have certain meanings in each installation. Electrical standards provided by IEC and others provide guidelines for the meaning of certain colors in industrial machinery. There are also other guidelines with respect to the safety of persons and the condition of the process. Stack lights can be used for other purposes and custom applications. The colors can have special meaning for those applications.
What is a Smart Stack Light?
A smart stack light can function as several different types of status lights, depending on the need. Each segment can be configured to a desired color and configured to blink. A smart stack light can switch while running between several applications such as:
- Display liquid or material level
- Display different alarms
- Display speed, movement, or other statuses
