Engineering Support Built Around Generator Uptime
From difficult control faults to synchronization, retrofit, commissioning and periodic maintenance — GCX Power supports the complete generator-control lifecycle.
Focused on the control and electrical layer of generator systems.
Control System Troubleshooting
For generators that fail to start, stop, close the breaker, communicate correctly or operate consistently.
- Controller alarms and configuration
- Digital/analog I/O diagnosis
- Breaker command & feedback logic
- CAN/J1939 and Modbus communication
- Sensors, permissives and interlocks
Synchronization & Load Sharing
Diagnosis and commissioning of generator paralleling and power-sharing functions.
- Voltage/frequency matching
- Phase-angle and sync-check logic
- kW load sharing
- kVAR / power-factor sharing
- Dead-bus and breaker-close logic
Commissioning & Recommissioning
Structured functional testing for new, modified or long-idle generator-control systems.
- I/O and alarm verification
- Start/stop sequence testing
- Breaker and interlock tests
- Synchronization tests
- Load tests and handover documentation
Controller Replacement & Retrofit
Migration planning when a controller is failed, obsolete or no longer supportable.
- Existing-system survey
- Replacement selection
- I/O and wiring mapping
- Configuration / programming
- Installation support and recommissioning
Preventive Maintenance & Health Checks
Periodic engineering inspection focused on controls and power-management readiness.
- Controller backup verification
- Alarm/event review
- Communication health
- Breaker-control tests
- Synchronization & load-sharing checks
ATS / AMF & Breaker Control
Troubleshooting and testing of utility sensing, generator start, transfer and breaker-control sequences.
- Utility fail/return logic
- Generator start permissives
- ATS / AMF sequence
- Interlocks and feedback
- Transfer timing and functional test
PLC / SCADA / PMS Integration
Integration of generator controllers into supervisory automation and power-management systems.
- Modbus RTU/TCP
- PROFINET / industrial Ethernet
- PLC logic integration
- SCADA monitoring and alarms
- PMS sequencing and status
Remote Engineering Support
Pre-site diagnosis and guided troubleshooting where safe remote access and site support are available.
- Alarm/configuration review
- Backup comparison
- Network/communication diagnosis
- Remote engineering guidance
- Pre-commissioning preparation
A generator should be tested before the outage tests it for you.
Periodic control-system maintenance is designed to identify hidden configuration, communication, breaker and synchronization issues before they become emergency call-outs.
Typical control-system health check
- Controller configuration and backup status
- Active and historical alarm review
- I/O status and critical sensor verification
- Battery / DC control supply checks
- Breaker command, feedback and interlock verification
- Network and controller communication status
- Synchronization and load-sharing functional checks
- Service report with findings and recommendations
A simple engineering process from first contact to documented handover.
01 — Assess
Collect controller model, alarms, drawings, operating history and site information before intervention.
02 — Diagnose & Plan
Define the likely failure area, testing approach, required access and any replacement/retrofit scope.
03 — Execute & Test
Troubleshoot, repair/modify where agreed, then functionally test the complete operating sequence.
04 — Document & Handover
Record findings, changes, test results and recommendations so the site is left with a clear technical baseline.
The right information can shorten troubleshooting time.
If available, send the following before a remote review or site visit:
- Controller make, model and part number
- Photo of alarm/event screen
- Generator quantity and operating mode
- Single-line diagram or control drawing
- Description of when the fault started
- Any recent changes, maintenance or controller replacement
- Site location and required response time
A control problem should not become a prolonged outage.
Send the controller model, alarm details and site location. GCX Power will review the issue and define the next engineering step.
