On-site troubleshooting
A technician on your floor with the meters, software and experience to trace a fault to its source.
Industrial Machine Diagnostics
Industrial machine diagnostics and repair that gets you back online
Downtime is measured in dollars per hour, not days. URang troubleshoots industrial machines on site — from PLC faults and drive failures to wiring, sensors and operator interfaces — and either repairs the problem or tells you exactly what needs to happen next.
What's included
Everything needed to make it work
A complete scope, not a list of billable extras. Here is what this service covers.
PLC diagnostics
Fault code interpretation, I/O forcing, program review and recovery for Allen-Bradley, Siemens and other common platforms.
VFD, servo & motor control
Drive faults, parameter recovery, motor and encoder checks, and replacement sizing when a drive is beyond repair.
HMI & operator interface
Blank screens, communication loss, dead touch panels and replacement or migration options.
Electrical & wiring faults
Power distribution, control circuits, sensors, relays, contactors and intermittent connections.
Documentation & preventive checks
As-built notes and recommended spares so the next fault is faster to resolve.
Problems we solve
The failures we see every week
- Machine down and production stoppedPriority response for down equipment, with clear communication on arrival and expected resolution.
- Intermittent fault nobody can reproduceSystematic testing and logging to catch the condition that triggers the fault.
- Cryptic PLC or drive fault codesWe translate the code, verify the circuit and identify whether it is a device, wiring or program issue.
- Aging equipment with no drawingsWe trace and document the control circuit so future maintenance is not guesswork.
- Failed drive with long lead timeRepair, refurbished replacement or a compatible alternative to bridge the gap.
- Repeat failures after a quick fixRoot-cause repair instead of resetting the fault and waiting for it to happen again.

How it works
What working with us looks like
When a machine goes down, the first job is to protect production. We ask for the fault code, the machine make and model, what changed immediately before the failure and whether the line is fully stopped or running degraded. That information lets us bring the right tools and, often, the right spare on the first trip.
On site, diagnosis follows the circuit rather than the guesswork. We verify power, check safety circuits and interlocks, inspect connections and sensors, read PLC and drive fault history, and test the devices the controller is complaining about. Intermittent faults get special treatment: we log conditions over time rather than declaring the machine fixed because it ran for ten minutes.
Once the cause is known we present the options clearly. Sometimes it is a component replacement; sometimes it is a board repair, a parameter recovery or a wiring correction. If the honest answer is that the machine needs a controls retrofit, we say so and scope it, but we do not use a breakdown as an excuse to sell a rebuild.
The repair is not finished until the machine runs under real load and the maintenance team understands what happened. We leave notes on the fault, the fix and the recommended spares, so the next event — if there is one — is resolved faster and with less production lost.
Why URang
What you get that a generalist cannot offer
Downtime-first mindset
We ask the questions that shorten the repair before we arrive, and we prioritize stopped production over routine work.
Controls and electrical depth
PLC, drive, HMI and wiring experience in one technician means fewer handoffs and less time waiting.
Honest recommendations
If a repair is the right call we repair it. If a retrofit is the right call we scope it. We do not sell around the diagnosis.
Service area
Local response across the Dayton metro
We respond to industrial downtime across Dayton, Kettering, Moraine, Miamisburg, West Carrollton, Vandalia, Troy, Tipp City, Springfield and the surrounding Miami Valley manufacturing corridor. Remote program and drive support is available for clients outside the immediate service area.

Common questions
Industrial Machine Diagnostics — FAQ
How quickly can you respond to a down machine?
Local emergency calls are typically addressed the same day, and often within hours depending on schedule and travel. We ask for the machine make, model and fault code when you call so we arrive prepared.
What brands do you work on?
We work on Allen-Bradley/Rockwell, Siemens, Mitsubishi, Omron, AutomationDirect and many legacy platforms, along with common drive and servo manufacturers. If we do not support a specific platform, we will tell you up front.
Do you carry spare parts?
We carry common components and can source or repair boards and drives quickly. For critical machines we help you build a recommended spares list.
Can you work from our existing drawings?
Yes, and if drawings are missing or wrong we trace the circuit and update them as part of the repair.
Do you offer preventive maintenance?
Yes. Scheduled inspections of controls, drives, cooling and connections catch many failures before they stop production.
What if the machine needs a full controls upgrade?
We scope the retrofit, explain the trade-offs and can carry out the upgrade — but we will not push a replacement when a repair is the right call.
