A transducer must always be handled as a delicate instrument. Incorrect actions may damage the transducer beyond repair. Observe these transducer handling rules:
|
1 |
Do not activate the transducer when it is out of the water. |
|
2 |
Do not handle the transducer roughly and avoid impacts. |
|
3 |
Do not expose the transducer to direct sunlight or excessive heat. |
|
4 |
Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer face. |
|
5 |
Do not damage the outer protective skin of the transducer face. |
|
6 |
Do not lift the transducer by the cable. |
|
7 |
Do not step on the transducer cable. |
|
8 |
Do not damage the transducer cable, and avoid exposure to sharp objects. |
Transport protection
Some transducers are delivered with a cover plate to protect the face during transport and installation. Let this plate stay on as long as possible, but do not forget to remove it before the vessel goes to sea.
Cleaning and painting the transducer face
During normal use, the transducer is subjected to biological fouling. If this marine growth is excessive, it will reduce the performance of the ES38DD.
The transducer has not been designed with any protection against biological fouling. Whenever opportunity arise, typically when the vessel is dry-docked, the transducer face must be cleaned for shells and other marine growth.
|
• |
Be careful so that you do not accidentally make cuts or inflict other physical damage to the transducer face. |
|
• |
Remove biological fouling carefully using a plastic brush, a suitable synthetic detergent and fresh water. Biological material which is strongly rooted in the substrate can be removed carefully with a piece of wood or plastic. |
|
• |
Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer. |
Anti-fouling paint may be applied to the transducer face. To minimize the negative acoustical effects the layer of anti-fouling paint must be as thin as possible.
NoteThe anti-fouling paint will reduce the acoustical performance of the transducer. The surface roughness of the transducer substrate and the thickness of the paint may also influence the performance. Kongsberg Maritime cannot be held responsible for any negative consequences of the anti-fouling paint.
Because some paint types may be aggressive to the polyurethane in the transducer, consult our list of approved paints. The list can also be found on http://www.simrad.com. Observe the relevant instructions and safety information provided by the paint manufacturer.
