Description
📝 Product Overview
The Kongsberg Lilaas LF70R-01-53 is a premium, marine-certified single/dual-axis control lever designed for precise propulsion, thruster, and winch control on commercial vessels. Built with marine-grade aluminum and equipped with contact-free potentiometer or optical encoder technology, this control lever delivers exceptionally smooth operation, high mechanical durability, and reliable command transmission to the ship’s main propulsion or dynamic positioning system.
⚙️ Technical Specifications
- 📐 Dimensions: 130 mm x 130 mm x 195 mm (Above panel height; console depth: 110 mm)
- ⚖️ Weight: 2.10 kg
- 🌍 Country of Origin: Norway
🚢 Applications
- Marine propulsion systems (Main engine RPM and pitch control)
- Bow, stern, and azimuth thruster manipulation
- Dynamic Positioning (DP) manual override stations
- Offshore winch and heavy deck machinery speed regulation
🛠️ Usage Instructions
- Test the spring-return mechanical centering action or friction detent drag settings prior to system calibration.
- Move the lever smoothly through its gate stroke; avoiding rapid slamming from full-ahead to full-astern to protect structural components.
- Periodically inspect the perimeter of the lever boot seal to prevent large debris or excessive standing water from collecting around the base.
- Ensure control handover procedures between bridge wings and the center console are fully acknowledged by the automation system before moving the lever.
🔧 Mechanical Installation Requirements
- Fixing Method: Flush console mounting via four M5 stainless steel counter-sunk screws placed through the integrated top-plate corner bevels.
- Space Clearance: Maintain a minimum clear clearance depth of 130 mm beneath the mounting console plate to ensure unhindered wire harness movement.
- Heat Dissipation: Passive air cooling. Ensure the console interior stays dry, well-ventilated, and maintains an ambient thermal profile under 55°C.
🔌 Electrical Wiring Guide
- Terminal Definitions: * Pin 1: +5V DC Sensor Reference Voltage Supply
- Pin 2: Analog Output Signal (0-5V or 4-20mA proportional loop)
- Pin 3: Signal Ground / Return
- Pin 4-5: Integrated Microswitch common and normally open contact (Neutral interlock)
- Shield: Braided shield grounding tail
- Wire Gauge: Use minimum 0.5 mm² to 0.75 mm² (20 to 18 AWG) multi-core shielded marine cable for low-voltage sensor outputs.
- Grounding Norms: The cable’s tinned copper shield mesh must be grounded at the receiver end (PLC or drive controller) to eliminate analog signal jitter caused by adjacent EMI sources.
📡 Communication Configuration
- IP Address: Not applicable. This model utilizes direct analog signaling or integrated CAN/Profibus nodes depending on the built-in circuit module configuration.
- Station ID: Configured via onboard micro-DIP switches located directly on the underside interface card if the unit is ordered with a serial/fieldbus bus interface option.
- Baud Rate: Pre-configured factory presets (typically 250 kbps or 500 kbps) when operating as a native CANopen node inside distributed vessel networks.
❓ Frequently Asked Questions (Q&A)
- Q: Can the friction or movement resistance of the handle be adjusted?
- A: Yes, mechanical friction adjustment screws are accessible beneath the top plate assembly, allowing operators to fine-tune handle resistance.
- Q: What is the benefit of the contact-free potentiometer used in this lever?
- A: The contact-free design eliminates mechanical wear and tear on electrical tracks, providing a significantly longer operational lifespan and reducing signal drift over time.
- Q: Why is the control system reporting a “Signal Out of Range” fault for this lever?
- A: This usually points to a broken supply wire (+5V or Ground), a faulty sensor element, or an incorrectly calibrated zero-point offset within the receiver module.
