General Information
ELECTRO–TYFON®MT 150/130 is an electrically driven
piston ship’s whistle. It is built up of comparatively few
moving parts as the “swinging piston”, no lubricated cylinder
and an oil free gearbox.
Important features:
• unsymmetrical sound distribution
• operates in all ambient temperatures without any
additional measures
• una󰀨ected by voltage and frequency uctuations
• oil free, maintenance free and non–corrosive
• easy to install
• complies fully with the International Regulations
IMO 1972 Technical Data
ELECTRO-TYFON
Operates in all temperatures without any
additional measures
ELECTRO–TYFON®MT 150/130 will give a high
performance in both arctic and tropical climates.
A patented system with a high e󰀩ciency rectangular
horn and a specially designed motor will match the motor
speed to the acoustic resonance of the horn at any
ambient temperature without any additional measures.
This system also prevents the whistle from being a󰀨ected
by voltage and frequency uctuations in onboard mains.
Unsymmetrical Sound Distribution
The IMO Regulations stipulate a very high Sound
Pressure Level for e󰀩cient signaling, yet the sound level
of the vessel's own signal at the listening posts shall not
exceed 110 dBA.
A common way to solve this “paradox” is to place the
whistle very high above deck. But what if the highest point
is not high enough? For example: to reduce the noise
from the signal by 6 dB, the distance between the
listening post and the whistle must be doubled!
ELECTRO–TYFON®MT 150/130 with Unsymmetrical
Sound Distribution is the solution. The horn with its unique
vertically extended front, and a specially created sound
spectrum will reduce the noise on deck with 6–8 dB
compared to a conventional whistle with circular orice.

Dimensions, Installation and Maintenance
Motor Control
Kockum Sonic’s Contactor Unit TK 80 is especially developed
to control the ELECTRO-TYFON®MT / MTX series
Functions:
• Motor start
• Motor overload protection
• Winding heating of motor for anti-condensation purpose.
For full description see data sheet KSM742.
Installation
ELECTRO–TYFON®MT 150/130 shall be xed with four
M12 screws that must be rmly 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,
exible 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.
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 ber armed polyester (white).
The cylinder is non lubricated and the gearbox is entirely
oil free.
ELECTRO-TYFON® MT 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. At least annual inspection is advisable.
In very harsh conditions, and high running time, increase
frequency accordingly.
See “Inspection, troubleshooting and refurbishing”.

Inspection, Troubleshooting and Refurbishing
Fig 1 Fig 2 Fig 3 Fig 4 Fig 5
Inspection
The MT/MTX-series Electro-Tyfon is a maintenance free design, but periodic inspection is advisable to get an early
indication of faults that might develop.
At least annually, but in conditions with high/very high signaling frequency, increase inspection rate accordingly.
See below instruction:
Remove cover (figure 1 below)
1. Rotate crank shaft / piston rod / piston assembly by the counter weight. It should rotate smoothly, with little friction.
2. Inspect mechanical parts; Piston, counterweight bolts, piston rod lid / screws. Is everything in place and secured?
3. Inspect for grease leakage. Mainly piston rod radial seal, but also crankshaft bearing.
Troubleshooting
Eliminate possible power failure. Check all 3 phases.
• Low insulation? Check junction box for water ingress. Check motor windings.
Motor is not running? Check motor windings for interruption, short circuitry (insulation error).
• Motor running but no sound? Check mechanical parts.
• Motor is running but weak sound? If newly installed; Check spec./ mains correlation.
Check motor windings, all 3 Ok? Check mechanical parts. All parts ok and secured?
Crank/rod/piston assembly rotating smoothly?
• Abnormal noise, rattling? Inspect mechanical parts, mainly piston / rod. Ok and secured?
• Abnormal vibration? Check dampers. Stud bolts and nuts secured, and damper slightly compressed?
Check mechanical parts, mainly counter weight.
Refurbishing / mechanical work
To access some of the refurbishing points, such as piston, piston rod, motor, it’s necessary to dismount the “compressor unit”.
1. Dismount screws and remove cover.
2. Dismount screws and remove complete “compressor unit”. Now you have access to the piston.
3. Dismount piston bolt, counter holding piston rod (to avoid stressing rod bearing), and remove piston.
4. Dismount screw and remove base plate. At this state you have access to the piston rod.
5. Dismount motor bolts and remove motor. At this state you have access to the gearbox,
enabling change of crankshaft / gearwheel or bearings, and to the motor, enabling changing motor and/or gearwheel.
It’s advisable to replace used locking nuts. All other bolt and screw joints shall be re-secured with locking liquid.
NOTE! Our 380/440V spare motors are as
default set to 380/440V.
If your supply is 230V we could adapt the
setting on demand.
Otherwise, it's easily done by this illustrations.
