I was the shift instrument electrical tech for the paper mill.

I worked on all production equipment and the supplied power for the plant. There was two of us for the entire site per shift. I worked on anything from high voltage gear to low voltage control power, DCS,PLCs,VFDs,Valve control 3-15 psi 4-20ma. The equipment ranged from the early 60s to the latest modern controls.

I am the shift tech at what is one of the largest chemical plants in the world. I am the only tech on shift I work on anything that comes up electrical or instrument at times determination if the problem is mechanical or electrical. I work with a mechanical tech on shift. The plant has various instruments,scales, motor controls, advanced control loops,DCS,PLCs,motor drives AC and DC. The DCSs range from provox to honeywell and emerson. the plc's are mainly Allen Bradley the older are Midcon. The equipment ranges from the early 60's to modern day equipment. My job is to safely keep production moving.

• For the primary end of the steel mill I am the electrical person on shift
• I often use Allen Bradley software to troubleshoot problems as well as to modify logic to keep production running until time permits for repairs
• Also I have extensive knowledge in AC and DC cranes
• In my job I have the responsibility to keep our cranes operating
• These cranes are fed by a 480 volt AC hot rail, then converted to D.C
• By a rectifier bank
• I also open and close the distribution power feeding our LMF and EAF with 34,500 volts
• At times, I assist three mechanical technicians two are in our melt shop and one is at our caster
• Trouble shooting our water cooling system for our furnace's, caster, vacuum tank degasser, and LMF is also part of my duties
• This includes 4-20ma devices that is analog feed back converted to digital for operators on our HMI's for flow and temperature
• Repairing LVDTs, proportional valves, and other control and feedback devices (used in hydraulic controls) are a part of my extensive knowledge and job skills
• So in our operation I use my extensive electrical knowledge, print reading, ability to read ladder, and understanding of PLC's
• This allows for our ability to keep a safe and productive work environment.
