Description
📝 Product Overview
The Kongsberg Norcontrol ETU 001 Engine Telegraph Unit is a highly reliable marine navigation and command transmission device utilized for traditional propulsion signaling between the bridge and the Engine Control Room (ECR). Serving as a critical interface in the AutoChief propulsion automation family, it provides failsafe backup and emergency command synchronization, ensuring clear, immediate emergency order communication even during primary automation or workstation blackouts.
⚙️ Technical Specifications
- 📐 Dimensions: 192 mm x 144 mm x 88 mm
- ⚖️ Weight: 1.65 kg
- 🌍 Country of Origin: Norway
🚢 Applications
- Bridge-to-ECR primary and emergency order transmission networks
- Kongsberg AutoChief propulsion command infrastructure
- Failsafe auxiliary telegraph signaling arrays
- Back-up marine speed and direction command logging
🛠️ Usage Instructions
- To execute a command change, move the physical lever or press the designated tactile button corresponding to the desired speed profile (e.g., Full Ahead, Dead Slow Astern).
- Verify that the local acoustic buzzer sounds until the receiving station acknowledges the command by matching their corresponding telegraph interface.
- Check screen backlighting and status indicator LEDs daily during pre-departure watchkeeping checks.
- Avoid exposing the internal non-sealed membrane elements to direct moisture during bridge console cleaning routines.
🔧 Mechanical Installation Requirements
- Fixing Method: Optimized for flush console mounting using integrated rear-clamp brackets, or mounted in a dedicated bulkhead enclosure for engine side open spaces.
- Space Clearance: Maintain a minimum rear-panel clearance boundary of 75 mm to permit proper interface cable bending and to avoid connector tension.
- Heat Dissipation: Passive airflow configuration. Ensure console ambient internal temperatures remain between -15°C and +55°C.
🔌 Electrical Wiring Guide
- Terminal Definitions: * Terminals 1–2: Main 24V DC System Power Input (+ / -)
- Terminals 3–4: Backup 24V DC Battery Input (+ / -)
- Terminals 5–10: Dual RS-485 Serial Network Channels (A / B)
- Terminals 11–16: Discrete emergency output relay contact outputs (Wrong Way Alarm, Power Failure)
- Grounding Lug: Threaded brass grounding point on the rear metal chassis plate
- Wire Gauge: Utilize minimum 0.75 mm² up to 1.5 mm² (18 to 16 AWG) multi-core shielded twisted pair marine cables for network links.
- Grounding Norms: Connect the cable drain wires directly to the common instrumentation bus bar on the console frame, preventing ground loops by grounding at only one side.
📡 Communication Configuration
- IP Address: Not applicable. This model relies entirely on serial fieldbus configurations or direct hardwired topologies rather than Ethernet infrastructure.
- Station ID: Programmed via binary DIP switch arrays situated on the rear processor board to identify its role (e.g., Bridge Master, ECR Slave, Wings Auxiliary).
- Baud Rate: Pre-synchronized factory profile operating at standard 9600 bps or 19200 bps to interface with the central AutoChief communication network.
❓ Frequently Asked Questions (Q&A)
- Q: What does a flashing “Wrong Way” indicator mean on the ETU 001?
- A: This indicates a critical conflict where the physical direction of the main engine shaft does not match the command direction requested by the bridge telegraph lever.
- Q: Can the internal buzzer volume be customized?
- A: Yes, a potentiometer located on the rear interface board allows the installation technician to adjust the internal buzzer intensity to match ambient background machinery noise.
- Q: How does the unit respond if the primary 24V DC ship supply drops out?
- A: The ETU 001 automatically switches over to the auxiliary backup battery bank line instantly without resetting, triggering a visual “Power Failure” warning light across all synchronized panels.
