• Intelligent Diagnostics: Built-in fault detection with LED status indicators for easy troubleshooting.

6. LED Indicators

• PWR: Green = Power Normal

• RUN: Flashing green = Operating Normally

• FAULT: Red = Hardware/Software Error

• COM: Amber = Network Activity

7. Installation & Maintenance

1. Install into a standard Ovation DCS slot.

2. Connect power and communication cables; ensure proper grounding.

3. For redundancy, install two identical modules in paired slots.

4. Hot swap only when the system is in redundant mode.

5. Keep the module clean and free of dust.

6. Use only Emerson-certified replacement parts.

8. Safety Notes

• For professional installation and operation only.

• Disconnect power before servicing non-redundant modules.

• Follow site safety procedures and ESD precautions.
