6.2 The Sonar Control Unit cabling

All the cables to the Sonar Control Unit are to be plug connected

to the electronic drawer unit at the rear of the cabinet (see figure

13). The numbers on the figure refer to the cable numbers on the

cable plan.

Note ! In order to make service on the Sonar Control Unit, the cables must have

a slack so the electronic drawer unit can have all the cables connected

while it is outside the cabinet. This could be either by pulling it out from

the front, or by reconnecting the cables with the drawer at floor level.

Note that cable no. 4 (refer to figure 12) is delivered with a

standard length of 50 meters, and has a preconnected plug in the

Sonar Control Unit (wheelhouse) end.

j Pull cable no. 4 from the wheelhouse to the sonar room.

Note that the preconnected plug should be connected to

the Sonar Control Unit in the wheelhouse. Remember to

include the slack for service purpose.

j The mains power cable (3) may be connected to a normal

mains outlet in the wheelhouse. If the delivered cable

does not fit, put on a suitable connector. Note that the

mainspowertotheSonarControlUnitcanbe115VACor

230 VAC, and that this unit will automatically sense the

voltage.

The connection of the speed log (1) and the course gyro (2) will be

described in chapter 7.
