Important
The SY50 is an advanced product. It is used with other advanced products. There is important information that you need to know.
Hoisting motor without brake
It is crucial that the power to the hull unit is always turned on, even when the sonar is not in use. If the power is turned off, the force of gravity may cause the transducer to be inadvertently lowered. The sonar has a safety function that will automatically hoist the transducer if unexpected problems arise. This function prevents the transducer from being lowered when the sonar is not used, but the power must be turned on.
Before you turn on the SY50 system
Before you turn on the SY50 system, make sure that you have sufficient water depth to lower the transducer!
Caution
You must never turn on the SY50 system when the ship is in dry dock. The transducer can be damaged if it transmits in the open air.
When the SY50 system is not used
When you do not use the SY50 system, turn it off.
Note
You must never turn off the SY50 system by means of the on/off switch on the Processor Unit. You must ALWAYS use the Operating Panel.
When you are docking your vessel
You must never set the SY50 system to normal operation when the ship is in dry dock. The transducer can be damaged if it transmits in the open air. To prevent inadvertent use of the SY50 system, pull out the mains plug on the Processor Unit whenever your vessel is in dry dock. Additional precautionary measurers should be considered.
If something breaks down
If you believe that something has broken down, contact your local dealer. A list of all our dealers is provided on our website.
If you are unable to contact a dealer, observe the support information in this publication.
When you want to turn off the SY50 system
You must never turn off the SY50 system by means of the on/off switch on the Processor Unit. When you do not use the SY50 system, turn it off with the Power button on the Operating Panel. If the transducer is lowered when you turn off the SY50 system, it is automatically retracted to its upper position.
Note
If you turn off the SY50 system by means of the on/off switch on the Processor Unit you can damage the software and the interface settings used to communicate with external devices.
Manual operation of the hull unit
In the event of improper operation, the powerful electric motor on the hull unit may cause serious damage to the equipment and/or injury to personnel. Therefore, before you start manual operation, read carefully through the relevant operating procedures.
Note
You must familiarize yourself with the correct handling methods and the relevant safety requirements.
Rules for transducer handling
A transducer must always be handled as a delicate instrument. Incorrect actions may damage the transducer beyond repair. A physical blow to the transducer face may easily damage one or more elements. Observe these transducer handling rules:
•  Do not activate the transducer when it is out of the water.
•  Do not handle the transducer roughly. Avoid impacts.
•  Do not expose the transducer to direct sunlight or excessive heat.
•  Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer.
•  Do not damage the outer protective skin of the transducer.
•  Do not step on the transducer cable.
•  Do not damage the transducer cable. Avoid exposure to sharp objects.
