🔹 Installation & Integration
Before installation, confirm that the existing control system uses the DEIF CRM-1 1044220140E configuration. Check the rack position, terminal connections, system wiring, and associated protection modules.
Current-transformer circuits should be checked carefully for correct phase identification, polarity, and secure connections. Do not alter approved protection settings without confirming the requirements of the vessel’s electrical protection scheme.
After installation, verify module status and communication with the Delomatic controller. Test the applicable protection and alarm functions under an approved commissioning or maintenance procedure before returning the generator or switchboard to normal service.
🔹 Maintenance Recommendations
- Inspect the module housing and front panel for physical damage.
- Check rack connectors for oxidation, contamination, or loose contacts.
- Inspect associated CT wiring and terminal connections.
- Verify that the module is correctly seated in the Delomatic rack.
- Check protection alarms and status indications during scheduled testing.
- Compare current measurements with approved reference values.
- Record existing configuration and protection settings before replacement.
- Keep a compatible spare module available for critical marine automation systems.
