Troubleshooting the SmartGrid™ Control Suite requires both a structured process and awareness of the specific context in which the system operates. The following approach ensures consistency, reduces downtime, and prevents incorrect assumptions.
Troubleshooting Workflow
A disciplined sequence of steps is critical when diagnosing issues:
Identify the Symptom
Gather initial reports from operators or alarms shown on the HMI.
Record error codes, alarm IDs, and timestamps.
Confirm whether the issue is localized (single controller) or systemic.
Gather Evidence
Retrieve recent log files from /var/log/smartgrid/.
Capture screenshots or SCADA data trends leading up to the fault.
Perform a visual inspection for hardware indicators such as LED codes, tripped breakers, or burnt fuses.
Verify System State
Ensure controllers have stable DC supply voltage.
Confirm network connectivity between PCUs and SCADA.
Check safety interlocks and emergency stops are not engaged.
Isolate the Cause
Compare behavior with a known-good reference site if available.
Disable non-essential modules to reduce system complexity.
Swap suspected faulty modules with spare parts to confirm the issue.
Apply Corrective Action
Follow the specific resolution steps outlined in the “Common Issues” section of this guide.
Document every action taken to maintain traceability.
Confirm Recovery
Verify normal operation resumes across all modules.
Re-check safety and compliance states.
Monitor the system for at least one operational cycle before declaring the issue resolved.
Best Practices
Change one variable at a time: Avoid simultaneous modifications that complicate diagnosis.
Use approved tools: Non-certified diagnostic software or cabling may yield false results.
Record environmental conditions: Temperature, humidity, and dust can impact performance in industrial settings.
Collaborate with operations staff: Operators often observe subtle patterns not visible in logs.
Maintain a central troubleshooting logbook that includes operator observations, error codes, corrective actions, and results. This historical data is invaluable for both internal learning and vendor escalation.
