This Auxiliary Equipment M-Box is commonly used for compressors, pumps and other equipment for which it is important to know the on/off status and (optional) the electricity consumption.
Alternative sensors may be used and auto-notifications can be set in a flexible way.
This Box reports which equipment is running to help diagnose problems and increase efficiency.
For example, a compressor running (and consuming electricity) when factory is off-work can indicate leaks in the compressed air system.
