The ELAS-5 electric shaft system combines telegraph and electric shaft functions, using stepper motors and CAN bus technology for improved flexibility and reduced installation time.

Applications

  • marine propulsion control

Features

  • stepper motor driven levers
  • CAN bus technology
  • programmable detents
  • haptic feedback
  • fine adjustment

Options

  • central take over
  • tandem mode
  • electrical fine adjustment
Inspection

Inspector Detail

Common issues

  • Feedback discrepancy between a control station's lever position and the actual propulsion order, usually traced to a worn or drifting feedback potentiometer
  • Loss of follow-up signal caused by broken, chafed or corroded control cabling between stations
  • Indicator lamp or LED failure on telegraph repeaters, which can mask a valid order being missed
  • Sticking or worn lever mechanism reducing the smoothness and repeatability of order transmission
  • Calibration drift after a power interruption or backup battery failure on the control system
  • Joystick or combined docking-control module fault causing loss of a combined steering/thrust command
  • Moisture or condensation ingress into control station housings on exposed bridge wings

Inspection checklist

  • Function test each control station (wheelhouse, bridge wings, engine control room, local) against the actual propulsion/thruster response
  • Transfer test between control locations, confirming only one station has command at any time and the changeover is unambiguous
  • Lamp and alarm test on all telegraph and order repeaters
  • Check follow-up indicator accuracy against actual pitch, rpm or thruster angle
  • Verify the emergency/backup and local-at-the-machine control changeover procedure
  • Inspect cabling, glands and connectors at each control station for corrosion or mechanical damage
  • Confirm the control system's backup battery/UPS holds charge and switches over automatically on mains loss

Service intervals

Full function test of all control stationseach watch change or before departure, per company PMS
Calibration check of lever and feedback potentiometersannually or per maker recommendation
Cable and connector inspection at each stationannually
Backup battery/UPS function testannually, with battery renewal per the battery manufacturer's stated service life

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Lever position repeatabilityelectronic follow-up systems should track actual response within the tolerance stated in the system manual - a generic figure is not meaningful here, confirm against the manufacturer's commissioning data
Connector/contact resistanceany measurable rise from the as-installed baseline points to corrosion and should be investigated rather than compared to a single fixed number

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Control lever assembly
  • Feedback potentiometer
  • Indicator lamp / LED module for repeaters
  • Control station circuit board (confirm exact revision with the maker before ordering)
  • Multicore control cable
  • Backup battery or UPS unit

Safety

  • Loss of propulsion or steering command during maneuvering if the system fails without a working emergency backup
  • Ambiguity between control stations if the transfer/interlock function is faulty - always confirm which station actually has command before assuming control
  • Electrical hazard when opening control station enclosures - isolate the supply before internal work
  • Bridge wing units are exposed to weather; live electrics behind a degraded gasket are a shock and fire hazard

Class survey

Note on this entry: the order data listed the category as 'Radar Level Gauge / Cargo Level & Temperature Gauging', but the actual product described (ELAS-5 electric shaft, telegraph system, CUBI(x), joystick, levers) is a bridge/engine-room propulsion and maneuvering control system, not a level gauging device. This entry has been written for the control system rather than the listed category. Propulsion control and telegraph systems are treated as continuous survey machinery; surveyors typically want to see a documented function/transfer test between all control positions and confirmation that emergency or local backup control works, carried out at each machinery survey.

Estimated lifetime: Electronic control and telegraph systems are not normally rated in running hours; service life is usually governed by electronic component obsolescence and cable condition, commonly on the order of 15-20 years before a full system renewal is considered - confirm current product support status with the maker

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
