Fault Finding
Industrial Automation Fault Finding in Sydney
CIC helps Sydney and NSW sites chase down stubborn automation faults, intermittents, and post-commissioning issues — across PLCs, drives, instruments and field wiring.
What automation fault finding is
When a machine stops and the cause is not obvious, automation fault finding is the methodical hunt for why. CIC traces the problem from the symptom back through the signal path — alarms, HMI, PLC inputs and outputs, drives, interlocks, sensors and field wiring — to find the actual root cause rather than swapping parts and hoping.
We are most useful on the faults that survive a reboot: intermittents, problems that appeared after a modification or shutdown, and breakdowns where the maintenance team has run out of obvious leads. Where it is urgent, contact us to discuss availability — we confirm honestly what we can get to and when.
What we cover
- PLC, drive and HMI fault investigation
- Intermittent faults that survive a reboot
- Field device, sensor and wiring faults
- Post-modification or post-shutdown issues
- Root-cause notes you can hand back to your team
Where automation faults hide
- PLC inputs and outputs that do not match the field
- Sensors, proximity switches and instruments reading wrong or intermittently
- VSDs and drives faulting, tripping or derating
- Safety interlocks, e-stops and guarding circuits stopping the machine
- Alarms and HMI messages that point in the wrong direction
- Field wiring, connectors and terminations affected by vibration or moisture
Who this is for
- Maintenance teams stuck on a stubborn fault
- Sites recovering after a shutdown
- Contractors needing a second pair of eyes
- OEMs supporting commissioned plants from afar
Typical fault finding call-outs
- A line down with no clear cause and production waiting
- An intermittent fault that will not reproduce on demand
- A machine that started misbehaving after a recent change or shutdown
- A drive or PLC fault the team cannot get to the bottom of
- A second set of eyes needed before parts get ordered
How CIC approaches this work
Methodical
We work from the symptom back through the signal path, not guesses and parts swapping.
Across the stack
Comfortable from field wiring through drives and PLC code up to the HMI and SCADA layer.
Documented
We hand back a short note on what was wrong and what we did, so the next person isn't in the dark.
