First-Time Operation Checklist

• 🔍 Wiring Verification | Verify all low-voltage power supply, actuator, magnetic pickup, and remote setpoint wiring against the installation schematic prior to energizing.
• 🔋 Power Supply Check | Confirm that the DC input voltage is stable and within the 18 to 32 VDC range before powering on the system.
• 📡 Communication Port Setup | Configure the user-selectable serial communication ports and network parameters using the setup software.
• ⚙️ Parameter Configuration | Program engine dynamics, PID tuning constants, and Start/Max/Turbo Boost fuel limiter thresholds via the service software.
• 🧪 Dry Run Testing | Perform actuator response and safety trip checks without fuel pressure to ensure proper signal routing and limiter operation.

Routine Maintenance

• 🧹 Enclosure Inspection | Keep the exterior housing clean and ensure internal cabinet ventilation filters are free of dust and debris.
• 🔌 Terminal Tightness | Inspect all screw terminals and ground connections annually for secure fit and absence of oxidation.
• 💾 Backup Program | Export and securely archive the controller configuration file whenever control parameters or fuel limiter values are adjusted.
• 🔄 Diagnostic Review | Periodically check error logs, sensor feedback health, and communication status via the configuration software.

Troubleshooting & Common Issues

• ❓ Controller Fails to Power On | Check incoming DC power fuses, verify input voltage terminals, and ensure correct polarity.
• ❓ Fuel Limiter Restricting Performance | Review Start, Max, and Turbo Boost fuel limiter settings, and verify analog input signals providing boost pressure feedback.
• ❓ Speed Sensor Signal Loss | Inspect magnetic pickup sensor clearance, clear any metallic debris from the probe tip, and check shielded cable grounding.
• ❓ PC Communication Failure | Verify serial cable pinout, check user-configured port settings, and ensure correct protocol selection in the service software.
