Working Principle The EMP2200 communicates with distributed remote I/O modules to collect analog and discrete sensor data from vessel machinery. The onboard processor compares measured values against preset alarm thresholds. When value exceeds threshold, the module generates timestamped alarm event and sends alarm signal to bridge and engine room HMI consoles. It stores alarm history in flash memory. The watchdog circuit monitors processor operation continuously and triggers system reset if program execution halts. All data is transmitted to upper monitoring network via Ethernet or serial bus.
Installation Requirements
- Install module inside air-conditioned marine control room 19-inch cabinet.
- Use marine-grade shielded cables for all communication wiring.
- Maintain low impedance protective earth connection to ship vessel earth.
- Keep communication cables separated from high power motor and generator cables.
- Configure network address and alarm parameters during vessel commissioning.
- Verify all classification society EMC and vibration requirements are satisfied.
- Test alarm logic simulation before vessel sea trial.
Usage Notes
- Replace RTC backup battery during scheduled ship dry dock maintenance.
- Keep cabinet clean and free from marine salt mist ingress.
- Do not open chassis when vessel critical monitoring system is online.
- Backup alarm configuration and log files periodically.
- Avoid mechanical shock during vessel maintenance and transportation.
- Disconnect power before removing or replacing module.
- Validate alarm function after software parameter modification.
