Fault Detection and Diagnostics: how data analysis and automatic alarms can assist you and prevent faults

As we saw in the previous article, collecting and analysing consumption data for a site can lead to identifying reasons for waste and by optimising resources it can have a big impact and reduce costs.

It is also possible to connect to a Building Management System (BMS) to obtain consumption data in real time and in quite precise detail, as well as receive all the data relating to the individual devices used, such as Air Handling Units (AHUs). 

In situations like this the BMS can provide the individual variables involved in their operation, such as fan speed, fuel consumption, external temperature detection, valve openings and so on.

Based on the combination of this data it is possible to set up a fault detection and diagnostic system, which can be hugely beneficial, not just in reducing wastage but also in highlighting mechanical issues before they become problematic.

A fault detection and diagnostic system, such as Watts-ON, allows, through a series of automatic algorithms, to identify malfunctions of individual devices within a site, simply by analysing and correlating the data received with each other.

The system then automatically analyses the variables involved in real time and can identify whether the individual device is working efficiently based on the typical behaviour of the equipment.

For example, it is possible to understand whether a cooling or heating system is working efficiently by correlating its switching status with the external temperature.

It is possible to analyse the data and identify malfunctions in the event that the behaviour of the device deviates from the ideal trend of the device itself.

Watts-ON implements a fault detection and diagnostic system and provides diagnostic reports to analyse the situation in real time and a system of automatic periodic notifications that highlight efficiency problems. 

Furthermore, it also has a real-time alarm system sending alerts in the event that the devices are prone to failure.

The advantages of a system of this type are not only in identifying potential faults, but also in correcting settings on the BMS quickly.

It is possible to optimise resources and have savings almost immediately, for zero cost, by diagnosing the behaviour of the BMS and making appropriate modifications.

Watts-ON Consultants are ideally placed to consult, guide and execute a plan and provide accurate reporting so as to make a positive contribution to the future of your business.
