6. Front Panel & Operation
6.1 Front Panel Layout
LED Indicators
POWER: On = 24 VDC present.

7. Safety Precautions
High Voltage Hazard: Only qualified electricians may install/service; disconnect all power (DC + AC) before wiring.
ESD Risk: Static electricity can damage the PCB; use anti‑static protection.
AC Voltage: Synchronisation terminals carry AC voltage; risk of electric shock.

9. Troubleshooting
| Fault Phenomenon | Possible Cause | Solution |
|---|---|---|
| POWER LED Off | No 24 VDC / blown fuse | Check power wiring; replace 3 A fuse |
| RUN LED Solid (Fault) | Config error / I/O fault / overvoltage | Check LCD alarm; verify config/wiring |
| SYNC LED Not On | Voltage/freq/phase mismatch / wiring fault | Adjust gen voltage/freq; check AC wiring |
| Analogue Input Inaccurate | Config mismatch / noisy signal / sensor fault | Correct AI scaling; use shielded cables |
| Communication Failure | Wrong address / cable fault / termination | Verify Modbus/CAN address; check cable/termination |
| Genset Fails to Start | DI wiring fault / engine fault / config error | Check start DI; verify engine; check start sequence |
