- Introduction: The Aqua Signal navigation lights control unit (Model: E3425504000-8306) is engineered for marine navigation safety, delivering reliable centralized switching, real-time lamp monitoring, and seamless integration across vessel bridge automation architectures.
Product Parameters & Datasheet
- 📐 Dimensions: Standard marine bridge console-mount enclosure measuring approximately 300mm x 200mm x 120mm.
- ⚖️ Weight: Approximately 3.5 kg.
- 🌍 Country of Origin: Germany / European Union.
- ⚡ Power Supply Rating: Dual redundant 24 VDC and 115/230 VAC ship mains supply inputs.
- 🔧 Installation Style: Panel flush-mounting or console bulkhead installation.
- 🌡️ Operating Temperature: -10^\circC to +55^\circC.
- 湿度 Humidity: Up to 95% non-condensing relative humidity in marine bridge environments.
- 🛡️ Ingress Protection: IP22 rated for protected bridge control console environments.
- 🔌 Communication Interface: NMEA 0183 / serial alarm output ports and volt-free remote monitoring contacts.
- ⚡ Power Consumption: Maximum 30 W under full operational load with all channels active.
Application Fields
- Commercial cargo vessels, container ships, and oil tankers.
- Passenger ferries, cruise liners, and mega yachts.
- Offshore support vessels and specialized marine research ships.
- Naval auxiliary craft and port authority patrol boats.
Product Precautions
- Verify that both primary and secondary power supply feeds match the unit’s rated voltage specifications prior to initial energization.
- Ensure all navigation light output circuits are properly fused and free from short circuits before activating channel switches.
- Inspect terminal connections periodically for salt mist corrosion or mechanical loosening caused by vessel vibration.
- Clean the front facia and indicator panels using non-abrasive, anti-static cleaning cloths to maintain clear visual status monitoring.
Parameter Configuration & Modification Methods
- System settings, alarm thresholds, and channel assignments are managed via internal configuration jumpers and dip-switches or through dedicated software tools depending on the specific software-monitored generation.
Manual/Automatic Mode Switching
- Transitioning between manual front-panel switch operation and automated external bridge alarm integration or day/night dimming modes is handled via dedicated front-panel toggle buttons and integrated control logic.
Emergency Trip / Alarm Operation
- Lamp Failure Alarm: In the event of a bulb burnout or open-circuit fault on any connected navigation light, the unit instantly triggers an audible buzzer and optical alarm on the bridge, automatically switching to the secondary supply or backup indicator circuit where applicable.
Frequently Asked Questions (Q&A)
- Q: How does the unit detect a failed navigation light?
A: Internal current-sensing circuits continuously monitor the current draw of each active channel, triggering a fault alarm if the current drops below the calibrated threshold.
- Q: Can the control unit be powered by dual independent sources?
A: Yes, the unit supports automatic switchover between main and emergency ship power feeds to ensure uninterrupted navigation light operation.
- Q: Are external alarm panels supported?
A: Yes, integrated relay output contacts allow connection to the central vessel alarm monitoring system (AMS) or bridge navigation alarm systems.
