Prerequisites
The MS70 hardware units are installed as specified in this manual. All cable connections are made according to the instructions in the installation procedures. Correct operating power is available.
The MS70 is switched off. You need the following test equipment:
WARNINGHigh voltages are used. This equipment must only be serviced by qualified personnel familiar with the construction and the operation of the MS70, as well as the potential hazards involved. Failure to observe this precaution could result in bodily injury.
Procedure
|
1 |
Verify that the MS70 units are correctly connected together. |
|
2 |
If your transducer is mounted on a drop keel, lower it into the water. |
|
3 |
Disconnect the power cables from the Power Connector Panels on the rear side of the TRXU subracks. |
|
4 |
Power Supply Units:
|
a |
Measure the output voltages with no load.
Measure the voltages on the terminal block in each Power Supply Unit.
|
|
b |
Verify that the measured voltages are within the permitted tolerances. |
|
c |
Adjust the voltage levels if necessary
|
|
d |
Repeat for each Power Supply Unit. |
|
|
5 |
Connect the power cables to the Power Connector Panels on the rear side of the TRXU subracks. |
|
6 |
Power up the MS70 from the Processor Unit. |
|
7 |
Verify that the Processor Unit and the Transceiver Unit start. |
|
8 |
Verify that the MS70 presentation appears after a few minutes. |
|
9 |
Verify that no error messages are presented during start-up. |
|
10 |
Power Supply Units:
|
a |
Measure the voltages with normal load.
Measure the voltages on the terminal blocks on the rear side of the Transceiver Unit.
|
|
b |
Verify that the measured voltages are within the permitted tolerances. |
|
c |
Adjust the voltage levels if necessary
|
|
d |
Repeat for each Power Supply Unit. |
|
|
11 |

|
e |
Set Ping Interval to 1 s. |
|
g |
Set TX Power to Maximum. |
|
|
13 |
Verify that echoes are shown on the MS70 presentation. |
|
14 |
