The Joy Of Victorious Troubleshooting

Usually In a manufacturing facility you will find several mechanics and only 1 or 2 electrical people at any given time.
This is because you are dealing with moving equipment, which breaks and wears out frequently.
For the electrical people there are plenty of preventative maintenance tasks and upgrades to do.

However sometimes the equipment refuses to work or does something erratic, and no one knows why. Continue reading “The Joy Of Victorious Troubleshooting”

Concerning Electrical Enclosures

An electrical enclosure is a container for electrical or electronic equipment.
They sometimes are also used to mount knobs, switches, and other user controls plus indicators such as touchscreens, readouts and various other displays.
Their primary function, however, is to protect users from electric shock and protect the internal components from the elements.
Regulations may dictate the features and performance of enclosures for electrical equipment in hazardous areas, such as coal mines, petrochemical plants, and various power distribution facilities. Electronic packaging may place many demands on an enclosure for: Continue reading “Concerning Electrical Enclosures”

A little about PLC’s

It seems to me that most information available on this topic assumes a moderate knowledge level before beginning their discussion, so I intend to break this down a little to accommodate those of you who may not have even heard of PLC’s before today.  Along the way, I will share my perspective as someone who has been working “hands-on” since the late eighties.
The most basic form of PLC’s are hardened, industrialized PC’s which provide inputs and outputs. Continue reading “A little about PLC’s”

About Lockout-Tagout…

Lockout-Tagout is a reference to established safety procedures for use in industrial and research facilities.
Lockout-Tagout was first created and introduced by OSHA in 1982 in response to the high number of workers suffering injury and death in those facilities, OSHA (Occupational Safety And Health Administration) itself is a federal agency of the United States and was established in 1971.
The regulations went into effect in 1989, and are directly responsible for a dramatic decrease in the number of injuries and deaths in the US workplace.
Lockout-Tagout procedures ensure that dangerous machines have been properly shut-down and are not capable of being re-started before the completion of maintenance or servicing work. They require that all hazardous energy sources have been: Continue reading “About Lockout-Tagout…”

About Motor troubleshooting and the use of Meggers…

This particular activity is potentially very dangerous because power needs to be applied and locked out frequently, so please follow proper lockout-tagout procedures!
Meggers are a must in the area of industrial electrical troubleshooting because they can help quickly identify some sources of malfunctions while eliminating other sources as the cause of the malfunction.
As an example, let’s say that a motor refuses to turn. The problem could be coming from let’s say 3 different directions. Continue reading “About Motor troubleshooting and the use of Meggers…”
