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.
Products
- 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.
BUK-B
The BUK-B is the largest console mounted propulsion control lever unit of the BUK-series, with a well-recognized, widely applied and much appreciated classic appearance. It is also the most versatile lever unit of the BUK family, offering a practically unlimited number of variations when it comes to user- and machinery interfaces. A maximum of 10 HMI pushbuttons/buzzers/signal lamps/dimmers can be incorporated, and a wide range of electrical machinery interfaces is available.
Specs
The unit is made of a seawater proof aluminium alloy, executed with two side dials and one peripheral dial. The dials are protected by means of an unbreakable, transparent and UV proof protective cover. All decorative parts of the housing are black anodized. The lever unit can be supplied with single or twin levers and with spherical knobs or cross bars. The basic signal transmitter is a 2KOhm potentiometer that returns 10-90% of its supply voltage over the full lever travel of 120°.

BUK-G mk2 (IP68)
The BUK-G mk2 is the IP68 level model of the BUK-G and has been especially designed for applications in yachting. It has a slightly different shape compared to the standard BUK-G, to be protected from immersion in water with a depth over 1 meter. The BUK-G mk2 is suitable for both propulsion and transverse thruster control. The basic signal transmitter is a 2KOhm potentiometer that returns 10-90% of its supply voltage over the full lever travel of 120°.

EOT: “Push button” type
The “Pushbutton” type of Engine Order Telegraphs consist of a row of up to 12 (default =11) interlocked pushbuttons, mounted in a black anodized aluminium panel with dimensions 96x288mm.
Each telegraph has a pushbutton for lamp test, all lamps can be replaced from the top by removing an individual lamp cap. The bridge telegraph has a dimmer to control the lamp brightness. The audible alarm is generated by an internal buzzer. For those areas where a higher sound level is required, external horns and gongs can be supplied.

BUK-H
The BUK-H has been designed with a zero build-in depth, for the desktop mounted shape with potentiometers. It is also suitable for transverse thruster control due to its symmetrical and therefore applicable in various orientations. The basic signal transmitters are dual 5KOhm potentiometers that return 10-90% of the supply voltage over the full lever travel of 120°.

Integrated telegraph system
The control units of the types BUK-B, BUK-C and Pointer WD can be supplied with an analogue integrated emergency telegraph system of the ‘pointer’ type. The BUK-B in the twin lever execution can be equipped with twin pointer telegraph systems, whereas the BUK-C only has room for a single system. The pointer telegraph is a communication system designed to send orders from the bridge or bridge annexes to the engine room or engine control room. Whenever a new command is being issued, the telegraph alarm will be switched on. In order to mute the alarm, the command must be acknowledged at the selected position by moving the control lever to the position requested.
Precision potentiometers are used to transmit the orders. DC servo motors (RSM4) are used for moving the pointers along the scales of the control units. The system can be switched from telegraph mode to Remote Control (RC) mode by means of a single contact. In RC mode, the telegraph alarm is disabled. The wheelhouse unit’s reply pointer is now connected to its own command lever. RC mode is used to control the main engine directly from the wheelhouse by means of signal transmitters e.g. a potentiometer or 4-20mA module.

BUK-C
The BUK-C is the second largest console mounted propulsion control lever unit of the BUK-series, with a well-recognized, widely applied and much appreciated timeless classic appearance. The lever unit comes in a number of variations for user- and machinery interfaces. In the BUK-C extended version, a maximum of four HMI pushbuttons/buzzers/signal lamps/dimmers can be incorporated, as well as a wide range of electrical machinery interfaces. The BUK-C special version, is typically suitable for transverse thruster control.

EOT: “NORM” type
The “Norm” type telegraph has been designed to be used on board of all types of vessels having a remotely controlled propulsion control, and serve as the back-up communication system in case the remote control system should fail. The wheelhouse and engine control room telegraphs are console mounted, IP42, 144x144mm devices, and have a stainless steel housing and a non-reflective black finish. An IP56 housing is available for bulkhead mounting applications such as the Engine Room.
