Moving from industrial electric maintenance to Remote PLC customer support

I currently work as an industrial electrical maintenance technician, mainly doing troubleshooting, preventive/curative maintenance, electrical diagnostics, PLCs, VFDs, motors, etc.

A friend of mine works for another company and they currently have an opening for Remote PLC Customer Support. He recommended me for the position. It's a 3 man team and my friend is one of them.

The pay would be basically the same as what I'm making now, maybe a little bit more after taxes cause of bonuses and stuff.

On paper, the remote PLC support job sounds like a good opportunity: less physical work, potentially better working conditions, and more experience with PLCs and automation. It could also open doors to more specialized automation/engineering roles in the future.

But I'm hesitant because I'm wondering if I'm giving up something valuable by leaving industrial maintenance.

For people who have worked in both areas:

-Is moving from industrial maintenance to remote PLC customer support a good career move?

-Does remote PLC support give you better career progression in automation?

-Is the work actually less stressful?

-Would you take the move if the salary was exactly the same?

-What should I ask the company before accepting?

-Is there anything I might regret after leaving maintenance?

I'm not necessarily looking for a higher salary right now. I'm more interested in which path gives me better opportunities and skills in the long run.

When I was an apprentice

"Finished" can mean wildly different things to people.

One of the maintenance guys made this for the mission, sharp as a witches tit and not painted.

When I was an apprentice, if I left a burr on a piece of metal my boss would get me sweeping the workshop for an hour if I was lucky.

We all think differently, but when something is going to be used for years an extra 30 minutes with a file and a lick of paint goes a long way.

Heat trace

Ive just worked on installing new heat trace circuits on a pipe in our facility. The full run has 4 primary and 4 secondary circuits run along its length. Where they end and the new begin I keep a healthy distance to avoid possible crossings. What does everyone else do for different circuit spacing on their runs? The gap in the picture is about a foot and it is inside a climate controlled building and will have insulation.

I suck at maintenance

So I’ve been a maintenance tech for about 4 years now and I’ve realized I suck at this job. I’m a horrible fabricator, not really the best mechanical person. Only thing I like and decent at is electrical. Obviously I’m in the wrong field so what else could I do? I went to school for industrial electrical maintenance, not sure how that could translate to other jobs.

On The Struggle Bus Disassembling Nord SK63F - 100 L/4

I usually wrench on cars, and figured how bad could it be to replace the output shaft bearing on some farm equipment gearbox. Well it's absolutely terrible and kicking my ass. This bastard weighs over 200lbs. Motor and gearbox clock in at 325lbs. It took a superhuman effort to get the spring coupling sprocket off the output shaft.

I removed the output shaft seals and all the broken bearing pieces. I have the intermediate shaft and gear free, but there isn't room to get the gear out. Can't access the spring clip for the input shaft because the output shaft gear is in the way. I'm trying to remove the output shaft gear, but it's on there with otherworldly forces. I'm not even sure which way to press it off. I can't see a key on either side of the gear, though the exploded view shows it's keyed. All the other gears are keyed.

I haven't been able to locate good resources online. There are men in sandals beating on the output shaft end with 2 hammers. The shaft ends up falling out the bottom. There's also a video of a massive press, installing a shaft on to a gear, pressing from the same output end. Neither example are the same model gearbox.

I bought a 20 ton press, but it gets tight pressing either way. Sucker is on there. I don't think I'm pressing the proper way with the attached picture, but figured I'd try the other way since I wasn't making much progress pressing the other way. 631,632,602,610,642, 650 are out. I don't see a 643 or 649 unless it's blending in to the gear. 650 was a tough circlip to remove. It wouldn't come out with my pliers. I actually broke one of the 7" icon plier tips. The shaft also has a lip and it made grabbing the circlip very difficult. I got it off with a screwdriver and hammer. Also 652/653 and 651 are still on there. The gearbox side of the driveshaft seems like it's wider than those parts and holding them on. The gear side of the driveshaft also tapers down and rides in a roller bearing which is free. Looking for advice. This is eating my lunch.

Gonna get fired

Been working at the same place for nearly 4 years, I like the environment, don't mind the people, live the job. New boss decided to mandate 58 hour weeks with no conversation, no notice, nothing. Supposedly only temporary until the department is making the numbers it's supposed to. Throwing maintenance employees at a production problem as usual. I haven't complied and have been told if I keep it up into next week I'm fired.

Industrial jobs and piercings?

Im started looking at transitioning into an Industrial field but have read mixed things whether piercings are allowed due to safety issues.

What are your all's experience with piercings and the workplace? Im been looking into Industrial Mechanic or Electrican specifically. Are places usually good with no hanging jewelry/non-conductive pieces?

Since it probably matters I'll be working in Germany though Im trying to get a general feel for the industry at this point.

UPS Maintenance Mechanic Test — Failed the Assessment, Retaking in 2 Weeks. What Should I Study?

I recently applied for a Maintenance Mechanic position at UPS and took the assessment/test for the position. Unfortunately, I failed the test.
From what I remember, the test covered a mix of electrical, mechanical, troubleshooting, welding, map reading , cylinders , pumps , etc
related questions. UPS told me I’ll be contacted in about two weeks to retake the test, so I really want to prepare correctly this time. Has anyone here taken the UPS Maintenance Mechanic assessment recently? If so:
What subjects should I focus on?
What type of electrical/mechanical questions were on it?
Is there a specific study guide or practice test?
Any tips for passing the retest? I have electrical/low-voltage experience and some welding experience, but I want to make sure I’m studying the actual material that will be on the test.
Any help would be greatly appreciated.

Transitioning from Conveyor/Sortation Maintenance to Food & Bottling Industry

I’m currently working in conveyor/sortation system maintenance and looking to transition into industrial maintenance in the food or bottling industry. I have hands-on experience with PLCs, hydraulics, pneumatics, sensors, motors, and electrical troubleshooting, but many of the positions I’m seeing prefer candidates with previous food or bottling experience.

For those who have made a similar transition, what skills or equipment should I focus on learning to make myself a stronger candidate? Is there anything specific you wish you had learned before making the switch?

Industrial maintenance tip

I’m a 26 year old industrial maint tech with 6 years experience in the field. One of the little tips I’ve learned that I can share is how to test some electronics with your phone.

I would like to preface this with a bit of information.
Wires create a magnetic field when an amperage is applied to the wire, solenoids seal in unsung magnets, and relays also switch using magnets. The world of magnetic fields is very important in our line of work.

With that said there is an app called “phyphox” which allows you to access raw sensor data from your phone. Using this app you can put your phone on solenoids relays or wires next to your magnetic sensor in your phone. This will tell you if the magnet is engaging in a solenoid or relay, or if you have power going through a wire (troubleshooting fuses, buttons, switches, etc.)

Hopefully this tip can help save you some time or money or just be a cool random piece of information for you all.

Something better then shears for cutting blue filter media

We have to cut up a shit ton of electrical panel intake filters out of rolls of this 1" roll filter media. Supplier wants x2.5 the price to custom cut the rolls in different widths, meaning you still need to cut 1 length by hand.

Besides hand cutting them all with scissors/shears, what do you use to make the job easier/quicker? Do these olfa rotary cutters work well on this filter material?

Is predictive maintenance worth setting up before you have clean machine data?

I work at a local pet food factory and we tried rolling out predictive maintenance on the extrusion line last year, only to spend the first month just realizing how patchy our sensor history actually was. Tags had been renamed twice over the years, a motor got swapped without anyone updating the documentation and nobody could agree on what a normal cycle even looked like anymore. Some teams start with vibration, temperature and current data on a few critical assets and build from there while others spend months cleaning data before touching anything predictive. Im trying to find the middle ground where the setup is useful without turning into its own data cleanup project. How much data quality did you need before predictive maintenance started helping on your line?

Plc question

m currently in school to get my associates this semester im taking plc courses i just completed my apprenticeship and got offered a maint tech pos my question is am I wasting my time with plc from my work exp it seems most plc are proprietary now and have to hook up and let the original writer time to go thru the program. I guess my question is plc becoming a dieing art or is their still a need for it

Correct tension for belt drive after Motor bearing replacement

Heya,

im gonna preface this by saying, yes i used AI to go over my Text to make it make more sense since im not an native english speaker.

I’m trying to properly tension a new timing belt on a machine and would appreciate some help from someone familiar with Optibelt timing belts.

Here is a Link to the Optibelt documentation regarding proper belt tensioning:
https://web.optibelt.com/en/timing-belts-rubber/optibelt-omega-high-power-12644579495483?attribute%5Bprofile%5D=8M&attribute%5Barticle_number%5D=1280+8M+85+HIPO+&attribute%5Bnominal_length_mm%5D=1280
https://a.storyblok.com/f/192292/x/2d92ee5443/optibelt-tm-rubber-timing-belt-drives.pdf
Also a photo of the setup without the belt installed. The measurements shown in the photo are my own approximate measurements.
I’ve also attached a photo of the motor nameplate.

Belt / drive information

  • Belt: Optibelt Omega High Power 8M
  • Belt length: 1280 mm
  • Belt width: 85 mm
  • Motor pulley: 48 teeth, approximately 120 mm diameter
  • Gearbox pulley: 44 teeth, approximately 110 mm diameter
  • Center-to-center distance: approximately 457 mm
  • Motor: 16 kW
  • Gearbox output speed: rated for either 600 or 1200 RPM
  • 3-phase system, located in Germany

The machine is from 1995 and had originally a belt of the same type installed (Contitech HTD 1280 8M), but I had to remove the motor for maintenance. I’ve now bought a new belt and need to get the tension back to the correct value.

Operating conditions

The motor starts via star-delta. It doesn't ramp up particularly slowly — it reaches operating speed in less than a second.

There aren't normally huge shock loads.

Typical current readings are approximately:

Low speed:

  • Idle: ~1.5 A
  • Under load: ~10 A

High speed:

  • Idle: ~3.5 A
  • Under load: ~14 A

When switching from low to high speed, I've seen a brief current spike of up to approximately 40 A, but this only lasts for a fraction of a second.

What I'm trying to determine

Could someone help me calculate the appropriate static belt tension for this setup based on the Optibelt documentation? Im not an engineer, just the owner of my small Stonemasons workshop but trying to do it right. I dont particularly understand some of the Calculations in the Manual, i feel like the diagram does only show half of the things i need to calculate the tension.

More importantly, I don't have the Optibelt tension measuring tool. I'd therefore like a practical way to set the tension using belt deflection with a known applied weight/load. And sanity check with a Sound frequency tester i have from my brothers guitarlessons

Ideally, I'd like to know:

  1. The recommended belt tension in N
  2. What this corresponds to in terms of deflection (mm) at a known applied load, preferably something I can reproduce using kilograms/weights
  3. The expected natural frequency in Hz, so I can tension the belt by deflection and then sanity-check it using a frequency/tension app on my phone

I'm deliberately including as much information as I have, and think would be useful.
If there is additional information needed to calculate this properly, please let me know what measurements/specifications I need to provide.

Thanks in advance!
