Motor Control

Kockum Sonic’s Contactor Unit TK 80 is especially developed to control the Electro–Tyfon  MTX 150/130

Functions:

• Motor start

• Motor overload protection

•  Winding heating of motor for anti-condensation purpose.

Dimensions, Installation and Maintenance

Installation

Electro–Tyfon  MTX 150/130 shall be fixed with four M12 screws that must be firmly tightened and locked.

Mount the whistle on a platform supplied with a safety rail. As the whistle is subject to vibration on starting and stopping,

flexible electric cables should be used nearest the motor. The gland on the electric Motor Terminal Box is M 32 for

cable Ø 17 - 28 mm.

Optional: M 25 for cable Ø 9-20 mm.

Recommended power cable section:

For cable length up to 100 m       Ø 4  ㎜²

For cable length over 100 m        Ø 6  ㎜²

Recommended fuses slow 20A

Maintenance

All components are chosen to withstand corrosion and to give a minimum of maintenance.

The crankcase and foundation is hot galvanized. The motor is marine coated - Marine C4 class.

The horn is made of glass fiber armed polyester (white).

The cylinder is non lubricated and the gearbox is entirely oil free.

Electro–Tyfon  MTX 150/130 is designed to give long reliable service without routine maintenance,
but a periodic inspection always gives early warning of any faults that may develop

Trouble shooting and refurbishing

Prior to any work on the unit disconnect power.

Eliminate possible power failure; check the voltage of every phase on motor wire terminals.

Important:

• The motor(driver)is always delivered with the driving gear wheel mounted on the shaft.

• Do not reuse the old gear wheel,it is made of bakelite and pressed with tight fit and may be damaged when remo-
  ved/remounted.

• Lubricate the teeth ofthe gearwheels with the grease enclosed in the set.

• Change always piston and piston rod together.When loosening and retightening the piston screw counter hold with a
  spanner on the flat surfaces of the piston rod just above the piston to avoid twisting the rod.

• Lubricate the piston rod bearing and fil half of the volume inside the bearing cover with high-speed roller bearing
  grease enclosed in the set.

• The gear shaft as spare part is delivered complete with front bearing and gear wheel. Do not remove rear bearing if not necessary,it is fixed in the crank case.

• Do not reuse the steel gear wheel,it is warm pressed with very tight fit and may be damaged when removed/remoun-ted.

• On inspecton or change of parts,always replace O-rings,circips,the piston rod sealing ring with new ones.
  

• Lock all screws with Loctite 242or similar locking liquid.

Sound Performance
This electrically driven piston ship whistle provides strong sound pressure within the frequency range specified for marine sound signaling. The sound output is suitable for use as a primary marine whistle and fog horn, ensuring clear external warning signals even in fog, rain, or high background noise conditions.
The acoustic design allows the vessel whistle to maintain effective signal transmission over long distances while keeping deck noise at a controlled level, supporting safe and practical onboard operation.

Technical Design
The ship whistle adopts an electrically driven piston mechanism instead of a traditional compressed-air system. This structure simplifies the overall system design and removes the need for air compressors, pipelines, and air tanks.
As an electrically driven piston ship whistle, it contains fewer mechanical components, which improves operational stability and reduces mechanical wear during long-term marine service.

Compliance and Standards
This marine whistle is manufactured in accordance with the International Regulations for Preventing Collisions at Sea (COLREG 1972) and IMO sound signal requirements.
It is suitable for installation as an approved ship whistle, vessel whistle, and fog horn on commercial vessels where compliance with international maritime regulations is mandatory.

Installation
The ship whistle is designed for straightforward installation on vessel decks or superstructures. Its electrical operation allows easy integration with standard onboard power systems.
This marine whistle can be used for both new ship construction and retrofit projects where an existing fog horn or vessel whistle needs to be replaced with an electrically driven system.

Reliability and Maintenance
The electrically driven design eliminates the complexity of pneumatic systems and reduces routine inspection work. There is no requirement for air supply equipment, lubrication systems, or pressure control devices.
This makes the electrically driven piston ship whistle a low-maintenance solution with high long-term reliability, particularly suitable for vessels operating continuously under demanding marine environments.

Working Principle
‑ Pneumatic Whistle: Compressed air enters chamber to vibrate diaphragm; horn amplifies acoustic output.
  TV784 valve unit controls air circuit, equipped with filter, heating and emergency lanyard operation.
‑ Electric Electro‑TYFON: Motor‑driven piston generates sound. Patented temperature‑sensitive speed
   adjustment automatically compensates ambient temperature & ship power‑supply fluctuation. No
   compressed‑air source required.

Application Scenarios
Ocean‑going merchant vessels, bulk carriers, container ships, tankers, work‑boats, tugs, ferries, offshore platforms; large inland waterway vessels. IMO mandatory fog signal, navigation manoeuvre acoustic signal, fog‑day warning.
