The core business of Kwant Controls is the design and manufacturing of various types of control units for the electrical remote control of practically all kinds of propulsion and steering devices, such as: traditional main engine/clutch/CPP-FPP shaft lines, tunnel thrusters, azimuthal thrusters, rudders and water jets.

  • Most units can be equipped with drive motors for automatic lever synchronization in a multi-station electric shaft/telegraph system.
  • Various machinery interfaces can be selected from e.g. potentiometer, 4-20mA, micro-switch contacts or even integrated CAN.
  • In case of remote control failure, one can rely on our traditional lamp type Engine Order Telegraphs, for signalling between Bridge, Control- and Engine Room.
  • Feedback from the vessel’s actuators can be displayed using our panel- or ceiling mounted range of indicators.
  • Customer specific control panels, with built-in lever units, signal lamps, pushbuttons, indicators, buzzers, electronic dimmers et cetera can be supplied. These panels are available with interface modules and PLC’s, together forming a Propulsion Remote Control system tailored to customer requirements, completely functional Factory tested (with or without class and/or customer in attendance).
  • For maximum flexibility of control on board, and eliminating the need for having fixed control positions, class approved portable wireless control systems can be supplied with all control devices integrated.


The telegraph systems are supplied with potential free contacts for data logging (voyage data recorder) for each command, and for telegraph alarm, power failure and station on service (in case more than one receiver/transmitter is used).

The default execution has the following engraved telegraph commands:

  1. Full Ahead
  2. Half Ahead
  3. Slow Ahead
  4. Dead Slow Ahead
  5. Finished With Engine (FWE)
  6. Stop
  7. Standby (STBY)
  8. Dead Slow Astern
  9. Slow Astern
  10. Half Astern
  11. Full Astern

To send an order from the wheelhouse to the engine (control) room receiver/transmitter, the control knob of the wheelhouse transmitter/receiver has to be put in the position corresponding with the required order. A visible and audible intermitting alarm will now come into operation.

On the wheelhouse transmitter/receiver the requested order is indicated by means of a flashing signal lamp, while at the same time a continuously lit signal lamp shows the position of the receiver/transmitter knob in the engine (control) room. In order to acknowledge the requested order, the knob should be rotated to the position of the flashing signal lamp, after which the alarm will stop.

The audible alarm on the wheelhouse consists of an internal buzzer, while for engine (control) room a external gong or claxon can be supplied. The wheelhouse transmitter/receiver is supplied with a dial illumination and dimmer.


  • Horns, gongs and/or claxons for audible alarm;
  • Rotating mirror beacon for optical alarm;
  • Additional (potential free) contacts for specific applications;
  • Also available in 9 commands i.e. without FWE and STBY.
