When a machine keeps stopping and nobody is sure whether the fault is electrical or mechanical, Harvtec investigates the system as a whole. We support industrial fault finding across Cornwall, following symptoms through controls, supplies, motors and the equipment they drive.
What Harvtec covers
Industrial sander investigation and Siemens LOGO controls work are existing Harvtec examples. That practical experience helps frame the investigation, while each machine needs its own evidence and safe access arrangements.
A machine may run for hours before stopping, fail at one stage of a cycle or behave differently after a restart.
A trip does not automatically mean the drive needs replacing. Supply conditions, motor behaviour and the driven equipment can all matter.
We review available drawings, software access, previous repairs and the condition of the machine before agreeing what can be investigated.
Explain the evidence and agree the repair, checks and remaining uncertainties with the responsible person.
Practical work
An approved existing work summary; no repair-time or downtime-saving claim is made.
How the work moves
Send the machine/controller/drive make and model, fault messages, frequency, load or cycle stage, and changes made before the problem began.
Plan safe access and isolation, review the available history and test the relevant parts of the system. An intermittent fault may need observations over time.
Explain confirmed findings and what remains uncertain. Agree work and post-repair checks, then retain useful notes for the next engineer or maintenance review.
Check the guidance
Suitable work and inspection arrangements depend on the premises, equipment, process and current requirements. These sources support the information on this page.
Questions
Send the original symptoms, replacement details and any changes in behaviour. That history helps distinguish the original fault from later settings or wiring changes.
Send the machine, controller and drive details first. We can discuss the electrical/mechanical investigation, while proprietary CNC software, parameters and manufacturer access may need separate specialist arrangements.
No. We agree the investigation and explain its limits. Some faults require operating history, repeat observations or further access before a cause can be established.
