Prerequisites
The CS90 is installed as specified in this manual.
|
• |
The door on the Transceiver Unit is removed. |
|
• |
The door on the Motor Control Unit is open. |
You must be equipped with a standard set of tools. This tool set must comprise the normal tools for electronic and electromechanical tasks.
Context
Certain steps in the two procedures are location specific. The steps marked [Bridge] are done on the bridge.
Procedure
|
1 |
[Bridge] Make sure that you have sufficient water depth below the keel before you lower the transducer. |
|
2 |
[Bridge] Turn on the CS90. |
|
3 |
[Bridge] Lower the transducer to its middle position.
|
a |
[Bridge] On the Operating Panel, press Middle. |
|
b |
When the transducer shaft stops, make sure this happens at the correct middle position. |
|
|
4 |
[Bridge] On the Horizontal menu, set Range to a suitable range. |
|
5 |
[Bridge] Set Mode to Bow Up. |
|
6 |
[Bridge] Start "pinging".
|
a |
[Bridge] Set Tx Power to Low. |
|
b |
[Bridge] Verify that echoes appear on the CS90 presentation. |
|
c |
Make sure that all the 16 transceiver boards are fully functional.
Each transceiver board is fitted with several LED indicators. To verify normal operation, check the LED activity on all transceiver boards simultaneously. During normal operation, they will behave nearly identical. If the LEDs on one board act suspicious related to the other boards, you may have an error.
|
|
d |
If possible, verify that you can hear the sound of the transmit pulse from the transducer. |
|
e |
[Bridge] Set Tx Power to Medium. |
|
f |
[Bridge] Verify that echoes on the CS90 presentation appear stronger. |
|
g |
If possible, verify that the sound of the transmit pulse is louder. |
|
h |
[Bridge] Set Tx Power to Maximum. |
|
i |
[Bridge] Verify that echoes on the CS90 presentation appear even stronger. |
|
j |
If possible, verify that the sound of the transmit pulse is even louder. |
|
|
7 |
[Bridge] Set TX Power to Off. |
|
8 |
[Bridge] On the Operating Panel, press Up. |
|
9 |
When the transducer shaft stops, make sure this happens at the correct middle position. |
|
10 |
[Bridge] Notify the sonar room that the test is finished. |
|
11 |
Close the door on the Transceiver Unit.
|
a |
Place the door on its frame. |
|
b |
Tighten the four bolts that secure the door. |
|
|
12 |
Close the door on the Motor Control Unit. Use a spanner to secure it. |
