Connecting the transducer cables to the Transceiver Unit
The transducer cables are connected to the Transceiver Unit with a large plug. The transceiver plug must be firmly connected to the side socket on the Transceiver Unit - and the transducer must be submerged in water - before you can start transmitting (‘pinging’) with the SU90 system.
Prerequisites
Image
We assume that you are equipped with a standard set of tools. This tool set must comprise the normal tools for electronic and electromechanical tasks. Each tool must be provided in various sizes. We recommend that all tools are demagnetized to protect your equipment.
Context
The transceiver plug must be firmly connected to the side socket on the Transceiver Unit - and the transducer must be submerged in water - before you can start transmitting (‘pinging’) with the SU90 system.
Caution
You must never permit the SU90 system to transmit (ping) when the ship is in dry dock. The transducer may be damaged if it transmits in open air.
Procedure
1 Make sure that the plug housing is clean and not damaged in any way.
2 Make sure that the gasket is clean and not damaged in any way.
3 Mount the transceiver plug.
a Hold the plug housing up to of the socket.
b Push the plug gently in place.
To avoid unnecessary strain on the connectors, push the plug straight in.
c Insert the bolts carefully. Make sure that each bolt fits to the threads.
Use the bolts and washers provided for the protective cover.
d Secure the plug with all the bolts provided.
Tighten the fastening screws evenly and a little at a time, alternating between screws on opposite sides of the plug, until all the screws are adequately tightened.
Note
Do not apply too much torque on the bolts, as this may damage the threads.
