Prerequisites
The CS90 is installed as specified in this manual. The CS90 is turned on, and it is working normally. Neither tools nor instruments are required.
Context
Certain steps in the two procedures are location specific. The steps marked [Sonar room] are done in the sonar room.
Procedure
|
1 |
Make sure that you have sufficient water depth below the keel before you lower the transducer. |
|
2 |
[Sonar room] Locate the Motor Protecting Switch (S301). Set the switch to position ON. |
|
3 |
[Sonar room] Locate Hoist/Lower Switch (S302). Set the switch to position REMOTE. |
|
4 |
Lower the transducer to its middle position.
|
a |
On the Operating Panel, press Middle.
To indicate transducer movement, the Middle indicator lamp flashes, and an audible signal is sounded. When the middle position has been reached, the indicator lamp is lit, and the audible signal stops.
|
|
b |
[Sonar room] When the transducer shaft stops, make sure this happens at the correct middle position. |
|
|
5 |
Lower the transducer to its bottom position.
|
a |
On the Operating Panel, press Down.
To indicate transducer movement, the Down indicator lamp flashes, and an audible signal is sounded. When the bottom position has been reached, the indicator lamp is lit, and the audible signal stops.
|
|
b |
[Sonar room] When the transducer shaft stops, verify that the correct bottom position has been reached. |
|
|
6 |
Hoist the transducer to its middle position.
|
a |
On the Operating Panel, press Middle. |
|
b |
[Sonar room] When the transducer shaft stops, make sure this happens at the correct middle position. |
|
|
7 |
Hoist the transducer to its upper position.
|
a |
On the Operating Panel, press Up.
To indicate transducer movement, the Up indicator lamp flashes, and an audible signal is sounded. When the upper position has been reached, the indicator lamp is lit, and the audible signal stops.
|
|
b |
[Sonar room] When the transducer shaft stops, verify that the correct upper position has been reached. |
|
|
8 |
Lower the transducer to its bottom position.
|
a |
On the Operating Panel, press Down. |
|
b |
[Sonar room] When the transducer shaft stops, verify that the correct bottom position has been reached. |
|
|
9 |
Hoist the transducer to its upper position.
|
a |
On the Operating Panel, press Up. |
|
b |
[Sonar room] When the transducer shaft stops, verify that the correct upper position has been reached. |
|
|
10 |
Notify the sonar room to do the next step. |
|
11 |
[Sonar room] Locate Hoist/Lower Switch (S302). Set the switch to position STOP. |
|
12 |
Power down the CS90.
If the transducer is lowered when you turn off the CS90, it is automatically retracted to its upper position. The Transceiver Unit is turned off. The CS90 program closes down.
