Installing the CS90 sonar room cables
The sonar room cables include those used to connect the CS90 units to AC mains power, as well as the control cables between the units. Two high capacity Ethernet cables connect the Processor Unit to the Transceiver Unit.
Context
All sonar room cables are described.
Procedure
1 Prepare the power cables, but do not connect any units to AC mains power.
a Connect the power cable from the uninterruptible power supply (UPS) to the AC power outlet. (C23)
b Connect the power cable from the Transceiver Unit to the power outlet on the uninterruptible power supply (UPS). (C22)
c Connect the power cable from the heat exchanger to the power outlet on the uninterruptible power supply (UPS). (C31)
Standard commercial AC mains cables are used. Each cable is supplied with the relevant unit. The typical cable length is between 1,5 and 2 meters. If this is too short you must use an extension cable (not recommended), mount a new power outlet within range, or make your own power cable with sufficient length.
For more information, see the cable details:
2 Connect the ground cable from the Transceiver Unit to vessel ground.
The grounding cable for the Transceiver Unit is not listed. The grounding cable is a special braided wire that is physically connected to the cabinet. It is connected to vessel ground by means of the cabinet’s shock absorbers.
3 Connect the ground cable from the hull unit mounting flange to vessel ground. (C20)
A dedicated grounding cable is provided with the hull unit. One end of the cable is already fastened to the hull unit mounting flange. The other end must be connected to vessel ground close to the hull unit. The length of the cable is 2 metres. Use 16 mm bolts or screws.
4 Connect the Ethernet cable from the Transceiver Unit to the Motor Control Unit. (C26)
5 Connect the power cable from the Motor Control Unit to the AC power. (C28)
For more information, see the cable details:
6 Connect the control cable from the Motor Control Unit to the gate valve and the Gate Valve Control Unit. (C21)
This connection is only required if the optional hydraulic gate valve is installed. This interface prevents the transducer to be lowered while the gate valve is closed. It also prevents the gate valve from closing when the transducer is lowered.
For more information, see the cable details:
7 Prepare the installation of the transducer cable. (C27)
The transducer cables are connected to the Transceiver Unit using a large transceiver 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 transmitting (‘pinging’) with the CS90.
a Make sure that the transducer cable is long enough to allow the transducer to be lowered and hoisted without causing any damage to the cable.
b DO NOT connect the transceiver plug to the socket on the Transceiver Unit.
Note
This connection is made as a part of the Setting to work procedures.
