Context
When you move the cursor over the matrix presentation of the transceiver channels, each element in the transducer can be clearly
identified as a rectangle. If you place the cursor on top of one of these rectangles, a small yellow tool-tip will identify key information.
A rectangle with 32 black elements in the matrix view indicates a failure with a single transceiver board. The tooltip will indicate which board that fails. Restarting the ME70 system will normally fix the problem. Failure of eight or nine consecutive transceiver boards indicates a problem with the power supply.
|
• |
Weak signals indicate a problem with the +6 VDC supply voltage to the analogue amplifiers. |
|
• |
No response indicate a problem with the +12 VDC supply voltage to the digital circuitry. |
|
• |
A failure in the +75 VDC supply voltage can only be detected in the transmit test. |
Result
If single elements, or groups of elements, report signal levels with abnormal deviation from it's neighboring elements, this
indicates malfunctioning receiver hardware. If the transmit test for the elements in question works well this indicates a
bad cable connection to the transducer.
Possible reasons may be:
|
• |
Bent or broken pins between the transceiver backplane and the transceiver board or transceiver interface board for the relevant
element. |
|
• |
Bent or broken pins in the cable connector into the transceiver interface board for the relevant element |
|
• |
A defective transducer element. |
