What we diagnose
Two decades diagnosing the faults that stop facilities from running:
-
PLC faults — programmable logic controller diagnostics, I/O troubleshooting, ladder logic faults and integration issues.
-
VSD and drive faults — variable speed drive tripping, fault codes, motor control diagnostics, speed and torque inconsistencies.
-
Switchboard faults — overheating, arcing, breaker tripping patterns, protection relay misoperation.
-
Three-phase imbalance and power quality — voltage drop, harmonics, neutral loading, phase loss diagnosis.
-
Recurring trip diagnostics — RCDs, circuit breakers and MCBs that won't stay reset.
-
Motor and control circuit faults — contactors, overloads, control wiring and interlocks.
-
Lighting and emergency system faults — emergency lighting failures, sensor and timer faults, control gear issues.
-
Earth fault and insulation breakdown — earth fault loop testing, insulation resistance testing, cable fault localisation.
Why our diagnostics get to the truth
Two decades on industrial sites
20+ years across industrial, manufacturing, cold storage and commercial facilities. We've seen most failure patterns more than once.
Test equipment, not guesswork
Thermal imaging, power quality loggers, insulation testers, oscilloscopes and PLC programming software — the right tool for the actual fault, not parts-swapping on your dime.
Root cause documented
You get a written diagnostic report explaining what failed, why, and what should be done to prevent recurrence. Useful for asset records, insurance and future maintenance scopes.
How a diagnostic call-out works
1. Initial brief
Tell us what's happening — what's failing, how often, when it started. We use that to bring the right test equipment to site the first time.
2. On-site diagnostics
Systematic isolation and testing using instruments rather than parts-swapping. We work through the fault tree until we find the root cause, not just a symptom that responds to a reset.
3. Repair, report and recommendations
Where we can fix on the spot, we do. Where parts or planned downtime are required, we scope and quote. Either way, you get a written diagnostic report with findings, action taken and any recommended follow-up.
