Industrial Engineering & Fault-Finding Knowledge Centre
The Wiresight Knowledge Centre provides practical resources for maintenance engineers, engineering managers and manufacturing teams. Guides cover industrial fault finding, maintenance troubleshooting, electrical and PLC troubleshooting, mechanical and conveyor faults, motors, drives, sensors, industrial automation, CMMS, engineering knowledge management and manufacturing maintenance — written for engineers, not as SEO filler.
Browse by category
Electrical
Practical resources for maintenance engineers diagnosing electrical faults — control circuits, motors, drives, sensors and safety circuits. These guides cover structured diagnostic sequences rather than trial-and-error fault finding, and stress safe isolation and competent engineering throughout.
3 articlesPLC
Resources for maintenance engineers working with programmable logic controllers — inputs, outputs, interlocks, permissives, HMI alarms and signal interpretation. Manufacturer-specific procedures and addressing differ, so these guides stay at the engineering-principle level.
2 articlesMechanical
Resources covering mechanical faults that often masquerade as electrical ones — bearings, gearboxes, couplings, belts and loads. Electrical and mechanical causes overlap, so these guides encourage looking across the boundary before concluding.
1 articleConveyors
Resources for diagnosing conveyor faults — from safety circuits and PLC permissives through to drives, motors, belts and mechanical obstructions. Conveyors are common across almost every manufacturing environment, so a repeatable diagnostic structure pays off quickly.
2 articlesMaintenance
Resources on maintenance strategy, diagnostic time, standardising fault finding and preventing repeat failures — aimed at maintenance engineers and team leads who want consistent, repeatable processes rather than heroics.
0 articlesCMMS
Resources explaining what a CMMS does, where it adds value, and how structured fault diagnosis and engineering knowledge complement it rather than replace it.
1 articleEngineering Knowledge
Resources on capturing, standardising and reusing engineering knowledge — so the reasoning behind repairs stays in the business when experienced engineers move on.
1 articleManufacturing
Resources tailored to manufacturing maintenance teams — food, feed, packaging and industrial machinery — where uptime, hygiene, changeovers and multi-site consistency all shape how faults are diagnosed.
